Need help on How to send trap directly from a MIB

Hello

I'm very new to snmp.
I just want to write a very simple MIB.

I want to send a trap when the integer ier600LedStatus is updated by a
snmpset command

The traps when I start the snmpd daemon are send correctly than I 
believe that my configuration should work.

I generate the module ierMIB.so in three phase
	- ierMIB.c
	- ier600Trap.c
	- Compile both and link them

I inline the source of the mib and the configuration file with the two
c-files in attachment . Could anybody tell me where I'm wrong


	Thanks

	Bruno
