port on Layer 2 switches Mac Address usage **Why each and every single port on Layer 2 switches need to have it's own MAC address? This question has been asked and answered with each has it's own MAC and one of the purposes was STP protocol use. My question is that are these mac addresses used for etherchannel load balancing whenever the portchannel configured to load balance based on src-dst mac?is the source mac in cisco command indicating to the port mac address? Thanks, Ethem

No, the source mac address that used in the algorithm is the source mac address in the Ethernet frame to be transmitted (I.E. the mac address of the host that sent the frame), it has nothing to do with the switch port mac address.

(and many switches don't have a per-port mac address).
