Cause

Es el comportamiento esperado. Cada vez que el balanceador de carga NetQ de VMkernel intenta AGREGAR un filtro MAC basado en una línea de espera vmnic, el nmlx5_en_L2TableIndexAdd del evento se registra en el registro de ESXi. De manera similar, cuando se elimina un filtro de la cola, el nmlx5_en_L2TableIndexRemove del evento se registra en el registro de ESXi.
Estos eventos también se generan cuando el movimiento de estos filtros depende de la cantidad de filtros MAC (incluidas las VM y los VMK) presentes en el host y la carga en una cola de Rx específica, que administra el balanceador de carga.

Resolution

Estos eventos actualizan al usuario sobre los cambios de filtrado de tráfico en la tabla L2. No tienen ningún impacto funcional ya que son eventos informativos.
