Right, that is what I am saying. But we should probably know when to do it
and when not to, especially if on the exam the mac address is not available
to view in the bridge group or dlsw reachability output.

~I have done several tests based on the limited equipments I
~have. I have done ethernet to ethernet,ethernet to token ring tests.
~
~At the dlsw peers, you can show llc2 brief, show bridge , show
~rif and show dlsw reachability.
~I use ping ipx for quick tests.
~
~When you do show bridge, the address for ethernet is the same
~as what ever you set it to, the mac address of token ring
~device is byte swapped.When you do show llc2 brief and dlsw
~reachability, it is the reverse.
~
~Now come to filtering, if your filter at interface level, just
~follow the show bridge mac address.(ie follow ethernet address
~as per normal, but byte swapped for token ring interface address).
~When you do filtering using DLSW peer, just follow the show
~dlsw reachability mac address.
~( byte swapped for ethernet device mac, follow the token ring
~as per normal).
