Operation Command Description

idle-timeout minutes
[ seconds ]
Optional
The default timeout time of a
user interface is 10 minutes.
With the timeout time being
10 minutes, the connection to
a user interface is terminated
if no operation is performed in
the user interface within 10
minutes.
You can use the idle-timeout
0 command to disable the
timeout function.
Note that if you configure not to authenticate the users, the command level available to
users logging into a switch depends on both the authentication-mode none command
and the user privilege level level command, as listed in
Table 3-5.
