Telnet Session Expiration Timer

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 based 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 the inactivity timer so the Telnet session will not expire.

To set the Telnet inactivity timer, enter Global Configuration mode and then the following CLI command:

(configure)# ip telnet inactivity-period <time-out in seconds>

Table�9 lists the minimum, maximum, and default values for the Telnet inactivity timer.

CAUTION: Avaya recommends that you not disable the inactivity timer. If the inactivity timer is disabled and the maximum number of Telnet sessions is open, none of them will expire. Subsequent attempts to establish a Telnet session will fail. Additionally, idle Telnet sessions may represent security risks.
