Table 50: Event Code 142
Message: Low BB_Credit detected on an ISL.
Severity: Informational.
Explanation Open Trunking 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.
