Link Aggregation

13.1 Overview

This chapter shows you how to logically aggregate physical links to form one logical, higher-bandwidth link.

13.2What You Can Do

•Use the Static Trunk screen (Section 13.4 on page 78) to aggregate groups of physical ports into one higher capacity link.

•Use the LACP screen (Section 13.5 on page 79) to enable Link Aggregation Control Protocol (LACP).

13.3What You Need to Know

Link Aggregation (Trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.

However, the more ports you aggregate then the fewer available ports you have. A trunk group is one logical link containing multiple ports.

The Switch supports both static and dynamic link aggregation.

Note: In a properly planned network, it is recommended to implement static link aggregation only. This ensures increased network stability and control over the trunk groups on your Switch.

13.3.1 Dynamic Link Aggregation

The Switch adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port trunking.
