RMON Commands
206 Intel® Blade Server Ethernet Switch Modules SBCEGBESW1 and SBCEGBESW10 CLI Guide
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)
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.
