Compliance, Performance, and TelePresence Traffic Assessment
During assessment, devices are evaluated to determine whether the network is ready for the deployment of a Cisco TelePresence solution. Assessment consists of three operations:
•
Running Compliance Analysis
• Running Performance Analysis (Creating a Performance Study)
• Running Telepresence Traffic Analysis
Running Compliance Analysis
Compliance analysis checks your devices against best practice rules for device software and hardware in the telepresence industry. You can view information about the best practice rules from the appendix of the Compliance Analysis Report. To check if the devices in your network comply with Cisco TelePresence deployments, do the following:
Step 1 Select Assessment > Compliance.
Step 2 Click Start Compliance. A confirmation window appears.
Step 3 Click OK to start the compliance analysis. Progress is shown in the status field:
•In Progress—Compliance analysis is in progress.
•Completed—Compliance analysis has completed successfully.
•Failed—Compliance analysis failed.
You can also click Refresh to check the status periodically.
Running Performance Analysis (Creating a Performance Study)
Performance analysis collects performance data for the devices in your network. The first time you run performance analysis, you select a subset of devices and set a schedule. Polling various devices in the network and gathering performance-related information over a period of time is called a study. Only one study can be processed at a time. After initial setup, the Status window always appears.
Step 1 Select Assessment > Performance > Performance Study. A list of devices that are in theTelePresence Readiness Assessment Manager inventory are displayed. If the list is long and you want to view only a subset of those devices, see Filtering the Device List.
Step 2 Select devices to include in the study.
Step 3 Click Next.
Step 4 Do one of the following:
•Select the One Time radio button to perform one study that will run continuously for a period of time.
In the From: field:
–Enter or select from the calendar icon the date you want the study to begin.
–From the lists, select the time you want the study to begin.
In the To: field:
–Enter or select from the calendar icon the date you want the study to end.
–From the lists, select the time you want the study to end.
•Select the Recurring radio button to perform a study that will run within a specified time for a number of days.
–In the From: field, enter or select from the calendar icon the date you want the study to begin.
–In the To: field, enter or select from the calendar icon the date you want the study to end.
–From the lists, select the times you want the study to begin and end.
Step 5 Click Finish. The Performance Data Collection Status page displays the details of the study that you just created. For more information, see Viewing Performance Study Details.
Filtering the Device List
If you have a very long device list, you might want to view only a specific set of devices. You can choose to filter (by IP address, DNS name, device classification (role) and polling interval) which devices to view by selecting an item from the available lists located at the top of the page. For example, to view all devices with IP addresses that begin with 172.20.12.*, do the following:
Step 1 From the first list, select IP Address.
Step 2 From the second list, select starts with.
Step 3 Enter 172.20.12 in the text field.
Step 4 Click Filter. A window appears with a filtered device list.
Step 5 Select devices to include in the study.
Step 6 Click Submit. The window closes, and the devices you previously selected are also selected in the Study Device Details Page.
Viewing Performance Study Details
If a performance study was set up, this is the first page you will see after selecting Assessment > Performance > Performance Study. If you did not set up a performance study, see Running Performance Analysis (Creating a Performance Study).
This page displays details of the study that was created. The following table lists available status and the function that can be performed.

Changing Device Poll Settings
Device poll settings can be changed according to their device categories (roles). Any changes to the poll settings are applied to all devices that belong to a particular device category. You can access this page from Assessment > Performance > Device Details.
Step 1 From each category, use the n list to select the new number of minutes for poll settings.
Step 2 Click OK.
Running Telepresence Traffic Analysis
TelePresence Readiness Assessment Manager enables you to simulate high-load telepresence traffic to run at different time intervals. It simulates telepresence traffic to predict the number of calls that the network can accommodate and gives insight to any voice and video impairment factors. It also provides audio and video QoS data that enables you to analyze network performance.
You can do a number of different scenarios, for example:
•Run a series of tests for an extended period of time to determine the stability of a network's performance. For example, you can run nightly tests for 15 days and vary certain parameters (video profile, video resolution, TOS settings, etc).
•Determine maximum bandwidth of a system by testing multiple systems simultaneously across a single network.
•Run multiple systems at different locations and simulat traffic at all possible point-to-point combinations.
To start simulating telepresence traffic in your network, you must have the Media TelePresence Analysis Agent installed on at least two systems in the network.
Note Before simulating traffic tests, close all open applications on the system. TelePresence Readiness Assessment Manager requires a dedicated system to accurately simulate telepresence traffic.
See the following topics:
• Installing the Media Traffic Analysis Agent on a System
• Managing Agents
• Managing Simulated TelePresence Traffic Tests
Installing the Media Traffic Analysis Agent on a System
Download the agent from the TelePresence Readiness Assessment Manager server to your system.
Note To simulate traffic, the Media TelePresence Analysis Agent must be installed on at least two systems (typically connected to the same switch that the proposed Cisco TelePresence Site (CTS) will be connected to).
Step 1 From your web browser, log in to TelePresence Readiness Assessment Manager server (see Starting TelePresence Readiness Assessment Manager, page 1-4).
Step 2 Select Assessment > Traffic Analysis > Download Agent.
Step 3 Click Save to copy the mtaaSetup.exe file to your system.
