"Remember that entries in show dlsw reach appear in non-canonical format
..."
So let's try an experiment:
-----
r1#sh run | include dlsw icanreach
dlsw icanreach mac-address 00e0.b05a.e74d mask ffff.ffff.ffff
r1#
r2#sh dlsw reachability
DLSw Local MAC address reachability cache list
Mac Addr status Loc. port rif
DLSw Remote MAC address reachability cache list
Mac Addr status Loc. peer
00e0.b05a.e74d UNCONFIRM REMOTE 10.1.1.1(2065)
DLSw Local NetBIOS Name reachability cache list
NetBIOS Name status Loc. port rif
DLSw Remote NetBIOS Name reachability cache list
NetBIOS Name status Loc. peer
r2#
-----
Note that the "sh dlsw reachability" output is displaying what it thinks
is a non-canonical address. This mac address is exactly the same as the
one I configured on r1. IOS did *not* do any conversion. From this we
have to conclude the engineer must do the conversion, if necessary.
If the mac address is from a token ring interface, no conversion is
necessary.
If the mac address is from an ethernet interface (canonical) then you
must convert it to non-canonical format prior to using it in a DLSW
filter.
