Legacy QoS Command Deprecation

Last Updated: December 9, 2011

In Cisco IOS XE Release 2.6, to streamline Cisco IOS XE quality of service (QoS), certain commands have been hidden. Although these commands are available, the command-line interface (CLI) interactive help does not display them. This means that if you attempt to view a hidden command by entering a question mark (?) at the command line, the command does not appear. However, if you know the command syntax, you can enter it (the system accepts the command and returns a message stating that it is deprecated).

The functionality provided by these hidden commands has been replaced by similar functionality provided via the modular QoS CLI (MQC). The MQC is a set of a platform-independent commands for configuring QoS on Cisco platforms. This means that you should now provision QoS by defining traffic classes, creating traffic policies containing those classes, and attaching those policies to the desired interfaces.

In Cisco IOS XE Release 3.2S, these commands have been removed. This means that you must use the appropriate replacement MQC commands.

This document lists the hidden or removed commands and their replacement commands.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Information About Legacy QoS Command Deprecation

QoS Features Applied Using the MQC

The MQC structure lets you define a traffic class (also called a class map), create a traffic policy (also called a policy map), and attach the traffic policy to an interface. This comprises the following three high-level steps.

  1. Define a traffic class by using the class-map command. A traffic class is used to classify traffic.
  2. Create a traffic policy by using the policy-map command. A traffic policy contains a traffic class and one or more QoS features that will be applied to the traffic class. The QoS features in the traffic policy determine how to treat the classified traffic.
  3. Attach the traffic policy to the interface by using the service-policy command.

Steps 1 and 3 do not involve legacy QoS hidden or removed commands, which means that they are not within the scope of this document. For more information about these two steps, see the " Applying QoS Features Using the MQC " module in the Quality of Service Solutions Configuration Guide.

Legacy QoS Command Deprecation: Hidden Commands

Cisco IOS XE Release 2.6

To streamline Cisco IOS XE QoS, certain commands have been hidden, which means that if you try to view a hidden command by entering a question mark (?) at the command line, the command does not appear. However, if you know the command syntax, you can enter it. These commands will be removed in a future release.

The functionality provided by these hidden commands is replaced by similar functionality from the modular QoS CLI (MQC), which is a set of a platform-independent commands for configuring QoS.

The following commands were modified: custom-queue-list, fair-queue (WFQ), frame-relay adaptive-shaping (becn keyword), frame-relay adaptive-shaping (foresight keyword), frame-relay bc, frame-relay be, frame-relay cir, frame-relay congestion threshold de, frame-relay congestion threshold ecn, frame-relay custom-queue-list, frame-relay fair-queue, frame-relay fecn-adapt, frame-relay ip rtp priority, frame-relay priority-group, frame-relay qos-autosense, ip rtp priority, max-reserved-bandwidth, show interfaces fair-queue, show interfaces random-detect, show queue, show queueing, show traffic-shape, show traffic-shape queue, show traffic-shape statistics.

Legacy QoS Command Deprecation: Removed Commands

Cisco IOS XE Release 3.2S

The legacy QoS commands were removed. This means that you must use the appropriate replacement MQC commands.

The following commands were removed: custom-queue-list, fair-queue (WFQ), frame-relay adaptive-shaping (becn keyword), frame-relay adaptive-shaping (foresight keyword), frame-relay bc, frame-relay be, frame-relay cir, frame-relay congestion threshold de, frame-relay congestion threshold ecn, frame-relay custom-queue-list, frame-relay fair-queue, frame-relay fecn-adapt, frame-relay ip rtp priority, frame-relay priority-group, frame-relay qos-autosense, ip rtp priority, max-reserved-bandwidth, show interfaces fair-queue, show interfaces random-detect, show queue, show queueing, show traffic-shape, show traffic-shape queue, show traffic-shape statistics.
