Configuring the telnet interface

Telnet is enabled by default. To prevent users from passing clear text passwords over the network when
they connect to the switch, you can disable the telnet interface.
NOTE:
Before disabling the telnet interface, make sure you have an alternate method of establishing a
connection with the switch.

How to disable telnet

1.
Connect to the switch and log in as admin.
Connect through some other means than telnet: for example, through SSH.
2.
Enter the following command:
configure telnetd
3.
In response to the System Services prompt, type y.
4.
In response to the telnetd prompt, type off.
The telnet interface is disabled. If you entered the command during a standard telnet session, the
session terminates.
switch:admin> configure telnetd
Not all options will be available on an enabled switch.
To disable the switch, use the "switchDisable" command.
