79.18 Link Aggregation
This section 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.

79.18.1 What You Can Do
• Use the Link Aggregation Status screen (Section 79.19 on page 576) 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 79.20 on page 578) to configure to enable static link
aggregation.
• Use the Link Aggregation Control Protocol screen (Section 79.21 on page 579) to enable Link
Aggregation Control Protocol (LACP).
79.19 Link Aggregation Status
Use the Link Aggregation Status screen 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.
Click PORT > Link Aggregation > Link Aggregation Status in the navigation panel to display the screen as
shown.
