Configuring the switch through the Telnet interface

Note: Telnet is disabled by default.
The switch supports a command-line interface (CLI) that you can use to configure
and control the switch over the network through the Telnet program. You can use
the CLI to perform many basic network-management functions. In addition, you
can configure the switch for management through an SNMP-based
network-management system. The following sections describe how to use the
Telnet interface to access the switch, change its settings, and monitor its operation.

Connecting to the switch

If you know the IP address for the switch and you have an existing network
connection, you can use the Telnet program from an external management station
or the management module to access and control the switch. The management
station and the switch must be on the same IP subnet. If you have to obtain the IP
address for the switch or establish a network connection, contact your system or
network administrator. Be sure to use the correct IP address in the required
command, as specified in "Accessing the main menu."

Accessing the main menu

To connect to the switch through the Telnet interface, complete the following steps:
1. From a DOS command-line prompt, type telnet x and press Enter.
2. If you do not have an assigned initial password, in the Password field, type the
Important: The apply command changes the currently active configuration. If you
want your change to persist beyond the next reboot of the switch, you must enter
the save command. This command stores the current switch configuration and all
changes in nonvolatile memory.
For more information about configuring through the CLI, see the Lenovo Application
Guide for the switch.

Configuring the switch through the serial-port interface

The mini-USB serial port provides basic communication through a terminal
emulation program (such as Hyperterminal). Because messages from the power-on
self-test (POST) and all initialization information are transmitted through the serial
port, you can use the serial port to log in to the switch and access and configure
the internal switching firmware.
