4-36 Port Configuration
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 using the set eapol command ( page 15‐17 ) and ports that
would otherwise aggregate are not 802.1X authorized.
The LACP implementation on the D‐Series device will allow up to physical 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.
When an existing dynamically created LAG is reduced to one port, the D‐Series removes the LAG
from its VLAN and adds the remaining underlying port to the VLAN. For this reason, you should
ensure that the LAG and all the ports in the LAG are assigned to the egress list of the desired
VLAN. Otherwise, when the LAG is removed, the remaining port may be assigned to the wrong
VLAN. The other option is to enable the singleportlag feature as described in “
set lacp
singleportlag ” on page 4‐41.
Commands
show lacp
Use this command to display information about one or more aggregator ports.
Syntax
show lacp [port-string]
Note: To aggregate, underlying physical ports must be running in full duplex mode and must be of
the same operating speed.
