Example of working configuration aggregated interface (LACP) on switches Juniper EX3300-24T and Cisco Catalyst 3560.
Link Aggregation Control Protocol (LACP) is part of an IEEE specification (802.3ad) that allows you to bundle several physical ports together to form a single logical channel. LACP allows a switch to negotiate an automatic bundle by sending LACP packets to the peer.
