Understanding the Diameter Configuration Sequence

Use the Diameter > Configuration GUI pages to manage Diameter configuration.

Some components must be configured before others can be configured.

Diameter configuration on the SOAM must occur in the following order, because some are dependent on one another:

1. For DA-MPs, make any needed changes to configurable elements in the MP Profiles used for the DA-MPs in the system; and assign MP Profiles to the DA-MPs. See the MP Profiles information in Diameter Common User's Guide.
2. Configure Application Route Tables. See Diameter Application Route Tables.

   Configure only the Table Names. The Application Routing Rules must be configured after Application IDs and Command Codes are configured.

3. Configure Pending Answer Timers. See Diameter Pending Answer Timers.
4. Configure Peer Route Tables. See Diameter Peer Route Tables.

   Configure only the Table Names. The Peer Routing Rules must be configured after Route Lists are configured.

5. Configure Routing Option Sets. See Diameter Routing Option Sets.
6. Configure Application IDs. See Using Application IDs to Identify Diameter Applications.
7. Configure Command Codes. See Diameter Command Codes.
8. Configure MCC Ranges if either the Full Address Based Resolution (FABR) or Range Based Address Resolution (RBAR) application is activated. See the MCC range information in Diameter Common User's Guide.
9. Configure CEX Parameters. See Diameter CEX Parameters.
10. Configure CEX Configuration Sets. See Capacity Configuration Sets.
11. Configure Connection Configuration Sets. See Diameter Configuration Sets.

    Modify the Default Connection Configuration Set or create new Connection Configuration Sets to match the SCTP, Diameter, and TCP options that apply to your network.

12. Configure Local Nodes. See Diameter Local Nodes.
13. Configure Transaction Configuration Sets. See Transaction Configuration Sets.
14. Configure Peer Nodes. See Diameter Peer Nodes.

    Enable Topology Hiding Status if Topology Hiding is applicable to the Peer Node. See Diameter Topology Hiding.

    Note:

    Topology Hiding is available on the NOAM only.
15. Configure Capacity Configuration Sets for use with the Per-Connection Ingress MPS Control feature and Validating Diameter Connection Capacity. See Capacity Configuration Sets.
16. Configure Egress Message Throttling Configuration Sets. See Egress Message Throttling Configuration Sets.
17. Configure Message Priority Configuration Sets. See Message Priority Configuration Sets.
18. Configure Connections. IPFE Initiator DA-MP can be configured from this GUI page. See Connections.
19. Configure Route Groups. See Diameter Route Groups.
20. Configure Route Lists. See Diameter Route Lists.
21. If Alternate Implicit Routing is used, edit Peer Nodes and select a Route List for each Alternate Implicit Routing element. See Diameter Peer Nodes.
22. Configure Message Copy Configuration Sets. See Message Copy Configuration Sets.
23. Configure Peer Routing Rules in each configured Peer Route Table. See Diameter Peer Route Tables.
24. Configure Egress Throttle Groups. See Diameter Egress Throttle Groups.
25. Configure TTPs.
26. Configure Reroute On Answer, if it is used in the system. See Diameter Reroute On Answer.
27. Configure Application Routing Rules in each configured Application Route Table. See Diameter Application Route Tables.
28. If necessary, add Application Priority Options. See Diameter Application Priority Options.
29. If necessary, change the default System Options (see Diameter System Options):
    • Enable the Per Connection Egress Message Throttling feature if it is used.
    • Enable the Message Copy Feature if it is used.
    • Change any default values as needed.
30. If necessary, enter or change default DNS Options. See Diameter DNS Options.
31. Use the Diameter > Maintenance pages to enable configured components:
    • On the Diameter > Maintenance > Connections page, enable configured Connections.
    • On the Diameter > Maintenance > Egress Throttle Groups page, enable Egress Throttle Groups Rate Limiting, Egress Throttle Groups Pending Transaction Limiting, or both, if used.
    • On the Diameter > Maintenance > Applications page, enable configured Applications.
    • On the Diameter > Maintenance > Peer Discovery page, enable configured Peer Discovery.
    • On the Diameter > Maintenance > Signaling Firewall page, enable configured Signaling Firewall.
    • On the Diameter > Maintenance > Traffic Throttle Groups page, enable Traffic Throttle Groups.

The Diameter Topology Hiding components are configured in the following order on the NOAM:

1. Trusted Network Lists, which are used in the Protected Networks configuration
2. One or more Configuration Sets, for each Topology Hiding Type that is used:
   • Path Topology Hiding Configuration Sets
   • S6a/S6d Topology Hiding Configuration Sets
   • MME/SGSN Topology Hiding Configuration Sets
   • S9 PCRF Topology Hiding Configuration Sets
   • S9 AF/pCSCF Topology Hiding Configuration Sets
3. Protected Networks, which use the Trusted Network Lists and Configuration Sets in their configuration.
