Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide

Monitoring and Maintaining Multilink Frame Relay

---

The Cisco Frame Relay implementation currently supports routing on IP, DECnet, AppleTalk, XNS, Novell IPX, CLNS, Banyan VINES, and transparent bridging. This guide describes how to monitor and maintain the Multilink Frame Relay feature for the Cisco ASR 1000 Series Routers.

Feature Overview

The Multilink Frame Relay feature is based on the Frame Relay Forum’s Multilink Frame Relay UNI Implementation Agreement (FRF.16). This feature provides a cost-effective way to increase bandwidth for certain applications by enabling multiple serial links to be aggregated into a single bundle of bandwidth. Multilink Frame Relay is supported on User-to-Network Interface (UNI) networks.

Configuring Multilink Frame Relay

The mulitlink frame relay configuration processes are described in the Frame Relay - Multilink (MLFR-FRF.16) feature guide. For more information, see the Frame Relay - Multilink (MLFR-FRF.16) feature guide at: http://www.cisco.com/en/US/docs/ios/ios_xe/wan/configuration/guide/wan_ml_fr_frf161_xe.html

Monitoring and Maintaining Frame Relay and Multilink Frame Relay

You can use different show and debug commands to monitor and maintain frame relay and multilink frame relay configurations.

You can use the following show commands to display the multilink frame relay configurations:

• show platform software frame-relay —Displays the statistics about frame relay permanent virtual circuits (PVCs).
• show platform software mfr —Displays statistics about multilink frame relay information.

You can use the following debug commands to debug the multilink frame relay configurations:

• debug platform hardware qfp active interface frame-relay multilink —Debugs the multilink frame relay interfaces in the Cisco QuantumFlow Processor (QFP).
• platform trace runtime process forwarding-manager module —Enables Forwarding Manager Route Processor and Embedded Service Processor trace messages for the forwarding manager process.

For additional information on the commands and the options available for each command, see the Cisco IOS Configuration Fundamentals Command Reference document, located at:
