Method and procedure for loop detection in multi-chassis link aggregation group (MCLAG) deployment within a communications system

摘要

Apparatus and methods described herein relate to an apparatus including a set of ports and a processor operatively coupled to each port of the set of ports. A port from the set of ports can be associated with a port of a multi-chassis aggregate (MCAE) interface and a virtual local area network (VLAN). The processor can generate an untagged data unit and tagged data units. The processor can send the untagged data unit and the tagged data units via the port from the set of ports, and can receive a tagged data unit included in the tagged data units, and/or the untagged data unit. The processor can also forward the received data unit to a destination network peer when the received tagged data unit is associated with the VLAN, and can disable the port of the MCAE interface in response to the port from the set of ports receiving the data unit, when the received data unit is associated with the VLAN.
