Dataplane Statistics
The show hardware stack-unit cpu data-plane statistics command provides insight into the
packet types coming to the CPU. The
show hardware stack-unit cpu party-bus statistics
command displays input and output statistics on the party 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. The objective is to see whether CPU-bound traffic is internal (so-called party
bus or IPC traffic) or network control traffic, which the CPU must process.
