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 PDU Statistics Rx xSTP PDUs 995(0 pps) Tx xSTP PDUs 69551(268 pps) Rx Link Agg PDUs 0(0 pps) Tx Link Agg PDUs 0(0 pps) Rx lldp PDUs 4484(18 pps) Tx lldp PDUs 0(0 pps) Rx cdp PDUs 0(0 pps) Tx cdp PDUs 0(0 pps) BPDU Tunnel MAC 0 ***STP Threshold reached ***Peer Switch detected
The command
clear statistics cpu-pkt can be used to clear the above statistics.
