Configuring Qos Parameters - Avaya G250 Administration

Configuring VoIP QoS
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.
Use the clear ip tcp header-compression command to clear TCP header
●
compression statistics either for all enabled interfaces or for a specific interface. To clear
TCP compression statistics for all enabled interfaces, do not enter an interface type and
number. Clearing the statistics does not cause renegotiation of parameters.
Use this command regardless of which compression method is employed.

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. For more information
about these commands, including parameters and default settings, see Avaya G250 and Avaya
G350 CLI Reference, 03-300437.
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 bearer command to provide the means to set up QoS parameters for
●
the VoIP bearer.
Note:
The parameters you define using the set qos bearer command may conflict
Note:
with the default QoS list (400). This causes the 801.2p for VoIP packets to differ
from settings configured in the QoS list. To avoid this problem, perform the
following steps:
1. Create a new QoS list.
2. In the new QoS list, either
Set the default IP rule composite operation to No Change, OR
●
Configure the DSCP map according to the QoS parameters you defined using the set
●
qos bearer command. For instructions on creating a QoS list, see
page 443.
Use the set qos signal command to provide the means to set up QoS parameters for
●
MGCP (H248) communication with the MGC.
