Switch Management Guide

CHANNEL - GROUP
26-3
• If the port channel admin key (lacp admin key - Port Channel) is not
set when a channel group is formed (i.e., it has the null value of 0), this
key is set to the same value as the port admin key (lacp admin key -
Ethernet Interface) used by the interfaces that joined the group.
• However, if the port channel admin key is set, then the port admin key
must be set to the same value for a port to be allowed to join a channel
group.
• If a link goes down, LACP port priority is used to select the backup
link.
