Enabling CAC

After adding all the relevant network information in the previous steps, it is now time to enable CAC.

Getting ready

Enabling CAC must be done for the sites in Topology Builder and globally in CSCP or PowerShell.

How to do it...

The following are the six steps to enable CAC in sites:

  1. Start Topology Builder with an account that has the RTCUniversalServerAdmins rights and save the topology file when prompted.
  2. For each site in the topology:
    1. Right-click on the site node.
    2. Select Edit properties.
    3. Scroll down to the Call admission control setting option.
    4. Select the Enable call admission control checkbox, as shown in the following screenshot:
      How to do it...
    5. If there is more than one pool in the site, select a pool (in a single pool site, the pool should be selected automatically).

      Note

      It is common to add this feature to the first pool in each site, but it does not have to be. After we select a pool for this job, the CAC service has to be installed on the selected pool.

    6. Click on OK.
  3. Publish the topology (and make note of the to-do list).
  4. Initiate the replication (Invoke-CsManagementStoreReplication).
  5. Wait for the replication to complete.
  6. Complete the to-do list from the publishing wizard.

Proceed with the following steps to enable CAC globally:

  1. Launch the Lync Server Control Panel with a CSAdministrator account, and navigate to the Global option under the Network Configuration section.
  2. Simply select Enable call admission control, as shown in the following screenshot:

  3. Select Commit.

    Note

    We'll discuss Media Bypass in a different section.

There's more...

There are a lot of site settings that we can manage through the Set-CsSite command, but Enable call admission control is not one of them. This task has to be completed in Topology Builder.

The network configuration portion, however, can easily be performed through PowerShellin the following two steps:

  1. Launch PowerShell in an elevated prompt.
  2. Type the following command:
    Set-CsNetworkConfiguration -EnableBandwidthPolicyCheck 1

    Note

    As an addition to enabling CAC, it might be a good idea to enable logging as well. This can be done with the following command:

    Set-CsBandwidthPolicyServiceConfiguration -EnableLogging $true – LogCleanUpInterval 10.00:00:00 -MaxLogFileSizeMb 10 –MaxTokenLifetime 12:00:00

    Consider how much data to keep, and adjust the parameters of this command as needed.

The previous command will enable logging and store data in the fileshare under the application server's PDP directory, for example, \fileserver.mydomain.comShare1-ApplicationServer-1AppServerFilesPDP. These files can be viewed in the Lync Resource Tool Kit Bandwidth Utilization Analyzer for further analysis.
