Statistic Definitions
Transmit OK: The number of valid frames sent from the port.
Underflow Errors: Internal error. A normal ratio of this counter to
the Transmit OK counter is 1% or less.
Exces Coll Errors: Increments when the port unsuccessfully
transmits a packet 16 consecutive times.
Exces Fctrl Errors: Increments when the port applies flow control
16 consecutive times. See page 73 for more information.
Receive EOF: Total number of frames received at this port.
Receive OK: The number of valid frames received at this port.
Overflow Errors: Internal error. A normal ratio of this counter to the
Transmit OK counter is 1% or less.
CRC Errors: The number of packets received that had a length
(excluding framing bits, but including FCS octets) of between 64 and
1518 octets and had a bad Frame Check Sequence (FCS) with either
an FCS Error or an Alignment Error.
Alignment Errors: The number of frames detected that contain
partial octets and don't pass the FCS check.
Runt Errors: The number of frames detected that are less than the
minimum permitted frame size and have a good FCS.
Lost/Fctrl Errors: The number of packets lost (if flow control is
disabled) or number of packets retransmitted by the originator due to
flow control (if flow control is enabled).
Too Long Errors: The number of frames detected that exceed the
maximum permitted frame size.
etherStatsOctets: The number of octets (bytes) of data (including
those in bad packets) received on the network (excluding framing bits
but including FCS octets).
etherStatsPkts: The number of packets received by the port. This is
not a good indication of total network traffic since packet vary in size.
The number of octets gives a better estimate of network traffic.
etherStatsBcastPkts: The number of frames that are detected without
errors and are directed to the broadcast group address. Doesn't include
multicast frames or frames received with Too Long, Runt, FCS, or
Alignment errors.
