Configuring SBR Carrier Server Identification

You can configure SBR Carrier server identification by configuring the local identity, the local addresses advertised by the server during capability exchange request authentication, and the self names or realm names used by remote network elements to refer the local network element.

Setting Up the Local Identity for SBR Carrier

The local identity of SBR Carrier is specified by the server Origin-Host and Origin-Realm.

Note: The local identity of SBR Carrier is pre-configured with the Origin-Host=your-host.your-realm.net and the Origin-Realm=your-realm.net. Reconfigure these settings for your network environment.

1. Select Diameter Configuration > Local Network Element > Identification. The Identification page (Figure 129) appears.

   Figure 129: Identification Page

   
2. Enter the Origin-Host name of the server in the Host Name (Origin-Host) field.

   SBR Carrier uses this name in Origin-Host AVPs.

3. Enter the name of the realm or network in which the server resides in the Realm Name (Origin-Realm) field.

   SBR Carrier uses this realm name in Origin-Realm AVPs.

4. Click Save to save the server identification configuration.

Configuring Local Addresses for the SBR Carrier Server

The local addresses specify IP addresses that the server uses for sending Diameter Capabilities Exchange messages (CER/CEA messages) between Diameter peers. The first Diameter message exchanged between two Diameter peers, after establishing the transport connection, is the Capabilities Exchange message. The Capabilities Exchange message carries a peer's identity and its capabilities (such as the protocol version number and the supported Diameter applications). A Diameter node only transmits commands to peers that have advertised support for the appropriate Diameter application.

1. Select Diameter Configuration > Local Network Element > Identification. The Identification page (Figure 129) appears.
2. Click Add in the Local Address area.

   The Add Local Address dialog box (Figure 130) appears.

3. Enter the IP address of the server in the IP Address field.
4. Optionally, select the Use IPv6 check box to use IPv6 addressing.

   Note: SBR Carrier does not support an embedded IPv4 address as an IPv6 address.

5. Click OK.

   The Local Address area displays an updated list of local address entries.

1. Select Diameter Configuration > Local Network Element > Identification. The Identification page (Figure 129) appears.
2. Select the local address entry you want to delete.
3. Click Delete in the Local Address area.

   A confirmation dialog box is displayed.

4. Click Yes to delete the address.

   The Local Address area displays an updated list of local address entries.

Configuring Local Realm for the SBR Carrier Server

Self names specify the realm names. The Network Access Identifier (NAI) in the request identifies the intended realm name for servers. In order to properly interpret requests received from intermediate servers, SBR Carrier must know which realms it is responsible for servicing locally.

When a request is received, the server examines the NAI to determine the realm to which the request should be routed. If the request does not contain an NAI, the Destination-Realm in the request is used. If the realm to which the request is to be routed is listed in the Self Names field, the realm is ignored and the request is treated as if it contained no realm. If no realm is present in either the NAI or the Destination-Realm, the request is considered to be local.

Note: If SBR Carrier receives a request for a realm not listed in the Self Names field, it will attempt to find a matching routing rule to determine how to route the request. For more information about request routing rules, see Administering Request Routing Rules .

1. Select Diameter Configuration > Local Network Element > Identification. The Identification page (Figure 129) appears.
2. Click Add in the Self Names area.

   The Add Self Name dialog box (Figure 131) appears.

3. Enter the realm name in the Name field.
4. Click OK.

   The Self Names area displays an updated list of realm entries.

1. Select Diameter Configuration > Local Network Element > Identification. The Identification page (Figure 129) appears.
2. Select the realm name entry that you want to delete.
3. Click Delete in the Self Names area.

   A confirmation dialog box is displayed.

4. Click Yes to delete the realm name.

   The Self Names area displays an updated list of realm entries.
