Configuring Cisco IOS IP SLA Operations
This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) on Catalyst 4500
series switch. Cisco IP SLAs is a part of Cisco IOS software that allows Cisco customers to analyze IP
service levels for IP applications and services by using active traffic monitoring—the generation of
traffic in a continuous, reliable, and predictable manner—for measuring network performance. With
Cisco IOS IP SLAs, service provider customers can measure and provide service level agreements, and
enterprise customers can verify service levels, verify outsourced service level agreements, and
understand network performance. Cisco IOS IP SLAs can perform network assessments, verify quality
of service (QoS), ease the deployment of new services, and assist with network troubleshooting.
Switches running the LAN base feature set support only the IP SLAs responder function and must be
configured with another device that supports full IP SLAs functionality, for example, a Catalyst 4500
series switch running the IP Base or Enterprise Services feature set.
The switch also supports the Built-in Traffic Simulator using Cisco IOS IP SLAs video operations to
generate synthetic traffic for a variety of video applications, such as Telepresence, IPTV and IP video
surveillance camera. You can use the simulator tool:
– for network assessment before deploying applications that have stringent network performance
requirements.
– along with the Cisco Mediatrace for post-deployment troubleshooting for any network related
performance issues.
The traffic simulator includes a sophisticated scheduler that allows the user to run several tests
simultaneously or periodically and over extended time periods ( Supported only on switches running the
Enterprise Services feature set). For information on configuring this feature, see the Configuring Cisco
IOS IP SLAs Video Operations document at:
