V.92 Reporting Using RADIUS Attribute v.92-info

Last Updated: January 15, 2012

The V.92 Reporting Using RADIUS Attribute v.92-info feature provides the ability to track V.92 call information, such as V.92 features that are supported, the Quick Connect feature set that was attempted, the duration for which the original call was put on hold, and how many times Modem On Hold was initiated. The vendor-specific attribute (VSA) v.92-info is included in accounting "start" and "stop" records when modems negotiate a V.92 connection.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.

Prerequisites for V.92 Reporting Using RADIUS Attribute v.92-info

Before the network access server (NAS) can send attribute v.92-info information in accounting "start" and "stop" records, you must perform the following tasks:

  • Configure your NAS for authentication, authorization, and accounting (AAA) and to accept incoming modem calls.
  • Enable AAA accounting by using the aaa accounting network default start-stop group radius command in global configuration mode.
  • Familiarize yourself with the V.92 Quick Connect and V.92 Modem on Hold features. See Related Documents.

Restrictions for V.92 Reporting Using RADIUS Attribute v.92-info

  • If V.92 is not negotiated on your server, V.92 information will not be included in the accounting record.
  • Because the attribute v.92-info information is sent as a Cisco VSA, if you configure your RADIUS server as nonstandard (using a non-Cisco server), the V.92 call information will not be sent by default. However, you can still get the V.92 call information by first configuring the radius-server vsa sendcommand with the accounting keyword (that is, radius-server vsa send accounting).

Information About V.92 Reporting Using RADIUS Attribute v.92-info

V.92 Standard Overview

The International Telecommunication Union Telecommunication Standardization Sector (ITU-T) V.92 standard encompasses a number of specifications, including Quick Connect (QC), which dramatically improves how quickly users can connect with their Internet service provider (ISP), and Modem on Hold (MoH), which enables users to suspend and reactivate their dial-up connection to either receive or initiate a telephone call. V.92 also includes pulse code modulation (PCM) upstream, which boosts the upstream data rates from the user to the ISP to reduce transfer times for large files and e-mail attachments sent by the user.

VSA v.92-info

The VSA v.92-info information in RADIUS accounting "start" and "stop" records can help you track V.92 feature set information. The VSA is enabled by default for all sessions that reside over a modem call that is connected using V.92 model modulation.

The VSA information is displayed in the "start" and "stop" records as follows:

v92-info=<V.92 features supported>/<QC Exchange>/<Total MOH time>/<MOH count>

The VSA v92-info has the following four subfields:

  • V.92 features supported--All features that are available for the V.92 modem user who is dialing in. These features include QC, MoH, and PCM Upstream.
  • QC Exchange--If QC was initiated, this subfield states what feature set (within QC) was attempted.
  • Total MOH time--If MoH was initiated, this subfield indicates the duration for which the original call was put on hold.
  • MOH count--If MOH was initiated, this field indicates how many times the MOH was initiated.

The following is an example of VSA v92-info information displayed in an accounting record:

v92-info=V.92 QC MOH/QC Requested/60/1

How to Monitor and Verify V.92 Call Information

Monitoring V.92 Call Information

To monitor the V.92 information in the accounting "start" and "stop" records, you can perform the following task using some or all of the debug commands that are listed:

SUMMARY STEPS

1.    enable

2.    debug aaa accounting

3.    debug aaa authentication

4.    debug aaa authorization

5.    debug isdn event

6.    debug modem csm [slot/port | group group-number]

7.    debug ppp {negotiation | authentication}

8.    debug radius


DETAILED STEPS
  Command or Action Purpose
Step 1
enable


Example:

Router> enable

 

Enables privileged EXEC mode.

  • Enter your password if prompted.
 
Step 2
debug aaa accounting


Example:

Router# debug aaa accounting

 

Displays information about accountable events as they occur.

 
Step 3
debug aaa authentication


Example:

Router# debug aaa authentication

 

Displays information about AAA authentication.

 
Step 4
debug aaa authorization


Example:

Router# debug aaa authorization

 

Displays information about AAA and TACACS+ authorization.

 
Step 5
debug isdn event

Example:

Router# debug isdn event

 

Displays ISDN events occurring on the user side (on the router) of the ISDN interface.

 
Step 6
debug modem csm [slot/port | group group-number]

Example:

Router# debug modem csm 1/0 group 1

 

Displays call switching module (CSM) modem call information.

 
Step 7
debug ppp {negotiation | authentication}

Example:

Router# debug ppp authentication

 

Displays information on traffic and exchanges in an internetwork that is implementing the PPP.

 
Step 8
debug radius


Example:

Router# debug radius

 

Displays information associated with RADIUS.

Verifying V.92 Call Information

To verify that the V.92 call was correctly established, use the following show commands:

SUMMARY STEPS

1.    show modem [slot/port | group number]

2.    show port modem log [reverse slot/port] [slot | slot/port]

3.    show users [all]


DETAILED STEPS
  Command or Action Purpose
Step 1
show modem [slot/port | group number]


Example:

Router# show modem 1/0 group 1

 

Displays a high-level performance report for all the modems or a single modem inside Cisco access servers.

 
Step 2
show port modem log [reverse slot/port] [slot | slot/port]


Example:

Router# show port modem log

 

Displays the events generated by the modem sessions.

 
Step 3
show users [all]


Example:

Router# show users

 

Displays information about the active lines on the router.

 

Examples

The following V.92 reporting outputs are from the show port modem log and show users commands: 

Router# show port modem log 1/05

Troubleshooting Tips

If you see that V.92 call information is not being reported by AAA, ensure that the call is a V.92 call by using the show modem command or by looking at the modem logs by using the show modem logcommand.

Feature Information

V.92 Reporting Using RADIUS Attribute v.92-info

12.3(1)

The V.92 Reporting Using RADIUS Attribute v.92-info feature provides the ability to track V.92 call information, such as V.92 features that are supported, the Quick Connect feature set that was attempted, the duration for which the original call was put on hold, and how many times Modem On Hold was initiated. The vendor-specific attribute (VSA) v.92-info is included in accounting "start" and "stop" records when modems negotiate a V.92 connection.

This feature was introduced in Cisco IOS Release 12.3(1).
