Configuring Diameter and RADIUS Message Transport

From the point of view of other network elements, the IMS AAA Server acts as a Diameter and RADIUS network element. Therefore, the local transport configuration includes settings for both RADIUS and Diameter.

Configuring the Diameter Message Transport

If your network environment uses the Diameter protocol, you must configure the Diameter message transport on the server. If your environment does not use Diameter, you do not need to configure this feature.

To configure Diameter message transport:

  1. Select Local Network Element > Diameter Configuration.

The content frame displays the current configuration for Diameter Transports (Figure 23).


Figure 23: Main Diameter Transport Configuration Dialog
  1. Click New.

The New Diameter Transport dialog opens (Figure 24).


Figure 24: New Diameter Transport Dialog
  1. Enter a Name for the transport in the Name field.
  2. Enter the port number the server uses for Diameter messages in the Port field.
  3. Use the Protocol pulldown to select either SCTP or TCP as the transport protocol for Diameter messages.
  4. Enable the Use IPv6 Networking checkbox to use IPv6 formatting or leave it disabled to use IPv4 formatting.

    NOTE: The IMS AAA Server does not support embedding an IPv4 address in an IPv6 address.


  5. Click OK to save the new transport configuration.

Editing the Diameter Message Transport Configuration

To edit an existing Diameter transport configuration:

  1. Select the transport entry you wish to edit and click Edit. The Edit Diameter Transport dialog opens.

This dialog is the same as Figure 24.

  1. Edit the desired fields for the transport and click OK to save the edited configuration.

Deleting the Diameter Message Transport Configuration

To delete an existing Diameter transport configuration:

  1. Select the transport entry you wish to delete and click Delete.

The Confirm Delete dialog appears.

  1. Click Yes to delete the transport entry or No to cancel the operation.

Configuring RADIUS Message Transport

If your network environment uses the RADIUS protocol, you must configure the RADIUS message transport on the server. If your environment does not use RADIUS, you do not need to configure this feature.

To configure RADIUS message transport:

  1. Select Local Network Element > RADIUS Configuration.

The content frame displays the current configuration for each RADIUS message transport (Figure 25).


Figure 25: Main RADIUS Transport Configuration Dialog

As Figure 25 shows transport is configured separately for authentication, accounting, and dynamic authorization messages. The following procedure applies to all three message types.

  1. Select New in either the RADIUS authentication, accounting or dynamic authorization transport content frame. The New RADIUS Transport dialog opens (Figure 26).

Figure 26: New RADIUS Transport Dialog
  1. Enter a name for the transport in the Name field.
  2. Enter the port number the server uses for the RADIUS message type in the Port field.
  3. Enable the Use IPv6 Networking checkbox to use IPv6 formatting or leave it disabled to use IPv4 formatting.

    NOTE: The IMS AAA Server does not support an embedded IPv4 address as an IPv6 address.


  4. Click OK to save the new RADIUS transport configuration.
  5. Repeat steps 1 through 6 for each RADIUS message type.

Editing the RADIUS Message Transport Configuration

To edit an existing RADIUS transport configuration:

  1. Select the transport you wish to edit (either authentication, accounting or dynamic authorization transport) and click Edit.

The Edit RADIUS Transport dialog opens. This dialog is the same as Figure 26.

  1. Edit the desired fields and click OK to save the edited configuration.

Deleting the RADIUS Message Transport Configuration

To delete an existing RADIUS transport configuration:

  1. Select the transport entry you wish to delete (either authentication, accounting or dynamic authorization transport) and click Delete.

The Confirm Delete dialog opens.

  1. Click Yes to delete the transport entry, or No to cancel the operation.
