MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

16–13

16.4 Configuring RMON

16.4.1 Description

The switch supports RMON (Remote Monitoring) on all connected network segments. This 
allows for troubleshooting and optimizing your network. The MultiLink family of switches 
provides hardware-based RMON counters. The switch manager or a network 
management system can poll these counters periodically to collect the statistics in a 
format that compiles with the RMON MIB definition.

The following RMON groups are supported:

•

Ethernet statistics group

 - maintains utilization and error statistics for the switch 

port being monitored.

•

History group

 - gathers and stores periodic statistical samples from previous 

statistics group.

•

Alarm group

 - allows a network administrator to define alarm thresholds for any 

MIB variable.

•

Log and event group

 - allows a network administrator to define actions based on 

alarms. SNMP traps are generated when RMON alarms are triggered.

16.4.2 Commands

The following RMON communities, when defined, enable the specific RMON group as show 
above. The 

rmon

 command enter the RMON configuration mode to setup RMON groups 

and communities.

rmon

The 

history

 command defines the RMON history group and the community string 

associated with the group.

 command defines the RMON statistics group and the community string 

associated with the group.

def-comm=<string>

The 

alarm

 command defines the RMON alarm group and the community string 

associated with the group.

The 

event

 command defines the RMON event group and the community string 

associated with the group.

event

 def-owner=<string> def-comm=<string>

The 

show rom

 command lists the specific RMON data as defined by the group type.
