Installation and Getting Started Guide
Configuring Trunk Groups
The Trunk Group feature allows you to establish multiple high-speed load-sharing links between two HP switches
or routing switches or between an HP switch or routing switch and a server. You can configure from 2 – 4 ports as
a trunk group, supporting transfer rates of up to 4 Gbps of bi-directional traffic.
In addition, on the HP 9304M and HP 9308M, you can configure up to eight ports on two Gigabit Ethernet modules
as a multi-module trunk group. Figure 9.2 shows an example of a configuration that uses trunk groups.
In addition to enabling load sharing of traffic, trunk groups provide redundant, alternate paths for traffic if any of the
Trunk Group application within an HP routing switch network
NOTE: The ports in a trunk group make a single logical link. Therefore, all the ports in a trunk group must be
connected to the same device at the other end.
Trunk Group Connectivity to a Server
To support termination of a trunk group, the server must have either multiple network interface cards (NICs) or a
dual or quad interface card installed. The trunk server is designated as a server with multiple adapters or a single
adapter with multiple ports that share the same MAC and IP address. Figure 9.3 shows an example of a trunk
group between a server and an HP device.
