The Statistics sub-menu provides you with an overview of all sent (tx) and received (rx) data packets:

Sent packets

tx-good: The number of successfully sent packets.
tx-unicast: The number of successfully sent unicast packets.
tx-broadcast: The number of successfully sent broadcast packets.
tx-multicast: The number of successfully sent multicast packets.
tx-lostcarrier: The number of lost carrier signals. Indicates a defective medium (for example, cable).
tx-deferred: The number of deferred packets. A packet is deferred if the MAC is busy sending another packet. Deferred packets do not indicate a problem, its just that the CPU queued a transmit packet during transmission of another packet
tx-collision: The number of colliding packets (max. 16).
tx-excesscol: The number of colliding packets (if tx-collision > 16).
tx-latecol: The number of colliding packets that require too much time to be transmitted. If a collision was detected after the 512th bit of the frame being transmitted was reached, a late collision is output.

Received packets

rx-good: The number of successfully received packets.
rx-unicast: The number of successfully received unicast packets.
rx-broadcast: The number of successfully received broadcast packets.
rx-multicast: The number of successfully received multicast packets.
rx-crc-err: The number of received CRC check-sum errors.
rx-align-err: The number of alignment errors (incorrect driver, cable defective) when receiving data packets.
rx-too-short: The number of data packets that are too short during the transmission.
rx-too-long: The number of data packets that are too long during the transmission.
rx-collision: The number of colliding packets (max. 16).
rx-overrun-err / rx-dropped-err: The number of buffer overrun errors when receiving data packets.
rx-queue-overrun: The number of queue overrun errors when receiving data packets.
rx-no-buffer: The number of no buffers when receiving data packets.
rx-frame-dropped: The number of dropped frames. The reason is that the Ethernet driver has no handler for them. This could be because a non matching VLAN-tag, unsupported protocols (e.g. not IP4 IP6, ARP, RARP, PPPOED, PPPOES), etc.

Sent & Received Packets

rx-tx-64: The total number of sent and received packets of 64 Bytes.
rx-tx-64-127: The total number of sent and received packets of between 64 and 127 Bytes.
rx-tx-128-255: The total number of sent and received packets of between 128 and 255 Bytes.
rx-tx-256-511: The total number of sent and received packets of between 256 and 511 Bytes.
rx-tx-512-1023: The total number of sent and received packets of between 512 and 1023 Bytes.
rx-tx-1024: The total number of sent and received packets of 1024 Bytes.


Note: On IP222 IP232 and IP241 the statistics can count the activity on the LAN port, on the PC port or both (default). To select ports for the statistics use the field at "Counter source ports" and press "OK".
