Page 58: Sflow
The PowerConnect M6220, M6348, M8024, and M8024-k switches support sFlow version 5. For information about configuring managing sFlow settings, see "Monitoring Switch Traffic"...
Page 59: Stacking Features (Pcm6220, Pcm6348, And Pcm8024-K Only)
"Managing a Switch Stack" on page 143. High Port Count You can connect up to 12 PowerConnect M6220 switches or 12 PowerConnect M6348 switches in a single stack to increase the port count. The PowerConnect M8024-k supports high performance stacking for up to six systems using the 10G SFP+ ports.
Page 60: Master Failover With Transparent Transition
Master Failover with Transparent Transition standby The stacking feature supports a or backup unit that assumes the stack master role if the stack master fails. As soon as a stack master failure is detected, the standby unit initializes the control plane and enables all other stack units with the current configuration.
Page 61: Password-Protected Management Access
For information about configuring access and authentication profiles, see "Configuring Authentication, Authorization, and Accounting" on page 181. Password-Protected Management Access Access to the Web, CLI, and SNMP management interfaces is password protected, and there are no default users on the system. For information about configuring local user accounts, see "Configuring Authentication, Authorization, and Accounting"...
Page 62: Ssh/Ssl
SSH/SSL The switch supports Secure Shell (SSH) for secure, remote connections to the CLI and Secure Sockets Layer (SSL) to increase security when accessing the web-based management interface. For information about configuring SSH and SSL settings, see "Configuring Authentication, Authorization, and Accounting" on page 181. Inbound Telnet Control You can configure the switch to prevent new Telnet sessions from being established with the switch.
Page 63: Captive Portal
• Dynamic ARP Inspection: By default, if Dynamic ARP Inspection packets are received on a port at a rate that exceeds 15 pps for 1 second, the port will be diagnostically disabled. The threshold is configurable up to 300 pps and the burst is configurable up to 15s long using the ip arp inspection limit command.
Page 64: Dot1X Monitor Mode
Dot1x Monitor Mode Monitor mode can be enabled in conjunction with Dot1x authentication to allow network access even when the user fails to authenticate. The switch logs the results of the authentication process for diagnostic purposes. The main purpose of this mode is to help troubleshoot the configuration of a Dot1x authentication on the switch without affecting the network access to the users of the switch.
Page 65: Time-Based Acls
Time-Based ACLs With the Time-based ACL feature, you can define when an ACL is in effect and the amount of time it is in effect. For information about configuring time-based ACLs, see "Configuring Access Control Lists" on page 523. IP Source Guard (IPSG) IP source guard (IPSG) is a security feature that filters IP packets based on the source ID.

Cell Buffer Pool (CBP) memory. AFS, which is also known as cut-through mode, is configurable through the command-line interface. For information about how to configure the AFS CLI Reference Guide feature, see the available at support.dell.com/manuals. Switch Features...
Page 67: Jumbo Frames Support
PAUSE frame indicating that the transmitter should cease transmission of frames for a specified period. When flow control is enabled, the PowerConnect M6220, M6348, M8024, and M8024-k switches will observe received PAUSE frames or jamming signals, but will not issue them when congested.
Page 68: Auto Negotiation
PowerConnect M6220, M6348, M8024, and M8024-k switches enhance auto negotiation by providing configuration of port advertisement. Port advertisement allows the system administrator to configure the port speeds that are advertised.
Page 69: Static And Dynamic Mac Address Tables
Static and Dynamic MAC Address Tables You can add static entries to the switch’s MAC address table and configure the aging time for entries in the dynamic MAC address table. You can also search for entries in the dynamic table based on several different criteria. For information about viewing and managing the MAC address table, see "Managing the MAC Address Table"...
Page 70: Priority-Based Flow Control (Pfc)
Priority-based Flow Control (PFC) NOTE: PFC is supported only on the PCM8024-k. The PCM6220, PCM6348, and PCM8024 switches do not support PFC. The Priority-based Flow Control feature allows the switch to pause or inhibit transmission of individual priorities within a single physical link. By configuring PFC to pause a congested priority (priorities) independently, protocols that are highly loss sensitive can share the same link with traffic that has different loss tolerances.
Page 71: Cisco Protocol Filtering
VLAN tag or a combination of the ingress port and packet contents. Packets sharing common attributes can be groups in the same VLAN. The PowerConnect M6220, M6348, M8024, and M8024-k switches are in full compliance with IEEE 802.1Q VLAN tagging.
Page 72: Port-Based Vlans
Port-Based VLANs Port-based VLANs classify incoming packets to VLANs based on their ingress port. When a port uses 802.1X port authentication, packets can be assigned to a VLAN based on the result of the 802.1X authentication a client uses when it accesses the switch. This feature is useful for assigning traffic to Guest VLANs or Voice VLANs.
Page 73: Guest Vlan
Guest VLAN The Guest VLAN feature allows a switch to provide a distinguished service to unauthenticated users. This feature provides a mechanism to allow visitors and contractors to have network access to reach external network with no ability to browse information on the internal LAN. For information about configuring the Guest VLAN see "Configuring Port and System Security"...
Page 74: Spanning Tree Protocol Features
Spanning Tree Protocol Features For information about configuring Spanning Tree Protocol features, see "Configuring the Spanning Tree Protocol" on page 629. Spanning Tree Protocol (STP) Spanning Tree Protocol (IEEE 802.1D) is a standard requirement of Layer 2 switches that allows bridges to automatically prevent and resolve L2 forwarding loops.
Page 75: Bridge Protocol Data Unit (Bpdu) Guard
Bridge Protocol Data Unit (BPDU) Guard Spanning Tree BPDU Guard is used to disable the port in case a new device tries to enter the already existing topology of STP. Thus devices, which were originally not a part of STP, are not allowed to influence the STP topology. BPDU Filtering When spanning tree is disabled on a port, the BPDU Filtering feature allows BPDU packets received on that port to be dropped.
Page 76 achievable between a given pair of systems. LACP automatically determines, configures, binds, and monitors the binding of ports to aggregators within the system. Switch Features...
Page 77: Routing Features
For information about managing the ARP table, see "Configuring IP Routing" on page 907. VLAN Routing PowerConnect M6220, M6348, M8024, and M8024-k switches support VLAN routing. You can also configure the software to allow traffic on a VLAN to be treated as if the VLAN were a router port.
Page 78: Bootp/Dhcp Relay Agent
BOOTP/DHCP Relay Agent The switch BootP/DHCP Relay Agent feature relays BootP and DHCP messages between DHCP clients and DHCP servers that are located in different IP subnets. For information about configuring the BootP/DHCP Relay agent, see "Configuring L2 and L3 Relay Features" on page 931. IP Helper and UDP Relay The IP Helper and UDP Relay features provide the ability to relay various protocols to servers on a different subnet.
Page 79: Virtual Router Redundancy Protocol (Vrrp)
For information about configuring VRRP settings, see "Configuring VRRP" on page 1057. Tunnel and Loopback Interfaces PowerConnect M6220, M6348, M8024, and M8024-k switches support the creation, deletion, and management of tunnel and loopback interfaces. Tunnel interfaces facilitate the transition of IPv4 networks to IPv6 networks.
Page 80: Ipv6 Routes
IPv6 Routes Because IPv4 and IPv6 can coexist on a network, the router on such a network needs to forward both traffic types. Given this coexistence, each switch maintains a separate routing table for IPv6 routes. The switch can forward IPv4 and IPv6 traffic over the same set of interfaces.
Page 81: Quality Of Service (Qos) Features
The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors. PowerConnect M6220, M6348, M8024, and M8024-k switches support both IPv4 and IPv6 packet classification. For information about configuring DiffServ, see "Configuring Differentiated Services"...
Page 82: Internet Small Computer System Interface (Iscsi) Optimization
Internet Small Computer System Interface (iSCSI) Optimization NOTE: iSCSI is supported on the PCM6348, PCM8024, and PCM8024-k switches. The M6220 switch does not support iSCSI. The iSCSI Optimization feature helps network administrators track iSCSI traffic between iSCSI initiator and target systems. This is accomplished by monitoring, or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI sessions and connections.
Page 83: Igmp Snooping Querier
IPv6 multicast control packets. Multicast VLAN Registration NOTE: MVR is not supported on the PowerConnect M6220. The Multicast VLAN Registration (MVR) protocol, like IGMP Snooping, allows a Layer 2 switch to listen to IGMP frames and forward the multicast traffic only to the receivers that request it.
Page 84: Layer 3 Multicast Features
The Internet Group Management Protocol (IGMP) is used by IPv4 systems (hosts and routers) to report their IP multicast group memberships to any neighboring multicast routers. PowerConnect M6220, M6348, M8024, and M8024-k switches perform the “multicast router part” of the IGMP protocol, which means it collects the membership information needed by the active multicast router.
Page 85: Protocol Independent Multicast-Sparse Mode
Protocol Independent Multicast—Sparse Mode Protocol Independent Multicast-Sparse Mode (PIM-SM) is used to efficiently route multicast traffic to multicast groups that may span wide area networks, and where bandwidth is a constraint. PIM-SM uses shared trees by default and implements source-based trees for efficiency. This data threshold rate is used to toggle between trees.

