For detailed information about how to install, configure and customize the
RMON-based tools for use with RMON, see Using Optivity Analysis 7.0.
Using Optivity LAN with RMON
Optivity LAN offers two tools you can use to monitor network statistics collected
by the Ethernet DCM: Threshold Manager and Fault Correlator. These tools allow
you to set thresholds on integer-based RMON objects and display trap
information when the threshold is exceeded.
Threshold Manager Tool
After you establish a level of performance that you consider normal for your
network, you can set up your system to generate responses whenever your
network performance becomes abnormal.
As well as generating fault information, you can set thresholds that initiate alarms
whenever specified unfavorable network conditions occur. Whenever a threshold
is met or exceeded, the specified event occurs and the alarm is triggered. The
Optivity application allows you to set thresholds specific to a slot or port.
With Threshold Manager, you can perform the following network management
tasks:
• Display thresholds.
• Add, delete, and modify thresholds.
• Define custom thresholds on any MIB object (RMON only).
• Save and load thresholds to and from a file.
• Save thresholds to nonvolatile random-access memory (NVRAM) (RMON
only).
For detailed information about installing the Threshold Manager tool, see
Using Optivity Analysis 7.0.
Fault Correlator Tool
After you set alarm thresholds on RMON variables using the Threshold Manager,
you can use the Fault Correlator tool to decode the traps that are sent to the
network management station.
