Chapter 35 Configuring Cisco IOS IP SLAs Operations
Understanding Cisco IOS IP SLAs
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.
Figure 35-1 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.
For more information about IP SLAs operations, see the operation-specific chapters in the Cisco IOS IP
SLAs Configuration Guide at this URL:

Note The switch does not support Voice over IP (VoIP) service levels using the gatekeeper registration delay
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.
IP SLAs Responder and IP SLAs Control Protocol
The IP SLAs responder is a component embedded in the destination Cisco device that allows the system
to anticipate and respond to IP SLAs request packets. The responder provides accurate measurements
without the need for dedicated probes. The responder uses the Cisco IOS IP SLAs Control Protocol to
provide a mechanism through which it can be notified on which port it should listen and respond. Only
a Cisco IOS device can be a source for a destination IP SLAs Responder.
