Hi All,
I have just upgraded my WS-2960G-48TC Switches, enabled SSH but I can access the Switch using both protocols - how can I disable Telnet and permit SSH

You will need to configure ssh access into the vty lines as follows:
line vty 0 4
transport input ssh
You will also need to create keys as follows:
crypto key generate rsa usage modulus 1024
Hope this helps

Under VTY config configure transport input ssh
This will disable telnet on the vty lines

The above two messages are correct. However, you will need to type that command on vty 0 15 as well to ensure all vty lines require ssh connections.

Hi Michael Buskin, With the addition of Narayan's post I'd like to suggest you to put " transport input all" under line vty 0 4. Thanks Goutam

Gautam,
Transport input all would enable telnet on the VTY lines which the user wants to disable :-)

Hi Narayan, thanks you are right, just ignore the “disable telnet†I was sleepy. :) Thanks Goutam
