Which of the following statements is incorrect about information transmission through the heartbeat link between two firewalls that work in hot standby mode?
A.
Heartbeat packets are sent to synchronize configuration commands and status information between the two firewalls.
B.
Heartbeat packets are periodically sent by the two firewalls to check whether the peer device is alive.
C.
VGMP packets are sent to check the status of the peer device, so as to determine whether a switchover is required.
D.
Configuration consistency check packets are sent to check whether key configurations of the two firewalls are consistent.
In Huawei firewall hot standby, the heartbeat link is mainly used to maintain the backup relationship and monitor peer status. Through this link, the two firewalls periodically exchange heartbeat packets to confirm whether the peer device is alive and operating normally. This makes statement B correct. The heartbeat link also carries VGMP-related packets , which help the devices determine their active or standby roles and decide whether a switchover is necessary when faults or status changes occur. Therefore, statement C is also correct.
In addition, the firewalls can exchange configuration consistency check information to verify whether key configurations on both devices match, so statement D is correct as well.
The incorrect statement is A . Configuration and status synchronization between hot standby firewalls is not described simply as heartbeat packets being used to synchronize configuration commands and status information. Heartbeat packets are mainly for liveness detection and status maintenance , while configuration or session synchronization is handled by dedicated hot standby synchronization mechanisms rather than ordinary heartbeat packets themselves. Therefore, A is the incorrect statement.
