Description: If off(1) then this link has not been enabled for trunking. If closed(2) then this link has not yet received any Trunking PDUs. If oneway(3) then incoming Trunking PDUs do not indicate that our PDUs are being successfully received by the far end. If joined(4) then this link is actively participating in the trunk group. If perturbed(5) then this link is actively participating in the trunk group; however, the transmission of data packets has been temporarily stopped due to a change in membership of the group. If helddown(6) then an error has been detected and the link is being held out-of-service until the error clears. If broken(7) then this link has been configured for trunking, but the port is physically non-operational.
