Two types of statistics can be collected on a regular, non-PXC Ethernet port:
Low-level port statistics which provide information about conditions on the data-link layer and physical port, for example, the aggregate number of forwarded and dropped octets or bytes on the data-link layer (Layer 2 MAC), FCS errors, number of collisions, and so on. These statistics can be viewed with the show port port-id command.
Network-level statistics provide information about forwarded and dropped octets or packets on a per-queue level on network ports. These statistics can be viewed with the show port port-id detail command.
Statistics collection ability on the PXC port depends on whether the PXC is port-based or MAC-based (internal).
