Definition
A count of successfully transmitted frames on a particular interface for
2
which transmission is inhibited by exactly on collision.
maximum permitted frame size.
The total number of packets received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise well
formed.
The total number of packets received that were less than 64 octets in length
(excluding framing bits but including FCS octets) and had either a bad FCS
with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
Note
The total number of packets (including bad packets) received that were
64 octets in length (excluding framing bits but including FCS octets).
The total number of packets (including bad packets) received that were
between 65 and 127 octets in length inclusive (excluding framing bits but
including FCS octets).
The total number of packets (including bad packets) received that were
between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
The total number of packets (including bad packets) received that were
between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
The total number of packets (including bad packets) received that were
between 512 and 1023 octets in length inclusive (excluding framing bits but
including FCS octets).
The total number of packets (including bad packets) received that were
between 1024 and 1518 octets in length inclusive (excluding framing bits
but including FCS octets).
The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
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 longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well
formed. Note that for tagged interfaces, this number becomes 1522 bytes.
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad
FCS with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
15.6.4 CE-Series Ethernet Card Performance Monitoring Parameters
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.
