ONFIGURATION
The protocol port security function is short for TCP, UDP protocol port close check
function. If a protocol is not enabled, this function can drop the packet whose
destination IP is the virtual interface IP of the switch, so that it reduces the
unnecessary communications between the modules and the CPU operation of the
fabric, and enhances the anti-interference ability of the switch to the packet.
