RxAsnUnsolDownAck

Measurement Group: Association Exception

Measurement Type: Simple

Description: The number of unsolicited M3UA ASP-DOWN-ACK messages received on the association. Unsolicited ASP-DOWN-ACK messages can be sent by the SG to indicate that the SG cannot process traffic on the association.

Collection Interval: 30 min

Peg Condition: This measurement is incremented by one each time an unsolicited ASP-DOWN-ACK is received on the association.

Measurement Scope: NE, Server

Recovery:

  1. This measurement should have a zero value. A non-zero value means that the far-end of the association has stopped processing M3UA signaling. You can view Association status from the GUI main menu under SS7/Sigtran>Maintenance>Associations.
  2. Check the event history from the GUI main menu under Alarms & Events>View History, looking for Event ID 19227. Event ID 19227 will show exactly when the unsolicited ASP-DOWN-ACK was received.
  3. Verify whether the far-end of the association is undergoing maintenance.
  4. Contact My Oracle Support (MOS) for assistance if needed.
