   I've never found one either but the process is very simple. Just
   reverse the direction you read each byte. Hence 10110001 in canonical
   (used in Ethernet) becomes 10001101 in non-canonical (Used in Token
   Ring and FDDI) It's a little harder to do directly in HEX because you
   work with four bits at a time instead of 8, so 10110001 which in HEX
   is B1, becomes 8D. You probably won't find anything on Cisco's site,
   because the process is pretty strait forward and doesn't require
   enough effort for one of Cisco's engineers to write up. The only hard
   part about the conversion is knowing which version you are looking at.
   
   While we are on the subject. Someone recently posted that DLSW
   ICANREACH addresses are always entered in non-canonical format, even
   if the host specified is Ethernet attached. This is the first place I
   have heard this (at least that I recall). I only saw the one post on
   this. Can a few of you confirm this. I don't have many DLSW
   references, and nothing I have indicates this fact. (It makes a lot
   of sense though.)
   
   Thanks

   Hi everybody..
   
   
   
   I gave up looking for a reference on the CCO about
   Canonical/Non-Canonical conversion.
   
   Does anybody know if such a link exist ?
   
   
   
   Thanks in advance
   
   George
