Multi-Chassis LAG (MC-LAG) is an extension of a LAG concept that provides node-level redundancy in addition to the link-level redundancy provided by ‟regular LAG”. Typically, MC-LAG is deployed network-wide, along with IP/MPLS, providing redundant connections between different access end points. In a typical MC-LAG deployment, a pair of nodes are configured to be MC-LAG peers (also referred to as MC-LAG servers), and access devices are connected to the MC-LAG peers using LAGs with active/standby LAG groups.
The 7210 SAS-D, 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C platforms can be connected to an MC-LAG-enabled node, such as an MC-LAG server. In particular, these platforms allow for provisioning of links into subgroups in a LAG and support active/standby links. The MC-LAG solution can be achieved with or without subgroups configured.
