ether1-local link down

Hello.

I have two sextant installed and linked and they are working great doing the link and providing internet access to a customer. But one of the sextant has an issue, it loose the connectivity with the ether1-local so in the log window i can see every hour or so this message:


28/10/2011313:11:25 ether1-local link down
28/10/2011313:11:28 ether1-local link up (speed 1000M, full duplex)

I have done a cable-test in the terminal and it says all is ok.

Best regards.

I forgot to say the routeros version: 6.5
