Cause

É um comportamento esperado. Sempre que o balanceador de carga NetQ do VMkernel tenta ADICIONAR um filtro MAC com base em uma fila vmnic, o nmlx5_en_L2TableIndexAdd de eventos é registrado no log do ESXi. Da mesma forma, quando um filtro é removido da fila, o nmlx5_en_L2TableIndexRemove de eventos é registrado no log do ESXi.
Esses eventos também são gerados quando a movimentação desses filtros depende do número de filtros MAC (incluindo VMs e VMKs) presentes no host e da carga em uma fila Rx específica, que é gerenciada pelo balanceador de carga.

Resolution

Esses eventos atualizam o usuário sobre as alterações de filtragem de tráfego na tabela L2. Eles não têm impacto funcional, pois são eventos informativos.
