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. etherHistoryFragments to increment because it counts both runts (which are
normal occurrences due to collisions) and noise hits.
Fragments
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 (AlignmentError). It is normal for
Jabbers
The number of packets received during this sampling interval that were longer than
1518 octets (excluding framing bits but including FCS octets), and 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).
Dropped
The total number of events in which packets were dropped by the probe due to lack of
resources during this sampling interval. This number is not necessarily the number of
packets dropped, it is
just the number of times this condition has been detected.
Collisions
The best estimate of the total number of collisions on this Ethernet segment during this
sampling interval.
5.19.5 rmon alarm
The rmon alarm global configuration command configures alarm conditions. To remove an alarm, use
the no form of this command.
