Keywords:
QoS implementation allows for the propagation of RTCP packets received from endpoints to Avaya VoIP Monitoring Manager (VMM). If there are no RTCP statistics available, ensure that QoS monitoring is enabled on System Manager.
Important:
Troubleshooting QoS related problems may require stopping and starting the tps service, which might have an impact on endpoint registration and call handling. For more information, see Maintenance commands.
Avaya recommends that you stop and start the tps service during the maintenance period to minimize endpoint registration and call handling problems.
  1. On the System Manager web console, click ElementsAvaya Breeze®Configuration.
  2. Click Attributes.
  3. Navigate to the IP Telephony Node / Quality of Service (QoS) area and do the following:
    1. In the VoIP Monitoring Enabled field, in Effective Value, click Yes.
    2. Ensure that the VoIP Monitoring Reporting Interval field is not set to zero.
    3. In the VoIP Monitoring Manager IP address field, in Effective Value, type the VMM IP address.
    4. In the VoIP Monitoring Manager Port field, in Effective Value, type the VMM port number.
      ADDITIONAL INFORMATION:
      The default port is 5005.
  4. Log in to Avaya Breeze® platform server by using SSH and the appropriate credentials.
  5. Open the /opt/Avaya/da/shared/config/mamcfg.xml file.
    ADDITIONAL INFORMATION:
    Ensure the QoS section contains the same SAMPLEPERIOD value as configured for reporting interval on System Manager.
  6. If there are problems in the mamcfg.xml file, stop and start the tps service by using the following commands:
    ADDITIONAL INFORMATION:
    dasrvstart stop tps
    dasrvstart start tps
  7. Verify that the omm process is running by using the dasrvstart status omm command.
  8. Set the log level to DEBUG for tVTM by using the syslogLevelSet tps tVTM DEBUG command to verify that RTCP statistics are sent from the TPS side.
  9. Verify that the following log is printed periodically:
    ADDITIONAL INFORMATION:
    RTCP statistics is generated for set <IP address of the phone>
