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 (100Mbps or 1000Mbps).
• Group 2 (History): Records periodic statistical samples from variables
available in the statistics group.
• Group 3 (Alarms): Allows 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 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.
To view RMON statistics
1 In the Device Tree, right-click the switch's icon, then point to RMON.

You can also access RMON features by using LANDesk Network Manager,
or an SNMP application that supports RMON such as OpenView. For more
information about using RMON to monitor the switch, refer to the Intel
Device View Help.
