Cause

Si tratta di un comportamento previsto. Ogni volta che il sistema di bilanciamento del carico NetQ di VMkernel tenta di AGGIUNGERE un filtro MAC in base a una coda vmnic, l'evento nmlx5_en_L2TableIndexAdd viene registrato nel registro ESXi. Analogamente, quando un filtro viene rimosso dalla coda, il nmlx5_en_L2TableIndexRemove eventi viene registrato nel registro ESXi.
Questi eventi vengono generati anche quando lo spostamento di questi filtri dipende dal numero di filtri MAC (inclusi VM e VMK) presenti sull host e dal carico su una coda Rx specifica, gestita dal Load Balancer.

Resolution

Questi eventi aggiornano l'utente sulle modifiche del filtro del traffico alla tabella L2. Non hanno alcun impatto funzionale in quanto sono eventi informativi.
