Additional Trunk Group Rules for Gigabit Ethernet Modules on Chassis Devices
You can configure a multi-slot trunk group on two Gigabit Ethernet modules.
You can configure a maximum of eight ports in the trunk group.
You can configure up to two groups of ports to make the trunk group and the groups must be alike. For
example, you can group two sets of two ports together or two sets of four ports together but you cannot group
a set of two ports with a set of four ports. Each group of ports can contain two or four ports.
Each group of ports must begin with a primary port. On Gigabit Ethernet modules, the primary ports are 1, 3,
5, and 7.
When you specify the ports in the trunk group, you must specify them in ascending numerical order,
beginning with the primary port. For example, to specify a group containing ports 1/1 – 1/4 and 3/1 – 3/4, you
must specify them in the order shown. You cannot specify 3/1 – 3/4 first.
Port configuration for each trunk group is based on the configuration of the primary port. To change port
parameters, you must change them on the primary port. The software automatically applies the changes to
the other ports in the trunk group.
Trunk Group Load Sharing
When you configure a trunk group, you specify whether the trunk group is a "switch" trunk group or a "server" trunk
Switch trunk group – Use this type of trunk group to connect one HP switch or routing switch to another HP
switch or routing switch.
Server trunk group – Use this type of trunk group to connect an HP switch or routing switch to a file server or
single host device.
The HP device load shares across the ports in the trunk group.
