Configuring LACP Parameters
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 LACP port Admin Key.
• However, if the “port channel” Admin Key is set (
page 4-194), then the
port Admin Key must be set to the same value for a port to be allowed
to join a channel group.
Note: If the port channel admin key (lacp admin key, page 4-194) is not
set (through the CLI) when a channel group is formed (i.e., it has a
null value of 0), this key is set to the same value as the port admin
key used by the interfaces that joined the group (lacp admin key, as
described in this section and on page 4-193).
