I'm trying to setup LACP (Cisco 6513) on an Apple XServe but I cannot get both ports to be working simultaneously. I have successfully set up the 4 other Xserves but this one will not work. When I do a "sh etherchannel 27 summary" it shows one port in Po27(SU) and the other in Po27B(SU) and it is waiting to be aggregated.
I can get each port to work fine on a Catalyst 2950, the server's motherboard and NIC's have been swapped out to test, and other servers work fine on the ports, just not this server.
At this point we have no idea where to go but are convinced the problem has to come from the switch somewhere.
