The following table describes significant fields shown above:
Field Description
Octets The total number of octets of data (including those in bad packets) received
on the network (excluding framing bits but including FCS octets).
Packets The total number of packets (including bad packets, broadcast packets, and
multicast packets) received.
Broadcast The total number of good packets received and directed to the broadcast
address. This does not include multicast packets.
Multicast The total number of good packets received and directed to a multicast
address. This number does not include packets directed to the broadcast
address.
CRC Align Errors The total number of packets received with a length (excluding framing bits,
but including FCS octets) of between 64 and 1518 octets, inclusive, but with
either a bad Frame Check Sequence (FCS) with an integral number of octets
(FCS Error) or a bad FCS with a non-integral number of octets (Alignment
Error).
Collisions The best estimate of the total number of collisions on this Ethernet segment.
Undersize Pkts The total number of packets received less than 64 octets long (excluding
framing bits, but including FCS octets) and otherwise well formed.
Oversize Pkts The total number of packets received longer than 1518 octets (excluding
framing bits, but including FCS octets) and otherwise well formed.
Fragments The total number of packets received less than 64 octets in length (excluding
framing bits but including FCS octets) and either a bad Frame Check
Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS
with a non-integral number of octets (Alignment Error).
Jabbers The total number of packets received longer than 1518 octets (excluding
framing bits, but including FCS octets), and either a bad Frame Check
Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS
with a non-integral number of octets (Alignment Error).
64 Octets The total number of packets (including bad packets) received that are 64
octets in length (excluding framing bits but including FCS octets).
65 to 127 Octets The total number of packets (including bad packets) received that are
between 65 and 127 octets in length inclusive (excluding framing bits but
including FCS octets).
128 to 255 Octets The total number of packets (including bad packets) received that are
between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
256 to 511 Octets The total number of packets (including bad packets) received that are
between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
