end The SNMP server says that fgAvVirusDetected is not present. Using the SNMP debug the outputs will show a failure getting the status of fgAvStatsEntry. diagnose deb reset
diagnose deb console timestamp ena
diagnose debug application snmpd -1
diagnose debug flow show console enable
diagnose debug en
To stop the debug use the command:
diagnose deb disable 2025-03-10 17:24:37 snmpd: usm scopedpdu parse: scoped PDU sz=62
