Completing Trunk Configuration
To complete Layer 2 trunk configuration, perform this task:
Command
Step 1
Router(config-if)# no shutdown
Step 2
Router(config-if)# end
Verifying Layer 2 Trunk Configuration
To verify Layer 2 trunk configuration, perform this task:
Command
Step 1
Router# show running-config interface type
slot/port
Step 2
Router# show interfaces [type
switchport
Step 3
Router# show interfaces [type
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Configuration and Verification Examples
This example shows how to configure the Fast Ethernet port 5/8 as an 802.1Q trunk. This example
assumes that the neighbor port is configured to support 802.1Q trunking:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface fastethernet 5/8
Router(config-if)# shutdown
Router(config-if)# switchport
Router(config-if)# switchport mode dynamic desirable
Router(config-if)# switchport trunk encapsulation dot1q
Router(config-if)# no shutdown
Router(config-if)# end
Router# exit

With Release 12.1(13)E and later releases, the VLAN IDs can be 1 to 4094, except for reserved
VLANs (see
Table 9-1 on page
With 12.1 E releases earlier than Release 12.1(13)E, the VLAN IDs can be 1 to 1005.
The default list of VLANs allowed to be pruned contains all VLANs.
Network devices in VTP transparent mode do not send VTP Join messages. On Catalyst 6500 series
switches with trunk connections to network devices in VTP transparent mode, configure the VLANs used
by the transparent-mode network devices or that need to be carried across the transparent-mode network
devices as pruning ineligible.
