Cisco ACI uses the Link Aggregation Control Protocol (LACP) to form port channels automatically. LACP allows multiple ports to be aggregated together into a single logical link, providing redundancy and increased bandwidth.
LACP is a layer 2 protocol that runs over Ethernet. LACP uses a multicast address to send and receive control packets. LACP packets are sent every 30 seconds by default.
LACP allows you to configure port channels manually or automatically. If you configure port channels manually, you must manually add or remove ports from the port channel. If you configure port channels automatically, LACP will dynamically configure the port channel based on the ports that are active and the configuration of the devices.
LACP is supported on all Cisco Nexus switches.
