M4300 Intelligent Edge Series Fully Managed Stackable Switches Configure 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 is assigned 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 can omit the tag, or the VLAN portion of the tag, in which case the first switch port to receive the packet can either reject it or insert a tag using its default VLAN ID. A given port can handle traffic for more than one VLAN, but it can support only one default VLAN ID. You can define VLAN groups stored in the VLAN membership table. Each switch in the M4300 Series and M4300-96X family supports up to 1024 VLANs. VLAN 1 is created by default and is the default VLAN of which all ports are members. Configure Basic VLAN Settings The internal VLAN is reserved by a port-based routing interface and invisible to the end user. Once these internal VLANs are allocated by the port-based routing interface, they cannot be assigned to a routing VLAN interface. To configure internal VLAN settings: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login window opens. 3. Enter admin as the user name, enter your local device password, and click the Login button. The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in. The System Information page displays.
