 Finally, turn on UDLD to manage the one-way link detection. There's no mention about anything requiring aggressive mode, so that part is up to you. There are global commands for UDLD as well, so be careful with that. Global commands are for fiber ports. Interface commands are for copper ports.

What we expect to see here is that each group has a status of “SU” meaning the channel is a L2 port-channel, and it is “In Use”. For our individual ports make sure you see the (P) meaning the port is part of the port channel Cat3550-1#sh etherchan sum Flags: D - down P - bundled in port-channel I - stand-alone s - suspended H - Hot-standby (LACP only) R - Layer3 S - Layer2 U - in use f - failed to allocate aggregator M u w d
