GE ML1200 instruction manual Configuring Rmon

CHAPTER 16: SNMP SNMP

16.4Configuring 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 ML1200 Managed Field Switch 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.
