Join Airheads
In older Airwave version you could edit the ~/.ssh/known_hosts file directly. Direct access is no longer permitted in newer versions and I don't see an option in the CLI menus to do this.
You would have to contact TAC for this, as they can login to the shell as root user.Also, can raise a feature request to get this option added to AMP menu.
Thanks Vishnu. I got TAC to get me into the Shell and make the changes I needed.
