You didn't specify which OS platform.  However, most OSes allow you
to associate an IP address with a NIC via command.  We do this in our
TSM server startup script.  If one NIC fails, you can just
un-associate it from the dead NIC and re-associate with the other
NIC.  No impact to users or DNS that way.

On AIX, this would look something like this:
  /usr/sbin/chdev -l en0 -a alias4=1.2.3.4,255.255.255.192

Hi ALL,

  I have a server that has two interfaces configured (Two IP
addresses as well).

  Without using EtherChannel or any redunancy like that, is there a
way to tell the client to use the 2nd interface incase the first one fails.


  thanks,
  Daad
