As cluster LAG (CLA or CLAG) is a link aggregation spread across cluster nodes, the same MAC address is to be used for a CLAG on all cluster nodes. Each node in a cluster will derive the unique MAC address for all cluster LAGs. When a cluster is formed, the cluster configuration coordinator (COO) will sync its MAC addresses of CLAGs to all nodes in a cluster (this node may be referred to as the "source MAC node"). The same MAC address may be used for a CLA on all nodes from then onwards till the source MAC node is removed from cluster. Even if the CCO changes due to some reason, CLAG MACs will not be changed as long as source MAC node is present in the cluster. When source MAC node is removed from cluster, the CCO will be selected as new source MAC node and its CLA MACs are synced across the nodes. |
