Link Aggregation Groups

Link aggregation groups (LAGs), which are also known as port-channels, allow you to combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the aggregation as if it were a single link, which increases fault tolerance and provides load sharing. You assign the LAG VLAN membership after you create a LAG. The LAG by default becomes a member of the management VLAN.

A LAG interface can be either static or dynamic, but not both. All members of a LAG must participate in the same protocols. A static port-channel interface does not require a partner system to be able to aggregate its member ports.

Dynamic LAGs use Link Aggregation Control Protocol (LACP) Protocol Data Units (PDUs) to exchange information with their link partners to help maintain the link state. Static LAGs are also supported. When a port is added to a LAG as a static member, it neither transmits nor receives LACP PDUs. The GS510TP and GS110T Smart Switches each support four LAGs.

Static LAGs are supported. When a port is added to a LAG as a static member, it neither transmits nor receives LACP PDUs. GS716T supports 2 LAGs and the GS724T supports 4 LAGs.
