ML-Series Ether Ports PM Parameters (continued)
Definition
number of octets in length and do not pass the FCS check.
A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check.
A count of successfully transmitted frames on a particular interface for
1
which transmission is inhibited by exactly on collision.
1
A count of frames received on a particular interface that exceed the
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 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.
1
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
1
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
1
between 1024 and 1518 octets in length inclusive (excluding framing bits
but including FCS octets).
1
The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
15.6.3 ML-Series Ethernet Card Performance Monitoring Parameters
Note: 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.
