Displaying Dataplane Statistics
The show hardware linecard {0–2} cpu data-plane statistics command provides information about the packet
types entering a line-card CPU.
As shown in the following example, the show hardware linecard cpu data-plane statistics command output
provides detailed RX/TX packet statistics on a per-queue basis. The output allows you to verify if CPU-bound traffic is internal
(so-called party bus or IPC traffic) or network control traffic, which the CPU must process.
