Changing the Telnet Service Port Number

To change the TCP port the WSS listens on for Telnet connections, use the following command:

set ip telnet port-num

Caution! If you change the Telnet port number from a Telnet session, WSS Software immediately ends the session. To open a new management session, you must Telnet to the switch with the new Telnet port number.

Resetting the Telnet Service Port Number to Its Default

To reset the Telnet management service to its default TCP port, use the following command:

clear ip telnet

Managing Telnet Server Sessions

Use the following commands to manage Telnet server sessions:

show sessions admin

clear sessions admin telnet [session-id]

These commands display and clear management sessions from a remote client to the WSS’s Telnet server.

Note. If you type the clear sessions admin telnet command from within a Telnet session, the session ends as soon as you press Enter.

To display the Telnet server sessions on an WSS switch, type the following command:

23x0# show sessions admin
Tty	Username	Time (s)	Type
-------	--------------------	--------	----
tty0		3644	Console
tty2	tech	6	Telnet
tty3	sshadmin	381	SSH

3 admin sessions

To clear all Telnet server sessions, type the following command:

23x0# clear sessions telnet

This will terminate manager sessions, do you wish to continue? (yn) [n]y Cleared telnet session on tty2
