Symptoms

以下日志模式记录在 ESXi VMkernel 中。
日志片段：

Cause

这是预期行为。每次 VMkernel 的 NetQ 负载平衡器尝试基于 vmnic 队列添加 MAC 筛选器时，都会在 ESXi 日志中记录事件nmlx5_en_L2TableIndexAdd。同样，从队列中删除筛选器时，事件nmlx5_en_L2TableIndexRemove将记录在 ESXi 日志中。
当这些筛选器的移动取决于主机上存在的 MAC 筛选器（包括 VM 和 VMK）的数量以及由负载均衡器管理的特定 Rx 队列上的负载时，也会生成这些事件。

Resolution

这些事件会向用户更新对 L2 表的流量过滤更改。它们没有功能影响，因为它们是信息事件。
