Snmptrap reception and sending on openwrt

i want to configure the snmptrapd but i can't find the snmptrapd.conf .
please help me to find an alternative solution to configure the snmptrapd on openwrt

thank you .
But i want to know how to log my traps and handle them.
And should i create the snmptrapd.conf or the config will be done in the snmpd.conf?

assuming that I have not installed this specific software package,

its configuration will certainly go through its configuration file therefore: snmpd.conf

can you help me find the required configuration (using uci)?

or

uci show | grep snmp

thank you.
but i want those configs built in the ubi image
