Honor the incoming dot1p value
On the C-Series, if you know traffic originating from the phone is tagged with a dot1p value of 5, you
might make the associated queue a strict priority queue, as shown in the example below; on the C-Series,
FTOS maps dot1p priority 5 to queue 2.

Classifying VOIP traffic and applying QoS policies
Avoid congestion and give precedence to voice and signaling traffic by classifying traffic based on subnet
and using strict priority and bandwidth weights on egress, as outlined in the steps below.
Figure 39-5 depicts the topology and shows the configuration for a C-Series. The steps are the same on an
S-Series. The output example below the figure is a screenshot showing some of the steps and the resulting
running-config.
