LACP EtherChannel Operation

• On - This mode forces the interface to channel without LACP. Interfaces configured in the on mode do not exchange LACP packets
• LACP active - This LACP mode places a port in an active negotiating state. In this state, the port initiates negotiations with other ports by sending LACP packets
• LACP passive - This LACP mode places a port in a passive negotiating state. In this state, the port responds to the LACP packets that it receives but does not initiate LACP packet negotiation

LACP provides the same negotiation benefits as PagP

LACP helps create the EtherChannel link by detecting the configuration of each side and making sure that they are compatible so that the EtherChannel link can be enabled when needed

The modes for LACP are as follows:
