telnet server enable
By default, the Telnet server function is
disabled.
3. Enter VTY line view or
class view.
• To enter VTY line view:
line vty first-number
[ last-number ]
• To enter VTY line class
view:
line class vty
Use either command.
A setting in user line view is applied only to
the user line. A setting in user line class
view is applied to all user lines of the class.
A non-default setting in either view takes
precedence over a default setting in the
other view. A non-default setting in user line
view takes precedence over a non-default
setting in user line class view.
A setting in user line view takes effect
immediately and affects the online user. A
setting in user line class view does not
affect online users and takes effect only for
users who log in after the configuration is
completed.
4. Disable authentication.
authentication-mode none
By default, password authentication is
enabled for VTY lines.
In VTY line view, this command is
associated with the protocol inbound
command:
• If the setting of either command is not
the default in VTY line view, the setting
of the other command in VTY line view
takes effect.
• If the settings of both commands are the
defaults in VTY line view, the settings of
the commands in VTY line class view
take effect.
5. (Optional.) Assign a user
role.
user-role role-name
By default, a VTY line user of the default
MDC is assigned the user role
network-operator, and a VTY line user of a
non-default MDC is assigned the user role
mdc-operator.
The next time you attempt to Telnet to the device, you do not need to provide any username or password,
as shown in Figure 9. If th
e maximum number of login users has been reached, your login attempt fails
and the message "All user lines are used, please try later!" appears.
