Configuring QoS

This section explains how to configure QoS. To generate QoS metrics, you need to enable QoS for the realm of the originating caller. The ingress realm determines whether QoS is turned on for a specific flow.

Note:

If you run with QoS turned on one side only and disabled on the other you lose the ability to measure latency through the use of RTCP timestamps.

QoS Configuration

To enable QoS:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type media-manager and press Enter.

   ORACLE(configure)# media-manager

3. Type realm-config and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.

   ORACLE(media-manager)# realm-config
   ORACLE(realm-config)#

4. qos-enable—Enable this parameter. The default value is disabled.

   Note:

   You do not have to reboot the SBC after enabling this parameter.

RTP Marker Bit Handling Configuration

To configure RTP marker bit handling:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type media-manager and press Enter to access the media-level configuration elements.

   ORACLE(configure)# media-manager
   ORACLE(media-manager)#

3. Type media-manager and press Enter to begin configuring media over TCP.

   ORACLE(media-manager)# media-manager
   ORACLE(media-manager-config)#

4. options — Set the options parameter by typing options, a Space, the option name use-rtp-marker-bit with a “plus” sign in front of it, and then press Enter.

   ORACLE(media-manager-config)# options +use-rtp-marker-bit

   If you type the option without the “plus” sign, you will overwrite any previously configured options. In order to append the new options to the media manager configuration’s options list, you must prepend the new option with a “plus” sign as shown in the previous example.

   Save and activate your configuration.
