Measurement ID

9141

Measurement Group

Association Exception

Measurement Type

Simple

Measurement Dimension

Arrayed (per association)

Description

The number of times the association timed out waiting for ASP-UP-ACK. ASP-UP-ACK is sent by the far-end in response to an ASP-UP message during the association start-up (when the association is in the Enabled administrative state).

Collection Interval

30 min

Peg Condition

This measurement is incremented by one each time an ASP-UP has been sent and the M3UA State Management ACK Timer expires, but no ASP-UP-ACK has been received for the association.

Measurement Scope

NE, Server

Recovery

1. This measurement should have a zero value. If the value is not zero, the association cannot be brought into the state necessary for M3UA ASPTM traffic because the far-end of the association is not responding by sending an ASP-UP-ACK prior to the timeout defined in the GUI under SS7/Sigtran, and then Configuration, and then Options, and then M3UA. The field that defines the timeout is the State Management ACK Timer.
2. You can view Association status from the GUI main menu under SS7/Sigtran, and then Maintenance, and then Associations.
3. Check the event history from the GUI main menu under Alarms & Events, and then View History, looking for Event ID 19226. Event ID 19226 will show when the timeout occurred.
4. Verify that the far-end of the association on the SG is not undergoing maintenance.
5. Verify that the State Management ACK Timer value is not set too short. This should not occur if the IP network is functioning correctly.
6. Verify that the IP network between the MP server and the SG is performing up to expectations.
7. It is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729 for assistance if needed.
