Path-only node, has no configurable value.
There are two types of QoS Maps. The first type allows user to create QoS mapping to Traffic Class/color based on DSCP/Dot1p fields. These mappings are applied to inbound ports to classify the packets into different traffic classes/colors based on DSCP/Dot1p fields. Different traffic classes/colors can be associated with different SAI QoS objects (e.g., queues, wred) to provides differentiated services. User can also create map between traffic class to egress queue. ^ DCSP -> Traffic Class/Color ^ Dot1p -> Traffic Class/Color ^ Traffic Class -> egress queue The second type allows use to map incoming traffic to ingress buffer as well as set the priority field in the PFC frames. ^ Traffic Class to ingress buffer: This maps incoming traffic to ingress buffer.

PFC (priority-based Flow Control) is a kind of flow control based on Priority, which has the same principle as flow control. This series of switches use PFC to achieve the purpose of flow control, support global enable/de-enable PFC and specify one or some queues enable/de-enable PFC. This series of products supports setting up to two lossless queues. The default lossless queues are 3 and 4, so PFC is enabled by default for queue 3 and 4
