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.
