Usage Guidelines

This command displays the following information about the specified LACP LAG:
  • LAG
    • Identifies the particular LAG. This number comes from logical port assigned to the LAG and is the LAG group ID.

  • Actor Sys-Pri
    • Shows the system priority for that LAG.

    • If this number is lower than the number displayed for the Partner Sys-Pri, the system you are working on is the controlling partner in the LAG.

  • Actor Key
    • Automatically generated LACP key.

  • Partner MAC
    • Identifies the MAC address for the system connecting to the LAG on the remote end.

  • Partner Sys-Pri
    • Shows the system priority for that LAG on the remote end.

    • If this number is lower than the number displayed for the Actor Sys-Pri, the system at the remote end is the controlling partner in the LAG.

  • Partner Key
    • LACP key automatically generated by the system to which this aggregator is connected.

    • If this number is lower than the number displayed for the Actor Key, the partner system is the controlling partner in the LAG.

  • Agg Count
    • Identifies the number of ports added to the aggregator for that LAG.

  • Member port

  • Port priority

  • Rx State—Receiving state of the port
    • Idle.

    • Initialized.

    • Current—Receiving LACP PDUs.

    • Expired.

    • Defaulted.

  • Sel Logic—Selection state of the port
    • Selected—Ports with a matching admin key on the remote end.

    • Unselected—Ports that failed to meet with a matching admin key on the remote end.

    • Standby—Ports that exceed the number of ports that can be active in the LAG simultaneously. These ports can be moved into selected mode if one of the currently selected ports in the LAG goes down.

  • Mux State—Ability to transmit and collect data of the port.
    • Waiting—Selected port that is waiting for LACP to determine if it can join the aggregator.

    • Attached—Ports ready to be added to the aggregator.

    • Collecting-Dist—Ports that are added to the aggregator and are transferring data.

    • Detached—Ports that cannot be added to the aggregator.

  • Actor Flag—Mux state of the port.
    • A—Activity.

    • T—Timeout.

    • G—Aggregation.

    • S—Synchronization.

    • C—Collecting.

    • D—Distributing.

    • F—Defaulted.

    • E—Expired.

  • Partner Port
    • The operational value of the port number assigned to this link by partner.

  • Up—Yes or no.

  • Enabled—Yes or no.

  • LAG State—Up or Down.

  • Unack count.

  • Wait-for-count.

  • Current timeout.

  • Activity mode.

  • Defaulted action.

  • Receive state.

  • Transmit state.

  • Minimum Active—The minimum number of active links that must be up for the trunk to remain up.

  • Selected count—Number of selected ports in the LAG.

  • Standby count—Number of standby ports in the LAG.

  • LAG Id flag
    • S—Displays information on controlling partner of LAG.

    • T—Displays information on controlled partner of LAG.
