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 Layer 2 Switches or Layer 3 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.
5.
If the device at the other end of the trunk group is another Layer 2 Switch or Layer 3 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 10.1
To configure the trunk groups shown in Figure 10.1, enter the following commands. Notice that the commands are
entered on multiple devices.
To configure the trunk group link between FSX1 and the FESX:
NOTE:
The text shown in italics in the CLI example below shows messages echoed to the screen in answer to
the CLI commands entered.
FastIron SuperX Router(config)# trunk e 1/5 to 1/8
Trunk 2 is created for next power cycle.
Please save configuration to flash and reboot.
FastIron SuperX Router(config)# write memory
Write startup-config in progress.
.Write startup-config done.
FastIron SuperX Router(config)# exit
FastIron SuperX Router# reload
To configure the trunk group link between FSX2 and the server:
FastIron SuperX Router(config)# trunk e 1/2 to 1/4
Trunk 0 is created for next power cycle.
Please save configuration to flash and reboot.
FastIron SuperX Router(config)# write memory
Write startup-config in progress.
.Write startup-config done.
FastIron SuperX Router(config)# exit
FastIron SuperX Router# reload
You then configure the trunk group on the FESX.
FESX424 Switch(config)# trunk ethernet 17 to 18
FESX424 Switch(config)# write memory
Write startup-config in progress.
.Write startup-config done.
FESX424 Switch(config)# exit
FESX424 Switch# reload
Example 2: Configuring a Trunk Group That Spans Multiple
Gigabit Ethernet Modules in a Chassis Device
This section shows how to configure a trunk group that spans two modules in a Chassis device.
