Introduction

This document describes a sample configuration using an access server to accept incoming Analog and ISDN connections, and authenticate them using an authentication, authorization, and accounting (AAA) Remote Authentication Dial-in User Service (RADIUS) server. For more information on AAA and RADIUS, refer to the following documents:

Prerequisites

Requirements

This configuration assumes the RADIUS server is correctly set up. This configuration also works with most commercially available RADIUS servers. Refer to your RADIUS server documentation for further information on the proper server configuration.

Components Used

The information in this document is based on the software and hardware versions below.

  • Cisco AS5300 with a T1 PRI and 48 Digital modems. It is running Cisco IOS® Software Release 12.0(7)T.

  • CiscoSecure for Unix (CSU) server, Version 2.3(3).

The AAA specific configuration described here can be also used with any simple dial scenario. Ensure that the access server can accept incoming calls, then add the appropriate AAA commands, as shown in the configuration below.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Conventions

For more information on document conventions, see the Cisco Technical Tips Conventions.

Configure

In this section, you are presented with the information to configure the features described in this document.

Note: To find additional information on the commands used in this document, use the Command Lookup Tool (registered customers only) .

Network Diagram

This document uses the network setup shown in the diagram below.

Configurations

The CSU and CiscoSecure NT (CSNT) configuration, and network access server (NAS) configuration are provided below. Since this configuration depicts a simple dialin scenario, the CiscoSecure configuration for the ISDN and Async users are identical. The ISDN client configuration is not included as it is not relevant for this RADIUS configuration.

CSU
# ./ViewProfile -p 9900 -u async_client
 User Profile Information
 user = async_client{
 profile_id = 110
 profile_cycle = 2
 radius=Cisco {
 check_items= {
 2=cisco

 !--- Password(2) is "cisco"

 }
 reply_attributes= {
 6=2

 !--- Service-Type(6) is Framed (2)

 7=1

 !--- Frame




 d-Protocol(7) is PPP (1)

 }
    }
 }

 # ./ViewProfile -p 9900 -u isdn_user
 User Profile Information
 user = isdn_user{
 profile_id = 24
 profile_cycle = 4
 radius=Cisco {
 check_items= {
 2=cisco

 ! --- Password(2) is "cisco"

 }
 reply_attributes= {
 6=2

 ! --- Service-Type(6) is Framed (2)

 7=1
 
! --- Framed-Protocol(7) is PPP (1)

 }
    }
 }

Note: For this simple scenario, the configurations of the Async and ISDN users are identical.

CSNT RADIUS

To configure the CiscoSecure NT (CSNT) RADIUS:

  1. Create new users named isdn_user and async_client.

  2. Configure the appropriate password in the User Setup section

  3. In the section for Internet Engineering Task Force (IETF) RADIUS Attributes, select the following items from the pulldown menu:

    Service-type (attribute 6) = Framed and Framed-Protocol (attribute 7)=PPP

    Note: You must click the checkbox located next to the attributes Service-Type and Framed-Protocol.

    Note: For this simple scenario, the configurations of the Async and ISDN users are identical.

 aaa new-model

 !--- Initiates the AAA access control system. 
 !--- This command immediately locks down login and PPP authentication.

 aaa authentication login default group radius local

 !--- Exec login (for the list default) is authenticated using methods 
 !--- radius then local. The router uses RADIUS for authentication at the  
 !--- login(exec) prompt. If RADIUS returns an error, the user is authenticated 
 !--- using the local database.

 aaa authentication login NO_AUTHEN none

 !--- Exec login (for the list NO_AUTHEN) has authentication method none 
 !--- (no authentication). Interfaces to which this list is applied will not have 
 !--- authentication enabled. Refer to the console port (line con 0) configuration.

 aaa authentication ppp default if-needed group radius local

 !--- PPP authentication (for the list default) uses methods radius then local.
 !--- The if-needed keyword automatically permits ppp for users that have 
 !--- successfully authenticated using exec mode. If the EXEC facility has 
 !--- authenticated the user, RADIUS authentication for PPP is not performed.
 !----This is necessary for clients that use terminal window after dial.

 aaa authorization network default group radius local

 !--- Authorization of network services (PPP services) for the list default
 !--- uses methods radius then local. This is neccessary if you use RADIUS 
 !--- for the client IP address, Access List assignment and so on.

 enable secret 5 <deleted>
 !
 username admin password 7 <deleted>

 !--- This username allows for access to the router in situations where 
 !--- connectivity to the RADIUS server is lost. This is because the AAA 
 !--- configuration for exec login has the alternate method local.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Troubleshooting Commands

Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output.

Note: Before issuing debug commands, please see Important Information on Debug Commands.

  • debug isdn q931 - This shows call setup and tear down of the ISDN network connection (Layer 3) between the router and ISDN switch.

