Ether Statistics (Ethernet Statistics) (continued) B-B-B
Packets transmitted – 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.
– Broadcast – Messages sent to all network destinations.
– Flooded – Information received, then sent out to each of the interfaces.
– Local origin – Locally transmitted packet; e.g. Ping.
– Queued – Packets waiting to be processed.
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.
Disconnects – Number of disconnects on the Ethernet port and what type (disable,
MAU drop, Xmit fail).
– Disable – Transmit error, timed out.
– MAU drop – Transceivers dropped.
– Xmit fail Transmit fail
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 enter Ctrl-r at any time to reset counters.
Port name – 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.
