Installation and Basic Configuration Guide
NOTE: If you connect the cables before configuring the trunk groups and then rebooting, the traffic on the
ports can create a spanning tree loop.
2. Configure the trunk group on one of the two Routing Switches involved in the configuration.
3. Save the configuration changes to the startup-config file.
4. Dynamically place the new trunk configuration into effect by entering the trunk deploy command at the global
CONFIG level of the CLI.
NOTE: If you are running a software release earlier than 07.5.04, you must reload the software to place a
trunk configuration change into effect.
5. If the device at the other end of the trunk group is another Routing Switch, repeat Steps 2 – 4 for the other
device.
6. When the trunk groups on both devices are operational, reconnect the cables to those ports that are now
configured as trunk groups, starting with the first port (lead port) of each trunk group.
7. To verify the link is operational, use the show trunk command.
Example 1: Configuring the Trunk Groups Shown in Figure 7.1
To configure the trunk groups shown in Figure 7.1, enter the following commands. Notice that the commands are
entered on multiple devices.
USING THE CLI
To configure the trunk group link between Router1 and Router2:
NOTE: The text shown in italics in the CLI example below shows messages echoed to the screen in answer to
the CLI commands entered.
NARouter1(config)# trunk switch e 1/5 to 1/8
Trunk 2 is created for next power cycle.
Please save configuration to flash and reboot.
Router1(config)# write memory
Write startup-config in progress.
.Write startup-config done.
Router1(config)# exit
Router1# reload
NOTE: This example uses devices that are not running software release 07.5.004 or later. Devices running
software earlier than 07.5.004 must be reloaded in order to place trunk configuration changes into effect. On
devices running 07.5.004 or later, you can dynamically place trunk configuration changes into effect by entering
the trunk deploy command at the global CONFIG level of the CLI.
To configure the trunk group link between Router2 and the server:
Router2(config)# trunk server e 1/2 to 1/4
Trunk 0 is created for next power cycle.
Please save configuration to flash and reboot.
Router2(config)# write memory
Write startup-config in progress.
.Write startup-config done.
Router2(config)# exit
Router2# reload
You then configure the trunk group on the HP 2626 Switch.
HP2626(config)# trunk e 17/18 trk1 trunk
HP2626(config)# write memory
