Link Aggregation

Link aggregation applies to various methods of combining multiple network connections in parallel in order to increase throughput beyond what a single connection could sustain. It provides redundancy in case one of the links should fail.

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 can’t be added or removed, until the LAG is edited and a member is removed (which can be added back prior to applying); the LACP button then become available for editing.

• Dynamic—A LAG is dynamic if LACP is enabled on it. The group of ports assigned to dynamic LAG are candidate ports. LACP determines which candidate ports are active member ports. The nonactive candidate ports are standby ports ready to replace any failing active member ports.

This section describes how to configure LAGs.
