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:
Troubleshooting of network operation by providing consistent, reliable measurement that
immediately identifies problems and saves troubleshooting time.
Multiprotocol Label Switching (MPLS) performance monitoring and network verification (if the
switch supports MPLS)

Cisco IOS IP SLAs Operation
Enable the IP SLAs responder, if required.
1.
Configure the required IP SLAs operation type.
2.
Configure any options available for the specified operation type.
3.
Configure threshold conditions, if required.
4.
5.
Schedule the operation to run, then let the operation run for a period of time to gather statistics.
