STEP 1 Click Configuration > Quality of Service > Basic QoS
STEP 2 Select the Trust Mode while the device is in Basic mode The Trust
mode determines the queue to which the packet is assigned:
•
CoS/802 1p—Traffic is mapped to queues based on the VPT field in the
VLAN tag, or based on the per-port default CoS/802 1p value (if there is
no VLAN tag on the incoming packet), the actual mapping of the VPT to
queue can be configured in the mapping CoS/802 1p to Queue page
•
DSCP—All IP traffic is mapped to queues based on the DSCP field in the
IP header The actual mapping of the DSCP to queue can be configured in
the DSCP to Queue page If traffic is not IP traffic, it is mapped to the best
effort queue
•
CoS/802 1p-DSCP—All IP traffic is mapped to queues based on the values
in their DSCP field All non IP traffic is mapped to queues based on the
their CoS/802 1p value
