In a CloudFabric solution, the fault detection and fault-tolerant design of the firewall includes ?().
A.
A heartbeat cable is deployed between the two FWs to check the status of the peer FW and the heartbeat link connectivity
B.
It is recommended that each FW and service be connected in a single-arm mode, and the upstream and downstream logical ports fail at the same time, resulting in higher failover performance
C.
Link fault: If any link on the edge leaf of the FW primary connection fails, the M-lag member port goes down, and the double homing becomes single homing, which does not affect the forwarding of FW primary traffic
D.
FW fault: After the FW is switched over to the primary/standby, the FW sends a free ARP packet to trigger the refresh of the forwarding entries on the switch and direct the traffic to the FW standby
