Displaying Dataplane Statistics
The show hardware stack-unit cpu data-plane statistics command provides insight into
the packet types coming to the CPU.
As shown in the following example, the show hardware stack-unit cpu data-plane
statistics command output 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.
• Display input and output statistics on the party bus, which carries inter-process communication traffic
between CPUs.
