Configuring RMON 
This chapter describes how to configure RMON.  
Overview 
Remote Monitoring (RMON) is an enhancement to SNMP for remote device management and traffic 
monitoring. An RMON monitor, typically the RMON  agent embedded in a network device, periodically 
or continuously collects traffic statistics for the network attached to a port, and when a statistic crosses a 
threshold, logs the crossing event and sends a trap to the management station.  
RMON uses SNMP traps to notify NMSs of...

History group 
The history group defines that the system periodically collects traffic statistics on interfaces and saves the 
statistics in the history record table (ethernetHistory Table). The statistics include bandwidth utilization, 
number of error packets, and total number of packets. 
The history statistics table record traffic statistics  collected for each sampling interval. The sampling 
interval is user-configurable. 
Event group 
The event group defines event indexes and controls the...

 73 
Private alarm group 
The private alarm group calculates the values of alarm variables and compares the results with the 
defined threshold for a more comprehensive alarming function. 
The system handles the private  alarm entry (as defined by the user) in the following ways: 
•   Periodically samples the prialarm variables defined in the prialarm formula. 
•   Calculates the sampled values based on the prialarm formula. 
•   Compares the result with the defined threshold an d generates an...

 74 
•  You can configure multiple history control entries for one interface, but must make sure their entry 
numbers and sampling intervals are different. 
•   On the HP 5500 SI switch, up to 100 histor y entries can be created. On the HP 5500 EI switch, up 
to 1000 history entries can be created. 
•   You can successfully create a history control entry, even if the specified bucket size exceeds the 
history table size supported by the device. However, the effective bucket size will be the actual value...

Step Command Remarks 
3.  Create an entry in the 
alarm table or private 
alarm table. 
• Create an entry in the alarm table:  
rmon alarm  entry -number alarm -variable 
sampling -interval  { absolute  | delta  } 
rising-threshold  threshold -value1  event -entry1  
falling-threshold  threshold -value2  event -entry2  
[ owner  text  ] 
• Create an entry in the private alarm table:  
rmon prialarm  entry-number prialarm-formula 
prialarm-des sampling-interval  { absolute  | 
changeratio  | delta  }...
