Hello
Could you implement the functionality that would always allow you to keep the sfp port up?
During network management and maintenance, the administrator may need to send traffic from users to a specified server for analysis, recording, and processing. If a server can receive and send packets, there is a possibility that the server forwards user traffic to other devices, causing a security risk. The unidirectional single-fiber communication function can address this issue. A single fiber means that two optical modules are connected by only one fiber, and unidirectional communication means that packets can be sent in only one direction. With this function, a switch can only send but cannot receive packets, and an analysis server can only receive but cannot send packets. The data security on the analysis server is ensured.
After the single-fiber enable command is run on a local interface, the local interface can only send or receive packets through the single fiber. The connection between the optical module’s TX and RX ends determines whether the local interface sends or receives packets. For example, if the TX end of the local optical module is connected to the RX end of the remote optical module, the local device only sends packets and the remote device only receives packets. If the RX end of the local optical module is connected to the TX end of the remote optical module, the local device only receives packets and the remote device only sends packets.
