25.Filter Commands
The commands are used to filter packets from the DHCP server and
NetBIOS over TCP/IP and NetBIOS packets.
The DHCP server packet filtering allows you to limit the number of
DHCP servers to be used if there are multiple DHCP servers on the
network. It also can detect unauthorized DHCP servers and log them or
report them to the management server as a SNMP trap.
