Honoring the Incoming dot1p Value
If you know that trac originating from the phone is tagged with a dot1p value of 5, you can make the associated queue a strict-priority
queue, as shown in the following example.

Classifying VoIP Trac and Applying QoS Policies
You can avoid congestion and give precedence to voice and signaling trac by classifying trac based on the subnet and using strict
priority and bandwidth weights on egress, as outlined in the following steps. The following gure depicts the topology and conguration for
a C9000 system.
