Chapter 42 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.
