Remote Network Monitoring (RMON) Commands
78-21075-01 Command Line Interface Reference Guide
Field
Description
Oversize
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.
Fragments
Total number of packets received during this
sampling interval that were less than 64 octets in
length (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). It is normal for
etherHistoryFragments to increment because it
counts both runts (which are normal occurrences
due to collisions) and noise hits.
Jabbers
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
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 the
number of times this condition has been detected.
Collisions
Best estimate of the total number of collisions on this
Ethernet segment during this sampling interval.
