The following example shows how to enable IP precedence mapping
globally:
Console(config)#map ip precedence
Console(config)#
This command sets IP DSCP priority (i.e., Differentiated Services Code
Point priority). Use the no form to restore the default table.

The DSCP default values are defined in the following table. Note that all the
DSCP values that are not specified are mapped to CoS value 0.

◆ The precedence for priority mapping is IP Port, IP Precedence or IP
DSCP, and default switchport priority.
DSCP priority values are mapped to default Class of Service values
◆
according to recommendations in the IEEE 802.1p standard, and then
subsequently mapped to the eight hardware priority queues.
This command sets the IP DSCP priority for all interfaces.
