SSH2 for Cisco and Netscreen

Many Cisco IOS devices support SSH2 version 12 and later. Netscreen devices from version 5 and later of the IOS also support SSH2.

To enable CatTools to connect to a Netscreen device use a variant of the SSH2 protocol called SSH2-nopty.

This is in relation to the pseudo terminal that is used in *nix when using SSH connections to a command processor, but may not be required by network devices.
