15.1 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.
The ONU supports both static and dynamic link aggregation.
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 ONU.

15.1.1 What You Can Do in the Link Aggregation Screens
• The Link Aggregation Status screen lets you view the status of your trunk groups
(Section 15.2 on page
• The Link Aggregation Setting screen lets you configure or enable static link aggregation
(Section 15.3 on page
• The Link Aggregation Control Protocol screen lets you enable dynamic link
aggregation
