Turn NGFW Engines offline
In the offline state, engines stop processing traffic, but remain otherwise operational and ready to be turned online again.
Engines in the offline state can be turned on either automatically or by an administrator’s command, depending on the configuration.
CAUTION:
When you turn a node offline, it stops processing traffic. On Firewalls, Layer 2 Firewalls, and Master NGFW Engines, traffic is stopped unless other cluster nodes can take over. On Virtual Firewalls, Virtual IPS engines, and Virtual Layer 2 Firewalls, traffic is always stopped. On IPS engines, the behavior depends on the Failure Mode of the interfaces.
