Telnet Configuration with Authentication Mode Being Password 53
Note that if you configure to authenticate the users in the password mode, the
command level available to users logging in to a switch depends on both the
authentication-mode password command and the user privilege level level
command, as listed in Table 14.
Configuration Example Network requirements
Assume that you are a level 3 AUX user and want to perform the following
configuration for Telnet users logging in to VTY 0:
■
Authenticate users logging in to VTY 0 using the local password.
■
Set the local password to 123456 (in plain text).
■
Commands of level 2 are available to users logging in to VTY 0.
■
Telnet protocol is supported.
■
The screen can contain up to 30 lines.
■
The history command buffer can contain up to 20 commands.
■
The timeout time of VTY 0 is 6 minutes.

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.
