When you enable LACP, you can configure each link in the LACP port channel for the port priority.
To configure the LACP link mode and port priority, perform this task:
Step 3
switch(config-if)# channel-group
number mode {active | on | passive}

When you run port channels with no associated protocol,
the port-channel mode is always on.
The default port-channel mode is on.
switch(config-if)# no channel-group
number mode
Returns the port mode to on for the specified interface.
