Multi-Chassis LAG

This section describes the Multi-Chassis LAG (MC-LAG) concept. MC-LAG is an extension of a
LAG concept that provides node-level redundancy in addition to link-level redundancy provided
by "regular LAG".
Note: This feature is supported only on 7210 SAS-R6,7210 SAS-X, 7210 SAS-M, 7210 SAS-T,
and 7210 SAS-Mxp network mode. It is not supported in 7210 SAS-T and 7210 SAS-M access-
uplink mode.
Typically, MC-LAG is deployed in a network-wide scenario providing redundant connection
between different end points. The whole scenario is then built by combination of different
mechanisms (for example, MC-LAG and redundant pseudowire to provide e2e redundant p2p
connection or dual homing of DSLAMs in Layer 2/3 TPSDA).
NOTE: The 7210 SAS platforms configured in access-uplink mode cannot peer with an MC-
LAG-enabled node since it does not implement MC-LAG protocol. In other words, 7210 SAS-
M,T in access-uplink mode cannot provide MC-LAG server functionality. Instead they can be
used as MC-LAG clients, with the platforms connected to a head-end node that support MC-LAG
server functionality. These platforms connect to the head-end node using LAG.
