OK Rich,
The Token Ring is gone but the conversion between canonical and noncanonical
did not go. There is some saturations when you have to convert. In general,
DLSW+ does most of the conversion between the two formats automatically
without any intervention, depending on the source media and destination
media. If the source is Ethernet, it would convert the canonical format to
noncanonical format. When it reach the destination, it will convert again to
canonical if the media is Ethernet and it will keep it the same if the media
is TR.
Now, when do you need to convert? You need to convert when you are
filtering. All mac addresses in icanreach, icannotreach and mac address
access list MUST BE IN A NONCANONICAL format. That is because dlsw+ does not
convert these mac addresses.
Hope that this would help.
Sam

Subject: MAC address filtering canonical vs non-canonical
I'm confused as to when I should use canonical (ethernet) and when I should
use non-canonical (token ring) addressing. Now that Token Ring is gone for
the lab there still remains some DLSW filtering issues/concerns.
Is it ok to now always use canonical addressing (with Token Ring gone --
I've heard this), or must I convert when I want to create certain filters?
Does anyone have difinitive breakdown on how this works?
Thanks,
Rich
