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.
history def-owner=<string> def-comm=<string>
The statistics command defines the RMON statistics group and the community string
associated with the group.
statistics def-owner=<string>
def-comm=<string>
The alarm command defines the RMON alarm group and the community string
associated with the group.
alarm def-owner=<string> def-comm=<string>
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.
show rmon <stats|hist|event|alarm>
The following command sequence illustrates how to configure RMON groups.
ML2400(rmon)## rmon
ML2400(rmon)## event def-owner=test def-comm=somestring
RMON Event Default Owner is set
RMON Event Default Community is set
