Hello Umair,
The following is an example of an Event Procedure that will take an event from an Interface model and forward it to the associated Device model using the Device_Mdl_Handle attribute 0x10069 (which contains the value of the device model handle associated with the Interface model) from the Interface model and create a new event on the associated Device model.
0xffff0000 E 50 P " \
CreateEventWithAttributes( \
ReadAttribute( \
{ C CURRENT_MODEL }, \
{ H 0x10069 } ), \
{ H 0xffff0001 }, \
GetEventAttributeList() )"
This would transfer the event 0xffff0000 from the interface model to the device, as event 0xffff0001. All varbinds from the original event 0xffff0000 will also be present on event 0xffff0001 on the device.
