Software User Manual 12/10/09 MANAGING 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. A VLAN is a set of end stations and the switch ports that connect them. You may have many reasons for the logical division, such as department or project membership. The only physical requirement is that the end station and the port to which it is connected both belong to the same VLAN. 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. The VLAN folder contains links to the following features: • "VLAN Configuration" • "VLAN Status" • "VLAN Port Configuration" • "VLAN Port Summary" • "Reset VLAN Configuration" VLAN CONFIGURATION Use the VLAN Configuration page to define VLAN groups stored in the VLAN membership table. Your switch supports up to 3965 VLANs. VLAN 1 is the default VLAN of which all ports are members. To display the VLAN Configuration page, click LAN > L2 Features > VLAN > Configuration in the navigation tree. Page 186 Managing VLANs Document 34CSFP6XXUWS-SWUM100-D7
