The deactivate wasnt accepted as it complained reth3.0 didnt exist!
When i do a show int ge-2/0/14 terse on the primary node - node 0 - it replies
Interface Admin Link Proto Local Remote
ge-2/0/14 up up
ge-2/0/14.0 up up aenet --> reth3.0
But the same command when i cli onto node 1 is:
Interface Admin Link Proto Local Remote
ge-2/0/14 up up
ge-2/0/14.0 up up aenet
So it looks like a mismatch between cluster members. When i look at the config as node 1 displays it, it appears correct.
