Thanks for the reply. The agent is based on the Net-SNMP 5.1.2. Your reply confirmed that there's not much change in agent side other than to set --with-default-snmp-version=3, to include the V3 mibs such as: SNMP-TARGET-MIB.txt , SNMP-USER-BASED-SM-MIB.txt , SNMP-VIEW-BASED-ACM-MIB.txt, (may be the configure option automatically includes these), and the application - snmpv3, target.
The manager (client) is an inherited in house application to monitor the interface counter, CPU and memory usage. It takes the configuration from front end UI then insert to the schedule for polling by the defined interval constantly. The in house library call the snmp_sess_init , snmp_sess_open , snmp_sess_session , read_objid , snmp_add_null_var , snmp_sess_synch_response , snmp_sess_close etc. to get the values of desired counters. I guess to make it work with V3 the security data such as username, authentic key, and private key (parameters required by V3 application - snmpget, snmpwalk, etc.) are needed and passed to the structure in the pdu, correct? So all I need to do is to find out the V3 specific fields in the pdu structure and fill them up, correct? How about the engine ID, authprotocal, and privprotocal?

The Net-SNMP agent can support all three versions of SNMP. No changes are needed to your MIB module code whatsoever. ^^^^^^^^^^ If you've got a Net-SNMP MIB module that works with SNMPv1 and SNMPv2c, then it will work with SNMPv3 as well. > Normally how long it takes to migrate from V2 to V3? About a minute. Mostly spent creating the necessary SNMPv3 users, and restarting the SNMP agent.
