VLAN Configuration

VLANs provide a method for segmenting a network into related groups, improving the efficiency of traffic flow, and limiting the propagation of multicast and broadcast messages. On an individual switch, traffic between VLANs is blocked unless the VLANs are connected by a router, increasing security.

A VLAN is a group of ports designated by the switch as belonging to the same broadcast domain. That is, all ports carrying traffic for a particular subnet address would belong to the same VLAN. Using a VLAN, you can group users by logical function instead of physical location. This helps to control bandwidth usage by allowing you to group high-bandwidth users on low-traffic segments and to organize users from different LAN segments according to their need for common resources. Beginning with release C.06.01 of the switch software (operating system, or "OS") you can use the switch's console interface to configure up to 30 port-based, IEEE 802.1Q-compliant VLANs. (Earlier releases of the OS allow up to eight port-based, IEEE 802.1Q-compliant VLANs.) This enables you to use the same port for two or more VLANs and still allows interoperation with older switches that require a separate port for each VLAN. For more information:

  2. If you want a detailed description of how to use and configure VLANs with this switch product, refer to the Management and Configuration Guide (shipped with the switch and also available on HP's Network City website at http://www.hp.com/go/procurve).

Devices supported:

Note: If a switch is a Commander, the stack options will appear at the top of the page. 

Note: When multiple VLANs exist on a switch, only one VLAN can be untagged for each port. When you first add a VLAN to a switch, the default setting on that VLAN is No for all ports, indicating that no ports are members of this VLAN. Using the Web browser interface, if you then reconfigure a port to Untagged for a new VLAN while there is an Untagged setting on another VLAN for the same port, the switch automatically reconfigures the other VLAN setting to No. For example, if you configure Port A1 as Untagged for the 2nd VLAN, then the switch automatically reconfigures DEFAULT_VLAN for port A1 to No

How To...

Access the VLAN Configuration Page from HP TopTools

  1. Click on the Devices button in the navigation frame.
  2. Select Device Types from the menu.
  3. Select Networking Devices.
  4. Double-click on the device in the device list.
  5. In the Status page click on the Configuration tab. The device's configuration page displays.
  6. Select the VLAN Configuration button. The VLAN Configuration page displays.

Access the VLAN Configuration page using the Web Agent

  1. Click on the Configuration tab.
  2. Select the VLAN Configuration button. The VLAN Configuration page displays.

Enable VLANs

To enable VLANs, click the VLANs Enabled radio button at the bottom of the table in the VLAN Configuration page. 

If you change the current setting, you need to reboot the switch to effect the change. You will be prompted for the reboot.

Add a VLAN

  1. Click on the Add/Remove VLANs button at the bottom of the table in the VLAN Configuration page. The Add/Remove VLAN page displays. 
  2. Enter a name for the new VLAN in VLAN Name field below the Current VLAN Definitions list box.
  3. Enter the 802.1Q ID (an unused number between 1 and 4094) in the field labeled 802.1Q VLAN ID.
  4. Click on the Add VLAN button. The VLAN appears in the Current VLAN Definitions box. 

Rename a VLAN

  1. Click on the Add/Remove VLANs button at the bottom of the table in the VLAN Configuration page. The Add/Remove VLAN page displays.
  2. Select the VLAN to be renamed from the Current VLAN Definitions list. 
  3. Enter a name for the selected VLAN in the New VLAN Name field.
  4. Click on the Rename Selected VLAN button to save the new name.

Remove a VLAN

  1. Click on the Add/Remove VLANs button at the bottom of the table in the VLAN Configuration page. The Add/Remove VLAN page displays.
  2. Select the VLAN to remove from the Current VLANS box.
  3. Click on the Remove Selected VLAN button.
  4. Confirm removal of the VLAN.

Modify Port VLAN Configuration

To modify ports in a VLAN:

  1. In the VLAN table, click on the Modify button for the VLAN whose ports you want to modify. The  Modify Port VLAN Configuration page displays.
  2. Select the port to be modified.
  3. Select the Mode, for example, Tagged.  
  4. Click on the Apply button. 

The modes are:
