What is rlDhcpSpoofingServerPorts?
This object is a bitmask (PortList) where each set bit identifies a switch port that is trusted to have a legitimate DHCP server attached to it, as part of the switch's DHCP snooping / anti-spoofing feature. An administrator sets this to designate the uplink port toward the real corporate DHCP server as trusted, so DHCP offers arriving on all other ports get dropped as spoofed. For example, setting only bit 1 (port 1) in rlDhcpSpoofingServerPorts marks port 1 as the sole trusted DHCP server port, causing offers seen on any other port to be blocked.
