Yes. Here's an example:
sending:
snmptrap -v 2c -c trappy localhost:9162 42 IF-MIB::linkUp ifIndex.42 i 42
ifDescr.42 s 'My Awesome Interface' enterprises.6316.1.42 c 99
enterprises.6316.2.42 3 4242 enterprises.6316.3.42 C 1234567890
snmptrapd output:
2017-06-05 09:21:44 localhost.localdomain [UDP:
[127.0.0.1]:56631->[127.0.0.1]:9162]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (42) 0:00:00.42
SNMPv2-MIB::snmpTrapOID.0 = OID: IF-MIB::linkUp IF-MIB::ifIndex.42 =
INTEGER: 42 IF-MIB::ifDescr.42 = STRING: My Awesome Interface
SNMPv2-SMI::enterprises.6316.1.42 = Counter32: 99
SNMPv2-SMI::enterprises.6316.2.42 = 4242 SNMPv2-SMI::enterprises.6316.3.42
= Counter64: 1234567890
This single trap PDU contains INTEGER, String, Counter32, Integer32, and
Counter64 types in one trap. I believe that is what you mean when you say
"trap values of different types".
