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
.

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:

•
Bandwidth Management Using RSVP Agents
Quality of Service (QoS) 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.

Cisco 7206 Router Configuration
This section shows a portion of the configuration file for a Cisco 7206 core router that was used in QoS
testing. It demonstrates how to configure auto qos voip trust on the WAN-to-LAN edge using Cisco
AutoQoS. For additional installation and configuration information, see the Cisco 7200 series router
documentation available at

Bandwidth Management Using RSVP Agents
The RSVP agent enables Cisco Unified Communications Manager to provide resource reservation for
voice and video media to ensure QoS and call admission control (CAC). 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
RSVP Configuration on Cisco Routers
