Though a "thick mode" AP3630 (by design, not under a wireless controller) does support SNMPv3, its effectiveness is somewhat constrained by the minimal number of supported MIBs. This is what we received from a full MIB walk of a lab AP3630:
One of each: sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation, sysServices One for each of three ports: ifIndex, ifDescr, ifAdminStatus, ifOperStatus One of each: etsysPolicyProfileMaxEntries, etsysPolicyProfileNumEntries, etsysPolicyProfileLastChange, etsysPolicyProfileTableNextAvailableIndex, etsysPolicyProfileName, etsysPolicyProfileRowStatus, etsysPolicyProfilePortVidStatus, etsysPolicyProfilePortVid, etsysPolicyProfileRulePrecedence
The values that you are seeking are not apparently available to SNMP.
