Configuring Subnets and VLANs

Configuring the Subnet

The subnet IP addresses and mask are assigned after the farm is Active. See Connecting Farm Elements for details about IP addresses and net mask assignments. Consider the following when using the Configure Subnet dialog box.

The following procedure describes configuration of the subnet by using the Editor screen.

ProcedureHow To Configure the Internal Subnet

Steps

  1. Double-click the Internal Subnet element.

    The Configure Subnet dialog box appears.

  2. Type the name of the Internal Subnet in the Name field.

  3. Type notes or comments into the Notes field.

  4. (Optional) Click the Add Host Name button to reserve a name for the IP.

  5. Type the DNS name in the field provided.

    This DNS name specifies the corresponding DNS prefix for each IP address that you reserve.

  6. Click OK to save your changes.

    The Configure Subnet dialog box is closed.

ProcedureHow To Configure the External Subnet

An External Subnet enables you to specify the number of externally facing IP addresses for the Internet or external network. The maximum number of IP addresses on the external subnet connection is 2048. The default number is 16 in the Control Center. When configuring an external subnet, you need to allocate a minimum of six IP addresses.

A farm usually has only one external subnet in its topology. In some cases, adding a second external subnet would offer a benefit to the farm, such as:

The following procedure describes how to use the Editor screen to configure an external subnet.

Steps

  1. Double-click the External Subnet element.

    The Configure External Subnet dialog box appears. The Subnet IP field displays the network address for this subnet. The Subnet IP is assigned when the farm is activated.

  2. Type the name in the Name field.

  3. In the Mask field, select a subnet mask.

    MASK is the net mask that is applied to elements on this external subnet.

  4. Type notes or comments in the Notes field.

  5. (Optional) Click the Add Host Name button to reserve a name for the IP.

  6. Type the DNS name in the field provided.

    This DNS name specifies the corresponding DNS prefix for each IP address that you reserve. SeeDNS Naming Conventions

  7. Click OK to save your changes.

    The Configure External Subnet dialog box is closed.

Configuring a VLAN Manually

By default, VLANs in a farm are configured automatically. However, you may choose to configure VLANs manually. You may perform the following management activities by using the Configure VLANs dialog box.

The names given to VLANs are used as an identifier to enable the configuration of a VLAN zones, such as a management VLAN, in the Control Center. The assigned names do not correlate to the actual VLAN names that are configured in the switch upon activation of the farm. Actual switch VLANs are allocated according to availability during the farm activation based on the VLAN zones specified in the Control Center.

Create VLAN types by associating multiple subnets with the same VLAN name. The VLAN names that you define in the Configure VLANs dialog box are displayed in the Configure Subnet dialog box for each associated subnet. Define the VLAN name list in the Configure VLANs dialog box and associate subnets with a VLAN name by using the Configure Subnet dialog box.

ProcedureHow To Add a VLAN Configuration

Steps

  1. In the Editor screen, choose Configure VLANs from the Edit menu.

    A message describing automatic VLAN configuration appears.

  2. Select Manually from the Configure VLANs drop-down list.

    The Configure VLANs dialog box appears.

  3. Select a VLAN from the Current VLANs list.

    The name, wire color, and included subnets display in the right pane.

  4. Add new VLAN information and click the Create VLAN button.

    For load balancing, change the subnet on which the data IP resides to be in the data VLAN.

  5. Click OK.

    The new VLAN information is applied and the Configure VLANs dialog box is closed.

    Note –

    If you add or delete a VLAN, you must update the appropriate subnet configuration to associate the subnet with the correct VLAN. If you delete a VLAN and do not associate the subnet configuration with another VLAN, an error message is printed.

ProcedureHow To Delete a VLAN Configuration

Steps

    A message describing automatic VLAN configuration appears.

  2. Select Manually from the Configure VLANs drop-down list.

    The Configure VLANs dialog box appears.

  3. Select a VLAN from the Current VLANs list.

    The name, wire color, and included subnets display in the right pane.

  4. To delete a VLAN, select the name in the Current VLANs list and click the Delete VLAN button.

  5. Click OK.

    The VLAN information is deleted and the Configure VLANs dialog box is closed.

    Note –

    If you add or delete a VLAN, you must update the appropriate subnet configuration to associate the subnet with the correct VLAN. If you delete a VLAN and do not associate the subnet configuration with another VLAN, an error message is printed.
