telnet cisco 1721

Hello

I am trying to disable telnet on the router and i am getting back a message 'can't delete last 5 vty lines' after i enter the no line vty 0 4 command. I can enter other commands within line vty but i can't disable it. It is ios 12.2. Thanks

Re: telnet cisco 1721

If you can't delete lines 5 to 15, try disable login to them:

line vty 5 15

no login

You can do this to lines 0 - 4.

Also you can disable telnet:

line vty x y

transport input none

Or apply an ACL

access-list 10 deny any

line vty x y

access-class 10 in

Hope it helps
