Legacy QoS Command Deprecation

The functionality provided by these hidden commands has been replaced by similar functionality provided via the modular QoS CLI (MQC).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 must now provision QoS by defining traffic classes, creating traffic policies containing those classes, and attaching those policies to the desired interfaces. This document lists the hidden commands and their replacement MQC commands.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and 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.

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 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 Commands Being Hidden

The table below lists the commands that have been hidden or removed. The table also lists their replacement commands (or sequence of commands).

Legacy QoS Command Deprecation: Hidden Commands

15.0(1)S 15.1(3)T

To streamline Cisco IOS 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, priority-group, random-detect, random-detect dscp, random-detect(dscp-based keyword), random-detect exponential-weighting-constant, random-detect flow, random-detect flow average-depth-factor, random-detect flow count, random-detect(prec-based keyword), random-detect precedence, random-detect-group, show interfaces fair-queue, show interfaces random-detect, show queue, show queueing, show random-detect-group, show traffic-shape, show traffic-shape queue, show traffic-shape statistics.

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 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.
