Mushtaq,
Once you configure Lock and Key the default telnet port (23) will be used to
"unlock" telnet. You need to configure "rotary x" under line vty to be able
to telnet to the box itself:
line vty 0 4
password unlock
logging synchronous
autocommand access-enable host timeout 1440
transport input telnet ssh
line vty 5 100
password unlock
autocommand access-enable host timeout 1440
transport input telnet ssh
line vty 101 150
password cisco
rotary 1
transport input telnet ssh
line vty 151 181
password cisco
logging synchronous
rotary 1
transport input telnet ssh
In the example above line vty 0 100 will be used only to unlock the lock and
key, and line vty 101 181 will be used to telnet to the box itself on port
3001 (you must issue the command telnet x.x.x.x 3001 from your PC). You can
also reverse it and have the command rotary 1 under line vty 0 100 and
nothing under line vty 101 181. The rotary can be from 1 to 99 and the ports
will be 3001 to 3099 respectively.
