Create Network Region Links

 

Topic Last Modified: 2011-01-27

Regions within a network are linked through physical WAN connectivity. A network region link creates a link between two regions configured for call admission control (CAC) and sets the bandwidth limitations on audio and video traffic between these regions.

For details about working with network region links, see the Lync Server Management Shell documentation for the following cmdlets:

  • New-CsNetworkRegionLink
  • Get-CsNetworkRegionLink
  • Set-CsNetworkRegionLink
  • Remove-CsNetworkRegionLink

The example topology has a link between the North America and APAC regions, and a link between the EMEA and APAC regions. Each of these region links is constrained by WAN bandwidth, as described in Region Link Bandwidth Information table in the Example: Gathering the Required Information for Call Admission Control section of the Planning documentation.

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

  2. Run the New-CsNetworkRegionLink cmdlet to create the region links and apply appropriate bandwidth policy profiles. For example, run:

    New-CsNetworkRegionLink -NetworkRegionLinkID NA-EMEA-LINK -NetworkRegionID1 NorthAmerica -NetworkRegionID2 EMEA -BWPolicyProfileID 50Mb_Link
    
    New-CsNetworkRegionLink -NetworkRegionLinkID EMEA-APAC-LINK -NetworkRegionID1 EMEA -NetworkRegionID2 APAC -BWPolicyProfileID 25Mb_Link
    

  1. 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.

  2. In the left navigation bar, click Network Configuration.

  3. Click the Region Link navigation button.

  4. Click New.

  5. On the New Region Link page, click Name and then type a name for the network region link.

  6. Click Network Region #1, and then click the network region in the list that you want to link to Network Region #2.

  7. Click Network Region #2, and then click a network region in the list that you want to link to Network Region #1.

  8. Optionally, click Bandwidth policy, and then select the bandwidth policy profile that you want to apply to the network region link.

    noteNote:
    Apply a bandwidth policy only if the network region link is bandwidth-constrained and you want to use CAC to control media traffic on that link.
  9. Click Commit.

  10. To finish creating network region links for your topology, repeat steps 4 through 9 with settings for other regions.
