Configuring Cluster Management Protocol Packets - H3C S5810 Series Operation Manual

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:
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 (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.
Follow these steps to configure communication between the management device and the member
devices within a cluster:
To do...
Enter system view
Enter cluster view
Configure the interval to send
handshake packets
Configure the holdtime of a
device

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, you can 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.
Follow these steps to configure the destination MAC address of the cluster management protocol
packets:
