To avoid creating a loop in the network, be sure you enable LACP before
connecting the ports, and also disconnect the ports before disabling
LACP.
u
If the target switch has also enabled LACP on the connected ports, the
trunk will be activated automatically.
u
A trunk formed with another switch using LACP will automatically be
assigned the next available trunk ID.
u
If more than eight ports attached to the same target switch have LACP
enabled, the additional ports will be placed in standby mode, and will
only be enabled if one of the active links fails.
u
All ports on both ends of an LACP trunk must be configured for full
duplex, and auto-negotiation.
u
Ports are only allowed to join the same Link Aggregation Group (LAG) if
(1) the LACP port system priority matches, (2) the LACP port admin key
matches, and (3) the LAG admin key matches (if configured). However,
if the LAG admin key is set, then the port admin key must be set to the
same value for a port to be allowed to join that group.

OTE
:
If the LACP admin key is not set when a channel group is formed
(i.e., it has a null value of 0), the operational value of this key is set to the
same value as the port admin key used by the interfaces that joined the
group (see the show lacp internal command described on page 869 ).
