Link state changed to DOWN - Help me

Mon Aug 27 10:40:54 PDT 2007

Hi

I have such "link state changed to DOWN" problem. Some times ago I have had
"Watchdog timeout", which takes to "Link state changed to DOWN". After
enabling device polling, this problem solved. But there are a few days I
receive "Link state changed to DOWN" again. 

1.	Is that related to "promiscuous mode enabled/disabled" messages?
2.	What's the cause of this?
3.	Has my problem any solution?

Thank you in advance

Narek
