(1) detached: This state indicates that the port is either in the process of being detached or is currently detached from the Aggregator. A port may be detached from the Aggregator used by its Link Aggregation Group as a result of protocol(e.g., Key) changes, or because of System constraints (e.g., exceeding a maximum allowable number of aggregated links, or device failures) at either end of the link. (2) waiting: This state indicates that the mux is waiting to allow for the possibility that other ports may be reconfiguring at the same time. Once the wait_while_timer expires, and once the wait_while_timers of all other ports that are ready to attach to the same Aggregator have expired, the process of attaching the port to the Aggregator can proceed. (3) attached: This state indicates that the port is in the process of being attached to the Aggregator. (4) collecting: This state indicates that collection of frames from the port is enabled. (5) distributing: This state indicates that distribution of frames to the port is enabled. (255) notAvailable: LACP is disabled.
