Configuring VLANsFigure 10: VLAN Example.SalesMarketingEngineeringSalesMarketingEngineeringVLAN taggingVLAN Tagging is a method of controlling the distribution of information on the network. Theports on devices supporting VLAN Tagging are configured with the following parameters:●Port VLAN ID● Tagging ModeThe Port VLAN ID is the number of the VLAN to which the port is assigned.Note:Note: You need to create a VLAN with the set vlan command before you can assignit to a port. You can also create a VLAN by using the interface vlancommand, followed by the number of the VLAN (e.g., type interface vlan 2to create VLAN 2).Untagged frames and frames tagged with VLAN 0 entering the port are assigned the port’sVLAN ID. Tagged frames are unaffected by the port’s VLAN ID.The Tagging Mode determines the behavior of the port that processes outgoing frames:● If Tagging Mode is set to Clear, the port transmits frames that belong to the port’s VLANtable. These frames leave the device untagged.●If Tagging Mode is set to IEEE-802.1Q, all frames keep their tags when they leave thedevice. Frames that enter the switch without a VLAN tag are tagged with the VLAN ID ofthe port they entered through.Issue 3 January 2005 133
