High Availability (HA)
In an active/active configuration, the HA LED only indicates HA
status for the local firewall and has two possible states (green
or off); it does not indicate HA connectivity of the peer. Green
indicates that the firewall is either active-primary or
active-secondary and off indicates that the firewall is in any
other state (for example, non-functional or suspended). |
