E XAMPLE
The following example shows how to enable IP precedence mapping
globally:
Console(config)#map ip precedence
Console(config)#
map ip dscp
(Interface
Configuration)
This command sets IP DSCP priority (i.e., Differentiated Services Code
Point priority). Use the no form to restore the default table.
S YNTAX
map ip dscp dscp-value cos cos-value
no map ip dscp
dscp-value - 8-bit DSCP value. (Range: 0-63)
cos-value - Class-of-Service value (Range: 0-7)
D EFAULT S ETTING
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.
