RMON Commands

Field

Description

 

 

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 etherHistoryFragments to increment because

 

it counts both runts (which are normal occurrences due to collisions) and

 

noise hits.

 

 

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.

 

 

rmon alarm

The rmon alarm Global Configuration mode 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

Parameters

index — Specifies the alarm index. (Range: 1-65535)

variable — Specifies the object identifier of the variable to be sampled.

interval — Specifies the interval in seconds during which the data is sampled and compared with rising and falling thresholds. (Range: 0-2147483647)

rthreshold — Specifies the rising threshold. (Range: 0-2147483647)

fthreshold — Specifies the falling threshold. (Range: 0-2147483647)

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. (Range: 1-65535)
