ASAP Ethernet Statistics Parameters (continued)
Meaning
The total number of good packets received that were directed to
a multicast address. Note that this number does not include
packets directed to the broadcast address.
The total number of packets received that were less than
64 bytes in length (excluding framing bits but including FCS
bytes) and had either a bad FCS with an integral number of
bytes (FCS error) or a bad FCS with a nonintegral number of
bytes (alignment error).
Note
The total number of packets (including bad packets) received
that were 64 bytes in length (excluding framing bits but
including FCS bytes).
The total number of packets (including bad packets) received
that were between 65 and 127 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 128 and 255 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 256 and 511 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 512 and 1023 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 1024 and 1518 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The percentage of receive (Rx) line bandwidth used by the
Ethernet ports during consecutive time segments.
Same as Rx Utilization, except calculated over the transmit
(Tx) line bandwidth.
A count of frames received on a particular interface that are not
an integral number of bytes in length and do not pass the FCS
check.
A count of frames received on a particular interface that are an
integral number of bytes in length but do not pass the FCS
check.
Chapter 12
It is entirely normal for etherStatsFragments to
increment. This is because it counts both runts (which
are normal occurrences due to collisions) and noise hits.
