The objective is to see whether CPU-boundtraffic is internal (so-called party bus or IPC traffic) or network control traffic, which the CPU must process.• Display input and output statistics on the party bus, which carries inter-process communication traffic between CPUs.show hardware stack-unit cpu party-bus statisticsDisplaying Dataplane StatisticsDisplaying Party Bus StatisticsDell#show hardware stack-unit 0 cpu data-plane statisticsbc pci driver statistics for device:rxHandle :0noMhdr :0noMbuf :0noClus :0recvd :0dropped :0recvToNet :0rxError :0rxDatapathErr :0rxPkt(COS0) :0rxPkt(COS1) :0rxPkt(COS2) :0rxPkt(COS3) :0rxPkt(COS4) :0rxPkt(COS5) :0rxPkt(UNIT0) :0rxPkt(UNIT1) :0rxPkt(UNIT2) :0rxPkt(UNIT3) :0transmitted :0txRequested :0noTxDesc :0txError :0txReqTooLarge :0txInternalError :0txDatapathErr :0txPkt(COS0) :0txPkt(COS1) :0Z-Series Debugging and Diagnostics 835