Why Is Basic Network Information Needed? PowerConnect M6220, M6348, M8024, and M8024-k switches are layer 2/3 managed switches. To manage the switch remotely by using a web browser or Telnet client, the switch must have an IP address, subnet mask, and default gateway.
Page 125: How Is Basic Network Information Configured
You must use a console-port connection to perform the initial switch configuration. When you boot the switch for the first time and the configuration file is empty, the Dell Easy Setup Wizard starts. The Dell Easy Setup Wizard is a CLI-based tool to help you perform the initial switch configuration.
Page 126 Dell recommends that you use the OOB port for remote management. The following list highlights some advantages of using OOB management instead of in-band management: •...
Page 127: Default Network Information
Adjusting the Management Interface MTU When logging in to the PowerConnect switch using TCP, the switch negotiates the TCP Maximum Segment Size (MSS) using the minimum of the requested MSS or the MTU setting of the port. TCP packets are transmitted from the switch with the DF (Don't Fragment) bit set in order to receive notification of fragmentation from any transit routers.

Page 143: Managing A Switch Stack
Managing a Switch Stack This chapter describes how to configure and manage a stack of switches. NOTE: Stacking is supported on the PowerConnect M6220, PowerConnect M6348, and PowerConnect M8024-k switches. PowerConnect M8024 switches do not support stacking. The topics covered in this chapter include: •...
Page 144 NOTE: Each PowerConnect M6220 switch in the stack must have the optional Stacking module installed in Bay 1. NOTE: PowerConnect M6348, M6220, and M8024-k switches cannot be stacked together. A stack is created by daisy-chaining stacking links on adjacent units. Up to eight links per stack unit can be used for stacking (four in each direction).
Page 145: Creating A Powerconnect M6220 Stack
Creating a PowerConnect M6220 Stack You can stack up to 12 PowerConnect M6220 units, supporting up to 240 1-Gb ports. PCM6220 switches can be stacked only with other PCM6220 switches. Create a stack by connecting adjacent units using the stacking ports on the top of the switch panel.
Page 146: Creating A Powerconnect M6348 Stack
Stacking Cables The stack in Figure 8-1 has six M6220 switches connected through the stacking ports. The first stacking port on each switch is physically connected to the second stacking port on the next switch by using a stacking cable. The first stacking port on switch six is connected to the second stacking port on switch one.
Page 147: Creating A Powerconnect M8024-K Stack
1 For each switch in the stack, connect one of the short stacking cables from stacking port one on the switch to stacking port two on the next switch. 2 If necessary, use a separately purchased, long (3 meter) stacking cable to connect the switches.
Page 148 1 If you are using the 10G SFP+ ports for stacking, use the CLI or web interface to configure the ports for stacking. By default, the ports are configured to operate in Ethernet mode. For more information about configuring the port mode, see "Stack Port Summary" on page 163 (Web) or "Configuring Stack Member, Stack Port, and NSF Settings"...
Page 149: Powerconnect 7000 Series And M6348 Stacking Compatibility
Figure 8-3. Connecting a Stack of PowerConnect M8024-k Switches SFP+ Ports Configured as Stack Ports Fiber Optic Cables Connect the Stack PowerConnect 7000 Series and M6348 Stacking Compatibility The stack can contain any combination of switch models in the PowerConnect 7000 Series as well as the PowerConnect M6348 switch, as long as all switches are running the same firmware version.
Page 150: How Is The Stack Master Selected
How is the Stack Master Selected? A stack master is elected or re-elected based on the following considerations, in order: 1 The switch is currently the stack master. 2 The switch has the higher MAC address. 3 A unit is selected as standby by the administrator, and a fail over action is manually initiated or occurs due to stack master failure.
Page 151: Adding A Switch To The Stack
• If the unit number is configured and there are no other devices using the unit number, then the switch starts using the configured unit number. • If the switch detects that the maximum number of units already exist in the stack making it unable to assign a unit number, then the switch sets its unassigned and does not participate in the stack.
Page 152: Removing A Switch From The Stack
Removing a Switch from the Stack Prior to removing a member from a stack, check that other members of the stack will not become isolated from the stack due to the removal. Check the stack-port error counters to ensure that a stack configured in a ring topology can establish a communication path around the member to be removed.
Page 153: What Is Stacking Standby
What is Stacking Standby? A standby unit is preconfigured in the stack. If the current stack master fails, the standby unit becomes the stack master. If no switch is pre-configured as the standby unit, the software automatically selects a standby unit from the existing stack units.
Page 154 1 A protocol can distribute a part of its control plane to stack units so that the protocol can give the appearance that it is still functional during the restart. 2 A protocol may enlist the cooperation of its neighbors through a technique known as graceful restart.
Page 155 The NSF checkpoint service allows the stack master to communicate certain data to the backup unit in the stack. When the stack selects a backup unit, the checkpoint service notifies applications to start a complete checkpoint. After the initial checkpoint is done, applications checkpoint changes to their data.

