Dual Controlling Bridges in Ring Topologies (MLAGs)

In an Extended Edge Switching ring topology with dual (redundant) controlling bridges (CBs), This command is available on all Universal switches supported in this document.s are used to synchronize and coordinate the ring state between the two CBs. For more information about redundant CBs, see Dual Controlling Bridges in Ring Topologies (MLAGs).

Two MLAG topology types are supported:

Cross-connect MLAG—requires 48-port bridge port extenders (BPEs) with four trusted ports (for example, V400-48p-10GE4). See Cross-Connect MLAGs.
One-armed MLAG—used for wiring closet with existing cabling limitations or smaller BPEs. See One-Arm MLAGs.
