Configuring RSVP Support for LLQLast Updated: July 24, 2012
This chapter describes the tasks for configuring the RSVP Support for Low Latency Queueing (LLQ) feature. For complete conceptual information, see the chapter "Signalling Overview" in this book. For a complete description of the RSVP Support for LLQ commands in this chapter, see the Cisco IOS Quality of Service Solutions Command Reference. To locate documentation of other commands that appear in this chapter, use the command reference master index or search online. To identify the hardware platform or software image information associated with a feature, use the Feature Navigator on Cisco.com to search for information about the feature or refer to the software release notes for a specific release. Finding Feature InformationYour 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 at the end of this module. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required. RSVP Support for LLQ Configuration Task ListTo configure RSVP support for LLQ, perform the tasks described in the following sections. The tasks in the first two sections are required; the tasks in the remaining sections are optional.
Configuring Flow ClassificationTo configure flow classification, use the following command in global configuration mode: Enabling RSVP and WFQTo enable RSVP and weighted fair queueing (WFQ), use the following commands beginning in global configuration mode: DETAILED STEPS
Configuring a Burst FactorTo configure a burst factor, use the following command in interface configuration mode: Configuring a ReservationTo configure a reservation, use the following command in global configuration mode: Verifying RSVP Support for LLQ Configuration
SUMMARY STEPS
DETAILED STEPS Monitoring and Maintaining RSVP Support for LLQTo monitor and maintain the RSVP Support for LLQ feature, use the following commands in EXEC mode, as needed:
Example RSVP Support for LLQ ConfigurationThis section provides a configuration example for the RSVP Support for LLQ feature. In the following example, PQ parameters, including flow rate and burst factor, are defined: Router(config)# ip rsvp pq-profile ? <1-1048576> Max Flow Rate (bytes/second) voice-like Voice-like flows <cr> Router(config)# ip rsvp pq-profile 11000 1500 ? <100-4000> Max Peak to Average Ratio (in %) ignore-peak-value Ignore the flow's p/r ratio <cr> Router(config)# ip rsvp pq-profile 11000 1500 ignore-peak-value Router(config)# end Router# sh run | include pq-profile ip rsvp pq-profile 11000 1500 ignore-peak-value In the following example, RSVP is enabled: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface loopback 40 Router(config-if)# ip rsvp bandwidth ? <1-10000000> Reservable Bandwidth(KBPS) <cr> Router(config-if)# ip rsvp bandwidth 300 ? <1-10000000> Largest Reservable Flow(KBPS) <cr> Router(config-if)# ip rsvp bandwidth 300 30 ? <cr> Router(config-if)# ip rsvp bandwidth 300 30 Router(config-if)# end In the following example, WFQ is enabled: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface e0/1 Router(config-if)# fair-queue Router(config-if)# fair-queue 64 In the following example, a burst factor is configured: Router(config)# interface e3/0 Router(config-if)# ip rsvp burst policing 200 In the following example, a path is defined: Router(config)# ip rsvp sender 145.20.20.202 145.10.10.201 udp 10 20 145.10.10.201 loopback 10 80 10 In the following example, a reservation is defined: Router(config)# ip rsvp reservation 145.20.20.202 145.10.10.201 udp 10 20 145.20.20.202 lo20 ff load 80 10 Cisco and the Cisco logo are trademarks or registered trademarks of Cisco and/or its affiliates in the U.S. and other countries.
