Configuring Cisco IOS IP SLAs Operations
on the type of IP SLAs operation, it responds with time-stamp information for the source to make the
calculation on performance metrics. An IP SLAs operation performs a network measurement from the
source device to a destination in the network using a specific protocol such as UDP.

Note
DLSw+ operation. Before configuring any IP SLAs application, you can use the show ip sla application
privileged EXEC command to verify that the operation type is supported on your software image.
IP SLAs Responder and IP SLAs Control Protocol
The IP SLAs responder is a component embedded in the destination Cisco device that allows the system
to anticipate and respond to IP SLAs request packets. The responder provides accurate measurements
without the need for dedicated probes. The responder uses the Cisco IOS IP SLAs Control Protocol to
provide a mechanism through which it can be notified on which port it should listen and respond. Only
a Cisco IOS device can be a source for a destination IP SLAs Responder.
