某天有一個site的network出現問題, 需要reboot switch網絡才能正常運作, 但是reboot過後還是看到一些奇怪log在其中一個AP Port口, 相信問題未能真正解決, 最後還發現Mesh AP未能達到正常速度, 所以也都把Mesh的所有AP重啟一下, 從log上看到曾經出現Conflict IP address在reboot AP之後沒有再發生了, 相信問題發生在AP或end point, 但還是影響到整個網絡, 所以到Huawei開ticket, 然後建議的方法是[SW1]drop illegal-mac enable殺了destination MAC address=0000-0000-0000
