第一次發生,AM 3...(恕刪)
我用RB450G, RuterOS 5.5 測試, 已經用/system reset-configuration 重設,
LAN,WAN常常會有突然 linkup, link down,
Linux PC (Ubuntu 10.04)接在LAN,用dhclient eth0獲得ip之後,
renewal in 107232 sec,照理說應該可以用該IP 29小時,
可是常常是半小時沒上網, eth0 的IP 就不見了!
另外若是用WinXP連接RB450G 的LAN端,
則常常會突然顯示"區域連線 電纜已經拔除"這樣的訊號,但是實際上我沒拔網路電纜,
看起來好像是RB450G自己關閉LAN端的網路線,然後重啟動網路介面.

我倒是有一個類似狀況...(恕刪)
找到有用的資料:
在 mikroktik 論壇 47937 討論緒有其它人提到RB450G這個link goes up and down a number of times問題,
跟 1Gbit link requires auto-negotiation enabled at all times有關.
==========
從 Broadcom 網站找到的資料:
Why is there no option to force the speed and duplex to 1000Mb/s - Full Duplex?
Per the IEEE standard, the only IEEE compliant way to operate at 1000Mb/s-Full duplex is through auto-negotiation. If the network switch being used is IEEE compliant, the link speed will auto-negotiate to 1000Mb/s-Full duplex when autoneg is selected.
