Ether Statistics (Ethernet Statistics) (continued) B-B-B
Bytes Transmitted – Number of bytes transmitted on the Ethernet port.
Packets Transmitted – Number of packets transmitted by the Ethernet port and what
type.
H Multicasts – Single packets copied to a specific subset of network addresses.
H Broadcasts – Messages sent to all network destinations.
H Flooded – Information received, then sent out to each of the interfaces.
H Local Origin – Locally transmitted packet; e.g. Ping.
H Queued – Packets waiting to be processed.
Errors – Number of errors transmitted by the Ethernet port and what type.
H 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.
H Deferrals
H Carrier Loss
H Underflow
H Buffer
Disconnects – Number of fast restarts and what type.
H Disable
H MAU Drop
H XMIT Fail (Cable on floor?)
Fast Restarts – Number of fast restarts and what type.
H RX Off
H TX Off
H 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.
HDLC Bus Stats (HDLC Bus Statistics) B-B-C
Displays a list of of the HDLC backplane port statistics for the s1b port (backplane),
bytes received and transmitted, packets received and transmitted, and errors received
and transmitted. (If a high number of errors have been received, the card may have to
be reset.)
You may press Ctrl-r at any time to reset counters.
Port – Port name (s1b).
Bytes received – Number of bytes received on the backplane port.
Bytes transmitted – Number of bytes transmitted on the backplane port.
Packets received – Number of packets received on the backplane port.
Packets transmitted – Number of packets transmitted on the backplane port.
Errors – Number of other receive errors.
Lost – Number of packets not transmitted due to internal congestion.
