OS10 Enterprise Edition User Guide Release 10.4.0E(R3)


Trunk mode

A trunk port can be a member of multiple VLANs set up on an interface. A trunk port can transmit traffic for all VLANs. To transmit traffic on a trunk port with multiple VLANs, OS10 uses tagging or the 802.1q encapsulation method.

  1. Configure a port in INTERFACE mode.
    interface ethernet 
  2. Change the Switchport mode to Trunk mode in INTERFACE mode.
    switchport mode trunk
  3. Enter the allowed VLANs on the trunk port in INTERFACE mode.
    switchport trunk allowed vlan 

Configure port in trunk mode

OS10(config)# interface ethernet 1/1/6
                                 OS10(conf-if-eth1/1/6)# switchport mode trunk 
                                 OS10(conf-if-eth1/1/6)# switchport trunk allowed vlan 108

                                 switchport trunk allowed vlan 108
                                 no shutdown
                                 interface vlan1
