So what does the tag includes? It includes a Media Access Control (MAC) address). Here, the trunking VLAN is used to mark the tag in the header of the frames to support reaching the destination. In terms of having multiple VLAN configured in a single port, the system has to understand and route the signals. It is more complicated when more than one VLAN is connected to a single port. But when multiple numbers of VLANs are connected in the network, it is necessary to ensure the singles are reaching the destination address. In the VLAN trunking, it is possible to extend into the entire network. Why Trunking is Important to Configure with VLAN? The above diagram shows all the traffic between the PCs in VLAN will be tagged to reach the destination address. The tagging mechanism is adding the tag to the frame header in the Ethernet interface. The default settings in the native VLAN, the switch is set to VLAN 1, and the settings allow the traffic send between all the port of more than one switches without any additional configuration. The traffic sends between the devices without adding anything (like tag) is called Native VLAN. Here the task is the two different methods: one is the native VLAN, and another one is the tagging mechanism. The primary mechanism is to trunking the devices that allow the traffic from more than one VLANs transported across a trunk in the modern switches. But, it will stop the traffic from particular VLANs from passing over the trunk by removing VLANs from a comprehensive list. Here the encapsulated method plays a vital role to manage or permit the traffic in the network.īy default, the trunk port access all the VLANs, and it will permit for trunking. The packet will reach the correct system using the tagging id within the multiple numbers of VLANs and switches. What are the details contained in the tag? it will include the sending id, port and switch details. Tagging would be done when sending the packets the tag will be inserted in the header of frames. The packet needs to send/deliver in an accurate destination from more than one number of VLANs, and it can be done using the tagging or ISL, it is also known as encapsulation. So that trunk port is configured here to send packets from more than one VLANs without having the traffic. The Ethernet can act as either an access port or a trunk port when it is sending packets, but it would not occur at the same time. Hence every single frame can be reached to designate VLAN. The trunk port marks the tag to the frame as 802.1 Q tag or the common technique Inter-Switch Link tags, also named ISL, when they moved between the switches. The trunk port will be carrying the signal traffic of all VLANs, which access to the specific switch is called Trunking.
