Chapter 7 Provisioning: Configuring QoS for IP Telephony

Configuring QoS Using the IP Telephony Wizard

You can also create voice policies without the wizard, using the voice policy templates supplied by QPM.

You assign the voice policies in the same way as you would data policies.

After you have completed the IP Telephony wizard, you can modify properties and policies of the voice

policies created by the voice wizard, to suit a specific network configuration.

Configuring QoS Using the IP Telephony Wizard

The IP Telephony wizard allows you to configure QoS for voice traffic on the network. The wizard

handles VoIP configuration in common IP telephony network topologies. It guides you through the steps

required to define your IP telephony network topology.

At each step, the wizard automatically creates the voice policies, that include the QoS properties and

traffic rules required at each network point (interface) where QoS is a concern. The wizard presents only

the interfaces on which the relevant QoS can be configured.

You need to select the network elements that require QoS configuration at each network point. The

wizard then automatically assigns the interfaces to the appropriate voice policies.

QPM allows you to import files which contain device role information about devices (see Removing

Devices, page 4-15). Device role information is used by the IP Telephony wizard during the selection of

interfaces to voice roles.

For example, for the wizard to select an Ethernet 10/100 port on the switch to an IP phone voice role,

the switch must be an access type switch (i.e., have an “access” device role). If the switch has a

“distribution” device role, QPM will not select it. If the device role information imported from a file is

not up-to-date, you can manually override it in the Device Properties page (see Viewing and Editing

Device Properties, page 4-10).

The wizard automatically creates voice policies in the current policy group. The policy group may also

contain previously created policies containing data traffic rules.

If required, you can change the current policy group when you start working with the wizard.

• If the required voice policies already exist in the policy group, the wizard uses them and assigns the

required interfaces to them.

• If a required voice policy does not exist in the policy group, the wizard creates a new one from the

relevant template.
