LAG Port Parameters

Term Definition
Port Admin Key The port admin key can be set for both the actor and partner side of the link. The admin key only affects the local device. LACP uses this value to determine which underlying physical ports are capable of aggregating. Aggregator ports allow only underlying ports with physical port and LAG admin keys that match to join a LAG. Setting the physical port admin key to a different value than any LAG resource on the device will ensure that this link does not join a LAG. Valid values are 1 - 65535. Default value is 32768.
Port Priority Port priority can be set for both the actor and partner side of the link. The port priority plays a role in determining which set of ports will move to the attached state and pass traffic. The lower port priority, for the port on the system in charge of selecting ports to move to the attached state, determines which ports will actually move to the attached state. If a LAG is made up of ports with different speeds, setting a lower port priority to ports with the desired speed for the LAG will ensure that those ports move to the attached state. Port priority is also used to determine which ports join a LAG if the number of ports available exceeds the number of ports supported for that device. Valid values are 0 - 65535, with lower values designating higher priority. Default value is 32768.
Administrative State
  • A number of port level administrative states can be set for both the actor and partner ports. The following port administrative states are set by default:
  • lacpactive - Transmitting LACP PDUs is enabled.
  • lacptimeout - Transmitting LACP PDUs every 30 seconds. If this state is disabled, LACP PDUs are transmitted every 1 second. Note that the actor and partner LACP timeout values must agree.
  • lacpagg - Aggregation on this port is enabled.
  • lacpsync - Transition to synchronization state is allowed.
  • lacpcollect - Transition to collection state is allowed.
  • lacpdist - Transition to distribution state is allowed.
  • lacpdef - Transition to defaulted state is allowed.
  • lacpexpire - Transition to expired state is allowed.
    Note: It is recommended that you do not change these default states unless you know what you are doing. Contact Extreme Networks customer support should you need assistance modifying port level administrative states.
Partner Default System ID A default partner system ID can be set. This is a default MAC address for the system partner.
LACP PDU processing (Optional) LACP PDU processing can be enabled or disabled for this port.
