Description

The number of times SCTP Transport has been rejected due to remote IP addresses validation failure based on SCTP Multihoming mode. This is valid only for SCTP Transports.

Measurement Scope

NE, Server

Recovery

1. 
   
2. If all is well, this measurement should have a zero value. A non-zero value indicates that the Adjacent Node has attempted to connect to the Peer IP Address at least once and but the connection attempt was rejected because the IP addresses advertised by the Adjacent Node failed validation.
3. Otherwise:
   1. Transport status can be viewed at Main Menu, and then Transport Manager, and then Maintenance, and then Transport.
   2. Check the event history log at Main Menu, and then Alarms & Events, and then View History, looking for Events 19411 - SCTP Transport closed due to failure of multihoming validation or 19412 - SCTP Transport Transport Configuration Mismatch which provide more details as to the actual cause of the failure.
   3. Verify that the SCTP validation mode is as desired.
   4. Verify that the Adjacent Node that represents the far-end of the association is configured with the correct address at Main Menu, and then Transport Manager, and then Configuration, and then Adjacent Node.
   5. Verify that the remote port configured at Main Menu, and then Transport Manager, and then Configuration, and then Transport for the association correctly identifies the port that the Adjacent node is listening on for SCTOp connections.
   6. It is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729 for assistance if needed.
