snmptrap
requires (depending on the level of security) the use of fields 4, 5, 8, 9, 10, and 11. Your
SNMP management station(s) will need to be configured to handle these hashed values.
Additionally, in
/etc/snmptraps.conf
you will need to change the setting for V3 to ON. Copy
snmptraps.conf
to
/boot/etc/
after you have made those changes so settings will be saved through
reboots with
cp -a snmptraps.conf /boot/etc/snmptraps.conf
.
You should leave V1V2C set to ON until you verify that you can receive SNMPv3 notifications/in-
forms. Then you can change the value to OFF.