Page 174: Nsf In The Data Center
NSF in the Data Center Figure 8-14 illustrates a data center scenario, where the stack of two PowerConnect switches acts as an access switch. The access switch is connected to two aggregation switches, AS1 and AS2. The stack has a link from two different units to each aggregation switch, with each pair of links grouped together in a LAG.
Page 175: Nsf And Voip
NSF and VoIP Figure 8-15 shows how NSF maintains existing voice calls during a stack master failure. Assume the top unit is the stack master. When the stack master fails, the call from phone A is immediately disconnected. The call from phone B continues.
Page 176: Nsf And Dhcp Snooping
NSF and DHCP Snooping Figure 8-16 illustrates an L2 access switch running DHCP snooping. DHCP trusted snooping only accepts DHCP server messages on ports configured as ports. DHCP snooping listens to DHCP messages to build a bindings database that lists the IP address the DHCP server has assigned to each host. IP Source Guard (IPSG) uses the bindings database to filter data traffic in hardware based on source IP address and source MAC address.
Page 177: Nsf And The Storage Access Network
If a host is in the middle of an exchange with the DHCP server when the failover occurs, the exchange is interrupted while the control plane restarts. When DHCP snooping is enabled, the hardware traps all DHCP packets to the CPU. The control plane drops these packets during the restart. The DHCP client and server retransmit their DHCP messages until the control plane has resumed operation and messages get through.
Page 178 Figure 8-17. NSF and a Storage Area Network When the stack master fails, session A drops. The initiator at 10.1.1.10 detects a link down on its primary NIC and attempts to reestablish the session on its backup NIC to a different IP address on the disk array. The hardware forwards the packets to establish this new session, but assuming the session is established before the control plane is restarted on the backup unit, the new session receives no priority treatment in the hardware.
Page 179: Nsf And Routed Access
NSF and Routed Access Figure 8-18 shows a stack of three units serving as an access router for a set of hosts. Two LAGs connect the stack to two aggregation routers. Each LAG is a member of a VLAN routing interface. The stack has OSPF and PIM adjacencies with each of the aggregation routers.
Page 180 JOIN messages upstream. The control plane updates the driver with checkpointed unicast routes. The forwarding plane reconciles L3 hardware tables. The OSPF graceful restart finishes, and the control plane deletes any stale unicast routes not relearned at this point. The forwarding plane reconciles L3 multicast hardware tables.
Page 181: Configuring Authentication
Configuring Authentication, Authorization, and Accounting This chapter describes how to control access to the switch management interface using authentication and authorization. It also describes how to record this access using accounting. Together the three services are referred to by the acronym AAA. The topics covered in this chapter include: •...
Page 182: Methods
Each service is configured using method lists. The method lists define how each service is to be performed by specifying the methods available to perform a service. The first method in a list is tried first. If the first method returns an error, the next method in the list is tried.
Page 183: Access Lines
The ias method is a special method that is only used for 802.1X. It uses an • internal database (separate from the local user database) that acts like an 802.1X authentication server. This method never returns an error. It will always pass or deny a user.
Page 184: Authorization
Login— Login authentication grants access to the switch if the user • credentials are validated. Access is granted only at privilege level one. • Enable—Enable authentication grants access to a higher privilege level if the user credentials are validated for the higher privilege level. When RADIUS is used for enable authentication, the username for this request is always $enab15$.
Page 185: Exec Authorization Capabilities
Network: Network authorization enables a RADIUS server to assign a • particular 802.1X supplicant to a VLAN. For more information about 802.1X, see "Configuring Port and System Security" on page 481. Table 9-3 shows the valid methods for each type of authorization: Table 9-3.

Table 9-4. Accounting Methods Method Commands Dot1x Exec radius tacacs Authentication Examples It is important to understand that during authentication, all that happens is that the user is validated. If any attributes are returned from the server, they are not processed during authentication. In the examples below, it is assumed that the default configuration of authorization—that is, no authorization—is used.

Page 191: Authorization Examples
Authorization Examples Authorization allows the administrator to control which services a user is allowed to access. Some of the things that can be controlled with authorization include the user's initial privilege level and which commands the user is allowed to execute. When authorization fails, the user is denied access to the switch, even though the user has passed authentication.

Page 196: Using Radius Servers To Control Management Access
The RADIUS server should be configured such that it will send the Cisco AV Pair attribute with the “roles” value. For example: shell:roles=router-admin The above example attribute gives the user access to the commands permitted by the router-admin profile. Using RADIUS Servers to Control Management Access The RADIUS client on the switch supports multiple RADIUS servers.
Page 197 “secret”. This “secret” is used to generate one-way encrypted authenticators that are present in all RADIUS packets. The “secret” is never transmitted over the network. RADIUS conforms to a secure communications client/server model using UDP as a transport protocol. It is extremely flexible, supporting a variety of methods to authenticate and statistically track users.
Page 198: Which Radius Attributes Does The Switch Support
If you use a RADIUS server to authenticate users, you must configure user attributes in the user database on the RADIUS server. The user attributes include the user name, password, and privilege level. NOTE: To set the privilege level, it is recommended to use the Service-Type attribute instead of the Cisco AV pair priv-lvl attribute.

Page 201: Using Tacacs+ Servers To Control Management Access
Using TACACS+ Servers to Control Management Access TACACS+ (Terminal Access Controller Access Control System) provides access control for networked devices via one or more centralized servers. TACACS+ simplifies authentication by making use of a single database that can be shared by many clients on a large network. TACACS+ uses TCP to ensure reliable delivery and a shared key configured on the client and daemon server to encrypt all messages.
Page 202: Which Tacacs+ Attributes Does The Switch Support
You can configure each server host with a specific connection type, port, timeout, and shared key, or you can use global configuration for the key and timeout. The TACACS+ server can do the authentication itself, or redirect the request to another back-end device.

Page 208: Why Is System Information Needed
Why Is System Information Needed? The information the switch provides can help you troubleshoot issues that might be affecting system performance. The cable diagnostics test help you troubleshoot problems with the physical connections to the switch. Auditing access to the switch and the activities an administrator performed while managing the switch can help provide security and accountability.
Page 209: What Are The Severity Levels
What Are the Severity Levels? For each local or remote log file, you can specify the severity of the messages to log. Each severity level is identified by a name and a number. Table 10-1 provides information about the severity levels. Table 10-1.
Page 210: What Is The Log Message Format
The first part of the log message up to the first left bracket is fixed by the Syslog standard (RFC 3164). The second part up to the two percent signs is standardized for all Dell PowerConnect logs. The variable text of the log message follows. The log message is limited to 96 bytes.
Page 211: What Factors Should Be Considered When Configuring Logging
Message — Contains the text of the log message. What Factors Should Be Considered When Configuring Logging? Dell recommends that network administrators deploy a syslog server in their network and configure all switches to log messages to the syslog server. Switch administrators should also consider enabling persistent logging on the switch.
Page 212 After you enable email alerting and configure the mail server and recipient email address, log messages with a severity level of emergency and alert are sent immediately with each log message in a separate mail. The email subject is “Urgent Log Messages.” Log messages with a severity level of critical, error, and warning are sent periodically in a single email.

Page 243: Managing General System Settings
Managing General System Settings This chapter describes how to set system information, such as the hostname, and time settings, and how to select the Switch Database Management (SDM) template to use on the switch. This chapter also describes how to view expansion slot information as well as how to configure the operational mode and Port Aggregator feature.
Page 244: Why Does System Information Need To Be Configured
Configuring system information is optional. However, it can be helpful in providing administrative information about the switch. For example, if you manage several standalone PowerConnect M6220, M6348, M8024, and M8024-k switches and have Telnet sessions open with several different switches, the system name can help you quickly identify the switch because the host name replaces console as the CLI command prompt.
Page 245: What Is Simple Mode
Simple mode. NOTE: The PowerConnect M8024-k switch operates in Simple mode by default. The PowerConnect M6220, M6348, and M8024 switches operate in normal mode, with Simple mode disabled, by default. When Simple mode is enabled, negotiation, speed, duplex, VLAN, and MTU configurations are allowed on the Aggregator Group but not on the individual ports.
Page 246 • Simple mode allows the user to create Aggregation Groups where internal ports and external ports can be configured in a separate broadcast domain. • Security-related configurations: dot1x, RADIUS, TACACS+ are allowed when the switch is operating in Simple Mode. •...

