Perform a Wireless Controller Voice Audit

Prime Infrastructure provides a voice auditing mechanism to check controller configuration and to ensure that any deviation from the deployment guidelines is highlighted as an Audit Violation. You can run a voice audit on a maximum of 50 controllers in a single operation.

To run the voice audit:

Procedure

Step 1

Choose Monitor > Tools > Wireless Voice Audit.

Step 2

Click the Controllers tab, and complete the fields as described in the Voice Audit Field Descriptions section in the following link http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-infrastructure/products-user-guide-list.html.

Step 3

Click the Rules tab.

Step 4

In the VoWLAN SSID text box, type the applicable VoWLAN SSID.

Note

 
The red circle indicates an invalid rule (due to insufficient data). The green circle indicates a valid rule.

Step 5

Do either of the following:

  • To save the configuration without running a report, click Save.

  • To save the configuration and run a report, click Save and Run.

Step 6

Click the Report tab to view the report results.

Check AP Performance Using the Voice Diagnostic Tool

The Voice Diagnostic tool is an interactive tool that diagnoses voice calls in real time. This tool reports call control errors, clients' roaming history, and the total number of active calls accepted and rejected by an associated AP.

The Voice Diagnostic test is provisioned for multiple controllers; that is, if the AP is associated with more than one controller during roaming, the Voice Diagnostic tool tests all associated controllers. Prime Infrastructure supports testing on controllers whose APs are placed on up to three floors. For example, a Prime Infrastructure map might have floors 1 to 4, with all APs associated to controllers (WLC1, WLC2, WLC3, and WLC4) and placed on the Prime Infrastructure map. If a client on any AP is associated with WLC1 on the first floor and a Voice Diagnostic test is started for that client, a test is also provisioned on WLC2 and WLC3.

The Voice Diagnostic page lists prior test runs, if any. For information about the fields on this page, see the Voice Diagnostic Field Descriptions section in the (http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-infrastructure/products-user-guide-list.html).

From the Select a command drop-down list, you can start a new test, check the results of an existing test, or delete a test.


Note
To support roaming, the tool figures out controllers in the same building as of client's associated AP building and adds to all controller's watchlist. The tool looks for controllers in +/-5 floors from client's current association A’s location to configure on controllers. Configuration on controller's watchlist is done for 10 minutes. After 10 minutes controller will remove the entry from the watchlist.

To run a Voice Diagnostic test:

Procedure

Step 1

Choose Monitor > Tools > Wireless Voice Audit.

Step 2

From the Select a command drop-down list, choose the New test and click Go.

Note

 
You can configure a maximum of two clients for voice call diagnosis. Both clients can be on the same call or can be on a different call.

Step 3

Enter a test name and the length of time to monitor the voice call.

Step 4

Enter the MAC address of the device for which you want to run the voice diagnostic test.

Step 5

Select a device type; if you select a custom phone, enter an RSSI range.

Step 6

Click Start Test.

Wireless Configuration Audit

Choose Monitor > Tools > Wireless Configuration Audit to launch the Configuration Audit Summary page.

This page provides a summary of the following:

  • Total Enforced Config Groups—Templates that are configured for Background Audit and are enforcement enabled.
  • Total Mismatched Controllers—Configuration differences found between Prime Infrastructure and the controller during the last audit.
  • Total Config Audit Alarms—Alarms generated when audit discrepancies are enforced on configuration groups. If enforcement fails, a critical alarm is generated on the configuration group. If enforcement succeeds, a minor alarm is generated on the configuration group. Alarms contain links to the audit report, where you can view a list of discrepancies for each controller.
  • Most recent 5 config audit alarms—Includes object name, event type, date, and time of the audit alarm.

Click View All to view the applicable Alarm page that includes all configuration audit alarms.

Determine Which Autonomous APs Can Be Migrated to Lightweight APs

Choose Monitor > Tools > Autonomous AP Migration Analysis to launch the Migration Analysis Summary page. Autonomous access points are eligible for migration only if all criteria have a pass status. A red X designates ineligibility, and a green check mark designates eligibility. These columns represent the following:

  • Privilege 15 Criteria—The Telnet credential provided as part of the autonomous access point discovery must be privilege 15.
  • Software Version—Conversion is supported only from Cisco IOS 12.3(7)JA releases excluding Cisco IOS 12.3(11)JA, Cisco IOS 12.3(11)JA1, Cisco IOS 12.3(11)JA2, and Cisco IOS 12.3(11)JA3.
  • Role Criteria—A wired connection between the access point and controller is required to send the association request; therefore, the following autonomous access point roles are required:
    • root
    • root access point
    • root fallback repeater
    • root fallback shutdown
    • root access point only
  • Radio Criteria—In dual-radio access points, the conversion can happen even if only one radio is of the supported type.

Ensure AP Location Accuracy with the Location Accuracy Tool

You can analyze the location accuracy of non-rogue and rogue clients, interferers, and asset tags by using the Location Accuracy tool.

By verifying for location accuracy, you are ensuring that the existing access point deployment can estimate the true location of an element within 10 meters at least 90% of the time.

The Location Accuracy tool enables you to run either of the following tests:

  • Scheduled Accuracy Testing—Employed when clients, tags, and interferers are already deployed and associated to the wireless LAN infrastructure. Scheduled tests can be configured and saved when clients, tags, and interferers are already prepositioned so that the test can be run on a regularly scheduled basis.
  • On-Demand Accuracy Testing—Employed when elements are associated but not pre-positioned. On-demand testing allows you to test the location accuracy of clients, tags, and interferers at a number of different locations. It is generally used to test the location accuracy for a small number of clients, tags, and interferers.

Both are configured and executed through a single page.

Set Up the AP Location Accuracy Tool

You must enable the Advanced Debug option in Prime Infrastructure to use the Scheduled and On-demand location accuracy tool testing features. The Location Accuracy tool does not appear as an option on the Monitor > Tools menu when the Advanced Debug option is not enabled.

To enable the advanced debug option in Prime Infrastructure:
