Could someone please provide some examples of how to convert an ethernet
canonical Mac to a noncanical DLSW address? I just started studying DLSW and
this is the first major issue I'm having. I'm sure this is just the begining.
On another note, DLSW should be really lite on the CCIE lab with Token Ring
going away (yea!!!! :) Does anyone have any great DLSW notes as pertains to
the new test? (or just good DLSW notes in general?)
Thanks,
Rick

You should know this rule:
DLSw+ always sends data in non-canonical format .
So if you have in your exam the following:
you have a router with ethernet interface - R1- and he asked you to
tell remote peers that station with mac Address X is reachable.
so before putting the mac address in ' dlsw icanreach mac-addr ' command
you should convert this MAC address into non-canonical [ because he gave you
a MAC address of ethernet station, i.e. in canonical format ].
Also in case you want to apply a MAC address to dlsw remote-peer command
you should convert the canonical MAC adress given to you to non-canonical
before applying it in the MAC access-list using the keyword "dmac-out"
in the dlsw remote-peer command.
Hope that clarifies your questions and any confusion .
I'm sure a lot of you know this already but I think it's worth saying. I
figured this out after my NMC class. If you remember the following you never
have to do binary conversion for canonical to non-canonical. Just draw the
chart before doing any conversion. I even find I can do the conversion in my
head now.
