If you are filtering using a permit clause then you
need to include the NetBIOS functional address for
NetBIOS connectivity.
For example:
access-li 700 permit 10005aabcdef
access-li 700 permit c00000000080
If you are filtering using a deny clause you do not
have to explicitly configure it as in:
access-li 701 deny 10005aabcdef
access-li 701 permit 000000000000 ffffffffffff
