Thanks Michael, Dave, David, Aaron, Hutin and Loris and those who reply before this gets thru the list.
  It looks like IPMP (IP Multipathing) and this doc will help too.

  I have some systems that I want to see if I can setup a more reliable Ethernet by having redundant Ethernet links.  I checked the FAQ and dont see anything there on this topic and thought to ask the list.   I would like to connect one host to TWO DIFFERENT Cisco SWITCHES with one interface active and one waiting to take over.  Is this possible?  I know with interface bonding I can have multiple links go to the same switch, but added speed is not my goal; it is added reliability.  The Cisco switches will have their spanning tree turned on so that there will be multiple paths to each switch without network loops.
  I also have a bit of a slightly off-topic second part to this query: does anyone knows of a Linux implementation of the above as I maintain both system types
  Thanks in advance and I will summarize unless I got no input at all,
Chuck S.
