2. Trunk ports will not carry traffic for VLANs that are not configured in a switch For example if the user wants to carry traffic for all the VLANs from 1 to 1024 in a trunk port VLANs 1 to 1024 need to be created in the switch using the vlan command A switch adds the VLAN tag header to all packets sent out on the trunk port except for native VLAN traffic Supermicro switches support only IEEE 802 1Q encapsulation for VLAN tag headers When a packet is received on a trunk port the switch identifies the VLAN for the received packet from the packet s VLAN tag header If the received packet did not have a VLAN identifier and the packet did not match any MAC or protocol VLAN the port PVID is used to determine the VLAN for all untagged and priority tagged packets that are received A native VLAN identifier is configured as a PVID for the trunk ports If the user has not configured a native VLAN the default VLAN 1 will be used as PVID for the trunk ports Follow the steps below to configure any port as a trunk port Step Command Description Step 1 configure terminal Enters the configuration mode Supermicro L2 L3 Switches Configuration Guide e VLAN Configuration Guide Step 2 interface lt interface type gt lt interface id gt Enters the interface mode or interface range lt interface type gt lt interface id gt interface type may be any of the following gigabitethernet gi extreme etherne
