RMON event traps
The following is an example of how to generate an SNMP trap for an RMON event.
If you want to configure a device to send an SNMP trap when the number of broadcast packets
exceeds 100, do the following:
1. Configure an RMON alarm with an ID of 1 that checks etherStatsBroadcastPkts for Port 1 every
15 seconds to see if it exceeds a specified delta threshold (i.e., a change compared to the last
reading). In every sample, check if etherStatsBroadcastPkts exceeds 100 packets compared to
the last measurement. If it does, send an event (id 1) with “Tom” as the owner name. The event
trigger is re-armed, when the falling-threshold value falls below 30 packets since the last
reading.
Console(config)#rmon alarm 1 1.3.6.1.2.1.16.1.1.1.6.1 15 delta
rising-threshold 100 1 falling-threshold 80 1 owner Tom
The rising and the falling thresholds are used for the presence and absence of one specific
condition, with an oscillation buffer in between (e.g. warning versus no warning, not opposite
events like “too much” and “too little”), and should be near each other to be meaningful. The
data monitored may oscillate between these thresholds over time, triggering multiple events,
e.g. when using the settings of 100 and 80 as in the preceding example.
snTrapStackingChasPwrSupplyFailed
brcdIp.0.167 snChasUnitIndex,
snChasPwrSupplyIndex,
snAgGblTrapMessage Minor The SNMP trap that is generated
when a power supply operational
status changed from normal to
failure for a stacking system.
Sample Trap Message
System: Stack unit
<unitNumber>
Power supply
<snChasPwrSupplyIndex> is
down
snTrapStackingTemperatureWarning
brcdIp.0.171 snChasUnitIndex,
snAgGblTrapMessage Critical The SNMP trap that is generated
when the actual temperature
reading rises from the falling
threshold and reaches the rising
threshold.
Sample Trap Message
System: Stack unit
<unitNumber> Temperature
<actual-temp> C degrees,
warning level
<warning-temp> C degrees
