Configuring Spanning Tree STP/RSTP Configurations MCheck Select whether to perform MCheck operations on the port. If a port on an RSTP-enabled/MSTP-enabled device is connected to an STP-enabled device, the port will switch to STP compatible mode and send packets in STP format. MCheck is used to switch the mode of the port back to RSTP/MSTP after the port is disconnected from the STP-enabled device. The MCheck configuration can take effect only once, after that the MCheck status of the port will switch to Disabled. Port Mode Port Role Port Status LAG 2) Click Apply.
