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 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 can
support up to 1024 VLANs. VLAN 1 is created by default and is the default VLAN of
which all ports are members.
Manage the VLAN configuration on the switch
You can add, change, and delete VLANs, or reset the entire VLAN configuration on the
switch to defaults.
Add a VLAN You can add multiple VLANs to customize the switch for you network.
An internal VLAN is reserved by a port-based routing interface and invisible to the end
user. After an internal VLAN is allocated by the port-based routing interface, the VLAN
cannot be assigned to a routing VLAN interface.
To add a VLAN:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
