DSCP priority values are mapped to default Class of Service values according to recommendations in the IEEE 802.1p standard, and then mapped to the queue defaults.

Mapping specific values for DSCP is implemented as an interface configuration command, but any changes apply to all interfaces on the switch.

Example

The following example shows how to map IP DSCP value 1 to COS value 0:

Console(config)#interface ethernet SNP5

Console(config-if)#map ip dscp 1 cos 0

Console(config-if)#

4.3.15.10show map ip precedence

Use this command to show the IP precedence priority map.
