ORT TATISTICS
Use the Detailed Port Statistics page to display detailed statistics on
network traffic. This information can be used to identify potential problems
with the switch (such as a faulty port or unusually heavy loading).
All values displayed have been accumulated since the last system reboot,
and are shown as counts per second. Statistics are refreshed every 60
seconds by default.

ARAMETERS
These parameters are displayed on the Detailed Port Statistics page:
Receive/Transmit Total
◆
Packets – The number of received and transmitted packets (good
■
and bad).
Octets – The number of received and transmitted bytes (good and
■
bad), including Frame Check Sequence, but excluding framing bits.
Unicast – The number of received and transmitted unicast packets
■
(good and bad).
Multicast – The number of received and transmitted multicast
■
packets (good and bad).
Broadcast – The number of received and transmitted broadcast
■
packets (good and bad).
Pause – A count of the MAC Control frames received or transmitted
■
on this port that have an opcode indicating a PAUSE operation.
Receive/Transmit Size Counters - The number of received and
◆
transmitted packets (good and bad) split into categories based on their
respective frame sizes.
Receive/Transmit Queue Counters - The number of received and
◆
transmitted packets per input and output queue.
Receive Error Counters
◆
Rx Drops - The number of inbound packets which were discarded
■
even though no errors had been detected to prevent their being
delivered to a higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer space.
Rx CRC/Alignment - The number of frames received with CRC or
■
alignment errors.
Rx Undersize - The total number of frames received that were less
■
than 64 octets long (excluding framing bits, but including FCS
octets) and were otherwise well formed.
Rx Oversize - The total number of frames received that were
■
longer than the configured maximum frame length for this port
(excluding framing bits, but including FCS octets) and were
otherwise well formed.
