I have a Sun V100 system running Solaris 9 plus a cluster patch from late May
2005. The dmfe interface that is constantly going up and down.
The system is attached to a Cisco 2950. Both ends are auto-negotiating 100Mb
and full duplex. I do not see any network errors either on the Cisco side or
the Sun side.
I am getting this in the /var/adm/messages file:

I found these link in an effort to resolve my issue from a yahoo search:

I also poked around sunsolve and found patch 116561-06 which addressed these
issues:
4643212 dmfe driver should be GLD v2 "compliant"
4646439 dmfe driver should support Davicom DM9102A rev 9
4463714 DM9102A (-6) chip can overrun buffers even after SW reset of MAC
4498135 dmfe0: PHY 1 Link down / up reported on console
-----------------------------------------------------------------
I applied this patch and did help quite a bit. Prior to this patch, the
interface was cycling every 5 seconds. It is now flapping about 12 times an hour.
-=-=-=-=-=-=-=-=-
It appears that this is a not-uncommon problem for systems that use the dmfe
interface, but I haven't come across any post that indicate that they resolved
it or how they did it.
TIA for any replies, I will summarize with my solution.
