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.  End with CNTL/Z.

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 

This example shows how to verify the configuration:

Router# show running-config interface fastethernet 5/8

 switchport trunk encapsulation dot1q

end

Router(config-if)# no shutdown 

Activates the interface. (Required only if you shut down 
the interface.)

Router(config-if)# end 

Exits configuration mode.
