Message:
Low BB_Credit detected on an ISL.
Severity:
Informational.
Explanation:
OpenTrunking firmware detected an ISL with no transmission BB_Credit for a period of time that exceeded the
configured low BB_Credit threshold. This indicates downstream fabric congestion.
Action:
No action is required for an isolated event or if the reporting ISL approaches 100% throughput. If this event
persists, relieve the low BB_Credit condition by adding parallel ISLs, increasing the ISL link speed, or moving
device connections to a less-congested region of the fabric.
Event data:
Byte 0 = Port number reporting low BB_Credit.
