I also create V3 users with the procedure you indicate. When you stop snmpd, it writes the persistence file. So you cannot edit that file while snmpd is running. The procedure that works for me: 1) Stop snmpd 2) Wait for PID of snmpd to go away, if you have a large number of V3 users, it lengthens the time for the snmpd to write the persistence file. 3) Start snmpd
