WebAug 25, 2006 · The 802.1Q tag is 4 bytes. Therefore, the resulting Ethernet frame can be … 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.
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. WebJul 11, 2024 · All Ethernet subinterfaces always default to the 802.1Q VLAN encapsulation. However, you must explicitly define the VLAN identifier. Subinterface MTU The system inherits the subinterface maximum transmission unit (MTU)from the physical interface with an additional four bytes allowed for the 802.1Q VLAN tag. Native VLAN
802.1Q adds a 32-bit field between the source MAC address and the EtherType fields of the original frame. Under 802.1Q, the maximum frame size is extended from 1,518 bytes to 1,522 bytes.
