TRAP is a notification element, that sends trap message (Trap-PDU) from the monitoring system (agent) to the network management base station (SNMP manager).
Trap element supports the formation of SNMP trap messages ver. 1, 2c and 3.
Внимание
Trap element is meaningful only in conjunction with the mechanism of the logic of the monitoring system, that means, if the Trap is not included in any of the existing logic, then an element Trap will not generate and send trap messages.
Managing Traps
It is possible to create, to configure and to delete Trap elements only via the web interface.

where:
- <name> - trap element name in the ctlAllElementName таблицы ctlAllElementsTable;;
- <id> - trap element ID in the ctlAllElementID таблицы ctlAllElementsTable;
You can change the name of the Trap element in the table ctlAllElementsTable
