Fragments Jabbers Dropped Collisions 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 etherHistoryFragments to increment because it counts both runts (which are normal occurrences due to collisions) and noise hits. The number of packets received during this sampling interval that were longer than 1632 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). 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. The best estimate of the total number of collisions on this Ethernet segment during this sampling interval. rmon alarm The rmon alarm Global Configuration mode command configures alarm conditions. Use the no form of this command to remove an alarm. Syntax • rmon alarm index variable interval rthreshold fthreshold revent fevent [type type] [startup direction] [owner name] • no rmon alarm index • index - Specifies the alarm index. (Range: 1 - 65535) • variable - Specifies the object identifier of the particular variable to be sampled. • interval - Specifies the interval in seconds during which the data is sampled and compared with rising and falling thresholds. (Range: 1 - 4294967295) • rthreshold - Specifies the rising threshold. (Range: 0 - 4294967295) • fthreshold - Specifies the falling threshold. (Range: 0 - 4294967295) • revent - Specifies the event index used when a rising threshold is crossed. (Range: 1 - 65535) • fevent - Specifies the event index used when a falling threshold is crossed.
