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.
NOTE:
Dell Networking does not recommend mapping all ingress traffic to a single queue when using PFC and ETS.
However, Dell Networking does recommend using Ingress traffic classification using the service-class dynamic
dot1p command (honor dot1p) on all DCB-enabled interfaces. If you use L2 class maps to map dot1p priority traffic to
egress queues, take into account the default dot1p-queue assignments in the following table and the maximum number of
two lossless queues supported on a port (refer to
Although Dell Networking OS allows you to change the default dot1p priority-queue assignments (refer to
Priorities for Incoming
mapping. If the configured DCB policy remains valid, the change in the dot1p-queue assignment is allowed.
Traffic), DCB policies applied to an interface may become invalid if you reconfigure dot1p-queue
