Configuring Qos Parameters - Avaya G250 Administration

Configuring VoIP QoS

Configuring QoS parameters

The G250/G350 uses MGCP (H248) 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 where 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 (H248) communication with the MGC.
Use the voip-queue-delay command to set the maximum queue delay for which to
●
estimate the high priority queue size necessary to meet the queuing delay for a specific
VoIP codec. To determine the queue size you currently have, use the show queueing
command.
Use the show qos 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). In particular, the signal 802.1 priority and the bearer 802.1 priority
are not applicable for the TGM550.
For more information about these commands, including parameters and default settings, see
