WebKey points about trunk ports are: The traffic on a trunk port is kept separate through identifying tags. Each tag identifies the VLAN the packet came from. The tags are placed in the header each time the packet reaches a new switch in the network. This tagging system is labeled 802.1q by the IEEE. WebThe C-bridge UNI port is capable of identifying the customer 802.1Q tag and inserting or removing an S-tag on the packet on a per service instance or C-VLAN basis. A C-VLAN tagged service instance allows service instance selection and identification by C-VLAN. The 802.1ad customer user network interfaces (C-UNIs) implement the C-component.
