The following figure illustrates a use case for MCT strict mode, followed by a sequence of events.

Strict mode LD is enabled on the MCT 1 cluster client edge port (CCEP) interface that connects to the Client.

  1. MCT 1 generates LD PDUs.
  2. If the Client has the LAG interface configured to support LD, the Client drops the PDUs and there is no loop.
  3. If there is a misconfiguration, the Client floods the PDUs, reaching MCT 2.
  4. MCT 1 then identifies the interface information encoded in the PDUs, shutting down the interface on which the packets were generated.
