Configuring QoS settings on the Sametime Video MCU

Configure QoS (quality of service) settings on the IBM® Sametime® Video MCU by modifying the network configuration settings saved in a media.xml file.

About this task

Perform this procedure on the Sametime Video MCU.

Procedure

  1. Retrieve the Sametime Video MCU's current network configuration by entering this command:
    curl -k -H "If-None-Match: -1" -H "Content-Type: application/vnd.plcm.dummy+xml" -u SUPPORT:SUPPORT https://mcu-ip/plcm/mcu/api/1.0/system/service/media -o media.xml
    Note: Substitute the actual Video MCU IP address for the mcu-ip in the command.
  2. Save the retrieved network configuration information from Step 1 in a media.xml file.
  3. Open the media.xml file for editing, and complete these steps:
    1. Remove the first 5 lines from the media.xml file. For example, remove these five lines:
      <IP_SERVICE_LIST>
      <OBJ_TOKEN>1</OBJ_TOKEN>
      <CHANGED>true</CHANGED>
      <DEFAULT_NAME>Default IP Service</DEFAULT_NAME>
      <DEFAULT_SIP_NAME>Default IP Service</DEFAULT_SIP_NAME>
    2. Remove the last line from the media.xml file. For example, remove this line:
      </IP_SERVICE_LIST>

      The first line and last line of the media.xml file should now be <IP_SERVICE>.

  4. Modify the IP_QOS section of the media.xml file as follows:
    1. Set <QOS_IP_AUDIO>value</QOS_IP_AUDIO> and <QOS_IP_VIDEO>value</QOS_IP_VIDEO> to the desired value. For example:
      <IP_QOS>
      <QOS_ACTION>enabled</QOS_ACTION>
      <QOS_DIFF_SERV>diffserv</QOS_DIFF_SERV>
      <QOS_IP_AUDIO>20</QOS_IP_AUDIO>
      <QOS_IP_VIDEO>30</QOS_IP_VIDEO>
      <QOS_TOS>none</QOS_TOS>
      </IP_QOS>
  5. Save all modifications to the media.xml file.
  6. From the directory to which you originally saved the media.xml file, send the modified media.xml file back to the Video MCU by entering this command:

    curl -k -H "If-None-Match: -1" -H "Content-Type: application/vnd.plcm.dummy+xml" -u SUPPORT:SUPPORT -X PUT -d @media.xml https://mcu-ip/plcm/mcu/api/1.0/system/service/media

  7. Restart the Video MCU by entering this command:

    service soft_mcu restart
