Viewing RMON Information

The remote monitoring (RMON) specification extends Simple Network
Management Protocol (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 (10Mbps or 100Mbps).
• 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 Right-click the switch's icon in the Device Tree, 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.
