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
), DCB policies applied to an interface may become invalid if you reconfigure dot1p-queue mapping. If the configured
DCB policy remains valid, the change in the dot1p-queue assignment is allowed.
NOTE:
Although, each port on the S4810, S4820T, and S5000 devices support 8 QoS queues, you can configure only 4 QoS
queues (0-3) to manage data traffic. The remaining 4 queues (4-7) are reserved for control traffic.
