2.8.5.4 UDR Configuration for SFAPP

Configuring UDR fot SFAPP involves adding vSTP MP(s) to UDR and then configuring UDR on the ComAgent server.
As a prerequisites for UDR configuration, it is assumed that the user is aware of UDR and ComAgent functionality. Also, UDR must be installed and the UDR topology must be configured.
Perform the following steps:
  1. Add details about the vSTP MP on the ComAgent Remote Servers screen as a client by navigating to Communication Agent, and then Configuration, and then Remote Servers and clicking Insert on an active OCUDR NOAMP.
  2. Select the OCUDR server group from the Available Local Server Groups that needs to communicate with vSTP MP.
  3. From the active OCUDR GUI, navigate to Communication Agent, and then Maintenance, and then Connection Status and verify connection are InService.
  4. From the active OCUDR GUI, navigate to Communication Agent, and then Maintenance, and then Routed Services Status and verify the STPDbSvc status is Normal.

  6. Add the UDR NO IP in the ComAgent Remote Server screen as a Server.
  7. Select the STP MP server group from the Local SG that needs to communicate with UDR.
  8. Also add the Standby and DR NOs to the Local SG.
  9. Navigate to Communication Agent, and then Configuration, and then Connection Groups, select STPSvcGroup and click Edit.
  10. Add all available UDR NO servers.

Note:

An UPDATE request from vSTP is assigned to an Active UDR only. However, a READ request from vSTP can be assigned to both Active or Standby UDR.

To check the status of the UDR, navigate to Communication AgentMaintenanceHA Services Status. Check value for the Active SRs field for the UDR. If the value is 1, the UDR is in active status. Therefore, an UPDATE request will be sent to this UDR.
