Configuring Cisco IOS IP SLAs Operations
Using Cisco IOS IP SLAs to Measure Network Performance
You can use IP SLAs to monitor the performance between any area in the network—core, distribution,
and edge—without deploying a physical probe. It uses generated traffic to measure network performance
between two networking devices.
a generated packet to the destination device. After the destination device receives the packet, depending
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.

To implement IP SLAs network performance measurement, you need to perform these tasks:

operations measurements. 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.
