Configuring RMON 

Overview 

Remote Network Monitoring (RMON) is an enhancement to SNMP. It enables proactive remote 

monitoring and management of network devices and subnets. An RMON monitor periodically or 
continuously collects traffic statistics for the network attached to a port on the managed device. The 

managed device can automatically send a notification when a statistic crosses an alarm threshold, so the 

NMS does not need to constantly poll MIB variables and compare the results. 
RMON uses SNMP notifications to notify NMSs of various alarm conditions such as broadcast traffic 
threshold exceeded. In contrast, SNMP reports function and interface operating status changes such as 

link up, link down, and module failure. For more information about SNMP notifications, see "Configuring 

SNMP." 
H3C devices provide an embedded RMON agent as the RMON monitor. An NMS can perform basic 
SNMP operations to access the RMON MIB. 

RMON groups 

Among standard RMON groups, H3C implements the statistics group, history group, event group, alarm 
group, probe configuration group, and user history group. H3C also implements a private alarm group, 

which enhances the standard alarm group. The probe configuration group and user history group are 

not configurable from the CLI. To configure these two groups, you must access the MIB. For more 

information about MIB settings for RMON, see 

Comware V7 Platform MIB Companion

. 

Statistics group 

The statistics group samples traffic statistics for monitored Ethernet interfaces and stores the statistics in 

the Ethernet statistics table (ethernetStatsTable). The statistics include: 

•

 

Number of collisions. 

•

 

CRC alignment errors. 

•

 

Number of undersize or oversize packets. 

•

 

Number of broadcasts. 

•

 

Number of multicasts. 

•

 

Number of bytes received. 

•

 

Number of packets received. 

The statistics in the Ethernet statistics table are cumulative sums. 

History group 

The history group periodically samples traffic statistics on interfaces and saves the history samples in the 

history table (etherHistoryTable). The statistics include: 

•

 

Bandwidth utilization. 

•

 

Number of error packets. 

•

 

Total number of packets.
