MIB Id not receive by snmp server

Hi All

I just enable snmp traps and sent to external snmp server, but as their checking the Mib Id ( 7779 ) was not received, only recevie 8072 (netsnmp)

as i know, Ib's mib id  is ( 7779 ) as below link

https://docs.infoblox.com/display/NAG8/SNMP+MIB+Hierarchy

and as doc infoblox, they support for netsnmp

https://docs.infoblox.com/display/MAG8/Infoblox+MIBs

my question

1. is it normal behaviour ?

2. why the snmp server just receive id 8072 ( netsnmp ), is it due to, no event trigerred ?
