Command Summary
Preparing for Configuration
To configure any Cisco Micro Hubs in a stack, the stack must include at least one
Micro Hub 1503. You can connect to the Micro Hub 1503 to configure it in one of two
ways:
•
Direct Connection through the CONSOLE Port
•
Connection Using Telnet
Direct Connection through the CONSOLE Port
You can configure the Micro Hub 1503, by connecting a terminal or a PC directly to the
hub's CONSOLE port as described in the section "Connecting the CONSOLE Port" in the
chapter "Installing Your Hub."

Page 2: Configuration Using A Pc
Preparing for Configuration Connection Using Telnet If the hub is correctly connected to a network, you can access the hub by using Telnet from anywhere on that network and can use the configuration program to communicate with the hub. Before making a Telnet connection to the hub, you must configure the hub with a valid IP address, subnet mask, and default gateway using the configuration program. -
Page 3: Command Conventions
Command Conventions This section describes some things you might need to know before using the commands to configure the hub. If you are familiar with these conventions, you can skip this section. • Enter commands by typing the text of the command at the configuration prompt and then pressing the Return key. -
Page 4: Configuration Modes
Press any other key to return to the prompt. Configuration Modes You configure the Micro Hub 1503 (or the attached stack) with the configuration program that is a part of the hub’s firmware. There are two configuration modes: guest mode and administrator mode (also called privileged mode). -

<password> characters. Spaces are not allowed. The first character cannot be a number. Passwords are case sensitive. An example of a valid password is Forgot Your Password? If you forget the password that provides access to administrator-level commands or if you forget the password required for Telnet sessions, you can bypass the password requirement and set a new password. -
Page 6: Configuring The Hub
Configuring the Hub This section describes basic hub configuration. Before you configure a Micro Hub 1503, have the following information available: • IP address and IP subnet mask that you will assign to the hub if you are accessing the configuration program using Telnet or SNMP. - Page 7 Here are two rules that determine hub ID numbers in a stack of hubs: The lowest hub ID number in a stack (1) is always assigned to the hub with another hub connected to its OUT port and with no hub connected to its IN port. The highest hub ID number in a stack (any number from 2 to 5) is always assigned to the hub with no hub connected to its OUT port and with another hub connected to its IN port.
