A network subnet must be associated with a network site for the purposes of determining the geographic location of the host belonging to this subnet. You can use Lync Server Control Panel to configure subnets. From the Lync Server Control Panel, you can create, modify, or delete a network subnet. For details about deleting network subnets, see Deleting Network Subnets.

In most deployments of Microsoft Lync Server 2013 where call admission control (CAC) is implemented, there will typically be a large number of subnets. Because of this, it is often best to configure subnets from the Lync Server Management Shell. From there you can call New-CsNetworkSubnet in conjunction with the Windows PowerShell cmdlet Import-CSV. By using these cmdlets together, you can read in subnet settings from a comma-separated values (.csv) file and create multiple subnets at the same time. For examples of how to create subnets from a .csv file, see New-CsNetworkSubnet.

To create a network subnet

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Network Configuration and then click Subnet.

  4. On the Subnet page, click New.

  5. In New Subnet, enter a value in the Subnet ID field. This must be an IP address (for example, 174.11.12.0), and it must be the first address in the IP address range defined by the subnet.

  6. In the Mask field, enter a numeric value from 1 through 32.

    Note:
    This value is the bitmask that is to be applied to the subnet being created.

  7. In Network site ID, select the site to which this subnet belongs.

  8. (Optional) Type a value in the Description field to provide more information about this subnet that cannot be expressed by the name alone.

  9. Click Commit.

To modify a network subnet

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Network Configuration and then click Subnet.

  4. On the Subnet page, click the subnet that you want to modify.

  5. On the Edit menu, click Show details.

  6. On the Edit Subnet page, you can modify the bitmask, associated network site, or description. If you modify the bitmask, keep in mind that the Subnet ID must still be the first address in the IP address range defined by the subnet.

  7. Click Commit.
