Table 13-4. Hardware MIB Buffer statistics
Dataplane Statistics
The show hardware stack-unit cpu data-plane statistics command describes the packet types coming
to the CPU. The following example provides detailed RX/TX packet statistics on a per-queue basis. This
allows you to determine if the CPU-bound traffic is internal (“party bus” or IPC traffic) or network control
traffic, which the CPU must process.
