Viewing RMON information
The remote monitoring (RMON) specification extends SNMP functionality to look at traffic patterns on the network instead of merely looking at the traffic for an individual device. The following RMON groups are supported:
•Group 1 (Statistics): Monitors utilization and error statistics for each network segment (10 Mbps or 100 Mbps).
•Group 2 (History): Records periodic statistical samples from variables available in the statistics group.
•Group 3 (Alarms): Enabless you to set a sampling interval and alarm thresholds for statistics. When a threshold is passed, the switch creates an event. For example, you might set an alarm to create an event if switch utilization exceeds 30%.
•Group 9 (Events): Provides notification and tells the switch what to do when an event occurs on the network. Events can send a trap to a receiving station or place an entry in the log table, or both. For example, when the switch experiences an RMON Event, it sends out an Alarm.
The switch also keeps a log that shows a list of the RMON Events and
RMON Alarms that have occurred on the switch.
