Configuring RTP statistics thresholds

Last Updated : Apr 03, 2020 |

About this task

Configure RTP statistics thresholds so that incrementation of QoS event counters coincides with real detectable bad QoS in your network. Optimal values are different for each network.

The Codec metrics, Codec loss and Codec RTT are useful for evaluating the actual user experience. The other metrics are useful for identifying network problems that contribute to QoS problems experienced by the user.

Procedure

  1. Run the rtp-stat thresholds command to set thresholds on QoS indicators.

    For example:

    Gxxx-001(super)# rtp-stat thresholds echo-return-loss 5
Done!

    With this example configuration, if echo-return-loss is sampled higher than 5 dB during an RTP session, the echo-return-loss event counter increments.

  2. Run the rtp-stat event-threshold command to set thresholds on QoS events.

    For example:

    Gxxx-001(super)# rtp-stat event-threshold echo-return-loss 2
Done!

    With this example configuration, if echo-return-loss is sampled over its threshold more than twice during an RTP session, the application considers the session to have QoS faults.
