Thanks Derek..
That particular post was the reason for me to look for that reference.
here is the mail from Michael Bernico.
I haven't read anything on that subject either...
Thanks

Subject: Re: Canonical/Non-Canonical conversion
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

Subject: Canonical/Non-Canonical conversion
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
