The following guidelines apply to MC-LAG configurations:
MC-LAG peer nodes must be of the same platform type. For example, 7210 SAS-K 2F6C4T can only peer with another 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C can only peer with another 7210 SAS-K 3SFP+ 8C. 7210 SAS-K 2F6C4T cannot be configured with 7210 SAS-K 3SFP+ 8C as its MC-LAG peer.
MC-LAG is only supported when using MPLS uplinks with network ports. It is not supported with access-uplink ports.
The 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C can also be MC-LAG clients, with an active/standby LAG configuration used to dual-home to access-aggregation routers when using access-uplink ports. In this scenario the user has an option to provision the uplinks as access-uplink ports to dual-home into two aggregation PE routers that are configured as MC-LAG peers.
