Field Description

LACP state

LACP state information:

Role—Role played by the interface. It can be one of the following:

Actor—Local device participating in LACP negotiation.

Partner—Remote device participating in LACP negotiation.

Exp—Expired state. Yes indicates the actor or partner is in an expired state. No indicates the actor or partner is not in an expired state.

Def—Default. Yes indicates that the actor's receive machine is using the default operational partner information, administratively configured for the partner. No indicates the operational partner information in use has been received in an LACP PDU.

Dist—Distribution of outgoing frames. No indicates distribution of outgoing frames on the link is currently disabled and is not expected to be enabled. Otherwise, the value is Yes.

Col—Collection of incoming frames. Yes indicates collection of incoming frames on the link is currently enabled and is not expected to be disabled. Otherwise, the value is No.

Syn—Synchronization. If the value is Yes, the link is considered "in synch." It has been allocated to the correct link aggregation group, the group has been associated with a compatible aggregator, and the identity of the link aggregation group is consistent with the system ID and operational key information transmitted. If the value is No, the link is currently "out of synch," not in the right aggregation.

Aggr—Ability of aggregation port to Aggregate (Yes) or to operate only as an individual link (No).

Timeout—LACP timeout preference. Periodic transmissions of LACP PDUs occur at either a slow or fast transmission rate, depending upon the expressed LACP timeout preference (Long Timeout or Short Timeout).

Activity—Actor or partner's port activity. Passive indicates the port's preference for not transmitting LAC PDUs unless its partner's control value is Active. Active indicates the port's preference to participate in the protocol regardless of the partner's control value.

LACP protocol

Receive state—One of the following values:

Current—The state machine receives an LACP PDU and enters the Current state.

Defaulted—If no LACP PDU is received before the timer for the Current state expires a second time, the state machine enters the Defaulted state.

Expired—If no LACP PDU is received before the timer for the Current state expires once, the state machine enters the Expired state.

Initialize—When the physical connectivity of a link changes or a Begin event occurs, the state machine enters the Initialize state.

LACP Disabled—If the port is operating in half duplex, the operation of LACP is disabled on the port, forcing the state to LACP Disabled. This state is similar to the Defaulted state, except that the port is forced to operate as an individual port.

Port Disabled—If the port becomes inoperable and a "begin" event has not occurred, the state machine enters the Port Disabled state.

Transmit state—Transmit state of state machine. One of the following values:

Fast Periodic—While in this state, periodic transmissions are enabled at a fast transmission rate.

No Periodic—While in this state, periodic transmissions are disabled.

Periodic Timer—Transitory state entered when the periodic timer expires.

Slow Periodic—While in this state, periodic transmissions are enabled at a slow transmission rate.

Mux state—State of the mux state machine for the aggregation port. The state is one of the following values:

Attached—Mux machine initiates the process of attaching the port to the selected aggregator.

Collecting—Yes indicates that the receive function of this link is enabled with respect to its participation in an aggregation. Received frames are passed to the aggregator for collection. No indicates the receive function of this link is not enabled.

Collecting Distributing—Collecting and distributing states are merged together to form a combined state (coupled control). Because independent control is not possible, the coupled control state machine does not wait for the partner to signal that collection has started before enabling both collection and distribution.

Detached—Process of detaching the port from the aggregator is in progress.

Distributing—Yes indicates that the transmit function of this link is enabled with respect to its participation in an aggregation. Frames may be passed down from the aggregator's distribution function for transmission. No indicates the transmit function of this link is not enabled.

Waiting—Mux state machine is in a holding process, awaiting an outcome.
