Ether Statistics (Ethernet Statistics) B-B-B
Displays a list of the Ethernet statistics of the LAN port (e1a) such as port name, LAN
address, bytes (running account of how many bytes have been received since last
reset), packets (running account of how many packets have been received since last
reset) and errors received and transmitted, number of disconnects, number of fast
restarts, number of endless and startless packets, and amount of babble.
You may enter Ctrl-r at any time to reset 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 received by the Ethernet port.
Bytes transmitted – Number of bytes transmitted by the Ethernet port.
Packets received – Number of packets transmitted by the Ethernet port and what type
(multicasts, broadcasts, flooded, local origin, queued).
– 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.
Errors – Number of errors transmitted by the Ethernet port and what type (collisions,
M/L/E, deferrals, carrier loss, underflow, buffer). M = multi-collision frames – not counted
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.
Bytes transmitted – Number of bytes transmitted on the Ethernet port.
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.
