The statistics in STP/RSTP/MSTP mode include the following items:
• The number of TCN BPDUs, configuration BPDUs, RST BPDUs, and MST BPDUs sent from each port
• The number of TCN BPDUs, configuration BPDUs, RST BPDUs, MST BPDUs, and wrong BPDUs
received on each port
• The number of BPDUs discarded on each port
