SMLocke -
You need to edit the files for the node that hosts the cluster mgt LIF.
You might want to edit the config on all nodes for it to take effect on all node mgt LIFs.
Also, sshd needs to be restarted to read the changes to /etc/ssh/sshd_config
You probably don't need to do this, as long as you don't need to re-edit the config.
It should pick up the edits you make to the motd file.
I rebooted my 8.21 simulator to get it to take.
I hope this response has been helpful to you.
