AT-8100 Switch Command Line User's Guide
The LINE_ID parameter has a range of 0 to 9. The following example of
the command toggles off remote authentication on VTY line 0.
awplus> enable
awplus# configure terminal
awplus(config)# line vty 0
awplus(config-line)# no login authentication
Now, the switch uses the local manager accounts, instead of the remote
accounts, to authenticate the user name and password when an
administrator establishes a Telnet or SSH management session on VTY
line 0.
The following example reactivates remote authentication on VTY line 0:
awplus> enable
awplus# configure terminal
awplus(config)# line vty 0
awplus(config-line)# login authentication
