13. CONFIGURING THE SWITCH An IEEE 802 1Q VLAN is a group of ports that can be located anywhere in the network but communicate as though they belong to the same physical segment VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections VLANs can be easily organized to reflect departmental groups such as Marketing or R amp D usage groups such as e mail or multicast groups used for multimedia applications such as videoconferencing VLANs provide greater network efficiency by reducing broadcast traffic and allow you to make network changes without having to update IP addresses or IP subnets VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN Up to 255 VLANs based on the IEEE 802 1Q standard e Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol Port overlapping allowing a port to participate in multiple VLANs End stations can belong to multiple VLANs e Passing traffic between VLAN aware and VLAN unawate devices e Priority tagging Assigning Ports to VLANs 2 62 Before enabling VLANs for the switch you must first assign each port to the VLAN group s in which it will participate By default all ports are assigned to VLAN 1 as untagged ports Add a port as a tagged port if you want it to carry tra
