As part of call admission control (CAC), a bandwidth policy is used to define bandwidth limitations for certain modalities. In Microsoft Lync Server 2010, only audio and video modalities can be assigned bandwidth limitations. You can set overall bandwidth limitations and session limitations. You can use the Lync Server Control Panel to create or modify a container profile for these policies. Each bandwidth policy profile can be associated with one or more network sites.

To create a new bandwidth policy profile

  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 Policy Profile.

  4. On the Policy Profile page, click New.

  5. In New Bandwidth Policy Profile, type a name in the Name field. This name must be unique among all bandwidth policy profiles.

  6. In the Audio limit field, type a numeric value. This value is the maximum amount of bandwidth to allocate for all audio connections, expressed in kbps.

  7. Enter a numeric value in the Audio session limit field. This value is the maximum amount of bandwidth to allocate for an individual audio connection, expressed in kbps. This value must be 40 or higher.

  8. Enter a numeric value in the Video limit field. This value is the maximum amount of bandwidth to allocate for all video connections, expressed in kbps.

  9. Enter a numeric value in the Video session limit field. This value is the maximum amount of bandwidth to allocate for an individual video connection, expressed in kbps. This value must be 100 or higher.

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

  11. Click Commit.

    Note:
    Creating a new bandwidth policy profile does not automatically enforce bandwidth restrictions. You must first associate the policy profile with a site. For details about how to associate a policy profile with a site, see Configuring Network Sites.

To modify a bandwidth policy profile

  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 Policy Profile.

  4. On the Policy Profile page, click the bandwidth policy profile that you want to modify.

  5. On the Edit menu, click Show details.

  6. On the Edit Bandwidth Policy Profile page, modify the fields as necessary (for details, see the "To create a bandwidth policy profile" section earlier in this topic).

  7. Click Commit.

    Note:
    When you modify the bandwidth policy profile, it will immediately update the bandwidth limitations of all network sites associated with this bandwidth policy profile.

To delete a bandwidth policy profile

  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 Policy Profile.

  4. On the Policy Profile page, click the bandwidth policy profile that you want to delete.

    Note:
    You can delete more than one profile at a time. To do this, press CTRL and select multiple profiles while holding down the CTRL key. Or, to select all profiles, click Select all on the Edit menu.
  5. On the Edit menu, click Delete.

    Warning:
    You cannot delete a bandwidth policy profile that is associated with a network site. You must first remove the association with the network site before you can delete the profile. For details about how to modify the network site, see Configuring Network Sites.
