dlsw icanreach
To configure a resource that is locally reachable by this router, use
the dlsw icanreach global configuration command. Use the no form of
this command to remove the resource.
dlsw icanreach {mac-exclusive | netbios-exclusive [remote] |
mac-address mac-addr [mask mask] | netbios-name name | saps}
no dlsw icanreach {mac-exclusive | netbios-exclusive [remote] |
mac-address mac-add [mask mask] | netbios-name name | saps}
Syntax Description
mac-exclusive Router can reach only the MAC addresses that are user
configured.
netbios-exclusive Router can reach only the NetBIOS names that are
user configured.
remote (Optional) Gives the NetBIOS workstations (that are local to
the router and that are not already defined in the dlsw icanreach
netbios-name name statement) access to remote servers.
mac-address mac-addr Configures a MAC address that this router can
locally reach.
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.
netbios-name name Configures a NetBIOS name that this router can
locally reach. Wildcards (*) are allowed at the end of the name.
Trailing white spaces are ignored when comparing against an actual
name in a NetBIOS frame.
saps (Optional) Array of SAPs.

p.s. I guess this is one for the CCIGs (lower case g od). I'll
test it if
I can find the time and equipment.

Subject: DLSW clarification on mac address filter/ICANREACH
exchange
Are the masks for mac address filters and ICANREACH commands the
opposite of
each other? I cannot find a good example that explains the
ICANREACH mask.

Vendor code filter - filters explorer packets sent out from router
vendor portion/any portion of Mac address
700-799 48-bit MAC address access list
access-list 704 deny 0260.8c00.0000 0000.00FF.FFFF - deny's 3Com
NICs
access-list 704 permit 0000.0000.0000 FFFF.FFFF.FFFF - permit all
others
dmac-output-list - mac address filter
F's are don't care
0's must match
ICANREACH - will prevent a router from sending out an explorer
packet
because it is learned during the capabilities exchange process.
dlsw icanreach mac-address 0006.e9db.31ce mask ffff.ffff.ffff
F's mush match
