Setting Up the Switch
Although it is possible to establish nested Telnet sessions, Avaya
recommends that you establish a separate Tel net session f or each switch t hat
you want to manage. A nested Telnet session occurs when you establish a
Telnet session from a client to one switch, then through that session, open
another Telnet session to a second switch. Having a separate Telnet session
for each switch that you want to manage helps to avoid confusion.
Terminating a Telnet session
To terminate the Telnet session gracefully, exit the management session by
repeatedly typing exit until the switch displays the login prompt. To
terminate the Telnet session from the client, enter the client-specific
command to terminate the session.

Troubleshooting

Tip When you enter CLI commands in a Telnet session, memory is allocated to
hold the CLI command history. Closing the Telnet session abruptly by
terminating the Telnet client appl icat ion doe s not f ree t hi s memor y and ma y
cause the switch to reset. Close the Telnet sessi on graceful ly as explai ned in
the previous paragraph.
Viewing Active Telnet Sessions
To view active Telnet sessions on the switch enter the show sessions
command as shown in the example below. A list of active telnet sessions is
displayed.

Telnet Session Expiration Timer
Once a telnet session is established, the session will remain open while
there is activity. However, if the session is left idle, the session expires and
is automatically terminated base d on the setting of the Telnet inactivity
timer. The default setting for this timer is 900 seconds or 15 minutes.
Setting this timer to 0 deactivates th e inactivity timer so the Telnet session
will not expire.
To set the Telnet inactivity timer, enter Global Configuration m ode and then
the following CLI command:
(configure)# ip telnet inactivity-period <time-out in seconds>
