Emmanual,
Your conversion is correct.
The MAC conversion is in relation to remote device for network media type. If
the remote host is on a ethernet segment, you will need to convert the given
canonical MAC addr into a Non-canonical MAC addr. If host is on a Token-Ring
segment, you will NOT have to make any MAC addr conversions. If both Ethernet
and Token-Ring are on the same router, you will not have to modify MAC addr
either since router will take care of this chore.
Search the archives for more info on MAC (DLSW) conversion within the last 2
weeks or so..
