Mapping DSCP Values to Queues

Cisco Small Business SG200 Series 8-port Smart Switch 171

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.
