Defining a Telnet Password
To be able to use telnet sessions to connect to the switch a user password must be defined. From the serial console, in privileged EXEC mode, execute the following procedure. If not in privileged EXEC mode, use the enable command.
1. Enter global configuration mode by typing the following:
configure terminal
2. Select virtual (vty) lines 0 to 1 for configuration by typing the following:
line vty 0 1
3. Set the unencrypted password (0) to admin by typing the following:
password 0 admin
4. Exit configuration mode by typing the following:
end
5. Save the changes by typing the following:
copy running-config startup-config
 

NOTE: Cisco switches do not support users. When prompted for a username/password, always leave the username field blank.