After the process completes, the Auto Configuration process writes a log message. When Auto Configuration has successfully completed, you can execute a show running-config command to validate the contents of configuration.
Page 363: What Are The Dependencies For Dhcp Auto Configuration
What Are the Dependencies for DHCP Auto Configuration? The Auto Configuration process from TFTP servers depends upon the following network services: • A DHCP server must be configured on the network with appropriate services. • An image file and a text file containing the image file name for the switch must be available from a TFTP server if DHCP image download is desired.
Page 364: Default Auto Configuration Values

Page 369: Monitoring Switch Traffic
The switch maintains statistics about network traffic that it handles. It also has embedded technology that collects and sends information about traffic to other devices. PowerConnect M6220, M6348, M8024, and M8024-k switches include support for flow-based monitoring through sFlow and Remote Network Monitoring (RMON) agents.
Page 370 sampled traffic statistics to the sFlow Collector for analysis. You can specify up to eight different sFlow receivers to which the switch sends sFlow datagrams. Figure 15-1. sFlow Architecture The advantages of using sFlow are: • It is possible to monitor all ports of the switch continuously, with no impact on the distributed switching performance.
Page 371 sFlow Sampling The sFlow Agent in the PowerConnect software uses two forms of sampling: • Statistical packet-based sampling of switched or routed Packet Flows • Time-based sampling of counters Packet Flow Sampling and Counter Sampling are performed by sFlow Instances associated with individual Data Sources within an sFlow Agent. Both types of samples are combined in sFlow datagrams.
Page 372: What Is Rmon
Like sFlow, RMON is a technology that enables the collection and analysis of a variety of data about network traffic. PowerConnect M6220/M6348/M8024/M8024-k switch software includes an RMON probe (also known as an RMON agent) that collect information and analyze packets. The data that is collected is defined in the RMON MIB, RFC 2819.
Page 373: What Is Port Mirroring
A port monitoring session includes one or more source ports that mirror traffic to a single destination port. The PowerConnect M6220, M6348, M8024, and M8024-k switches support a single port monitoring session.
Page 374: Why Is Traffic Monitoring Needed
The packet that is copied to the destination port is in the same format as the original packet on the wire. This means that if the mirror is copying a received packet, the copied packet is VLAN tagged or untagged as it was received on the source port.

Page 410: What Does Iscsi Optimization Do
What Does iSCSI Optimization Do? In networks containing iSCSI initiators and targets, iSCSI Optimization helps to monitor iSCSI sessions or give iSCSI traffic preferential QoS treatment. Dynamically-generated classifier rules generated by snooping iSCSI traffic are used to direct iSCSI data traffic to queues that can be given the desired preference characteristics over other data traveling through the switch.
Page 411: How Does Iscsi Optimization Use Acls
Application Priority TLVs received from the configuration source are proxied to the other ports. When iSCSI CoS mode is enabled, iSCSI login sessions up to the switch limits are tracked, and data packets for those sessions are given the configured CoS treatment.
Page 412 • Initiator's IP Address • Target's IP Address • ISID (Initiator defined session identifier) • Initiator's IQN (iSCSI Qualified Name) • Target's IQN • Initiator's TCP Port • Target's TCP Port If no iSCSI traffic is detected for a session for a configurable aging period, the session data is cleared.

The PowerConnect M6220, M6348, M8024, and M8024-k switches use LLDP , a vendor-neutral protocol, to discover Dell EQL devices on the network. LLDP is enabled by default. For more information about LLDP, see "Discovering Network Devices"...
Page 414: How Does Iscsi Optimization Interact With Dcbx
How Does iSCSI Optimization Interact with Dell Compellent Arrays? Dell PowerConnect switches support a macro that may be used to configure a port connected to a Dell Compellent storage array. The name of the macro is profile-compellent-nas. The macro takes a single argument: the interface identifier to which the Dell Compellent array is connected.
Page 415: Iscsi Cos And Priority Flow Control/Enhanced Transmission Selection Interactions
iSCSI CoS and Priority Flow Control/Enhanced Transmission Selection Interactions When manually or automatically enabling the classification of iSCSI flows on PC80xx/PCM8024-k/PC81xx series switches, enabling iSCSI CoS is not recommended. When using manual configuration of the switch or auto-configuration via DCBX, the iSCSI packets are classified based on the user priority present in the VLAN tag and, in this case, enabling iSCSI CoS classification via the iSCSI command set provides no benefit.

Page 427: What Factors Should Be Considered When Designing And Configuring A Captive Portal
Captive Portal? Before enabling the Captive Portal feature, decide what type (or types) of authentication to require. Since the PowerConnect M6220, M6348, M8024, and M8024-k switches support up to 10 different Captive Portal instances, you can configure one Captive Portal that requires a username and password and another that only requires the username.

Page 463: Configuring Port Characteristics
Port Configuration Examples Port Overview A port is a physical interface. The PowerConnect M6220, M6348, M8024, and M8024-k switches support both external and internal ports. The external ports connect devices such as PCs or servers to the switch by using cables.
Page 464: What Is Link Dependency
Table 18-1. Port Characteristics (Continued) Feature Description Auto negotiation Enables a port to advertise its transmission rate, duplex mode and flow control abilities to its partner. Speed Specifies the transmission rate for frames. Duplex mode Specifies whether the interface supports transmission between the switch and the connected client in one direction at a time (half) or both directions simultaneously (both).
Page 465 You can create a maximum of 72 dependency groups for stacking switches or 16 groups for a standalone switch. The ports participating in the Link Dependency can be across all the Stack Units (Manager/Member unit). Link Action The link action specifies the action that the group members will take when the dependent port is down.

Page 481: Configuring Port And System
Configuring Port and System Security This chapter describes how to configure port-based security features, which control access to the network through the switch ports, and the denial of service (DoS) feature. Port-based security includes IEEE 802.1X authentication and port MAC locking.
Page 482: Ieee 802.1X
IEEE 802.1X What is IEEE 802.1X? The IEEE 802.1X standard provides a means of preventing unauthorized access by supplicants (clients) to the services the switch offers, such as access to the LAN. The 802.1X network has three components: • Supplicant — The client connected to the authenticated port that requests access to the network.
Page 483: What Are The 802.1X Port States
As shown in Figure 19-1, the PowerConnect M6220/M6348/M8024/M8024-k switch is the authenticator and enforces the supplicant (a PC) that is attached to an 802.1X-controlled port to be authenticated by an authentication server (a RADIUS server). The result of the authentication process determines whether the supplicant is authorized to access services on that controlled port.
Page 484: What Is Mac-Based 802.1X Authentication
What is MAC-Based 802.1X Authentication? MAC-based authentication allows multiple supplicants connected to the same port to each authenticate individually. For example, a 5-port hub might be connected to a single port on the switch. Each host connected to the hub must authenticate separately in order to gain access to the network.
Page 485: What Is The Role Of 802.1X In Vlan Assignment
What is the Role of 802.1X in VLAN Assignment? PowerConnect M6220, M6348, M8024, and M8024-k switches allow a port to be placed into a particular VLAN based on the result of the authentication or type of 802.1X authentication a client uses when it accesses the switch. The authentication server can provide information to the switch about which VLAN to assign the supplicant.
Page 486 The VLAN attributes defined in RFC3580 are as follows: • Tunnel-Type=VLAN (13) • Tunnel-Medium-Type=802 • Tunnel-Private-Group-ID=VLANID VLANID is 12-bits and has a value between 1 and 4093. Dynamic VLAN Creation If RADIUS-assigned VLANs are enabled though the Authorization Network RADIUS configuration option, the RADIUS server is expected to include the VLAN ID in the 802.1X tunnel attributes of its response message to the switch.
Page 487: What Is Monitor Mode
Client devices that are 802.1X-supplicant-enabled authenticate with the switch when they are plugged into the 802.1X-enabled switch port. The switch verifies the credentials of the client by communicating with an authentication server. If the credentials are verified, the authentication server unblock informs the switch to the switch port and allows the client...

