The show hardware stack-unit cpu party-bus statistics command displays input and output statistics on theparty bus, which carries inter-process communication traffic between CPUs.The command output in the following example has been augmented, providing detailed RX/ TX packet statistics on a per-queue basis. Theobjective is to see whether CPU-bound traffic is internal (so-called party bus or IPC traffic) or network control traffic, which the CPU mustprocess.Example of Viewing Dataplane StatisticsDell#show hardware stack-unit 1 cpu data-plane statisticsbc pci driver statistics for device:rxHandle :773noMhdr :0noMbuf :0noClus :0recvd :773dropped :0recvToNet :773rxError :0rxFwdError :0rxDatapathErr :0rxPkt(COS0 ) :0rxPkt(COS1 ) :0rxPkt(COS2 ) :0rxPkt(COS3 ) :0rxPkt(COS4 ) :0rxPkt(COS5 ) :0rxPkt(COS6 ) :0rxPkt(COS7 ) :0rxPkt(COS8 ) :773rxPkt(COS9 ) :0rxPkt(COS10) :0rxPkt(COS11) :0rxPkt(UNIT0) :773transmitted :12698txRequested :12698noTxDesc :0txError :0txReqTooLarge :0txInternalError :0txDatapathErr :0txPkt(COS0 ) :0txPkt(COS1 ) :0txPkt(COS2 ) :0txPkt(COS3 ) :0txPkt(COS4 ) :0txPkt(COS5 ) :0txPkt(COS6 ) :0txPkt(COS7 ) :0txPkt(COS8 ) :0txPkt(COS9 ) :0Debugging and Diagnostics 1055
