DSCP Template Configuration Mode Commands

The DSCP Template Configuration Mode provides the commands to configure DSCP marking for control packets and data packets for Gb over IP. Any number of DSCP templates can be generated in the SGSN Global configuration mode and then a template can be associated with one or more GPRS Services via the commands in the GPRS Service configuration mode.

The prompt for this mode appears as:
[local]<hostname>(config-dscp-template-<template_name>)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

default

Resets the quality of service (QoS) DSCP setting to the ‘BE’ (best effort) default value.

DSCP marking option

Usage:

This command configures the QoS DSCP marking type for downlink control packets.

Related commands for SGSN:
  • To create/delete a DSCP template, use the dscp-template in the SGSN Global configuration mode (see the SGSN Global Configuration Mode Commands section).
  • To associated a specpific DSCP template with a specific GPRS service configuration, use the associate-dscp-template downlink documented in the GPRS Service Configuration Mode Commands section.
  • To check values configured for DSCP templates, use the show sgsn-mode command documented in the Exec Mode Commands section.
Related commands for HNB-GW:
  • To create/delete a DSCP template, use the dscp-template in the SGSN Global Configuration Mode.
  • To associated a specpific DSCP template with a system for a PSP instance in SS7 routing domain, use associate-dscp-template downlink documented in the SGSN PSP Configuration Mode Commands section.

Example:
Use a command similar to the following to set expedited forward per-hop behavior for the downlink control packets:
control-packet qos-dscp ef
Use the following command to reset the default best effort per-hop behavior: 
default control-packet

Usage:

This command configures the QoS DSCP marking type for downlink data packets. DSCP levels indicate how packets are to be handled

Related commands:
  • To create/delete a DSCP template, use the dscp-template in the SGSN Global configuration mode (see the SGSN Global Configuration Mode Commands section).
  • To associated a specpific DSCP template with a specific GPRS service configuration, use the associate-dscp-template downlink documented in the GPRS Service Configuration Mode Commands section.
  • To check values configured for DSCP templates, use the show sgsn-mode command documented in the Exec Mode Commands section.

Example:
Use a command similar to the following to set expedited forward per-hop behavior for the downlink control packets:
