Understand EtherChannel Inconsistency Detection - Cisco

WebBridge Protocol Data Units (BPDUs) are frames that contain information about the spanning tree protocol (STP). A switch sends BPDUs using a unique source MAC address from its origin port to a multicast address with destination MAC (01:80:C2:00:00:00, [1] or 01:00:0C:CC:CC:CD for Cisco proprietary Per VLAN Spanning Tree ).
