This example shows how to set an interface as an Ethernet trunk port:
switch# configure terminal
switch(config)# interface ethernet 1/3
switch(config-if)# switchport mode trunk

Configuring the Native VLAN for 802.1Q Trunking Ports

If you do not configure this parameter, the trunk port uses the default VLAN as the native VLAN ID.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface {type slot/port | port-channel number}
3. switch(config-if)# switchport trunk native vlan vlan-id
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal

Purpose
Enters global configuration mode.
Specifies an interface to configure, and enters interface configuration
mode.
Sets the interface as an Ethernet trunk port. A trunk port can carry traffic
in one or more VLANs on the same physical link (VLANs are based on
the trunk-allowed VLANs list). By default, a trunk interface can carry
traffic for all VLANs. To specify that only certain VLANs are allowed
on the specified trunk, use the switchport trunk allowed vlan command.
Purpose
Enters global configuration mode.
