Mapping dot1p Values to Service Queues
All trac 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 in Honoring dot1p Values on Ingress Packets. You
may apply this queuing strategy globally by entering the following command from CONFIGURATION mode.
• All dot1p trac is mapped to Queue 0 unless you enable service-class dynamic dot1p on an interface or globally.
• Layer 2 or Layer 3 service policies supersede dot1p service classes.
• Create service classes.
