How to get SNMP v3 working on Fortianalyzer 7.4.2

[zachzhu]

I have been trying to add SNMP on Fortianalyzer. I am able to get V2 working but unable to get V3 working. It have tried no auth/priv, auth/priv, auth/no priv but none seems to be working. I have followed this guide https://docs.fortinet.com/document/fortianalyzer/7.4.2/administration-guide/62555 and wondering if i might have missed any steps?

Tested it on FAZ 7.2.10 successfully. See the below output.

$ snmpwalk -v3 -l authPriv -u admin -a SHA -A "pass6789" -x AES -X "pass6789" 10.1.0.20 system 
SNMPv2-MIB::sysDescr.0 = STRING: FAZ 
SNMPv2-MIB::sysObjectID.0 = OID: FORTINET-CORE-MIB::fortinet.103.3.64 
SNMPv2-MIB::sysUpTime.0 = Timeticks: (190331448) 22 days, 0:41:54.48 
SNMPv2-MIB::sysContact.0 = STRING:  
SNMPv2-MIB::sysName.0 = STRING: FAZ01
SNMPv2-MIB::sysLocation.0 = STRING:  
SNMPv2-MIB::sysServices.0 = INTEGER: 0

1. Did you open SNMP on the FAZ interface (usually port1)?
2. Also try run the below command on your FAZ to see if SNMP queries are reaching it.

diagnose sniffer packet any "port 161" 4

Hope it helps.