  • debug modem - This shows modem line activity on an access server.

  • debug ppp negotiation - To display information on the PPP traffic and exchanges while negotiating Link Control Protocol (LCP), authentication, and Network Control Protocol (NCP). A successful PPP negotiation first opens the LCP state, then authenticates, and finally negotiates NCP.

  • debug ppp authentication - To display PPP authentication protocol messages, including Challenge Handshake Authentication Protocol (CHAP) packet exchanges and Password Authentication Protocol (PAP) exchanges.

  • debug aaa authentication - To display information on AAA/RADIUS authentication.

  • debug aaa authorization - To display information on AAA/RADIUS authorization.

  • debug radius - To display detailed debugging information associated with the RADIUS. Use the Ouput Interpreter Tool (registered customers only) on the Cisco Technical Support Website to decode the debug radius messages. For an example, refer to the debug output shown below. Use the information from debug radius to determine what attributes are negotiated. Note: As of 12.2(11)T the output of debug radius is already decoded and hence does NOT require the use of Output Interpreter to decode the output. Refer to the document RADIUS Debug Enhancements for more information

  • show caller user - To show parameters for the particular user such as the TTY line used, asynchronous interface (shelf, slot or port), DS0 channel number, modem number, IP address assigned, PPP and PPP bundle parameters, and so on. If your version of Cisco IOS Software does not support this command, use the show user command.

The attribute value pairs (AVPs) from the debug radius command need to be decoded to better understand the transaction between the NAS and the RADIUS server.

Note: As of 12.2(11)T the output of debug radius is already decoded and hence does NOT require the use of Output Interpreter to decode the output. Refer to the document RADIUS Debug Enhancements for more information.

The Output Interpreter tool allows you to receive an analysis of the debug radius output.

The following output in italics is the result obtained from the Output Interpreter tool:

Access-Request 172.22.53.201:1645 id 13
Attribute Type 4:  NAS-IP-Address is 172.22.53.141
Attribute Type 5:  NAS-Port is 20006
Attribute Type 61: NAS-Port-Type is ISDN-Synchronous
Attribute Type 1:  User-Name is isdn
Attribute Type 30: Called-Station-ID(DNIS) is 8156
Attribute Type 3:  CHAP-Password is (encoded)
Attribute Type 6:  Service-Type is Framed
Attribute Type 7:  Framed-Protocol is PPP
Access-Accept 172.22.53.201:1645 id 13
Attribute Type 6:  Service-Type is Framed
Attribute Type 7:  Framed-Protocol is PPP

From the debug output decoded by the tool, verify that Attribute Type 6: Service-Type is Framed and Attribute Type 7: Framed-Protocol is PPP. If you observe that Attributes 6 or 7 are not as shown, correct the user profile on the RADIUS server (refer to the Configuration section). Also notice that debug radius shows an Access-Accept, which indicates that the RADIUS server successfully authenticated the user. If the output shows an Access-Reject, then the user was not authenticated and you should check the username and password configuration on the RADIUS server. Another attribute to verify is Attribute Type 4: NAS-IP-Address. Verify that the value displayed by the Output Interpreter Tool matches the NAS IP address configured on the RADIUS server.

Note: Due to Cisco IOS constraints and differences in debug output with different versions, some attributes may be truncated (for example, User-Name, Called-Station-ID(DNIS)).

The AVPs from the debug radius command need to be decoded to better understand the transaction between the NAS and the RADIUS server.

Note: As of 12.2(11)T the output of debug radius is already decoded and hence does NOT require the use of Output Interpreter to decode the output. Refer to the document RADIUS Debug Enhancements for more information

The Output Interpreter tool allows you to receive an analysis of the debug radius output.

The following output in italics is the result obtained from the Output Interpreter tool:

Attribute Type 6:  Service-Type is Framed
Attribute Type 7:  Framed-Protocol is PPP
         Access-Accept 172.22.53.201:1645 id 14
Attribute Type 6:  Service-Type is Framed
Attribute Type 7:  Framed-Protocol is PPP

From the debug output decoded by the tool, verify that Attribute Type 6: Service-Type is Framed and Attribute Type 7: Framed-Protocol is PPP. If you observe that Attributes 6 or 7 are not as shown, correct the user profile on the RADIUS server (refer to the Configuration section). Also notice that debug radius shows an Access-Accept, which indicates that the RADIUS server successfully authenticated the user. If the output shows an Access-Reject, then the user was not authenticated and you should check the username and password configuration on the RADIUS server. Another attribute to verify is Attribute Type 4: NAS-IP-Address. Verify that the value displayed by the Output Interpreter Tool matches the NAS IP address configured on the RADIUS server.

Note: Due to Cisco IOS constraints and differences in debug output with different versions, some attributes may be truncated (for example, User-Name, Called-Station-ID(DNIS)).
