Application

Provisions the Application, Auth-Application and Acct-Application AVPs in messages sent by a node and identifies the Diameter application supported by the node. The Application selection determines which Authentication algorithms display for your selection.

Parameter Class: Basic: Custom Multiple Choice Values:

Tcl Parameter:

• When you select the WiMAX MIP4, the AAA Nodal is only used to simulate HA NAS. You can create another NAS to simulate FA NAS by configuring the application as EAP.

• To configure EAP Authentication and any auth-request-type as part of the same session:

You may select the Wm interface to allow EAP authentication, you can also configure any Auth-request-type as part of the same session (for example, you can configure the NASREQ/NASResponse Auth-request-type via  AVP Configuration).  

• Selecting S6b/STa Interfaces supports both STa and S6b interfaces simultaneously for the same UEs.

WiMAX H4 Command Code

WiMAX HA4 Command Code checkbox is only available when the Wimax Mip4 option is selected from the Application dropdown list. Select the checkbox and enter the Command Code of the message type not defined by IANA official codes.

Tcl Parameter: DiaCmdCodeWha4En

AAA Test

Use the drop-down list to select the types of transactions that are included in the test: authentication, accounting, or both. The types of transactions affect the way RADIUS sessions are connected and disconnected...

Options: Authentication With Accounting, Authentication Only, or Accounting Only

Default: Authentication With Accounting

Tcl Parameter: DiaClnAaaTestType

IP Mobility Mechanism

Options = GTP/PMIPv6 (S2b) - S2b is the reference point between ePDG (Evolved Packet Data Gateway) and PGW, which is based on GTP or PMIPv6 (Proxy Mobile IP version 6). Both GTp and PMIPv6 are network based IP mobility protocols.

Options = DSMIPv6 (S2c) - S2c is the reference point between the UE and PGW, which is based on DSMIPv6 (Dual-Stack Mobile IP version 6). DSMIPv6 is a host based IP mobility protocol.

Tcl Parameter: DiaClnIpMobMech

User Name and Password

When you set Application as S6b Interface, STa Interface, SWm or S6b/STa Interfaces, authentication is performed without password (the Password selection is not available).

See User Credentials

Tcl Parameter: DiaClnAaaTestType

NAS Identifier

The NAS-Identifier attribute in RADIUS requests sent to the SUT, formatted as the Fully Qualified Domain Name (FQDN) of the NAS. The name must be unique within the scope of the SUT. Either the NAS-IP-Address or the NAS-Identifier attribute is required by RADIUS. Use the checkboxes in the Authentication and Accounting panes to include the attribute in Access Request and Accounting Request messages respectively.

If more than one NAS is used in the test, a unique name must be provisioned for each NAS. The default value will produce unique names in the format spcoastn@nasdomain, where n begins at 1 and increments for each NAS. Alternatively, you can use the Auto-Increment feature to generate custom names.

Range: <host name>@<domain>

Default: @nasdomain

SUT Port

The TCP port that is used with Diameter on all SUTs.

Range: 0 - 65535

Default: 3868

Tcl Parameter: DiaClnSutPort

UE MAC Address

Enter valid starting MAC Address. It will be incremented for each user. Available when Application = Wa or Wa/Wm/Wg.

Default: a1:b2:c3:d4:e5:f6

Tcl Parameter: UeMacAddr

Authentication Type

Select the type of authentication performed by the SUT.

Options: CHAP, PAP, EAP, or DIGEST (DIGEST is only supported with RADIUS)

Default: CHAP

When you select CHAP, you can define the Challenge Length in the field provided.

Range: 1 — 128

Default: 16

Tcl Parameter: DiaClnChapChallengeLen

When you select EAP, you can configure the methods that will be supported and the credentials used for each method with the EAP Settings window.

Obtain IP Address by AAA

Enable to request that the AAA SUT allocate and return an IP address for an MN in the authentication response message. When address allocation is used, the address received is automatically included in the Framed-IP-Address attribute in any accounting requests sent to the SUT.

The IP address from this parameter is also transferred to the following messages including MIP RRQ, CCR if PDF Diameter, and Accounting-Request.

Tcl Parameter:

Reauthenticate Intervals

Enabling the Reauthenticate checkbox and specifying the interval  ensures that the current session is reauthenticated according to the specified interval.

To ensure re-authentication, a unique authenticator value is included in all subsequent Access-Request messages for the current session (Network Access Authentication between NAS and Home AAA), if known by the NAS.

For example, if you are running AAA Diameter test with EAP and you want to see the WiMAX AAA-Session-ID in the reauthentication messages, you would configure the reauthentication interval as described above and then go to the AVP Configuration window and select AAA-Session-ID from the WiMAX library, edit that AVP and check the "Re-Authentication Eap Request" box (if your Dameter test is not using EAP, check the "Re-Authentication AA Request").  This will add the desired AVP into the Diameter EAP Re-auth requests.

Tcl Parameter:

Wm Tunnel Establishment Delay (s)

A timer value to trigger tunnel establishment over Wm. Only available when Application = Wa/Wm/Wg.

Range : 1 to 65535

Default = 1

Tcl Parameter: DiaClnWmTunnelEstDelay

Authorization Start Delay

Enter the Authorization Start Delay in seconds. Enter value to simulate delay at the PGW to start S6b authorization procedure after a successful authentication procedure (for example, Gateway session establishment through Gxa, IP-CAN session establishment through Gx, etc.)

Not available for S6b Interface.

Default: 2 seconds.  

Tcl Parameter: DiaClnAuthorizationStartDelay

Number of APNs

Select the number of APNs to be defined for S6b, S6b/STA Interfaces.

Tcl Parameter: DiaClnNumApns

APN Assignments

Use the APN Assignments pane to define the APN values assigned to S6b, S6b/STA PDN contexts. You can define one APN for all contexts, a different APN for every context, or a set of APNs that are distributed among all contexts.

Tcl Parameter:

W-APN

Enter the WLAN APN Id that applies the charging/routing Policy. This is the W-APN to which the UE requests authorization.

This AVP is included in Authentication-Request-Type AVP, when set to AUTHORIZE_AUTHENTICATE.

Tcl Parameter: DiaClnWmWgApn

Charging ID

Enter the PDG Charging ID. The PDG charging identifier is generated by PDG and used to correlate PDG and WLAN Access Network charging data.

This AVP is included in Authentication-Request-Type AVP, when set to AUTHORIZATION_AUTHENTICATE.

Option: 0 -  4294967295

Default: 1.

Tcl Parameter: DiaClnWmWgChargeId

WAG Initiated Routing Policy Cancellation Timer

Select and enter the required length of time to wait before cancelling the WAG Initiated Routing Policy.

Optional Accounting Request Attributes

Select to provision the following RADIUS attributes in Accounting Request messages with values defined in or generated by the test case.

• Message Includes the User Name — The User-Name attribute is included and is provisioned with User Name.

• Message Includes the NAS IP Address — By default, the NAS-IP-Address attribute is included and is provisioned with the address of the NAS node associated with the MN.

  TIP: You can add the NAS-IP-Address attribute to the VSA configuration and provision the attribute with a static or incrementing address that is different from the NAS node's address. If you use a custom attribute, be sure to clear the checkbox to prevent the inclusion of a second attribute.

• Message Includes the NAS Identifier — The NAS-Identifier attribute is included and is provisioned with NAS Identifier.

• Message Includes the MN Home Address — Mobile Subscriber home address allocated by the HA is included to the Diameter accounting message.
