RE: bit ordering of MAC address

That command (and article) has to do with ethernet networks and token
ring networks natively bridged together (i.e. without DLSW in the middle
anywhere). I don't believe it's necessary at all in DLSW networks.

The command will "fix" things on ARP replies which is where you would
find a mismatch of canonical and non-canonical addresses hindering
reachability. In DLSW, you don't flood ARPs through the network, you
exchange ICANREACH or CANUREACH requests between the peers who would
already have handled swapping the bit order for you.

No it is all automatic. You only need the conversion when you configure
filters.

In the following network ,should I use some command to translate the
canonical to non-canonical ? Resume I the dls's peer setting is ok.

    To0--Router--Eth0
or To0--Router--WAN--Router--Eth0

Thanks alot
