Configuring VLAN Trunks

Configuring Trunk Ports for Load Sharing

DETAILED STEPS

 

Command or Action

Purpose

Step 1

configure terminal

Enters the global configuration mode.

 

Example:

 

 

Switch# configure terminal

 

Step 2

interface interface-id

Defines the interface that is configured as the IEEE

 

 

802.1Q trunk, and enters interface configuration mode.

 

Example:

 

 

Switch(config)# interface gigabitethernet1/0/2

 

Step 3

switchport trunk native vlan vlan-id

Example:

Switch(config-if)#switchport trunk native vlan 12

Configures the VLAN that is sending and receiving untagged traffic on the trunk port.

For vlan-id, the range is 1 to 4094.

Step 4

end

Returns to privileged EXEC mode.

Example:

Switch(config-if)# end

Step 5

show interfaces interface-idswitchport

Verifies your entries in the Trunking Native Mode VLAN

 

 

field.

 

Example:

 

 

Switch# show interfaces gigabitethernet1/0/2

 

 

switchport

 

Step 6

copy running-config startup-config

(Optional) Saves your entries in the configuration file.

 

Example:

 

 

Switch# copy running-config startup-config
