Ports – QOS
The QOS decision tree chooses the highest priority Transmit Queue (TQ) of the following criteria:
Force High Priority (Port Based) TQ mapping, IEEE 8021.p TQ mapping, or DSCP TQ mapping.
The QOS tab under the Ports category displays the following details:
Port Number
This is the port index.
Port Name
This field displays the name of the port.
Include DSCP
This field displays the status of whether or not to include the RFC 2474 DSCP TOS (Type of Service) in the TQ
decision. When enabled, the DSCP TOS is included when evaluating traffic priority.

This field displays the status of whether or not to include the IEEE 802.1p COS (Class of Service) in the TQ decision.
When enabled, the IEEE 802.1p COS is included when evaluating traffic priority.
Force High Priority
This field displays the Force High Priority status. When enabled, the port based priority is included in the TQ decision
for all ports and all frames received on a port will use the default QOS priority for that port in the TQ decision.

This field displays the default QOS priority for that port. This is the IEEE 802.1p COS (Class of Service) assigned to all
untagged ingress frames, or all ingress frames if Force High Priority is enabled. The range is 0-7.
