NOTE If you click Restore Defaults, the following mappings are applied to all interfaces.
Mapping DSCP Values to Queues
The priority of a packet arriving at an interface can be identified by the
Differentiated Service Code Point (DSCP) value in an IP packet header. The IP
DSCP field might contain any one of 64 values (0–63). You can use the DSCP to
Queue page to map these values to the four egress queues. Queue 1 has the
lowest priority and queue 4 has the highest priority.
DSCP mapping settings are applied globally to all ports.
To map DSCP values to queues:
STEP 1 Click Quality of Service > DSCP to Queue in the navigation window.
STEP 2 For each Ingress DSCP value, select a queue from the Output Queue list. Queue1
has the lowest priority, and queue 4 has the highest priority.
STEP 3 Click Apply. Your changes are saved to the Running Configuration.
