Cause

예상된 동작입니다. VMkernel의 NetQ 로드 밸런서가 vmnic 대기열을 기반으로 MAC 필터를 추가하려고 할 때마다 이벤트 nmlx5_en_L2TableIndexAdd가 ESXi 로그에 기록됩니다. 마찬가지로 대기열에서 필터가 제거되면 이벤트 nmlx5_en_L2TableIndexRemove가 ESXi 로그에 기록됩니다.
이러한 이벤트는 이러한 필터의 이동이 호스트에 있는 MAC 필터(VM 및 VMK 포함)의 수와 로드 밸런서에서 관리하는 특정 Rx 대기열의 로드에 따라 달라지는 경우에도 생성됩니다.

Resolution

이러한 이벤트는 L2 테이블의 트래픽 필터링 변경 사항에 대해 사용자를 업데이트합니다. 정보 이벤트이므로 기능에는 영향을 주지 않습니다.
