NetBIOS Filtering Setting
When the NetBIOS filter is enabled, all NetBIOS packets will be filtered from the specified port. Enabling the NetBIOS filter
will create one access profile and create three access rules per port (UDP port numbers 137 and 138 and TCP port number 139).
For Extensive NetBIOS Filter, when it is enabled, all NetBIOS packets over 802.3 frames will be filtered from the specified port.
This command is used to configure the state of the NetBIOS filter. Enabling the Extensive NetBIOS filter will create one access
profile and create one access rule per port (DSAP (Destination Service Access Point) =F0, and SASP (Source Service Access
Point) =F0). To view this window, click Security Management > Filter > NetBIOS Filtering Settings.
