Displaying xSTP statistics

To display the information about the packets that are being processed by CPU.

The high CPU utilization rate may not be because of the received xSTP BPDUs. Therefore, need to check the changes in Campus Fabric (SPX) system configuration, and the network topology to bring down the CPU utilization.

Enter the show statistics cpu-pkt command to get the statistic information.

device# show statistics cpu-pkt
