EvLnkActAckTO

Measurement Group: Link Exception

Measurement Type: Simple

Description: The number of times the link timed out waiting for ASP-ACTIVE-ACK. An ASP-ACTIVE-ACK is sent by the SG in response to an ASP-ACTIVE message on the link. The link is not available for M3UA data signaling until the ASP-ACTIVE-ACK is received.

Collection Interval: 30 min

Peg Condition: This measurement is incremented by one each time:
  • An ASP-ACTIVE has been sent for the link and the M3UA State Management ACK timer has expired, but no ASP-ACTIVE-ACK was received for the link.

Measurement Scope: NE, Server

Recovery:

  1. This measurement should have a zero value. You can view Link status from the GUI main menu under SS7/Sigtran>Maintenance>Links.
  2. Check the event history log from the GUI main menu under Alarms & Events>View History. Look for Event ID 19229, which shows when the ASP-ACTIVE-ACK timeout occurs.
  3. Verify that the far-end of the link on the SG is not undergoing maintenance.
  4. Verify that the State Management ACK Timer period is not set too short.
  5. Verify that the IP network between the MP server and the SG is performing up to expectations.
  6. Contact My Oracle Support (MOS) for assistance if needed.