How Does the Authentication Server Assign DiffServ Filters? The PowerConnect M6220, M6348, M8024, and M8024-k switches allow the external 802.1X Authenticator or RADIUS server to assign DiffServ policies to users that authenticate to the switch. When a host (supplicant) attempts to connect to the network through a port, the switch contacts the 802.1X...

Page 510 NOTE: Dynamic VLAN creation applies only to authorized ports. The VLANs for unauthorized and guest users must be configured on the switch and cannot be dynamically created based on RADIUS-based VLAN assignment. The commands in this example show how to configure the switch to control VLAN assignment for the example network.
Page 511 To configure the switch: 1 Create the VLANs and configure the VLAN names. console(config)#vlan 100 console(config-vlan100)#name Authorized console(config-vlan100)#exit console(config)#vlan 200 console(config-vlan200)#name Unauthorized console(config-vlan200)#exit console(config)#vlan 300 console(config-vlan300)#name Guest console(config-vlan300)#exit 2 Configure information about the external RADIUS server the switch uses to authenticate clients. The RADIUS server IP address is 10.10.10.10, and the shared secret is qwerty123.
Page 512 8 Enable periodic reauthentication of the client on the ports and set the number of seconds to wait between reauthentication attempts to 300 seconds. Reauthentication is enabled to increase security. If the client information is removed from the RADIUS server after it has been authenticated, the client will be denied access when it attempts to reauthenticate.
Page 513 Allowing Dynamic VLAN Creation of RADIUS-Assigned VLANs The network in this example uses a RADIUS server to provide VLAN assignments to host that connect to the switch. In this example, the VLANs are not configured on the switch. Instead, the switch is configured to allow the dynamic creation of VLANs when a RADIUS-assigned VLAN does not already exist on the switch.
Page 514 5 Allow the switch to dynamically create VLANs when a RADIUS-assigned VLAN does not exist on the switch. console(config)#dot1x dynamic-vlan enable 6 Enter interface configuration mode for the downlink ports. console(config)#interface range gi1/0/1-23 7 Set the downlink ports to the access mode because each downlink port connects to a single host that belongs to a single VLAN.

Page 518: Port Security (Port-Mac Locking)
Port Security (Port-MAC Locking) The Port Security feature allows you to limit the number of source MAC addresses that can be learned on a port. If a port reaches the configured limit, any other addresses beyond that limit are not learned and the frames are discarded.

(for example, Telnet or HTTP) and/or the source IP address. The PowerConnect M6220, M6348, M8024, and M8024-k switches support ACL configuration in both the ingress and egress direction. Egress ACLs provide the capability to implement security rules on the egress flows (traffic leaving a port) rather than the ingress flows (traffic entering a port).
Page 524: What Are Mac Acls
You can set up ACLs to control traffic at Layer 2, Layer 3, or Layer 4. MAC ACLs operate on Layer 2. IP ACLs operate on Layers 3 and 4. PowerConnect M6220, M6348, M8024, and M8024-k switches support both IPv4 and IPv6 ACLs.
Page 525: What Are Ip Acls
What Are IP ACLs? IP ACLs classify for Layers 3 and 4 on IPv4 or IPv6 traffic. Each ACL is a set of up to ten rules applied to inbound traffic. Each rule specifies whether the contents of a given field should be used to permit or deny access to the network, and may apply to one or more of the following fields within a packet: •...
Page 526: What Is Acl Logging
Using ACLs to mirror traffic is considered to be flow-based mirroring since the traffic flow is defined by the ACL classification rules. This is in contrast to port mirroring, where all traffic encountered on a specific interface is replicated on another interface. What Is ACL Logging ACL Logging provides a means for counting the number of “hits”...
Page 527: What Are The Acl Limitations
You can configure mirror or redirect attributes for a given ACL rule, but not both. • The PowerConnect M6220, M6348, M8024, and M8024-k switches support a limited number of counter resources, so it may not be possible to log every ACL rule. You can define an ACL with any number of logging rules, but the number of rules that are actually logged cannot be determined until the ACL is applied to an interface.
Page 528: How Are Acls Configured
NOTE: The actual number of ACLs and rules supported depends on the resources consumed by other processes and configured features running on the switch. How Are ACLs Configured? To configure ACLs, follow these steps: 1 Create a MAC ACL by specifying a name. 2 Create an IP ACL by specifying a number.

Page 561: Configuring Vlans
VLAN Overview By default, all switchports on a PowerConnect M6220/M6348/M8024/M8024-k switch are in the same broadcast domain. This means when one host connected to the switch broadcasts traffic, every device connected to the switch receives that broadcast. All ports in a broadcast domain also forward multicast and unknown unicast traffic to the connected host.
Page 562 Are VLAN Routing Interfaces?" on page 867. Each VLAN has a unique number, called the VLAN ID. The PowerConnect M6220, M6348, M8024, and M8024-k switches support a configurable VLAN ID range of 2–4093. A VLAN with VLAN ID 1 is configured on the switch by default default.
Page 563 VLAN configured for the port. The VLAN membership for this network is port-based or static. PowerConnect M6220, M6348, M8024, and M8024-k switches also support VLAN assignment based on any of the following criteria: •...
Page 564: Switchport Modes
Switchport Modes You can configure each port on a PowerConnect M6220/M6348/M8024/M8024-k switch to be in one of the following modes: • Access — Access ports are intended to connect end-stations to the system, especially when the end-stations are incapable of generating VLAN tags.
Page 565: Vlan Tagging
VLAN Tagging PowerConnect M6220, M6348, M8024, and M8024-k switches support IEEE 802.1Q tagging. Ethernet frames on a tagged VLAN have a 4-byte VLAN tag in the header. VLAN tagging is required when a VLAN spans multiple switches, which is why trunk ports transmit and receive only tagged frames.
Page 566: Gvrp
Double-VLAN Tagging For trunk ports, which are ports that connect one switch to another switch, the PowerConnect M6220, M6348, M8024, and M8024-k switches support double-VLAN tagging. This feature allows service providers to create Virtual Metropolitan Area Networks (VMANs). With double-VLAN tagging, service providers can pass VLAN traffic from one customer domain to another through a metro core in a simple and cost-effective manner.
Page 567 additional tag on the traffic, the switch can differentiate between customers in the MAN while preserving an individual customer’s VLAN identification when the traffic enters the customer’s 802.1Q domain. With the introduction of this second tag, customers are no longer required to divide the 4-byte VLAN ID space to send traffic on a Ethernet-based MAN.
Page 568: Voice Vlan
Figure 21-2. Double VLAN Tagging Network Example Voice VLAN The Voice VLAN feature enables switch ports to carry voice traffic with defined priority. When multiple devices, such as a PC and an IP phone, are connected to the same port, you can configure the port to use one VLAN for voice traffic and another VLAN for data traffic.
Page 569 Identifying Voice Traffic Some VoIP phones contain full support for IEEE 802.1X. When these phones are connected to a port that uses 802.1X port-based authentication, these phones authenticate and receive their VLAN information from LLDP-MED. However, if a VoIP phone has limited support for 802.1X authentication it might try to authenticate and fail.
Page 570: Private Vlans
default PVID of the port, and the voice traffic is received tagged with the predefined VLAN. As a result, both kinds of traffic are segregated in order to provide better service to the voice traffic. • When a dot1p priority is associated with the Voice VLAN port instead of a VLAN ID, then the priority information is passed onto the VoIP phone using the LLDP-MED or CDP mechanism.
Page 571 Isolated VLAN—A secondary VLAN. It carries traffic from isolated ports • to promiscuous ports. Only one isolated VLAN can be configured per private VLAN. Community VLAN—A secondary VLAN. It forwards traffic between ports • which belong to the same community and to the promiscuous ports. There can be multiple community VLANs per private VLAN.
Page 572 Figure 21-3 shows an example Private VLAN scenario, in which five hosts (H- A through H-E) are connected to a stack of switches (SW1, SW2). The switch stack is connected to router R1. Port references shown are with reference to the stack. Figure 21-3.
Page 573 Isolated Ports An endpoint connected to an isolated port is allowed to communicate with endpoints connected to promiscuous ports only. Endpoints connected to adjacent isolated ports cannot communicate with each other. Community Ports An endpoint connected to a community port is allowed to communicate with the endpoints within a community and can also communicate with any configured promiscuous port.

