PRIORITY COMMANDS

IP Precedence and IP DSCP cannot both be enabled. Enabling one of these priority types will automatically disable the other type.

Example

The following example shows how to enable IP DSCP mapping globally:

Console(config)#map ip dscp

Console(config)#

map ip dscp (Interface Configuration)

Use this command to set IP DSCP priority (i.e., Differentiated Services Code Point priority). Use the no form to restore the default table.

Syntax

map ip dscp dscp-value cos cos-value no map ip dscp

dscp-value- 8-bit DSCP value. (Range: 0-255)

cos-value- Class-of-Service value (Range: 0-7)

Default Setting

The list below shows the default priority mapping. Note that all the DSCP values that are not specified are mapped to CoS value 0.
