Configuring The Switch Module Through The Telnet Interface; Connecting To The Switch Module - IBM Brocade 4 Gb SAN Switch Module Installation Manual

4 Configuring the switch module through the
Telnet interface
The switch module contains a Telnet server. This server enables a Telnet client to establish a Telnet
session with the Fibre Channel switch module to retrieve information or to configure parameters
through the command-line interface (CLI). You can perform a variety of fabric and switch-
management tasks through an Ethernet connection by using the CLI.
You can access the Telnet interface in two ways:
• In the blade server chassis management-module Web interface
• In a command-line window on a network-management workstation
To configure the switch module through the Web interface, the Internet protocol (IP) address and
subnet masks must be compatible, and the following configuration settings in the management
module must be enabled:
• Switch-module external ports
• External management for external ports
To access a switch module from a network-management workstation, make sure it is connected to an
external blade server chassis management-module Ethernet port.
To enable the configuration settings in the management-module Web interface, click I/O Module
Tasks → Admin/Power/Restart.
Important: Before configuring the switch module, make sure that the management modules in the
blade server chassis are correctly configured. In addition, to access and manage the switch module
from an external environment, you might have to enable certain features, such as the external ports
and external management over all ports. See your blade server chassis Installation and User's
Guide on the Resource CD for more information. For information about configuring the switch
module, see the Brocade Fabric OS Command Reference Manual on the Resource CD.

The sample screens that appear in this document might differ slightly from the screens that are
displayed by your system.

Connecting to the switch module

To use the Telnet program (in VT100-compatible terminal mode) to access and control the switch
module, you must know the IP address for the switch module and have an existing network
connection. If you need to obtain the IP address for the switch module or establish a network
connection, contact your system or network administrator. Be sure to use the correct IP address in
the required commands.
