Interface Configuration

Symbol Errors 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
RMON Statistics
Octets Total number of octets of data received on the network. This statistic
can be used as a reasonable indication of Ethernet utilization.
Packets The total number of packets (bad, broadcast and multicast) received.
Broadcast Packets The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
Multicast Packets The total number of good packets received that were directed to this
multicast address.
Undersize Packets 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.
Oversize Packets The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
Fragments The total number of frames received that were less than 64 octets in
length (excluding framing bits, but including FCS octets) and had either
an FCS or alignment error.
Jabbers The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either an
FCS or alignment error.
CRC Align Errors
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
64 Octets The total number of packets (including bad packets) received and
transmitted that were less than 64 octets in length (excluding framing
bits but including FCS octets).
65-127 Octets
128-255 Octets
256-511 Octets
512-1023 Octets
1024-1518 Octets
1519-1536 Octets
The total number of packets (including bad packets) received and
transmitted where the number of octets fall within the specified range
(excluding framing bits but including FCS octets).
Utilization Statistics
Octets Input in kbits per
second
Number of octets entering this interface in kbits per second.
Packets input per second Number of packets entering this interface in packets per second.
