1Q devices that might exist on the segment. 1Q port is assigned an identifier value that is based on the native VLAN ID (VID) of the port. ) All untagged frames are assigned to the VLAN specified in this VID parameter. 1Q uses an internal tagging mechanism that inserts a four-byte tag field into the original Ethernet frame between the Source Address and Type or Length fields. 1Q alters the frame, the trunking device recomputes the frame check sequence (FCS) on the modified frame. It is the responsibility of the Ethernet switch to look at the four-byte tag field and determine where to deliver the frame.

In addition, with the phones in their own IP subnets and VLANs, network administrators can more easily identify and troubleshoot network problems and create and enforce QoS or security policies. With the voice VLAN feature, network administrators have all the advantages of the physical infrastructure convergence, while maintaining separate logical topologies for voice and data terminals. This configuration creates the most effective way to manage a multiservice network. VLAN Operation A Cisco Catalyst switch operates in a network similar to a traditional bridge.
