    This capability is similar to the industry standard “User Roles” feature. The main difference is that the Administrative Profile is obtained via authentication rather than via authorization. This was necessary because Dell PowerConnect does not support AAA authorization of users.

    If the successful authentication method does not provide an Administrative Profile for a user, then the user is permitted access based upon the user’s privilege level (as in previous releases). This means that if a user successfully passes enable authentication, the user is permitted access to all commands. This is also true if none of the Administrative Profiles provided are configured on the switch.

    IGMP Snooping Commands Snooping of Internet Group Management Protocol (IGMP) messages is a feature that allows PowerConnect switches to forward multicast traffic intelligently on the switch. Multicast traffic is traffic that is destined to a host group. Host groups are identified by the destination MAC address, i.e. the range 01:00:5e:00:00:00-01:00:5e:7f:ff:ff:ff for IPv4 multicast traffic or 33:33:xx:xx:xx:xx for IPv6 multicast traffic.

If a query is not received on an interface within a specified length of time (multicast router present expiration time), that interface is removed from the list of interfaces with multicast routers attached. The multicast router present expiration time is configurable using management.

  • Page 569: Iscsi Optimization Commands

    iSCSI Optimization Commands iSCSI Optimization provides a means of performing configuration specific to storage traffic and optionally giving traffic between iSCSI initiator and target systems special Quality of Service (QoS) treatment. iSCSI Optimization is best applied to mixed-traffic networks where iSCSI packets constitutes a portion of overall traffic.
  • Page 570: Iscsi Aging Time

    iSCSI Optimization borrows ACL lists from the global system pool. ACL lists allocated by iSCSI Optimization reduce the total number of ACLs available for use by the network operator. Enabling iSCSI Optimization uses one ACL list to monitor for iSCSI sessions. Each monitored iSCSI session utilizes two rules from additional ACL lists up to a maximum of two ACL lists.
  • Page 571: Iscsi Cos

    • When aging time is increased, current sessions will be timed out according to the new value. • When aging time is decreased, any sessions that have been dormant for a time exceeding the new setting will be immediately deleted from the table. All other sessions will continue to be monitored against the new time out value.

  • Page 633: Port Channel Commands

    Port Channel Commands A port channel is a set of one or more links that can be aggregated together to form a bonded channel (Link Aggregation Group or LAG). Individual conversations in a particular direction always travel over a single link in the port channel, however, in aggregate, the bandwidth usage of all of the links is fairly evenly distributed.
  • Page 634: Vlans And Lags

    an additional parameter static which makes this LAG not require a partner system running Link Aggregation Control Protocol (LACP) to be able to aggregate it's member ports. A static LAG does not transmit or process received LACPDUs, that is, the member ports do not transmit LACPDUs and all the LACPDUs it may receive are dropped.
  • Page 635: Port Channels

    Port Channels Trunking, which is also called Port Channels or Link Aggregation, is initiated and maintained by the periodic exchanges of Link Aggregation Control PDUs (LACPDUs). From a system perspective, a LAG is treated as a physical port. A LAG and a physical port use the same configuration parameters for administrative enable/disable, port priority, and path cost.
  • Page 636: Enhanced Lag Hashing

    • Source/Destination IP and source/destination TCP/UDP Port fields of the packet. Enhanced LAG Hashing PowerConnect devices based on Broadcom XGS-IV silicon 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.

  • Page 657: Qos Commands

    QoS Commands Quality of Service (QoS) technologies are intended to provide guaranteed timely delivery of specific application data to a particular destination. In contrast, standard IP-based networks are designed to provide best effort data delivery service. Best effort service implies that the network delivers the data in a timely fashion, although there is no guarantee.
  • Page 658: Layer 2 Acls

    A user configures an ACL permit rule to force its matching traffic stream to a specific egress interface, bypassing any forwarding decision normally performed by the device. The interface can be a physical port or a LAG. The redirect interface rule action is independent of, but compatible with, the assign queue rule action.
  • Page 659: Queue Mapping

    – Untrusted Port Default Priority • Queue Configuration This enables PowerConnect switches to support a wide variety of delay sensitive video and audio multicast applications. CoS mapping tables, port default priority, and hardware queue parameters may be configured on LAG interfaces as well as physical port interfaces. Queue Mapping The priority of a packet arriving at an interface is used to steer the packet to the appropriate outbound CoS queue through a mapping table.
  • Page 660: Commands In This Chapter

    GMRP Commands The GARP Multicast Registration Protocol provides a mechanism that allows networking devices to dynamically register (and de-register) Group membership information with the MAC networking devices attached to the same segment, and for that information to be disseminated across all networking devices in the bridged LAN that support Extended Filtering Services.
  • Page 962: Gmrp Enable

    The registration and de-registration of membership results in the multicast table being updated with a new entry or the existing entry modified. This ensures that the networking device receives multicast frames from all ports but forwards them through only those ports for which GMRP has created Group registration entry (for that multicast address).
