Hi All,
Today we allow Telnet via Line VTY across IOS routers/switches. 1) What configuration changes are required in Line VTY to allow Telnet and SSH? 2) Are there any IOS related dependencies for SSH protocol on routers/switches?

First you'll need the crypto image to configure SSH (look for k9 in the IOS file name). Then you'll need to configure SSH.

Finally add telnet and SSH to the VTY's.
line vty 0 4
transport input telnet ssh
The above command will only allow telnet and ssh. By default all protocols are allowed and the above line provides some additional security.
Hope that helps.
