Recovery

  1. Error code 2xx/3xx is generated by DSR routing layer for various routing errors that result in the failure of routing the Diameter request to the PCRF.
  2. Go to the PCA NOAM GUI to check the server status from Main Menu, and then Status & Manage, and then Server to verify if some DA-MPs have failed (if some servers on the same side fail, the traffic will be distributed amongst the remaining DA-MPs).
  3. Go to Main Menu, and then Status & Manage, and then KPIs to check the ingress traffic rates of the DA-MPs. Each DA-MP in the site should have about the same ingress rate in normal situation
  4. Go to Main Menu, and then Alarms & Events, and then View History to search for relevant congestion alarms. The Display Filter may be set as Timestamp or Server to include Policy DRA, DRL, or DCL alarms.
  5. Check the PCA SOAM GUI Main Menu, and then Measurements, and then Report to search for relevant measurements.
