[ 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 3-4.
