I have 2 Juniper SSG140's fully configured that I am trying to set up as a pair. Followed the basic active/passive config guide on the Juniper website and the master takes all the config with no issues, however as soon as I enter the 'set nsrp cluster id 1' cmd on the backup device it freezes and won't come back until it's rebooted. When it comes back up it's without the cluster ID set.
Any ideas of why this happens? please just let me know what config you need to see in order to help with this issue.
