Symptoms

以下記錄模式會記錄在 ESXi VMkernel 中。
記錄片段：

Cause

這是預期的行為。每次 VMkernel 的 NetQ 負載平衡器嘗試根據 vmnic 佇列新增 MAC 篩選器時，事件nmlx5_en_L2TableIndexAdd都會記錄在 ESXi 記錄檔中。同樣地，從佇列移除篩選器時，事件nmlx5_en_L2TableIndexRemove會記錄在 ESXi 記錄中。
當這些篩選器的移動取決於主機上存在的 MAC 篩選器（包括 VM 和 VMK）的數量以及由負載均衡器管理的特定 Rx 佇列上的負載時，也會生成這些事件。

Resolution

這些事件會更新使用者對 L2 表的流量過濾更改。它們沒有功能影響，因為它們是資訊事件。
