Link Aggregation
18.1 Link Aggregation 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.
18.1.1 What You Can Do
• 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.
• Use the
Link Aggregation Setting
screen (
) to configure to enable static link
aggregation.
• Use the
Link Aggregation Control Protocol
screen (
) to enable Link
Aggregation Control Protocol (LACP).
18.1.2 What You Need to Know
The OLT 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
OLT.
See
for a static port trunking example.
Dynamic Link Aggregation
The OLT adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port trunking.
The IEEE 802.3ad standard describes the Link Aggregation Control Protocol (LACP) for dynamically
creating and managing trunk groups.
When you enable LACP link aggregation on a port, the port can automatically negotiate with the ports
at the remote end of a link to establish trunk groups. LACP also allows port redundancy, that is, if an
operational port fails, then one of the “standby” ports become operational without user intervention.
