Systems and methods for deriving unique MAC address for a cluster

Abstract:

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) (referred to as the “source MAC node”) will sync its MAC addresses of CLAGs to all nodes in a cluster. 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 a source MAC node is present in the cluster.

Abstract(Chinese):

由于集群LAG（CLA或CLAG）是跨群集节点分布的链路聚合，所以在所有集群节点上都将使用相同的MAC地址作为CLAG。集群中的每个节点将为所有集群LAG导出唯一的MAC地址。当形成集群时，集群配置协调器（COO）（称为“源MAC节点”）将将其CLAG的MAC地址同步到集群中的所有节点。相同的MAC地址可以用于从那时起所有节点上的CLA，直到源MAC节点从群集中移除。即使CCO由于某些原因而改变，只要源MAC节点存在于集群中，CLAG MAC将不会更改。
