Configuring Cisco IOS IP SLAs Operations
This chapter describes how to use Cisco IOS IP Service Level Agreements (SLAs) and the IETF
Two-Way Active Measurement Protocol (TWAMP) on the Cisco Industrial Ethernet 2000U Series (IE
2000U) and Connected Grid Switches, hereafter referred to as 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.
For more information about IP SLAs, see the documents listed in the “Related Documents” section on
page 16-6.

Information About 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
