S9 AF/pCSCF Topology Hiding Configuration Sets provide information that is used to perform S9 AF/pCSCF Topology Hiding for a Protected Network's PCRFs, as well as the number of PCRFs in the network, when it exchanges messages with Untrusted Networks. A PCRF's identity is embedded in the Origin-Host and Session-ID AVPs sent in Request messages and the Origin-Host AVP sent in Answer messages.
The fields are described in S9 AF/pCSCF Topology Hiding Configuration Set elements.
Each S9 AF/pCSCF Topology Hiding Configuration Set contains the following information:
- S9 AF/pCSCF Topology Hiding Configuration Set Name - Unique name for this Configuration Set.
- Pseudo Hostname Generation - Attributes to control the format and generation of Pseudo Hostnames corresponding to an Actual Hostname.
- Count - The maximum number of Pseudo Hostnames associated with an Actual Hostname.
- Randomize Count - Allows random number of Pseudo Hostnames between 1 and Count to be associated with an Actual Hostname.
- Auto Generate - Allows Pseudo Hostnames to be automatically generated corresponding to an Actual Hostname.
- Prefix - Prefix for the auto-generated Pseudo Hostname.
- Suffix - Suffix for the auto-generated Pseudo Hostname.
- Length - Length of the random number used in the auto-generated Pseudo Hostname.
- Hostnames - List of Actual Hostnames and their Pseudo Hostnames in this S9 PCRF Topology Hiding Configuration Set.
- S9 AF/pCSCF Actual Hostname Not Found Action - Action to be performed when the Orig-Host in the Diameter message is not configured as Actual Hostname in this S9 AF/pCSCF Topology Hiding Configuration Set.
- S9 AF/pCSCF Actual Hostname Not Found Answer Result-Code Value - Value to be placed in the Result-Code AVP of the Answer message.
- S9 AF/pCSCF Actual Hostname Not Found Vendor Id - Vendor Id will be placed in Vendor Id AVP.
- S9 AF/pCSCF Actual Hostname Not Found Answer Error Message - String to be placed in the Error-Message AVP of the Answer message.
On the
Diameter > Configuration > Topology Hiding > S9 AF/pCSCF Topology Hiding Configuration Sets page, you can perform the following actions:
- Filter the list of S9 AF/pCSCF Topology Hiding Configuration Sets to display only the desired S9 AF/pCSCF Topology Hiding Configuration Sets.
- Sort the list by column contents in ascending or descending order (except Hostname Suffixes), by clicking the column heading. The default order is by S9 AF/pCSCF Topology Hiding Configuration Set Name in ascending ASCII order.
- Click the Insert button.
The Diameter > Configuration > Topology Hiding > S9 AF/pCSCF Topology Hiding Configuration Sets [Insert] page appears. You can add a new S9 AF/pCSCF Topology Hiding Configuration Set and its elements. See Adding an S9 AF/pCSCF Topology Hiding Configuration Set.
If the maximum number of S9 AF/pCSCF Topology Hiding Configuration Sets (500) already exists in the system, the Diameter > Configuration > Topology Hiding > S9 AF/pCSCF Topology Hiding Configuration Sets [Insert] page will not open, and an error message is displayed.
- Select a S9 AF/pCSCF Topology Hiding Configuration Set Name in the list, and click the Edit button.
The Diameter > Configuration > Topology Hiding > S9 AF/pCSCF Topology Hiding Configuration Sets [Edit] page opens. You can edit the selected S9 AF/pCSCF Configuration Set. See Editing an S9 AF/pCSCF Topology Hiding Configuration Set.
- Select a S9 AF/pCSCF Topology Hiding Configuration Set Name in the list, and click the Delete button to remove the selected S9 AF/pCSCF Topology Hiding Configuration Set. See Deleting an S9 AF/pCSCF Topology Hiding Configuration Set.
If the selected S9 AF/pCSCF Topology Hiding Configuration Set is used in a Protected Network, the Configuration Set will not be deleted.
