Symptom

The port channel members are in a suspended state and the "show int e x/y" command shows that the interface operst is down. The LLFC/PFC operst for the port channel and member ports is up, as shown by the "show interface eth x/y flowcontrol" or "show interface eth x/y priority-flow-control" commands. show port-channel extended ----------------------------------------------------------------------------- Group Port- BundleGrp Protocol Member Ports Channel ----------------------------------------------------------------------------- 1 Po1(SD) accBndlGrp_103_pc31 LACP Eth1/44(s) Eth1/45(s) show inter port-channel 1 flowcontrol -------------------------------------------------------------------------------- Port Send FlowControl Receive FlowControl RxPause TxPause admin oper admin oper -------------------------------------------------------------------------------- Po1 on on on on 0 0

Conditions

Initially have a port channel with LLFC/PFC enabled on it and the port is in the up state with LLFC/PFC operst as up. Upon changing some configuration on the port channel, if the members of the port channel go into the suspended state, this issue may be seen.

Workaround

There is no functional issue. Because the port is in suspended state, no traffic will flow out of it. After the port moves from the suspended to oper up state, LLFC/PFC on those ports will still be up and everything will be programmed.
