Configuring Cisco IOS IP SLAs Operations
This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) on the 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.

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
options such as source and destination IP address, User Datagram Protocol (UDP)/TCP port numbers, a
type of service (ToS) byte (including Differentiated Services Code Point [DSCP] and IP Prefix bits),
Virtual Private Network (VPN) routing/forwarding instance (VRF), and URL web address.
