Data Center Bridging in a Traffic Flow

The following figure shows how DCB handles a traffic flow on an interface.

QoS dot1p Traffic Classification and
Queue Assignment
The following section describes QoS dot1P traffic classification and assignments.
DCB supports PFC, ETS, and DCBx to handle converged Ethernet traffic that is assigned to an egress queue
according to the following QoS methods:
Honor dot1p You can honor dot1p priorities in ingress traffic at the port or global switch level (refer
to Default dot1p to Queue Mapping) using the service-class dynamic dot1p
command in INTERFACE configuration mode.
Layer 2 class maps You can use dot1p priorities to classify traffic in a class map and apply a service policy
to an ingress port to map traffic to egress queues.
