Can you create an etherchannel between a 3550 switch and a 6509 with a WS-X6K-SUP1A-2GE / WS-F6020A. When I create the port-channel group the message incompatible ports cannot bundle gi0/3 and gi0/4 shows up and unbundles the connection errordisables 1 port. My question is I know the WS-F6020 has a problem with port channel. Cisco states all other cards are okay. Does this include or exlude the WS-6020A?
