Yes. I'm looking at the 12.1 IOS command reference for DLSW+ at this URL
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/ibm_r/b
rprt2/br1ddlsw.htm#xtocid2979814
dlsw icanreach {mac-exclusive | netbios-exclusive [remote] | mac-address
mac-addr [mask mask] | netbios-name name | saps}
<snip>
mask mask
(Optional) MAC address mask in hexadecimal h.h.h. The "f" value
represents the "don't care" bit and the "0" value represents the
"care" bit. The mask indicates which bits in the MAC address are relevant.
There is a lot of conflicting info out there, but I believe this is right.
