Configuring Trunk Groups - HP ProCurve 9304M Installation And Configuration Manual

This chapter describes how to configure trunk groups and 802.3ad link aggregation.
• Trunk groups are manually-configured aggregate links containing multiple ports.
• 802.3ad link aggregation is a protocol that dynamically creates and manages trunk groups.
NOTE: You can use both types of trunking on the same device. However, you can use only one type of trunking
for a given port. For example, you can configure port 1/1 as a member of a static trunk group or you can enable
802.3ad link aggregation on the port, but you cannot do both.

Configuring Trunk Groups

The Trunk Group feature allows you to manually configure multiple high-speed load-sharing links between two HP
Routing Switches or between an HP Routing Switch and a server. You can configure up to 8 ports as a trunk
group, supporting transfer rates of up to 8 Gbps of bi-directional traffic.
In addition to enabling load sharing of traffic, trunk groups provide redundant, alternate paths for traffic if any of the
segments fail.
Figure 7.1 shows an example of a configuration that uses trunk groups.
