Enhanced intelligent process control switch port locking

The intelligent process control switch may implement a locking routine to lock its communication port dedicated for use by devices with known physical addresses, enabling the intelligent process control switch to prevent new, possibly malicious devices from communicating with other devices to which the intelligent process control switch is connected. Further, the intelligent process control switch may implement an address mapping routine to identify a "known pair" of physical and network addresses for each device communicating via the ports of the intelligent process control switch. Thus, even if a new malicious device can spoofing the known physical address to attempt to bypass the locked port, the smart process control switch can detect the malicious device by checking the network address of the malicious device against the expected network address of the "known pair". 智能过程控制交换机可以实现锁定例程以锁定其专门供具有已知物理地址的设备使用的通信端口，使智能过程控制交换机能够防止新的、可能恶意的设备与智能过程控制交换机所连接的其他设备通信。此外，智能过程控制交换机可以实现地址映射例程，以识别经由智能过程控制交换机的端口进行通信的每个设备的物理
