Description
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. This count
does not include frames received with frame-too-long or frame-too-
short error.
The number of successfully transmitted frames for which transmission
is inhibited by exactly one collision.
A count of successfully transmitted frames for which transmission is
inhibited by more than one collision.
A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
A count of frames for which transmission on a particular interface fails
due to excessive collisions. This counter does not increment when the
interface is operating in full-duplex mode.
A count of frames for which transmission on a particular interface fails
due to an internal MAC sublayer transmit error.
A count of frames received on a particular interface that exceed the
maximum permitted frame size.
For an interface operating at 100 Mb/s, the number of times there was
an invalid data symbol when a valid carrier was present.
For an interface operating in half-duplex mode at 1000 Mb/s, the
number of times the receiving media is non-idle (a carrier event) for a
period of time equal to or greater than slotTime, and during which
there was at least one occurrence of an event that causes the PHY to
indicate
'Data reception error' or 'carrier extend error' on the GMII.
For an interface operating in full-duplex mode at 1000 Mb/s, the
number of times the receiving media is non-idle (a carrier event) for a
period of time equal to or greater than minFrameSize, and during
which there was at least one occurrence of an event that causes the
PHY to indicate 'Data reception error' on the GMII
Total number of octets of data received on the network. This statistic
can be used as a reasonable indication of Ethernet utilization.
The total number of packets (bad, broadcast and multicast) received.
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 this
multicast address.
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.
