RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)
The switch provides hardware-based RMON counters in the switch chipset. The switch manager CPU polls these
counters periodically to collect the statistics in a format that complies with the RMON MIB definition.
RMON Groups Supported
The switch supports the following RMON MIB groups defined in RFC 1757:
-
RMON Statistics Group – maintains utilization and error statistics for the switch port being monitored.
-
RMON History Group – gathers and stores periodic statistical samples from the previous Statistics Group.
-
RMON Alarm Group – allows a network administrator to define alarm thresholds for any MIB variable. An alarm can be
associated with Low Threshold, High Threshold, or both. A trigger can trigger an alarm when the value of a specific MIB variable
exceeds a threshold, falls below a threshold, or exceeds or falls below a threshold.
-
RMON Event Group – allows a network administrator to define actions based on alarms. SNMP Traps are generated when
RMON Alarms are triggered. The action taken in the Network Management Station depends on the specific network management
application.
