Dynamically Creating a Port Channel –
Ports assigned to a common port channel must meet the following criteria:
Ports must have the same LACP system priority.
Ports must have the same port admin key (Ethernet Interface).
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.
