Configuring Cisco IOS IP SLAs Operations
This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) on the Cisco
ME 3800X and 3600X 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.

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.
