Configuring Cisco IOS IP SLAs Operations

This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs ) on th e switch. Cisco

IP SLAs is a part of Cisco IOS software that allows Cisco customers to analyze IP ser vic e 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 under st an d net work

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.

Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.

Cisco IOS IP SLAs sends data across the network to measure performance between multiple network

locations or across multiple network paths. It simulates network data and IP services and collects

network performance information in real time. Cisco IOS IP SLAs generates and analyzes traffic either

between Cisco IOS devices or from a Cisco IOS device to a remote IP device such as a network

application server. Measurements provided by the v arious Cisc o IOS IP SLAs operatio ns can be used for

troubleshooting, for problem analysis, and for designing network topolo gies.

Depending on the specific Cisco IOS IP SLAs operation, various network performance sta tistic s are

monitored within the Cisco device and stored in both command-line interface (CLI ) and Simple Netw ork

Management Protocol (SNMP) MIBs. IP SLAs packets have configurable IP and application layer
