Ethernet Stats (Ethernet Statistics) B-B-B
Displays a list of the Ethernet statistics of the LAN port (e1a).
The counters increment in real time and you may enter Ctrl-r at any time to reset the
counters.
Port – Type of port (e1a).
Initialized Ethernet Ports – e1a (There is only one other net port on the card).
LAN Address – LAN (or MAC) address of the Ethernet port.
Bytes received – Number of bytes have been received by the Ethernet port since the
last reset.
Bytes transmitted – Number of bytes have been transmitted by the Ethernet port since
the last reset.
Packets received – Number of packets transmitted by the Ethernet port since the last
reset and what type.
– Multicast – Single packets copied to a specific subset of network addresses.
– Broadcasts – Messages sent to all network destinations.
– Flooded – Information received, then sent out to each of the interfaces.
– Filtered – Processes or devices that screen incoming information.
– Discarded – Packets discarded.
– VLAN Error – Number of errors transmitted by the VLAN and what type.
Errors – Number of errors transmitted by the Ethernet port and what type.
– M = Multi-collision frames – not counted in this release and always set to 0.
– L = Late collisions – collision detected often; at least 64 bytes have been
transmitted.
– E = Excessive collisions – port tried to send a packet 15 times without success.
– Overruns – No buffer space.
– Bad CRC – Cyclic Redundancy Check.
– Framing – Receiver improperly interprets set of bits within frame.
– Jumbo gram – Ethernet packet too long.
– Overflow – Part of traffic that is not carried.
– Buffer – No buffer space.
Fast restarts – Number of fast restarts and what type (RX off, TX off, Mem err).
Endless Pkt – Number of endless packets received on the Ethernet port.
Startless Pkt – Number of startless packets received on the Ethernet port.
Babble – Number of garbled packets received due to crosstalk.
