[Soekris] Ethernet L2 Address (arp) problem

[Andy Myers]

Chris,

I've seen cases where a port will be failing, and may or may not be detected
by software at
different times.

As an example, let's say you have sis0, sis1, and sis2 with MAC addresses
:58:10, :58:11, and :58:12, respectively.  If :58:10 is failing, perhaps the
next time he boots
it will not be detected - only :58:11 and :58:12 are detected, and will be
seen as sis0 and sis1.  So it may appear that sis0 changed its MAC, but in
fact one port is going down.

Next time you notice the change in address, check and see if your software
is finding all 3 ports on the net4501.

...just a guess.  :)

Regards,
Andy Myers
