clear port mirroring
by comparing operational keys. Aggregator ports allow only underlying ports with keys matching
theirs to join their LAG.
LACP uses a system priority value to build a LAG ID, which determines aggregation precedence.
If there are two partner devices competing for the same aggregator, LACP compares the LAG IDs
for each grouping of ports. The LAG with the lower LAG ID is given precedence and will be
allowed to use the aggregator.
There are a few cases in which ports will not aggregate:
• An underlying physical port is attached to another port on this same switch (loopback).
• There is no available aggregator for two or more ports with the same LAG ID. This can
happen if there are simply no available aggregators, or if none of the aggregators have a
matching admin key and system priority.
• 802.1x authentication is enabled, and ports that would otherwise aggregate are not 802.1X
authorized.
The LACP implementation on the Matrix Series device will allow up to a maximum of four ports
into a LAG. The device with the lowest LAG ID determines which underlying physical ports are
allowed into a LAG based on the ports' LAG port priority. Ports with the lowest LAG port priority
values are allowed into the LAG and all other speed groupings go into a standby state.

Purpose

To disable and re‐enable the Link Aggregation Control Protocol (LACP), to display and configure
LACP settings for one or more aggregator ports, and to display and configure the LACP settings
for underlying physical ports that are potential members of a link aggregation.

Note: Only one LACP system priority can be set on a Matrix Series device, using either the set lacp
asyspri command ("set lacp
on page 4-66).
Note: To aggregate, underlying physical ports must be running in full duplex mode and must be of
the same operating speed.
