Configuring Qos Parameters - Avaya G250 Administration Manual

Configuring VoIP QoS
Use the show ip tcp header-compression command to display the TCP header
●
compression statistics for a specific interface. If no interface is specified, statistics for all
interfaces are displayed. Use this command regardless of which compression method is
employed.
Use the clear ip rtp header-compression command to clear RTP header
●
compression statistics either for all enabled interfaces or for a specific interface. To clear
RTP compression statistics for all enabled interfaces, do not enter an interface type and
number. Clearing the statistics does not cause renegotiation of parameters.

Configuring QoS parameters

The G250/G350 uses MGCP (H.248) protocol for call signalling and call routing information.
Use the following commands to configure QoS for signalling and VoIP traffic.
Use the set qos control command to define the source for QoS control parameters.
●
The source can be either local, in which case the user configures the values locally on
the G250/G350, or remote, in which case the values are obtained from the G250/G350's
registered MGC.
Use the set qos signal command to provide the means to set up QoS parameters for
●
MGCP (H.248) communication with the MGC.
Use the show qos-rtcp command to display the local and downloaded QoS
●
parameters.
Use the set qos bearer command to provide the means to set up QoS parameters for
●
the VoIP bearer.
The parameters you define using the set qos bearer command may conflict with the
default QoS list (400).
For more information about these commands, including parameters and default settings, see
Avaya G250 and Avaya G350 CLI Reference, 03-300437.
