4.5 Link Aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs).
Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy.
Figure 4-5-1 Link Aggregation
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media types
(UTP/Fiber, or different fiber types), provided they operate at the same speed.
Aggregated Links can be assigned manually (Port Trunk) or automatically by enabling Link Aggregation Control Protocol
(LACP) on the relevant links.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port attributes
to a non-aggregated port, including auto-negotiation, speed, Duplex setting, etc.
The Managed Switch supports the following Aggregation links :
„ Static LAGs (Port Trunk) – Force aggregared selected ports to be a trounk group.
„ Link Aggregation Control Protocol (LACP) LAGs - LACP LAG negotiate Aggregated Port links with other LACP
ports located on a different device. If the other device ports are also LACP ports, the devices establish a LAG
between them.
