Hi all,

As I understand, NetBIOS traffic uses SAP values 0xF0 (for commands) and 0xF1
(for responses).
But that is for SSAP only, not DSAP.

But in most of wel-known resources, to filter NetBIOS they use:
    access-list 200 deny 0xF0F0 0x0101

I think above ACL is redundant & does not make points in the LAB, it should
be narrowed to:
    access-list 200 deny 0xF0F0 0x0001

Expecting your comments.

Thanks,
Nguyen Hoang Long
