Configuring RADIUS Tunnels

This section describes how to enable SBR Carrier to support tunnels. When you add a tunnel entry, you are not creating a tunnel; you are enabling SBR Carrier to support an existing tunnel’s authentication and accounting needs.

Adding a Tunnel

To add a tunnel entry using the Web GUI:

  1. Select RADIUS Configuration > Tunnels > Tunnels.

    The Tunnels List page (Figure 54) appears.

    Figure 54: Tunnels List Page

    Tunnels List Page
  2. Click Add.

    The Create Tunnel pane (Figure 55) appears with the Basic Configuration tab selected.

Pane—Basic Configuration
  3. Enter a name for the tunnel in the Name field.

    Tunnel names do not need to match the actual node name of a client tunnel server. The name you assign to a tunnel must not match the name assigned to a proxy target, realm, or tunnel in your SBR Carrier configuration.

  4. Enter a description for the tunnel in the Description field.

    Tunnel descriptions are used only for administrative purposes and do not affect tunnel connections. This field is typically used to identify the user or organization that uses the tunnel.

  5. If you want to limit the number of connections that can use the tunnel simultaneously, select the Maximum Open Tunnels check box and enter the maximum number of tunnels in the Maximum Open Tunnels field.
  6. Click the Attributes tab (Figure 56) to associate attributes and values with the tunnel.

    When a tunnel is used to make a connection, the attributes associated with the tunnel are filtered according to the make or model of the RADIUS client used to establish the connection.

  7. Click Add.

    The Add Tunnel List Attribute dialog box (Figure 57) appears.

List Attribute Dialog
  8. Select or enter a value for the selected attribute.

    The dialog changes according to the attribute you choose. Some attributes require that you enter a value, string, or IP address. Other attributes require that you choose from a fixed list of values.

    The Multivalued check box always appears dimmed, so you cannot select or clear this check box. If the Multivalued check box appears cleared, an attribute can have only one value. If the Multivalued check box appears selected, you can add multiple values for the attribute.

    The Orderable check box always appears dimmed, so you cannot select or clear this check box. If the Orderable check box appears selected, you can define the order of the multi-valued attributes. If the Orderable check box appears cleared, the attribute is neither a multi-valued attribute nor an orderable attribute.

  9. Click Add Attribute.
  10. Repeat steps 8 and 9 to add more attributes to the tunnel.
  11. When you are finished adding AVPs, click Close.

    The Attributes tab (Figure 56) displays an updated list of selected attributes.

    You can modify the attributes by using the Edit and Delete buttons. You can reorder the attributes by selecting each attribute and using the Up or Down arrow.

    Note: The Up arrow is disabled, if the selected attribute is not orderable or if the selected attribute is already the first value. The Down arrow is disabled, if the selected attribute is not orderable or if the selected attribute is already the last value.

  12. Optionally, click the Called Station IDs tab (Figure 58) to add one or more called station ID numbers for the tunnel.

    A called station ID number is a telephone number that was dialed to make a network connection. The called station ID number list identifies the Called-Station-Id attribute values that the server expects to find in tunnel connection requests.

  13. Click New.

    The Add Called Station ID dialog box (Figure 59) appears.

  14. Enter the number you want to use in the Called Station ID field.
  15. Click OK.
  16. Repeat steps 13 through 15 to add more called station ID numbers for the tunnel.

    The Called Station IDs tab (Figure 58) displays an updated list of called station ID numbers.

    You can modify the called station ID numbers by using the Edit and Delete buttons.

  17. Click Save to save the tunnel configuration.

    The Tunnels List page (Figure 54) displays an updated list of tunnel entries.

Editing a Tunnel

To edit a tunnel entry using the Web GUI:

  1. Select RADIUS Configuration > Tunnels > Tunnels.

    The Tunnels List page (Figure 54) appears.

  2. Select the tunnel entry that you want to edit.

    The Selected Tunnel pane (Figure 60) displays the settings configured for the tunnel.

  3. Edit the settings for the tunnel entry as appropriate.

    For more information about fields in the Selected Tunnel pane, see Adding a Tunnel.

    Note: You cannot edit the name of the tunnel.

  4. Click Save to save the changes.

    The Tunnels List page (Figure 54) displays an updated list of tunnel entries.

Deleting a Tunnel

To delete a tunnel entry from the SBR Carrier database:

  1. Select RADIUS Configuration > Tunnels > Tunnels.

    The Tunnels List page (Figure 54) appears.

  2. Select the tunnel entry that you want to delete.
  3. Click Delete.

    A confirmation dialog box is displayed.

  4. Click Yes to confirm the delete request.

    The Tunnels List page (Figure 54) displays an updated list of tunnel entries.
