From ExtremeXOS 31.2, W-MLAG and single-homed MLAG support is provided for Fabric Attach. Before ExtremeXOS 31.1, the mappings from MLAG clients were checkpointed to the proxy or server peer. But starting with ExtremeXOS 31.2, the mappings from non-MLAG clients are also checkpointed to the MLAG proxy or server peer node. If the proxy or server is part of a W-MLAG network, then the mapppings from all the clients, irrespective of whether they are part of MLAG or not, are passed to all the peer nodes of the MLAG.
