1-11Configuring Communication Between the Management Device and the MemberDevices Within a ClusterIn a cluster, the management device and member devices communicate by sending handshakepackets to maintain connection between them. You can configure interval of sending handshakepackets and the holdtime of a device on the management device. This configuration applies to allmember devices within the cluster. For a member device in Connect state:z If the management device does not receive handshake packets from a member device within theholdtime, it changes the state of the member device to Disconnect. When the communication isrecovered, the member device needs to be re-added to the cluster (this process is automaticallyperformed).z If the management device receives handshake packets from the member device within theholdtime, the state of the member device remains Active.Follow these steps to configure communication between the management device and the memberdevices within a cluster:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Configure the interval to sendhandshake packets timer interval Optional10 seconds by defaultConfigure the holdtime of adevice holdtime hold-time Optional60 seconds by defaultConfiguring Cluster Management Protocol PacketsBy 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 lateruse. Since some devices cannot forward the multicast packets with the destination MAC address of0180-C200-000A, cluster management packets cannot traverse these devices. For a cluster to worknormally in this case, you can modify the destination MAC address of a cluster management protocolpacket without changing the current networking.The management device periodically sends MAC address negotiation broadcast packets to advertisethe destination MAC address of the cluster management protocol packets.Follow these steps to configure the destination MAC address of the cluster management protocolpackets:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Configure the destination MACaddress for clustermanagement protocol packetscluster-mac mac-addressRequiredThe destination MAC addressis 0180-C200-000A by default.
