The cluster-multimac command assigns a multicast address to a cluster.
The undo cluster-multimac command restores the default multicast address of the cluster.
By default, the multicast address of the cluster is 0180-C200-000A.
| Parameter | Description | Value |
|---|---|---|
| mac-address | Specifies the multicast MAC address of a cluster. | The value is in the format of H-H-H. Each H stands for a 4-digit hexadecimal number. The value ranges from 0180-C200-0004 to 0180-C200-0007, 0180-C200-0009 to 0180-C200-0010 and 0180-C200-0020 to 0180-C200-002F. The default value is 0180-C200-000A. |
Before setting up a cluster, you need to assign a multicast MAC address to the cluster or use the default multicast MAC address. To enhance the network security or if the default multicast MAC address is being used by other services on the network, you can reassign a multicast MAC address to the cluster within the permitted range. Once the cluster is set up, you cannot change the multicast MAC address of the cluster. All the devices in the cluster must be assigned the same multicast MAC address.
