"Cisco IOS IP Service Level Agreements (SLAs) is a network performance
measurement and diagnostics tool that uses active monitoring, which
generates traffic in a reliable and predictable manner to measure

A summary of IP SLA capabilities is given below. More information is
available at www.cisco.com/go/ipsla.
