ANAGEMENT ONFIGURATION
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.
To do...
Enter system view
Configure the interval to send
handshake packets
Configure the holdtime of a
device
By default, the destination MAC address of cluster management multicast packets
(including NDP, NTDP and HABP packets) is 010f-e200-0002, which IEEE reserved
for later use. Since some devices cannot forward the multicast packets with the
destination MAC address of 010f-e200-0002, 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 multicast 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
multicast packets.
Follow these steps to configure the destination MAC address of the cluster
management multicast packets:
To do...
Enter system view
Enter cluster view
Configure the destination
MAC address for cluster
management multicast
packets
Configure the interval to send
MAC address negotiation
broadcast packets for cluster

Adding/Removing a member device
You can manually add a candidate device to a cluster, or remove a member device
from a cluster. These operations must be done through the management device,
otherwise you will be prompted with an error message.
Follow these steps to add/remove a member device:
To do...
Enter system view
Use the command...
