22103 - SCTP Connection Impaired

Alarm Group:

DIAM

Description:

One or more paths of the SCTP multi-homed connection is down.

Severity:

Minor

Instance:

<TransConnName>

HA Score:

Normal

Auto Clear Seconds:

0 (zero)

OID:

eagleXgDiameterSCTPConnectionImpairedAlarmNotify

Cause:

A host IP interface for one of the paths in the connection is down. One of following cases can cause this alarm:

• A host IP interface is down
• A host IP interface is unreachable from the peer
• A peer IP interface is down
• A peer IP interface is unreachable from the host
• Network path is down between one host IP and the other peer IP
• Network congestion or large latency in network (resulting loss or late arrival of packets)

Diagnostic Information:

1. Export the Diameter and IPFE configuration information from the active SOAM.
2. Retrieve the software release information.
3. Test each path in the connection to determine which one is causing the connection to be impaired.
4. Capture pcap (tcpdump) trace of packets on the local host (of the specific interface of the MP reporting the issue), or on remote peer or on IPFE (if it is TSA addressed) to see if data traffic or the heartbeat is running on the network

Recovery:

1. The alarm clears when the connection is operationally unavailable or all paths are operationally available.
   Potential causes are:

   • A host IP interface is down.
   • A host IP interface is unreachable from the peer.
   • A peer IP interface is down.
   • A peer IP interface is unreachable from the host.
   • Network path is down between one host IP and the other peer IP.
   • Network congestion or large latency in network (resulting loss or late arrival of packets).
2. Identify the most recent SCTP Connection Impaired event in the event log for the connection and use the event's recovery steps to resolve the issue.
3. If the problem persists, it is recommended to contact My Oracle Support.
