Ethernet Statistics
B-B-B
Port – Name of port (e1a).
Initialized Ethernet Ports – e1a (there is only one Ethernet port on the MCC card).
LAN Address – LAN (or MAC) address of the Ethernet port.
Management Port – The type of management port (internal/external) and the slot number
of the management port.
Bytes Received – Number of bytes received by the Ethernet port (i.e., a running account
of how many bytes have been received since the last reset).
Packets Received – Running account of packets received by the Ethernet port since the
last reset and what type:
„
„
„
„
„
Multicasts – 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 Received – Number of errors received by the Ethernet port and what type:
„
„
„
„
„
„
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 by the Ethernet port.
Packets Transmitted – Number of packets transmitted by the Ethernet port and what
type (Multicasts, Broadcasts, Flooded, Local Origin, Queued, MTU Exceeded).
Errors Transmitted – Number and type of errors transmitted by the Ethernet port and
what type:
„
Collisions:
– 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.
Deferrals
Carrier Loss
Underflow
Buffer
Disconnects – Number of disconnects on the Ethernet port and what type:
„
„
„
Disable – Transmit error, timed out.
MAU drop – Transceivers dropped.
Xmit fail – Transmit fail.
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.
