To honor all incoming 802.1p markings on incoming switched traffic on the

interface, enter this command. By default, this facility is not enabled (that is, the

802.1p markings on incoming traffic are not honored).

You can apply this command on both physical interfaces and port channels. When

you set the service-class dynamic for a port channel, the physical interfaces

assigned to the port channel are automatically configured; you cannot assign the

service-class dynamic command to individual interfaces in a port channel.

each packet color-code. Also, you can specify the maximum drop rate percentage for yellow and green

profiles. The per-queue profile configured is applied to all the backplane ports.
