FTOS places traffic marked with a priority in a queue based on Table 37-2. If you set a dot1p priority for a port-channel, all port-channel members are configured with the same value. You cannot assign a dot1p value to an individual interfaces in a port-channel. FTOS Behavior: The S-Series distributes eight dot1p priorities across four data queues. (Table 37-2).

To honor dot1p priorities on ingress traffic, use the service-class dynamic dot1p command from INTERFACE mode, as shown in Figure 37-3. You can configure this feature on physical interfaces and port-channels, but you cannot configure it on individual interfaces in a port channel. 666 | Quality of Service (QoS)
