CHAPTER 21
Configuration: Link Aggregation
21.1 Overview
This section provides information for Link Aggregation in Configuration.
This chapter shows you how to logically aggregate physical links to form one logical, higher
bandwidth link.
21.1.1 What You Can Do in this Chapter
The Link Aggregation screen (Section 21.2 on page 123) displays global, LAG management, LAG
port, and LACP port settings.
21.2 Link Aggregation
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.
21.2.1 The Global Screen
