Configuring communication between the management device
and the member devices within a cluster
In a cluster, the management device and member devices communicate by sending handshake packets to
maintain connection between them. You can configure interval of sending handshake packets and the
holdtime of a device on the management device. This configuration applies to all member devices within
the cluster. For a member device in Connect state, the following rules apply:
• If the management device does not receive handshake packets from a member device within the
holdtime, it changes the state of the member device to Disconnect. When the communication is
recovered, the member device needs to be re-added to the cluster, and this process is automatically
performed.
• If the management device receives handshake packets from the member device within the holdtime,
the state of the member device remains Active.

Configuring cluster management protocol packets
By default, the destination MAC address of cluster management protocol packets—including NDP, NTDP
and HABP packets—is a multicast MAC address 0180-C200-000A, which IEEE reserved for later use.
Since some devices cannot forward the multicast packets with the destination MAC address of 0180-
C200-000A, cluster management packets cannot traverse these devices. For a cluster to work normally in
this case, modify the destination MAC address of a cluster management protocol packet without
changing the current networking.
The management device periodically sends MAC address negotiation broadcast packets to advertise the
destination MAC address of the cluster management protocol packets.
