Installation and Basic Configuration Guide
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.
• You can trunk two 10 Gigabit Ethernet ports together. The first port must be in an odd-numbered chassis slot
and the second port must be in the following even-numbered slot. Trunking of 10-Gigabit Ethernet ports
requires software release 07.6.01b or later. See "Configuring a Trunk Group of 10-Gigabit Ethernet Ports" on
page 7-13.
Figure 7.3 shows an example of a valid 2-port trunk group link between devices. The trunk groups in this example
are switch trunk groups, between two HP devices. Ports in a valid 2-port trunk group on one device are connected
to two ports in a valid 2-port trunk group on another device. The same rules apply to 4-port trunk groups.
