GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches VLANs Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast, and like a router, it partitions the network into logical segments, which provides better administration, security and management of multicast traffic. By default, all ports on the switch are in the same broadcast domain. VLANs electronically separate ports on the same switch into separate broadcast domains so that broadcast packets are not sent to all the ports on a single switch. When you use a VLAN, users can be grouped by logical function instead of physical location. Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. An end station may omit the tag, or the VLAN portion of the tag, in which case the first switch port to receive the packet may either reject it or insert a tag using its default VLAN ID. A given port may handle traffic for more than one VLAN, but it can only support one default VLAN ID. From the VLAN link, you can access the following pages: • VLAN Configuration on page 110 • VLAN Membership Configuration on page 112 • Port VLAN ID Configuration on page 113 • MAC Based VLAN on page 114 • Protocol Based VLAN Group Configuration on page 115 • Protocol Based VLAN Group Membership on page 116 VLAN Configuration Use the VLAN Configuration page to define VLAN groups stored in the VLAN membership table. The GS728TS, GS728TPS, GS752TS, and GS752TPS each support up to 256 VLANs. Three VLANs are created by default: • VLAN 1 is the default VLAN of which all ports are members. • VLAN 2 is for voice traffic. • VLAN 3 is for Auto-Video traffic.
