Prerequisites for MQC-Based Frame Relay Traffic Shaping

Every permanent virtual circuit (PVC) to which FRTS using MQC is applied must have Frame Relay encapsulation enabled on the associated interface with the encapsulation frame-relay command.

---

Note For FRTS using MQC for the routers specified in the "Supported Platforms" section, distributed Cisco Express Forwarding is not required. For FRTS using MQC for routers in the Cisco 7500 and above product range, distributed Cisco Express Forwarding is required.

---

Restrictions for MQC-Based Frame Relay Traffic Shaping

You must create a default class for the service policy as specified with the class class-default command to configure FRTS using MQC on a Frame Relay PVC. The default class will have all the FRTS parameters applied to it. Refer to the "Creating a Policy Map and Entering CBWFQ Parameters for the Class Map" section for more information on creating a default class structure for a service policy.

If FRTS and fragmentation are applied to a PVC using MQC, the interface queue will change to dual first-in, first-out (FIFO) queueing. The two queues will consist of a high-priority queue to carry VoIP and certain control packets, and a low-priority queue to carry all other packets.

---

Note In configurations created by using traditional FRTS commands, the minimum acceptable outgoing committed information rate (minCIR) will be used as the total available bandwidth for a policy map that has class-based weighted fair queueing (CBWFQ) attached to the map class for the PVC.

If the MQC-Based Frame Relay Traffic Shaping feature is used to configure FRTS, the shaping rate that was configured in the parent policy map using MQC will be used as the total available bandwidth for the child policy map, if CBWFQ is configured. If both the shape average and shape adaptive commands are used for traffic shaping, the available bandwidth will be based on the parameters specified by the shape adaptive command

MQC Overview

MQC is used to configure FRTS. MQC is a framework that provides a clear separation between a classification policy and the specification of other parameters that act on the results of that applied classification policy.

Before this feature was introduced in Cisco IOS Release 12.2(13)T, FRTS for the Cisco routers specified in the "Supported Platforms" section could be configured only by using traditional FRTS commands (refer to the "How to Configure MQC-Based Frame Relay Traffic Shaping" section for more information). With the addition of the MQC-Based Frame Relay Traffic Shaping feature, FRTS can be configured on routers throughout the Cisco router product line by using MQC.

Broadly, MQC is configured and implemented as follows:

•Define a traffic class with the class-map command.

•Create a service policy by associating the traffic class with one or more QoS features (using the policy-map command).

•Attach the service policy to the interface with the service-policy command.

For more detailed information on MQC, refer to the document Modular Quality of Service Command-Line Interface. MQC commands used for FRTS are further explained in the "How to Configure MQC-Based Frame Relay Traffic Shaping" section of this document.

FRTS Overview

FRTS allows you to control the traffic going out through a PVC in order to match its flow to the speed of the remote target interface and to ensure that the traffic conforms to the parameters that have been set for it. Traffic that matches a particular profile can be shaped to meet downstream requirements, thereby eliminating the bottlenecks that occur in topologies that have data-rate mismatches.

The primary reasons you would use FRTS are the following:

•To allow high-priority packets to take precedence over other packets as they are encapsulated and forwarded over the Frame Relay network. FRTS is useful for applications such as VoIP and streaming video, which require a low latency to be effective.

•To control access to available bandwidth.

•To ensure that traffic conforms to the parameters established for it.

•To regulate the flow of traffic in order to avoid congestion that can occur when the sent traffic exceeds the access speed of its remote target interface.

•To eliminate bottlenecks in Frame Relay networks that have high-speed connections at the central site and low-speed connections at branch sites by configuring rate enforcement to limit the rate at which data is sent on the virtual circuit (VC) at the central site. Rate enforcement is a peak rate configured to limit outbound traffic.

Feature Design of MQC-Based Frame Relay Traffic Shaping

The MQC-Based Frame Relay Traffic Shaping feature allows the Cisco routers specified in the "Supported Platforms" section to have FRTS configured using MQC instead of traditional FRTS commands.

Before this feature was introduced in Cisco IOS Release 12.2(13)T, FRTS for the Cisco routers specified in the "Supported Platforms" section could be configured only by using traditional FRTS commands (for example, the frame-relay traffic-shaping command). For traditional FRTS, all traffic shaping and fragmentation values are entered under the map class. Traffic shaping is defined by entering the map-class frame-relay command, then entering the traffic shaping and, optionally, fragmentation values.

For routers in the Cisco 7500 and above product range, Distributed Traffic Shaping (DTS) is used for traffic shaping. With DTS, the traffic-shaping values are configured by entering the policy-map command, then entering the traffic-shaping values. However, fragmentation values are still entered under the map class—the map-class frame-relay command is still used before any fragmentation values are entered.

The traffic-shaping commands supported by the MQC-Based Frame Relay Traffic Shaping feature are listed in the "Supported MQC Frame Relay Traffic Shaping Commands" section.

CBWFQ can also be configured under the policy map by entering the policy-map command and then entering the traffic-shaping CBWFQ values.

---

Note Configuring traffic shaping using MQC and configuring traffic shaping using traditional FRTS commands are mutually exclusive. Traffic shaping cannot be configured on the same interface using both methods.

---

Supported MQC Frame Relay Traffic Shaping Commands

The following MQC traffic-shaping commands are supported by the MQC-Based Frame Relay Traffic Shaping feature:

•shape {average | peak}

•shape adaptive

•shape fecn-adapt

•shape max-buffers

The frame-relay ip rtp priority command is not supported.

---

Note Before this feature was introduced in Cisco IOS Release 12.2(13)T, FRTS for the Cisco routers specified in the "Supported Platforms" section could be configured only by using traditional FRTS commands (refer to the "How to Configure MQC-Based Frame Relay Traffic Shaping" section for more information).

---

Benefits of MQC-Based Frame Relay Traffic Shaping

MQC allows users to specify a traffic class independently of QoS parameters.

The MQC-Based Frame Relay Traffic Shaping feature allows users to apply FRTS parameters using MQC across the entire Cisco router product line.

This feature ensures that FRTS is defined in the same manner for routers across the Cisco router product line, rather than only for routers in the Cisco 7500 and above product range.

Before this feature was introduced in Cisco IOS Release 12.2(13)T, FRTS for the Cisco routers specified in the "Supported Platforms" section could be defined only by using traditional FRTS commands. Using different methods to define FRTS for different routers can introduce inconsistency and complexity when FRTS is being implemented on different router platforms.
