Quality of Service and Bandwidth Management Configuration This topic provides a reference configuration for Quality or Service (QoS) and bandwidth management using RSVP within a Cisco Unified Communications deployment. The information is based primarily on testing performed during Cisco Unified Communications Release 6.1(1) system testing. This topic does not contain detailed step-by-step procedures; instead, for or detailed information about installing, configuring, and administering these functions, refer to the related Cisco documentation listed in Table 1. Related Documentation For related information about QoS and RSVP, see the documents listed in Table 1. Table 1 Cisco QoS and RSVP Documentation Document General Cisco QoS documentation Configuring RSVP Chapter in the Network Protocols Configuration Guide, Part 1 URL http://www.cisco.com/en/us/tech/tk543/tk759/tsd_ technology_support_protocol_home.html http://www.cisco.com/en/us/docs/ios/11_3/np1/co nfiguration/guide/1crsvp.html Reference Configuration The system-wide testing of IP telephony functionality for Cisco Unified Communications Release 6.1(1) included Cisco QoS and RSVP. For general information about the tested functionality in Cisco Unified Communications Release 6.1(1), see the System Release Notes for IP Telephony: Cisco Unified Communications System, Release 6.1(1). Network Topologies During Cisco Unified Communications Release 6.1(1) testing, this component was installed and tested in the following site models: SJC-RFD 1

Configuration Details This topic includes the following sections: Quality of Service (QoS) Configuration Bandwidth Management Using RSVP Agents Quality of Service (QoS) Configuration Cisco 3845 Router Configuration This section provides sample configuration files that show how Quality of Service (QoS) settings were configured on selected WAN routers during Cisco Unified Communications Release 6.1(1) testing for IP telephony. For the testing, QoS was configured on the following Cisco devices that passed VoIP traffic to and from SCCP, analog, and T1-PRI endpoints: Cisco 7206 router (central site) Cisco 2811 multiservice routers (remote site) Cisco 2821 multiservice routers (remote site) Cisco 2851 multiservice routers (remote site) Cisco 3825 multiservice routers (remote site) Cisco 3845 multiservice routers (remote site) These devices were configured for QoS based on the recommendations in the Enterprise QoS Solution Reference Network Design Guide http://www.cisco.com/univercd/cc/td/doc/solution/esm/qossrnd.pdf. This document provides design considerations and guidelines for implementing Cisco QoS within an enterprise environment on specific Cisco router types. Most devices tested during Cisco Unified Communications Release 6.1(1) were configured with Cisco AutoQoS. For additional information about AutoQos, see the Quality of Service Commands chapter in the Cisco IOS Quality of Service Solutions Command Reference at http://www.cisco.com/en/us/products/ps6441/products_configuration_guide_book09186a008065c7a1. html. For general information on QoS on Cisco devices, see http://www.cisco.com/en/us/tech/tk543/tk759/tsd_technology_support_protocol_home.html. This section includes portions of the configuration files for the following devices: Cisco 3845 Router Configuration Cisco 7206 Router Configuration This section shows a portion of the serial interface configuration for the Cisco 3845 router that was used in QoS testing.

The RSVP Agent registers with Cisco Unified Communications Manager as either a media termination point or a transcoder device. Each endpoint involved in a call normally requires an RSVP Agent. The agent pair (one agent for endpoint A, another agent for endpoint B) signals RSVP on behalf of the endpoints that Cisco Unified Communications Manager controls. Note RSVP does not support intercluster RSVP Agents.That is, RSVP does not support reservations between two RSVP Agents that are located in different Unified Communications Manager clusters. When a call takes place from a location that has RSVP Agent to another location that does not have RSVP Agent, Cisco Unified Communications Manager will manage the quality of service (QoS) of the call by using both location-based CAC and RSVP. The first part of the call, from the location that has RSVP Agent to the hub/central site that has RSVP, uses the RSVP mechanism. The second part of the call, from the hub/central site to the location that does not have RSVP, gets managed through location-based CAC. If either mechanism fails to allocate bandwidth, the call fails. 19
