Link Aggregation
17.1 Overview
This chapter shows you how to logically aggregate physical links to form one
logical, higher-bandwidth link.
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 beginning port of each trunk group must be physically connected to form a
trunk group.
17.1.1 What You Can Do
• Use the Link Aggregation Status screen ( Section 17.2 on page 159 ) to view
ports you have configured to be in the trunk group, ports that are currently
transmitting data as one logical link in the trunk group and so on.
• Use the Link Aggregation Setting screen ( Section 17.3 on page 161 )
to
configure to enable static link aggregation.
• Use the Link Aggregation Control Protocol screen ( Section 17.4 on page
163 )
to enable Link Aggregation Control Protocol (LACP).
17.1.2 What You Need to Know
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.
See Section 17.5.1 on page 164 for a static port trunking example.
