Dell EMC SmartFabric OS10 User Guide Release 10.5.0

A trunk port can be a member of multiple VLANs set up on an interface. A trunk port transmits 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 node/slot/port[:subport]

2. Change 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 vlan-id

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
