 The SSH Version 2 server is supported in Cisco IOS Release 12.3(4)T, 12.3(2)XE, 12.2(25)S, and 12.3(7)JA.<br/><br/>
-The configuration for the SSH Version 2 server is similar to the configuration for SSH Version 1. The '''ip ssh version''' command was introduced so that you may define which version of SSH to configure. If you do not configure this command, SSH by default runs in compatibility mode; that is, both SSH Version 1 and SSH Version 2 connections are honored.
