Figure 7-3:
SNMP traps scheme.
Main parts:
SNMP Trap : The device sends a trap to a monitoring device; the traps are defined in
a MIB file.
snmptrad : It receives the SNMP trap and manages it.
snmptt : It translates the SNMP trap, classify the information with predefined clauses
and acts accordingly to the rules defined for each SNMP trap type.
Monitoring center : Monitoring software, e.g. Nagios, Icinga, etc, that handles the
traps using snmptt.
Note: The SNMP traps in this device are sent using SNMP v2, due to effi-
ciency, security and simplicity reasons. All traps are sent with snmpinform
that tries to confirm the reception of the trap by the Network Man-
agement System (NMS), and resends the trap until a timeout expires if it
receives no confirmation.
7.2.2.1 Trap objects
The generated traps in the device contain different objects in order to provide general and
specific information about the trigger of the notification.
wrzTrapTime: Contains the time information when the trap was sent.
wrzTrapPrmOID: Contains the OID information of the parameter associated to the
generated trap.
