Disabling the Telnet Server
To disable the Telnet server, use the NO SERVICE TELNET command in
the Global Configuration mode. Here is the command:
awplus> enable
awplus# configure terminal
awplus(config)# no service telnet
Note
If you disable the server from a remote Telnet management session,
your session ends. To resume managing the unit, establish a local
management session or remote web browser session. If the
maximum number of manager sessions on the switch is set to one,
you must wait for the console timer on the switch to expire before
starting a new manager session. The default setting for the console
timer is 10 minutes.
