Link Aggregation Overview
Link Aggregation Control Protocol (LACP) is part of the IEEE specification (802.3az) that
enables you to bundle several physical ports together to form a single logical channel (LAG).
LAGs multiply the bandwidth, increase port flexibility, and provide link redundancy between
two devices.
Two types of LAGs are supported:
•
Static
—The ports in the LAG are manually configured. A LAG is static if LACP is
disabled on it. The group of ports assigned to a static LAG are always active
members. After a LAG is manually created, the LACP option cannot be added or
