QoS dot1p Traffic Classification and Queue
Assignment
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
dot1p priorities in ingress traffic are used at the port or global switch level.
Layer 2 class
maps
dot1p priorities are used 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
