The statistics on the faceplate PXC ports are maintained only on the data-link layer (Layer 2 MAC). The internal q-tag used for PXC sub-port identification within the router is included in the displayed octet count. The collected statistics represent the combined upstream and downstream traffic carried by the corresponding PXC sub-ports.
For example, in port level statistics output for a faceplate PXC port, the output count represents the upstream and downstream traffic flowing out of the faceplate port while the input count represents the same looped traffic returning into the same port.

Statistics are cleared when a faceplate port is added or removed from the PXC.
Statistics collection to a local file is not supported for faceplate PXC ports.
Queues are not instantiated on the faceplate PXC ports, therefore, the network level (queue) statistics are not maintained in that location.
