Usage
Information
Enter this command to honor all incoming 802.1p markings on incoming switched traffic on the
interface. 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.
On the C-Series and S-Series, all traffic is by default mapped to the same queue, Queue 0. If
you honor dot1p on ingress, you can create service classes based the queueing strategy using
the service-class dynamic dot1p command from INTERFACE mode. You may apply
this queuing strategy to all interfaces by entering this command from CONFIGURATION mode.
• All dot1p traffic is mapped to Queue 0 unless you enble the service-class
dynamic dot1p
command on an interface or globally.
• Layer 2 or Layer 3 service policies supercede dot1p service classes.
