Is it  similar   to the issue   of   fstab with label=  vs   /dev/dasd...
wrong  device  is being mounted?
  Does this happened when one of NIC is "not available"?

The purpose of those parameters are not to _set_ the MAC address.  They
tell
the system which NIC is to be named eth0, versus eth1, etc.  If you leave
them out, your interface names may change randomly.  It doesn't happen
often, but it could happen.

Subject: Setting the MAC-address


 I am currently working with  SuSE  and RedHat linux.   I notice that in
SuSE   it uses   ifcfg-MAC-address for the interface ,  where RedHat
 it's  in the file.  What is the impact  if   I  leave  out the  HWADDR or
MACADDR. I have 5  NIC ?

  Does the SuSE's way of using  ifcfg-mac-address prevents wrong IP address
being  assign when an interface is down where there are  multiple interface
?
