Device status "Down" but Snmp/Ping up on snmpv3

[areast]

Dear All

By using 0.8.8c with server 2008R2 64bits
Also using cmd.php / Net-snmp
Problem after change the devices from snmp V2 to V3 (sha+Aes128)
1) using Paessler snmp tester , can run test success from server to devices
2) Status "Down" but inside SNMP / Ping has success
3) Some of the devices can be sloved by "Rebuild poller cache"
4) Below are debug log (for SNMP Get Timeout message also tried increase time already)

1) are you able to perform an snmp query with Net-SNMP tools (like snmpwalk) using v3 against those problematic devices using 1.3.6.1.2.1.1.3.0?
2) have you disabled php snmp extension so cacti is forced to use net-snmp?

Dear BSOD2600

Thanks for advise...I have disable php.ini with below step, however is get more devices having trouble

1)edit php.ini => ;extension=php_snmp.dll => restart Apache => rebuild poller cache as well
2)Setting => poller and path shown as screenshot

Now all snmpV3 devices and some of snmpV2 devices are "DOWN"

Is there any missing step by using Net-SNMP? (does it support AES128 as not show AES protocol at -x)

Turn on debug and many message as below

Well another weird problem.....Apache service could not start after re-enable ;extension=php_snmp.dll => extension=php_snmp.dll
Some unknow reason cause by Net-snmp (because unintsall net-snmp) the apache able to restart

Another happen.....all my devices are work fine suddenly with snmpv3 (SHA +AES128) or SNMPv2
MY question is .......does NET-SNMP are necessary needed ? or PHP5.6.3 already able snmpV3 (sha+aes) ?

[BSOD2600]

I dont use snmpv3 so cant speak from experience. however at least in the past php didnt have support for snmpv3, which is why net-snmp must be used instead. http://forums.cacti.net/viewtopic.php?f=6&t=33216
