val. Note that this number is not necessarily the number of packets
dropped, it is just the number of times this condition has been detected.
♦ Octets
The total number of octets of data (including those in bad pack-
ets) received on the network (excluding framing bits but including FCS
octets).
♦ Packets
The number of packets (including bad packets) received dur-
ing this sampling interval.
♦ Broadcast
The number of good packets received during this sampling
interval that were directed to the broadcast address.
♦ Multicast
The number of good packets received during this sampling
interval that were directed to a multicast address. Note that this number
does not include packets addressed to the broadcast address.
♦ CRC Align
The number of packets received during this sampling in-
terval that had a length (excluding framing bits but including FCS octets)
between 64 and 1518 octets, inclusive, but had 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).
♦ Undersize
The number of packets received during this sampling inter-
val that were less than 64 octets long (excluding framing bits but
including FCS octets) and were otherwise well formed.
♦ Oversize
The number of packets received during this sampling interval
that were longer than 1518 octets (excluding framing bits but including
FCS octets) but were otherwise well formed.
♦ Fragment
The total number of packets received during this sampling
interval that were less than 64 octets in length (excluding framing bits
but including FCS octets) had 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). Note that it is entirely nor-
mal for History Fragments to increment. This is because it counts both
runts (which are normal occurrences due to collisions) and noise hits.
