9.4 SNMP TRAP MONITORING
An SNMP trap allows an element, such as the AireLink™ system, to contact network management when
there is a significant event. This is done via unsolicited SNMP messages. For example, if the AireLink
unit reaches a critical RSSILow threshold value, an SNMP trap will be sent to the computer with the
message that the unit has reached the RSSILow value. When the RSSILow conditions resolves the
montoring computer will receive an RSSINormal message via a different trap message.
The system can send out 10 different traps and they are listed in the p1Traps folder under the lpcomm
MIB tree. Figure 9-5 below shows the location in the MIB tree. The meaning of then traps can easily
be derived from the trap name like RSSILow or TemperatureHigh tap. The MIB file list more details
regarding the traps.
