I am trying to send snmp traps using TLS/DTLS with net-snmp 5.7.2 package. I am unable to see the source and destination address in my trap message. It is showing 'unknown' instead of the address. I used the below command to send the trap.
snmptrap -Ci -v 3 -T our_identity=snmpd -T their_identity=manager tlstcp:{destination_ip}:10162 "" UCD-SNMP-MIB::ucdStart
The trap I received was
2021-01-09 19:11:30 TLSTCP: unknown [TLSTCP: unknown]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (37091491) 4 days, 7:01:54.91 SNMPv2-MIB::snmpTrapOID.0 = OID: UCD-SNMP-MIB::ucdStart
This is my snmptrapd configuration file.
[snmp] localCert manager
certSecName 20 snmpd --sn joecool
authUser log -s tsm joecool
I have tried using '-n' flag in the snmptrapd server to use numeric address instead of attempting hostname lookups but it didn't help. I faced no such issue while using snmp v2 or snmp v3 (usm) for sending traps.
