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 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.
