Cause

Det är ett förväntat beteende. Varje gång VMkernels NetQ-lastbalanserare försöker lägga till ett MAC-filter baserat på en vmnic-kö loggas händelsen nmlx5_en_L2TableIndexAdd i ESXi-loggen. När ett filter tas bort från kön loggas händelsen nmlx5_en_L2TableIndexRemove i ESXi-loggen.
Dessa händelser genereras också när förflyttningen av dessa filter är beroende av antalet MAC-filter (inklusive virtuella datorer och VMK:er) som finns på värden och belastningen på en specifik Rx-kö, som hanteras av lastbalanseraren.

Resolution

Dessa händelser uppdaterar användaren om trafikfiltreringsändringar i L2-tabellen. De har ingen funktionell inverkan eftersom de är informationshändelser.
