Advanced IP Telephony Network Configuration

Although QPM’s IP Telephony wizard can configure many of the QoS requirements for an AVVID network, there are some potential configurations you might need to consider that are beyond the scope of the wizard. These topics describe some of these configuration issues:

Policing SoftPhone Traffic, page 7-19

Configuring QoS on ATM Connections, page 7-20

Configuring QoS on ATM to Frame Relay Connections, page 7-20

In addition to these topics, see the Cisco AVVID Network Infrastructure Enterprise Quality of Service Design Guide, which provides a blueprint for implementing the end-to-end Quality of Service (QoS).

This QoS is required for successful deployment of Cisco AVVID solutions in today's enterprise environment. It is located at:

Policing SoftPhone Traffic

On a Catalyst port that is connected to a PC running a Cisco IP SoftPhone application, the IP Telephony wizard marks all the VoIP traffic with DSCP value 46, and all the control traffic with DSCP 26. If PC users begin sending non-priority traffic using the VoIP UDP ports or the CTI TCP port, this non-priority traffic will receive the same quality of service from the network as VoIP traffic or VoIP control traffic.

You can configure policing on the inbound traffic of the Catalyst port to prevent the PC from flooding the queues for DSCP 46 traffic.

For example:

You can police VoIP traffic at a rate of 100kbps with a burst of 2kb.

You can police control traffic at 8kbps (configure 32kbs) with a burst of 8kb.

You should also set the markdown table on the device from DSCP 46 to 0, and DSCP 26 to 0.
