Diagnosing Switch Problems Remote Monitoring (RMON)
OmniSwitch AOS Release 7 Network Configuration Guide June 2013 page 32-39
Sample Display for History Probe
The display shown here identifies RMON Probe 10325’s Owner description and interface location
(Analyzer-p:128.251.18.166 on slot 1, port 35), the total number of History Control Buckets (samples)
requested and granted (2), along with the time interval for each sample (30 seconds) and system-gener-
ated Sample Index ID number (5859). The probe Entry number identifier (10325), probe Flavor (History),
and Status (Active), the amount of time that has elapsed since the last change in status (48 hours, 53
minutes), and the amount of memory allocated to the probe, measured in bytes (601) are also displayed.

Sample Display for Alarm Probe
The display shown here identifies RMON Probe 11235’s Owner description and interface location
(Analyzer-t:128.251.18.166 on slot 1, port 35), as well as the Alarm Rising Threshold of the probe and
Alarm Falling Threshold, maximum allowable values beyond which an alarm is generated and sent to the
Event group (5 and 0, respectively).
Additionally, the corresponding Alarm Rising Event Index number (26020) and Alarm Falling Event
Index number (0), which link the Rising Threshold Alarm and Falling Threshold Alarm to events in the
Event table, are identified. The Alarm Interval, a time period during which data is sampled (10 seconds)
and Alarm Sample Type (delta value—variable) are also shown, as is the Alarm Variable ID number
(1.3.6.1.2.1.16.1.1.1.5.4008). The probe Entry number identifier (11235), probe Flavor (Alarm), Status
(Active), the amount of time that has elapsed since the last change in status (48 hours, 48 minutes), and the
amount of memory allocated to the probe, measured in bytes (1677) are also displayed.
