IP Service Level Agreements (IP SLA)
IP SLA (Internet Protocol Service Level Agreement) is an active monitoring technology used for
measuring network performance and data transmission quality. Active monitoring involves continuous
cyclic generation of traffic, collection of information on its movement through the network and recording
of statistical data.
Measurement of network parameters can be done using various types of IP SLA operations. Types
of operations vary by protocols of generated traffic, measurement methods and measured parameters. At
this time, the following IP SLA operations are supported:
ICMP Echo
UDP Jitter
In order to use IP SLA operations, you should:
Create operation of the desired type and configure it.
Execute the operation in a cycle and let it run for some time.
View statistics collected during the lifetime of the operation.
Stop the cyclic execution if necessary.
Global configuration mode commands
Command line request in global configuration mode appears as follows:

Remove an existing IP SLA operation.
Privileged EXEC mode commands
Command line request in privileged EXEC mode appears as follows:
console#

Action
set ip sla start
index
index: (1..20)
Execute the cyclic operation.
set ip sla stop