Page 575 Limitations and Recommendations • Only a single isolated VLAN can be associated with a primary VLAN. Multiple community VLANs can be associated with a primary VLAN. • Trunk and general modes are not supported on private VLAN ports. • Do not configure access ports using the VLANs participating in any of the private VLANs.
Page 576: Additional Vlan Features
Private VLAN Configuration Example See "Configuring a Private VLAN" on page 626. Additional VLAN Features The PowerConnect M6220, M6348, M8024, and M8024-k switches also support the following VLANs and VLAN-related features: • VLAN routing interfaces — See "Configuring Routing Interfaces" on page 867.
Page 577: Default Vlan Behavior
Default VLAN Behavior One VLAN is configured on the PowerConnect M6220, M6348, M8024, and M8024-k switches by default. The VLAN ID is 1, and all ports are included in the VLAN as access ports, which are untagged. This means when a device connects to any port on the switch, the port forwards the packets without inserting a VLAN tag.

Configure the VLANs and Ports on Switch 1 Use the following steps to configure the VLANs and ports on Switch 1. None of the hosts that connect to Switch 1 use the Engineering VLAN (VLAN 100), so it is not necessary to create it on that switch.

Page 629: Configuring The Spanning Tree
STP uses the spanning-tree algorithm to provide a single path between end stations on a network. PowerConnect M6220, M6348, M8024, and M8024-k switches support Classic STP , Multiple STP , and Rapid STP . What Are Classic STP, Multiple STP, and Rapid STP? Classic STP provides a single path between end stations, avoiding and eliminating loops.
Page 630: How Does Stp Work
recognize full-duplex connectivity and ports which are connected to end stations, resulting in rapid transitioning of the port to the Forwarding state and the suppression of Topology Change Notifications. MSTP is compatible to both RSTP and STP . It behaves appropriately to STP and RSTP bridges.
Page 631: How Does Mstp Operate In The Network
How Does MSTP Operate in the Network? In the following diagram of a small 802.1d bridged network, STP is necessary to create an environment with full connectivity and without loops. Figure 22-1. Small Bridged Network Assume that Switch A is elected to be the Root Bridge, and Port 1 on Switch B and Switch C are calculated to be the root ports for those bridges, Port 2 on Switch B and Switch C would be placed into the Blocking state.
Page 632 Figure 22-2 shows the logical single STP network topology. Figure 22-2. Single STP Topology For VLAN 10 this single STP topology is fine and presents no limitations or inefficiencies. On the other hand, VLAN 20's traffic pattern is inefficient. All frames from Switch B will have to traverse a path through Switch A before arriving at Switch C.
Page 633 The logical representation of the MSTP environment for these three switches is shown in Figure 22-3. Figure 22-3. Logical MSTP Environment Configuring the Spanning Tree Protocol...
Page 634 In order for MSTP to correctly establish the different MSTIs as above, some additional changes are required. For example, the configuration would have to be the same on each and every bridge. That means that Switch B would have to add VLAN 10 to its list of supported VLANs (shown in Figure 22-3 with a *).
Page 635: Mstp With Multiple Forwarding Paths
MSTP with Multiple Forwarding Paths Consider the physical topology shown in Figure 22-4. It might be assumed that MSTI 2 and MSTI 3 would follow the most direct path for VLANs 20 and 30. However, using the default path costs, this is not the case. MSTI operates without considering the VLAN membership of the ports.
Page 636: What Are The Optional Stp Features
What are the Optional STP Features? The PowerConnect M6220, M6348, M8024, and M8024-k switches support the following optional STP features: • BPDU flooding • PortFast • BPDU filtering • Root guard • Loop guard • BPDU protection BPDU Flooding The BPDU flooding feature determines the behavior of the switch when it receives a BPDU on a port that is disabled for spanning tree.
Page 637 Root Guard Enabling root guard on a port ensures that the port does not become a root port or a blocked port. When a switch is elected as the root bridge, all ports are designated ports unless two or more ports of the root bridge are connected together.
Page 638 BPDU Protection When the switch is used as an access layer device, most ports function as edge ports that connect to a device such as a desktop computer or file server. The port has a single, direct connection and is configured as an edge port to implement the fast transition to a forwarding state.

Page 687: Configuring Port-Based Traffic
Configuring Port-Based Traffic Control This chapter describes how to configure features that provide traffic control through filtering the type of traffic or limiting the speed or amount of traffic on a per-port basis. The features this section describes includes flow control, storm control, protected ports, and Link Local Protocol Filtering (LLPF), which is also known as Cisco Protocol Filtering.
Page 688: What Is Flow Control
Transmissions are temporarily halted to prevent buffer overflows. Enabling the flow control feature allows PowerConnect M6220, M6348, M8024, and M8024-k switches to process pause frames received from connected devices. PowerConnect switches do not transmit pause frames.
Page 689: What Are Protected Ports
LLPF allows a PowerConnect M6220/M6348/M8024/M8024-k switch to filter out various Cisco proprietary protocol data units (PDUs) and/or ISDP if problems occur with these protocols running on standards-based switches. If certain protocol PDUs cause unexpected results, LLPF can be enabled to prevent those protocol PDUs from being processed by the switch.
Page 690: Default Port-Based Traffic Control Values
Access Control Lists (ACLs) and LLPF can exist on the same interface. However, the ACL rules override the LLPF rules when there is a conflict. Similarly, DiffServ and LLPF can both be enabled on an interface, but DiffServ rules override LLPF rules when there is a conflict. If Industry Standard Discovery Protocol (ISDP) is enabled on an interface, and the LLPF feature on an interface is enabled and configured to drop ISDP PDUs, the ISDP configuration overrides the LLPF configuration, and the...

Port-Based Traffic Control Configuration Example The commands in this example configure storm control, LLPF, and protected port settings for various interfaces on the switch. The storm control configuration in this example sets thresholds on the switch so that if broadcast traffic occupies more than 10% on the bandwidth on any physical port, the interface blocks the broadcast traffic until the measured amount of this traffic drops below the threshold.

