Honoring the Incoming dot1p Value
If you know that trac 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 Trac and Applying QoS Policies
You can avoid congestion and give precedence to voice and signaling trac by classifying trac 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 conguration for
a C9000 system.
