Hello, guys. I want to ask if anyone has encountered the problem of incorrect operation of the branded MFP Sik-module and RouterBoard. The situation is this: if you manually set the speed of 1 Gbps and FullDuplex, the interface stops sending packets and cannot access the device via WinBox. Also, for unknown reasons, partial loss of ping packets is observed when my laptop is running through an SFP module at 1Gbps speed. The approximate value is shown in the screenshot. The switch is controlled by ROS, version 6.43.7. Help what to do ??
