- A . When the physical line of GE2/0/1 of firewall A is faulty, the link status of GE2/0/0 on USG_A is down, and the indicator of the physical interface is always on.
- B . After the fault is recovered, when the firewall detects that both GE2/0/0 and GE2/0/1 are in the Up state, the state of USG_A switches to master.
- C . After the GE2/0/1 interface recovers from the fault, USG_A works as the backup device of USG_
- E . If GE2/0/2 is also added to link-group 1, when the physical line of GE2/0/1 of firewall A is faulty, the backup of active and standby device information will be interrupted.
