> ASA/FTD SNMPv3 polling may fail using privacy algorithms AES192 or AES256, even after the fix of CSCvv89400. > The failure is observed when polling from third-party NPM tools or SNMP walk applications.
The symptoms are observed under the following conditions: - ASA/FTD SNMP server is configured version 3 and privacy algorithms AES192 or AES256 are used. - Polling from third-party NPM tools and SNMP walk applications.
Use AES128.
When using other tools like Linux netsnmp version 5.9 with AES192/AES256 or Windows SnmpSoft Snmpwalk v1.01 with AES192/AES256 polling is successful.
