If a user is logged into a switch and
performs no keystrokes (remains idle) for 5 minutes, the switch will
automatically log the user out. This feature is referred to as an
"idle timeout." If the user forgets to log out and leaves
his or her terminal unattended, this feature would prevent someone
from gaining unauthorized access to the switch by using the
terminal. Although the default setting of this feature is 5 minutes,
is can be altered with the
set logout
command on a set
command-based switch:
Switch> (enable) set logout
[number of minutes]
The example in Figure
shows how to set the automatic session logout to 20 minutes and how
to disable the automatic logout feature.
To configure a timeout on a Cisco IOS
command-based switch, you must first choose the line (console or vty)
to apply it to and then specify the amount of time. This works just
as a router would. The commands to set the timeout on the console
port of a Cisco IOS command-based switch to 20 minutes are shown in
Figure .