Page 703: Configuring L2 Multicast Features
Configuring L2 Multicast Features This chapter describes the layer 2 multicast features on the PowerConnect M6220, M6348, M8024, and M8024-k switches. The features this chapter describes include bridge multicast filtering, Internet Group Management Protocol (IGMP) snooping, Multicast Listener Discovery (MLD) snooping, and Multicast VLAN Registration (MVR).
Page 704: What Are The Multicast Bridging Features
What Are the Multicast Bridging Features? The PowerConnect M6220, M6348, M8024, and M8024-k switches support multicast filtering and multicast flooding. For multicast traffic, the switch uses a database called the Layer 2 Multicast Forwarding Database (MFDB) to make forwarding decisions for packets that arrive with a multicast destination MAC address.
Page 705: What Is Igmp Snooping
This approach works well for broadcast packets that are intended to be seen or processed by all connected nodes. In the case of multicast packets, however, this approach could lead to less efficient use of network bandwidth, particularly when the packet is intended for only a small number of nodes. Packets will be flooded into network segments where no node has any interest in receiving the packet.
Page 706 in scenarios, such as FCoE/FIP snooping, where it is desirable to flood L2 control plane multicast messages that do not utilize well-known multicast addresses. By default, multicast routers are aged out every five minutes. The user can control whether or not multicast routers age out. If all multicast routers age out, the switch floods the VLAN with the multicast group.
Page 707: What Is Mld Snooping
NOTE: Without an IP-multicast router on a VLAN, you must configure another switch as the IGMP querier so that it can send queries. When IGMP snooping querier is enabled, the querier switch sends out periodic IGMP queries that trigger IGMP report messages from the hosts that want to receive IP multicast traffic.
Page 708: What Is Multicast Vlan Registration
permanently assigned (well-known) multicast address FF0x::/12 to all ports in the VLAN, except for MLD packets, which are handled according the MLD snooping rules. NOTE: It is strongly recommended that users enable IGMP snooping if MLD snooping is enabled and vice-versa. This is because both IGMP snooping and MLD snooping utilize the same forwarding table, and not enabling both may cause unwanted pruning of protocol packets utilized by other protocols, e.g.
Page 709: When Are L3 Multicast Features Required
There are two configured learning modes of the MVR operation: dynamic and compatible. • In the dynamic mode MVR learns existent multicast groups by parsing the IGMP queries from router on source ports and forwarding the IGMP joins from the hosts to the router. •...
Page 710: What Are Garp And Gmrp
GARP defines a set of switches interested in a given network attribute, such as VLAN ID or multicast address. PowerConnect M6220, M6348, M8024, and M8024-k switches can use GARP functionality for two applications: •...
Page 711 GMRP is similar to IGMP snooping in its purpose, but IGMP snooping is more widely used. GMRP must be running on both the host and the switch to function properly and IGMP/MLD snooping must be disabled on the switch, as IGMP snooping and GMRP cannot simultaneously operate within the same VLAN.
Page 712: Snooping Switch Restrictions
Snooping Switch Restrictions Partial IGMPv3 and MLDv2 Support The IGMPv3 and MLDv2 protocols allow multicast listeners to specify the list of hosts from which they want to receive the traffic. However the PowerConnect snooping switch does not track this information. IGMPv3/MLDv2 Report messages that have the group record type CHANGE_TO_INCLUDE_MODE with a null source list are treated as Leave messages.
Page 713: Topologies Where The Multicast Source Is Not Directly Connected To The Querier
Topologies Where the Multicast Source Is Not Directly Connected to the Querier If the multicast source is not directly connected to a multicast querier, the multicast stream is forwarded to any router ports on the switch (within the VLAN). Because multicast router queries are flooded to all ports in the VLAN, intermediate IGMP snooping switches will receive the multicast stream from the multicast source and forward it to the multicast router.

802.3ah), where the faults are detected and notified on a single point-to-point IEEE Std. 802.3 LAN, Dot1ag addresses fault diagnosis at the service layer across networks comprising multiple LANs, including LANs other than 802.3 media. How Does Dot1ag Work Across a Carrier Network? A typical metropolitan area network comprises operator, service provider, and customer networks.
Page 763: What Entities Make Up A Maintenance Domain
Entities at different levels have different responsibilities. For example, the lower level (operator) overlooks a subset of the network in detail and provides information about its status to its higher levels such as the provider level). Higher levels have a broader, but less detailed, view of the network. As a result, a provider could include multiple operators, provided that the domains never intersect.
Page 764 • MIPs are entities within a domain that enable the outer domain to achieve end-to-end connectivity checks. MIPs passively receive CFM messages and respond back to the originating MEP. Figure 26-2 depicts two MEPs and the MIPs that connect them in a maintenance domain.
Page 765: What Is The Administrator's Role
Figure 26-3. Provider View for Service Level OAM What is the Administrator’s Role? On the switch, the administrator configures the customer-level maintenance domains, associations, and endpoints used to participate in Dot1ag services with other switches connected through the provider network. The Administrator can also use utilities to troubleshoot connectivity faults when reported via SNMP traps.
Page 766: Default Dot1Ag Values
Troubleshooting Tasks In the event of a connectivity loss between MEPs, the administrator can perform path discovery, similar to traceroute, from one MEP to any MEP or MIP in a maintenance domain using Link Trace Messages (LTMs). The connectivity loss is narrowed down using path discovery and is verified using Loop-back Messages (LBMs), which are similar to ping operations in IP networks.

The topics covered in this chapter include: •...
Page 782: What Is Dhcp Snooping
What Is DHCP Snooping? Dynamic Host Configuration Protocol (DHCP) Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP server to accomplish the following tasks: • Filter harmful DHCP messages • Build a bindings database with entries that consist of the following information: •...
Page 783: How Is The Dhcp Snooping Bindings Database Populated
How Is the DHCP Snooping Bindings Database Populated? The DHCP snooping application uses DHCP messages to build and maintain the binding’s database. DHCP snooping creates a tentative binding from DHCP DISCOVER and REQUEST messages. Tentative bindings tie a client to a port (the port where the DHCP client message was received). Tentative bindings are completed when DHCP snooping learns the client’s IP address from a DHCP ACK message on a trusted port.
Page 784 DHCP Snooping and VLANs DHCP snooping forwards valid DHCP client messages received on non- routing VLANs. The message is forwarded on all trusted interfaces in the VLAN. DHCP snooping can be configured on switching VLANs and routing VLANs. When a DHCP packet is received on a routing VLAN, the DHCP snooping application applies its filtering rules and updates the bindings database.
Page 785: What Is Ip Source Guard
What Is IP Source Guard? IPSG is a security feature that filters IP packets based on source ID. This feature helps protect the network from attacks that use IP address spoofing to compromise or overwhelm the network. The source ID may be either the source IP address or a {source IP address, source MAC address} pair.
Page 786: What Is Dynamic Arp Inspection
What is Dynamic ARP Inspection? Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP packets. DAI prevents a class of man-in-the-middle attacks where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors. The malicious attacker sends ARP requests or responses mapping another station’s IP address to its own MAC address.
Page 787: Why Is Traffic Snooping And Inspection Necessary
Why Is Traffic Snooping and Inspection Necessary? DHCP Snooping, IPSG, and DAI are security features that can help protect the switch and the network against various types of accidental or malicious attacks. It might be a good idea to enable these features on ports that provide network access to hosts that are in physically unsecured locations or if network users connect nonstandard hosts to the network.

LAG as a static member, it neither transmits nor receives LACP PDUs. What is LAG Hashing? PowerConnect M6220, M6348, M8024, and M8024-k switches support configuration of hashing algorithms for each LAG interface. The hashing algorithm is used to distribute traffic load among the physical ports of the LAG while preserving the per-flow packet order.

How Do LAGs Interact with Other Features? From a system perspective, a LAG is treated just as a physical port, with the same configuration parameters for administrative enable/disable, spanning tree port priority, path cost as may be for any other physical port. VLAN When members are added to a LAG, they are removed from all existing VLAN membership.

