For more information about Option 3, which entails the Cisco IP SoftPhone
application, see the Cisco IP SoftPhone documentation library. The
Cisco IP SoftPhone application was developed to provide clients with a phone
that runs on software. This application can be installed on any PC that connects
to an IP telephony network.

The configurations described in this section use the model shown in Figure 3-2.
In this model, voice traffic is given a higher priority (CoS=5) than data traffic
(CoS=0). Hence, voice traffic is placed in a high-priority queue that gets serviced
first, and data traffic is placed in a low-priority queue that gets serviced later.
This section describes the following configuration schemes:
• Configuring Separate Voice and Data Subnets, page 3-4
• Configuring a Single Subnet for Voice and Data, page 3-7
For details on the commands used in the following configuration examples, refer
to Appendix A, “Command Reference for Voice VLAN.”
