Changing the Login Timer
The login timer is the number of minutes after which an idle session is disconnected.
To change the logout timer value, perform this task in privileged mode:
Task
Change the logout timer value (a timeout value of
0 prevents idle sessions from being disconnected
automatically).

Console> (enable) set logout 10
Sessions will be automatically logged out after 10 minutes of idle time.
Console> (enable)
This example shows how to set the logout timer value to 0, preventing idle sessions from being
disconnected automatically:
Console> (enable) set logout 0
Sessions will not be automatically logged out.

Using Secure Shell Encryption for Telnet Sessions
Note
To use the secure shell encryption(SSH) feature commands, you must be running an encryption image.
Encryption commands are set crypto key rsa, clear crypto key rsa, and show crypto key. See
Chapter 29, "Working with System Software Images,"
for the encryption images.
The SSH feature provides security for Telnet sessions to the switch. SSH is supported for remote logins
to the switch only. Telnet sessions initiated from the switch cannot be encrypted. To use this feature, you
must install the application on the client accessing the switch and you must configure SSH the switch.
The current implementation of SSH supports version 1, both the DES and 3DES encryption methods,
and can be used with RADIUS and TACACS+ authentication. To support authentication for Telnet with
secure shell encryption, use the telnet keyword in the set authentication commands.
