Configuring Cisco Ios Ip Slas Operations; Understanding Cisco Ios Ip Slas - Cisco Catalyst 2975 Software Configuration Manual

Configuring Cisco IOS IP SLAs Operations

This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) on the Catalyst 2975
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. Unless otherwise noted, the
term switch refers to a standalone switch and to a switch stack.
The switch supports only IP SLAs responder functionality and must be configured with another device
Note
that supports full IP SLAs functionality.

Understanding Cisco IOS IP SLAs

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 various Cisco IOS IP SLAs operations can be used
for troubleshooting, for problem analysis, and for designing network topologies.
Depending on the specific Cisco IOS IP SLAs operation, various network performance statistics are
monitored within the Cisco device and stored in both command-line interface (CLI) and Simple Network
Management Protocol (SNMP) MIBs. IP SLAs packets have configurable IP and application layer
