44 CHAPTER 2: LOGGING IN THROUGH THE CONSOLE PORT
Note that the level the commands of which are available to users logging in to a
switch depends on the authentication-mode scheme
[ command-authorization ] command, the user privilege level level command,
and the service-type terminal [ level level ] command, as listed in Table 9.
Configuration Example Network requirements
Assume the switch is configured to allow you to login through Telnet, and your
user level is set to the administrator level (level 3). After you telnet to the switch,
you need to limit the console user at the following aspects.
■ Configure the name of the local user to be guest.
■ Set the authentication password of the local user to 123456 (in plain text).
Set the timeout time for the user
interface
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.
