Hello ccielab,
In cisco CD I've found example lsap access-list
! Access list 201 passes NetBIOS frames (command or response)
access-list 201 permit 0xF0F0 0x0001
but in TAC
http://www.cisco.com/warp/public/698/acl200.html
I've found this
NetBIOS traffic uses SAP values 0xF0 (for commands) and 0xF1
(for responses). Typically, network administrators
use these SAP values to filter this protocol.
The access list entry depicted below permits NetBIOS
traffic and denies everything else (remember the implicit "deny all" at the end
of each ACL):
access-list 200 permit 0xF0F0 0x0101
And I don't know what is right ....
