Configuring Cisco IOS IP SLAs Operations
This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) on the Catalyst
3750-X or 3560-X 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 IP base or LAN base feature set support only IP SLAs responder functionality and
must be configured with another device that supports full IP SLAs functionality, for example, a
Catalyst 3750-X switch running the IP services feature set.
Note Unless otherwise noted, the term switch refers to a Catalyst 3750-X or 3560-X standalone switch and to
a Catalyst 3750-X switch stack.
Beginning with Cisco IOS 12.2(58)SE, 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. For information on configuring this
feature, see the Configuring Cisco IOS IP SLAs Video Operations document at:
