Whether bit errors cause MSP switching
Whether bit errors cause MSP switching: The prerequisites for bit errors to trigger MSP switching are as follows: SD switching is enabled, bit errors are excessive, and there is no switching whose priority is higher than that of SD switching. MSP switching priority: Clear switching > Locked switching > Forced switching >SF switching (triggered by signal failures) > SD switching (triggered by bit errors) > Manual switching > Exercise switching. For details, see MSP switching conditions.

Precautions for changing ring MSP to linear MSP on the Metro 3000

Whether extra services can be restored by stopping the protocol after the MSP switching on an MSTP device
Whether extra services can be restored by stopping the protocol after the MSP switching on an MSTP device: Services on the faulty working channel will be interrupted by stopping the protocol after the MSP switching. Then, the extra services on the protection channel will be restored. During this process, you need to pay attention to the severities of services on the working channel and extra services on the protection channel.