Page 846: Dcb Capability Exchange
DCB Capability Exchange The Data Center Bridging Exchange Protocol (DCBx) is used by DCB devices to exchange configuration information with directly connected peers. DCBx uses type-length-value (TLV) information elements over LLDP to exchange information, so LLDP must be enabled on the port to enable the information exchange.
Page 847: Interoperability With Ieee Dcbx
DCBX information is carried over LLDP, which is a link-local protocol. When configuring links in a port channel to use DCBX, the DCBX settings should be the same for all links in the port channel. Interoperability with IEEE DCBx To be interoperable with legacy industry implementations of the DCBx protocol, The PowerConnect M8024-k switches use a hybrid model to support both the IEEE version of DCBx (IEEE 802.1Qaz) and legacy DCBx versions.
Page 848 Ports operating in the manual role do not have their configuration affected by peer devices or by internal propagation of configuration. These ports have their operational mode, traffic classes, and bandwidth information specified explicitly by the operator. These ports advertise their configuration to their peer if DCBx is enabled on that port.
Page 849: Configuration Source Port Selection Process
A port operating in the auto-downstream role advertises a configuration but is not willing to accept one from the link partner. However, the port will accept a configuration propagated internally by the configuration source. Specifically, the willing parameter is disabled on auto-downstream. By default, auto- downstream ports have the recommendation TLV parameter enabled.

Page 854: Fip Snooping
FIP Snooping The FCoE Initialization Protocol (FIP) is used to perform the functions of FC_BB_E device discovery, initialization, and maintenance. FIP uses a separate EtherType from FCoE to distinguish discovery, initialization, and maintenance traffic from other FCoE traffic. FIP frames are standard Ethernet size (1518 Byte 802.1q frame), whereas FCoE frames are a maximum of 2240 bytes.
Page 855: Configuring The Fc Map Value
FCF facing interface. Dell recommends that FCF-facing ports be placed into auto-upstream mode in order to receive DCBx information and propagate it to the Converged Network Adaptors (CNAs) on the auto-downstream ports. Interfaces enabled for PFC should be configured in trunk mode and must be PFC operationally enabled before FCoE traffic can pass over the port.
Page 856: Configuring Fip Snooping (Cli)
Configuring FIP Snooping (CLI) Beginning in Privileged EXEC mode, use the following commands to configure FIP snooping. NOTE: FIP snooping will not allow FIP or FCoE frames to be forwarded over a port until the port is operationally enabled for PFC. VLAN tagging must be enabled on the interface in order to carry the dot1p values through the network.

What Information Is in the MAC Address Table? Each entry in the address table, whether it is static or dynamic, includes the MAC address, the VLAN ID associated with the MAC address, and the interface on which the address was learned or configured. Each port can maintain multiple MAC addresses, and a MAC address can be associated with multiple VLANs.

Page 867: Configuring Routing Interfaces
VLANs divide a single physical network (broadcast domain) into separate logical networks. To forward traffic across VLAN boundaries, a layer 3 device, such as router, is required. PowerConnect M6220, M6348, M8024, and M8024-k switches can act as layer 3 devices when you configure VLAN routing interfaces.
Page 868: What Are Loopback Interfaces
traffic between VLANs while still containing broadcast traffic within VLAN boundaries. The configuration of VLAN routing interfaces makes inter-VLAN routing possible. For each VLAN routing interface you can assign a static IP address, or you can allow a network DHCP server to assign a dynamic IP address. When a port is enabled for bridging (L2 switching) rather than routing, which is the default, all normal bridge processing is performed for an inbound packet, which is then associated with a VLAN.
Page 869: What Are Tunnel Interfaces
The packet is in an incompatible addressing space. • The packet is encrypted. PowerConnect M6220, M6348, M8024, and M8024-k switches support tunnels to encapsulate IPv6 traffic in IPv4 tunnels to provide functionality to facilitate the transition of IPv4 networks to IPv6 networks.
Page 870: Why Are Routing Interfaces Needed
Why Are Routing Interfaces Needed? The routing interfaces this chapter describes have very different applications and uses, as this section describes. If you use the switch as a layer 2 device that handles switching only, routing interface configuration is not required. When the switch is used as a layer 2 device, it typically connects to an external layer 3 device that handles the routing functions.
Page 871 Loopback Interfaces When packets are sent to the loopback IP address, the network should be able to deliver the packets as long as any physical interface on the switch is up. There are many cases where you need to send traffic to a switch, such as in switch management.
Page 872: Default Routing Interface Values
Default Routing Interface Values By default, no routing interfaces are configured. When you create a VLAN, no IP address is configured, and DHCP is disabled. After you configure an IP address on a VLAN or loopback interface, routing is automatically enabled on the VLAN interface, and the interface has the default configuration shown in Table 31-1.

Page 933: What Is The Ip Helper Feature
Enabling L2 Relay on VLANs You can enable L2 DHCP relay on a particular VLAN. The VLAN is identified by a service VLAN ID (S-VID), which a service provider uses to identify a customer’s traffic while traversing the provider network to multiple remote sites.

Page 955: Configuring Ospf And Ospfv3
Configuring OSPF and OSPFv3 This chapter describes how to configure Open Shortest Path First (OSPF) and OSPFv3. OSPF is a dynamic routing protocol for IPv4 networks, and OSPFv3 is used to route traffic in IPv6 networks. The protocols are configured separately within the software, but their functionality is largely similar for IPv4 and IPv6 networks.
Page 956: Ospf Overview
OSPF Overview OSPF is an Interior Gateway Protocol (IGP) that performs dynamic routing within a network. PowerConnect M6220, M6348, M8024, and M8024-k switches support two dynamic routing protocols: OSPF and Routing Information Protocol (RIP). Unlike RIP , OSPF is a link-state protocol. Larger networks typically use the OSPF protocol instead of RIP.
Page 957: What Are Ospf Routers And Lsas
What Are OSPF Routers and LSAs? When a PowerConnect switch is configured to use OSPF for dynamic routing, it is considered to be an OSPF router. OSPF routers keep track of the state of the various links they send data to. Routers exchange OSPF link state advertisements (LSAs) with other routers.
Page 958: Ospf Feature Details
OSPF Feature Details This section provides details on the following OSPF features: • Max Metric • Static Area Range Cost • LSA Pacing • LSA Pacing Max Metric RFC 3137 introduced stub router behavior to OSPFv2. As a stub, a router can inform other routers that it is not available to forward data packets.
Page 959 mode. OSPF does not begin in stub router mode when OSPF is globally enabled. If the operator wants to avoid routing transients when he enables or configures OSPF, he can manually set OSPF in stub router mode. If OSPF is in startup stub router mode and encounters a resource limitation that would normally cause OSPF to become a stub router, OSPF cancels the timer to exit startup stub router and remains in stub router mode until the network administrator takes action.
Page 960: Static Area Range Cost
Static Area Range Cost This feature allows a network operator to configure a fixed OSPF cost that is always advertised when an area range is active. This feature applies to both OSPFv2 and OSPFv3. An OSPF domain can be divided into areas to limit the processing required on each router.
Page 961: Lsa Pacing
LSA Pacing OSPF refreshes each self-originated LSA every 30 minutes. Because a router tends to originate many LSAs at the same time, either at startup or when adjacencies are formed or when routes are first learned, LSA refreshes tend to be grouped.
Page 962: Flood Blocking
Flood Blocking OSPF is a link state routing protocol. Routers describe their local environment in Link State Advertisements (LSAs), which are distributed throughout an area or OSPF domain. Through this process, each router learns enough information to compute a set of routes consistent with the routes computed by all other routers.
Page 963 Flood blocking cannot be enabled on virtual interfaces. While the feature could be allowed on virtual interfaces, it is less likely to be used on a virtual interface, since virtual interfaces are created specifically to allow flooding between two backbone routers. So the option of flood blocking on virtual interfaces is not supported.
Page 964: Default Ospf Values
Default OSPF Values OSPF is globally enabled by default. To make it operational on the router, you must configure a router ID and enable OSPF on at least one interface. Table 35-1 shows the global default values for OSPF and OSPFv3. Table 35-1.
Page 965 Table 35-2 shows the per-interface default values for OSPF and OSPFv3. Table 35-2.
