Command Usage
• Ports are only allowed to join the same LAG if (1) the LACP system priority
matches, (2) the LACP port admin key matches, and (3) the LACP port
channel key matches (if configured).
• 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. Note that when the LAG is no longer
used, the port channel admin key is reset to 0.
