The 'dlsw icanreach mac-exclusive' is as you suspect and works alongside
the 'dlsw icanreach mac-address'. The second command tells connecting
peers that this / these mac-address(es) can be reached, and the first
tells them 'and nothing else!' This has the effect of eliminating
explorers for mac addresses.
The same can then be done for Netbios.

To take it one step further... I haven't messed with dlsw in my configs
yet,
but I did a "dlsw icanreach ?" on one of my test routers and this is
what I
got:
r4(config)#dlsw icanreach ?
mac-address Configure a MAC address that this router can
locally
reach
mac-exclusive Router can ONLY reach the mac addresses that are
user
configured
netbios-exclusive Router can ONLY reach the NetBios names that are
user
configured
netbios-name Configure a NetBios name that this router can
locally
reach
saps Configure a list of SAPs ONLY locally reachable by
this
router
r4(config)#dlsw icanreach
>From this I assume that you can further restrict the traffic that is on
all
of the links. The two "exclusive" commands look like they would keep
any
type of explorers from going over the link - static entries only. Can
anyone confirm if this is the case?

The command is used to notify a DLSW peer a particular MAC that can be
reached via this router. This is designed to keep explorer traffic off
of
the DLSW connections. This is particularly useful at a core site when
many
remote sites require a connection to a mainframe or a FEP. The core
router
will have the "dlsw icanreach mac-address 4000.1234.5678" command in its
config. After DLSW connects, each of teh remotes will know that MAC
4000.1234.5678 is at the core site. Yoou can check this by doing a show
dlsw reachability at the remote side.
