Within a call admission control (CAC) configuration, you can create network inter-site policies that define bandwidth limitations between sites that are directly linked. When network sites share a direct link, bandwidth limitations for audio and video connections can be defined between those two sites. You cannot use the Lync Server Control Panel to configure network site policies, this can be done only by using cmdlets from the Lync Server Management Shell. You can create, modify, and remove a network site link (also known as a network inter-site policy) from the Lync Server Management Shell.

To create a network site link

  1. Log on to the computer where Lync Server Management Shell is installed as a member of the RTCUniversalServerAdmins group or with the necessary user rights as described in Delegate Setup Permissions.

  2. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

  3. From the command prompt, type the following command, substituting values that are valid for your configuration:

    Copy Code 
    New-CsNetworkInterSitePolicy -Identity Reno_Portland -NetworkSiteID1 Reno -NetworkSiteID2 Portland -BWPolicyProfileID LowBWLimits

    This example creates a new network site link named Reno_Portland that sets bandwidth limitations between the Reno and Portland network sites. The network sites and the bandwidth policy profile must already exist before running this command.

For detailed parameter descriptions, see New-CsNetworkInterSitePolicy in the Lync Server Management Shell documentation. To retrieve a list of bandwidth policy profiles that can be applied to the network site link, call the Get-CsNetworkBandwidthPolicyProfile cmdlet. For details, see Get-CsNetworkBandwidthPolicyProfile in the Lync Server Management Shell documentation.

To modify a network site link

  1. Log on to the computer where Lync Server Management Shell is installed as a member of the RTCUniversalServerAdmins group or with the necessary user rights as described in Delegate Setup Permissions.

  2. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

  3. Use the Set-CsNetworkInterSitePolicy cmdlet to modify the properties of a given network site link. You can modify either (or both) or the connected sites, and you can modify the bandwidth policy profile associated with the link. Here is an example of modifying the bandwidth policy profile of a site link named Reno_Portland:

    Copy Code 
    Set-CsNetworkInterSitePolicy -Identity Reno_Portland -BWPolicyProfileID HighBWLimits

For detailed parameter descriptions, see Set-CsNetworkInterSitePolicy in the Lync Server Management Shell documentation.

To delete a network site link

  1. Log on to the computer where Lync Server Management Shell is installed as a member of the RTCUniversalServerAdmins group or with the necessary user rights as described in Delegate Setup Permissions.

  2. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

  3. Use the Remove-CsNetworkInterSitePolicy cmdlet to remove a network site link. The following example deletes the Reno_Portland network site link:

    Copy Code 
    Remove-CsNetworkInterSitePolicy -Identity Reno_Portland

For detailed parameter descriptions, see Remove-CsNetworkInterSitePolicy in the Lync Server Management Shell documentation.
