Chapter 41 Configuring Cisco IOS IP SLAs Operations
Understanding Cisco IOS IP SLAs
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.

shows how IP SLAs begins when the source device sends
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.

Cisco IOS IP SLAs Operation
To implement IP SLAs network performance measurement, you need to perform these tasks:
1.
Enable the IP SLAs responder, if required.
2.
Configure the required IP SLAs operation type.
3.
Configure any options available for the specified operation type.
4.
Configure threshold conditions, if required.
5.
Schedule the operation to run, then let the operation run for a period of time to gather statistics.
6.
Display and interpret the results of the operation using the Cisco IOS CLI or a network
management system (NMS) system with SNMP.

Note
The switch does not support Voice over IP (VoIP) service level analysis or IP service level analysis using
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.
