Command History This table includes the following release-specific history entries:

Usage Guidelines DSCP marking modifies the DSCP bits of the IPv4 header. IPinIP and GRE tunnels have at least two IP

headers. By default, DSCP marking is performed only on the external IP header. Use this command to

mark the DSCP bits of the internal IP header.

This command takes effect only when ipinip skip or gre skip is enabled (see the ip-tunnel ipinip skip

command or the ip-tunnel gre skip command).

Note DSCP marking should be enabled and configured through the SCA BB console. Refer to the section

“How to Manage DSCP Marker Values” in the Cisco Service Control Application for Broadband User

Guide for more information.

Caution DSCP marking can be configured only when no applications are loaded or the line card is shut down.

Authorization: admin

Examples The following example shows how to configure the Cisco SCE platform to perform DSCP marking on

the internal IP header of an IPinIP flow.

Note that you must access the root level to shut down the line card, even though the DSCP marking

command is at the admin level.
