Trunking must be enabled when configuring VLANs on Cisco or other branded SWs. To set a specific port on the switch as Trunking, you can watch the video below and also subscribe to our YouTube channel to support us!

You can also check that the gigabitethernet 0/2 interface is set to Trunk after applying the show interfaces switchport command on Switch1. Thus, VLANs at different locations can communicate with each other using the encapsulation method on the Ports.Īfter applying the show interfaces switchport command on Switch0, you can check that the gigabitethernet 0/1 interface is set to Trunk. If Trunk has not configured in this scenario, the computers in VLAN5 would not be able to communicate with each other! You can see that the ping was successful from the image below. Switch# conf tįrom the PC1 command prompt in the Packet Tracer workspace, ping PC2 that is a member of VLAN5. Now click on the other Switch1 and configure the interface plugged into Switch0 as Trunk.
You must enable the Trunk feature on each device port to transmit information of different VLANs between switches. Switch(config)# interface gigabitethernet 0/1 In the window that opens, click the CLI tab, and then perform the following commands. After creating the VLAN, click Switch0 to transfer the VLAN ID between the Switches. Perform VLAN creation on Cisco Switch before enabling this protocol. To activate Trunk and examine its logic, open Packet Tracer and create a network topology as shown in the following illustration. How to Configure Trunk Port on Cisco Switch Adds a 26-byte header and a 4-byte trailer into the frame. ISL (Inter-Switch Link) = Specific to Cisco only. If you are using Cisco Switch devices in a network environment, you can set the encapsulation status to ISL.Ĩ02.1Q encapsulation has been developed to ensure the compatibility of all Switches.Ĩ02.1Q = Adds a 4-byte tag after the source address in the frame. The encapsulation method is available only for Cisco products.
