www.dell.com | support.dell.com 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 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). 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 command configures alarm conditions. To remove an alarm, use the no form of this command. Syntax rmon alarm index variable interval rthreshold fthreshold revent fevent [type type] [startup direction] [owner name] no rmon alarm index • index-The alarm index. (Range: 1 - 65535) • variable-The object identifier of the particular variable to be sampled. • interval-The interval in seconds over which the data is sampled and compared with the rising and falling thresholds. (Range: 1 - 4294967295) • rthreshold-Rising Threshold. (Range: 1 - 4294967295) • fthreshold-Falling Threshold. (Range: 1 - 4294967295) • revent-The Event index used when a rising threshold is crossed .(Range: 1- 65535) • fevent-The Event index used when a falling threshold is crossed. (Range: 1- 65535) • type type-The sampling method for the selected variable and calculating the value to be compared against the thresholds. If the method is absolute, the value of the selected variable is compared directly with the thresholds at the end of the sampling interval. If the method is delta, the selected variable value at the last sample is subtracted from the current value, and the difference compared with the thresholds. 340 RMON Commands
