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
- 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.xmlNote: Substitute the actual Video MCU IP address
for the mcu-ip in the command.
- Save the retrieved network configuration information from
Step 1 in a media.xml file.
- Open the media.xml file for editing,
and complete these steps:
- 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>
- 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>
.
- Modify the IP_QOS section of the media.xml file
as follows:
- 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>
- Save all modifications to the media.xml file.
- 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
- Restart the Video MCU by entering this command:
