Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Media Path Analysis
Media Path Analysis
For Cisco Prime Collaboration Release 11.1 and earlier
Analyze Media Paths Using VSAA
The Video SLA Assessment Agent (VSAA) is used in Cisco Prime Collaboration to provide network path characteristics (that is, latency, jitter, and packet loss) metrics before deploying or upgrading Cisco Video, TelePresence, or IP Video Surveillance (IPVS) systems and site extensions.
 Note | If you have deployed Cisco Prime Collaboration in MSP mode, Media Path Analysis is not supported in a NAT environment. |
Verify that the VSA Agent is up and running at the two endpoints, and synchronized to the NTP server. You can download the VSA Agent software from the Cisco Prime Collaboration software download site on Cisco.com. See Video SLA Assessment Agent 3.1 Installation Guide for the installation guidelines.

You must use CTS1000 profile to deploy CTS 500 and 1000 and CTS3000 profile to deploy CTS 3000. You can create, edit, and delete profiles.
VSA Agent Assessment Results
For the individual streams, you can view the topology (layer 2 and layer 3) for the selected direction between endpoints in the Troubleshooting tab.
You can view the detailed troubleshooting workflow status for the top level and the individual streams using the Log tab. . The VSA Agent Assessment result also provides details on the path through the Path Assessment tab. You can view the troubleshooting summary information for testable devices, nontestable device, devices with packet loss threshold violation, devices with jitter threshold violation, and devices with DSCP violation.
A set of tests are run for the devices determined during troubleshooting. To start the Path Assessment test, click Path Assessment Tests, after the proactive troubleshooting is complete for the conference.
The Test Result tab displays the following charts. For these charts, only the results of last twenty tests are displayed.
