Les,
With mac address filters, 0 = don't care bits
>From CCO:
Let's look at a few more examples:
dlsw icanreach mac-address 4000.3745.0000 mask ffff.ffff.ffff
This command only includes the MAC address 4000.3745.0000. No other MAC
addresses will pass this mask.
dlsw icanreach mac-address 4000.0000.3745 mask ffff.0000.ffff
This command includes all the MAC addresses within the range: 4000.0000.3745
to 4000.FFFF.3745.
