The snmp trap simulator is an ideal tool provided with LoriotPro for snmp trap simulation and for testing LoriotPro trap filter or any of your trap server. Trap Simulator allows you to forge fake snmpv1 traps or snmpv2c notifications and to send them to any snmp trap receiver.

SNMP Trap simulation is very useful to test your trap filters within LoriotPro and check that the associated actions are well performed. It is difficult on a server with an SNMP agent to force the generation of a Snmp Trap or a snmp v2c notification that is sent when a disk, a power supply a fan fails.
snmp V1 trap versus snmp v2c notification
SNMPv1 traps were defined in RFC 1157, with the following fields:
The standard snmp v1 generic traps are:
In SNMPv2c trap is defined as NOTIFICATION and formatted differently comparing to SNMPv1. It has the following parameters:
Starting the snmp trap simulator
To test a SNMP Trap or snmp v2c notification action, select the service tab of the workspace and call the contextual menu by a right click. Select trap Simulator option.
Load the trap simulator
You access the Trap Simulator Interface.

Sending simulated trap and notification
If you wnat to send a forged snmp v1 trap you can select the address of the source of the trap.
Next enter the address and the community. If you send trap from this LoriotPro to this LoriotPro use the loopback address 127.0.0.1. Check that the community is right if you want to verify a filter set on the trap community in the LoriotPro trap filter.
In the combo box V1 standard trap or in the V1 enterprise and notification list , select the trap or notification that you want to simulate by a double click. The trap name is displayed in the lower text box and the variable bindings field is completed.
Snmptrap Snmp Trap
The V1 list box contains only the SNMP V1 trap except the Enterprise trap (Trap V1 of type 6).
The table column description of snmp v2c notification and snmp v1 trap
The list contain all the SNMP V1 trap (Enterprise) and SNMP V2c notification).

Devices are not able to send all the listed snmp v2c notification or SNMP Trap. You can use the SNMP walker tool to find what MIB files thus trap or notification are supported by a device.
In the example below we select a snmp v2 notification. A snmp v1 trap at the same time.
You can modify the value of the variable bindings in the lower field of the screen. In our exemple the Variable binding object are defined and import from the MIB file. Values were arbitrary set to 145 by LoriotPro but you can change them.
The values should be preceded with one of the type below:
(NU) NULL
(ID) OBJECT ID (OS) OCTET SRTING (IN) INTEGER (IP) IP ADDRESS (CO) COUNTER (GA) GAUGE (TI) TIMETICKS (HS) HEXA OCTET STRING
When you have made your selection, click Send.
Come back to the LoriotPro Event Manager and select the trap tab. The SNMP trap are displayed in the trap tab window. The simulated SNMP trap has also fake variable bindings (varbinds 1 to 10).
If you have defined filter associated to a SNMP trap the associated actions will be executed.
