Setting a Telnet Password for a Terminal Line
When you power-up your switch for the first time, an automatic setup p rog ram run s t o as sig n IP
information and to create a default configuration for continued use. The setup program a lso prompts you
to configure your switch for Telnet access through a password. If you did not configure this password
during the setup program, you can configure it now through the command -li ne i nte rface (C LI).
Beginning in privileged EXEC mode, follow these steps to configure your switch for Telnet access:
To remove the password, use the no password global configuration command.
This example shows how to set the Telnet password to let45me67in89:
Switch(config)# line vty 10
Switch(config-line)# password let45me67in89
Configuring Username and Password Pairs
You can configure username and password pairs, which are locally stored on the switch. These pairs are
assigned to lines or ports and authenticate each user before that user can access the switch. If you have
defined privilege levels, you can also assign a specific privilege level (with associated rights and
privileges) to each username and password pair.
