Hello,

Dynamic Fabric Service (DFS) is used for device pairing. In an all-active gateway scenario, the DFS function is invoked. Specifically, the DFS function is implemented by configuring a DFS Group on all-active gateway devices, enabling heartbeat packet exchange between these devices. A nickname or an IP address needs to be bound to the DFS Group. The bound nickname or IP address is used to communicate with remote devices.
When a neighbor relationship is established between all-active devices using the DFS protocol, the devices can synchronize ARP entries for traffic forwarding.
The all-active devices periodically send heartbeat packets to detect faults. If heartbeat packets time out, the DFS neighbor relationship becomes invalid.

For details, see https://support.huawei.com/hedex/hdx.do?docid=EDOC1100079501&id=EN-US_TOPIC_0141192345&text=What%2520Are%2520the%2520Mechanisms%2520and%2520Principles%2520of%2520the%2520All-Active%2520Gateway%2520and%2520DFS%2520Heartbeat%2520Detection%253F&lang=en.

Hope to help you!
