## Symptoms

- * When alert destination is configured with SNMP v.3 and AES authentication, no traps are sent.

* Debug of CPD daemon according to [sk86320](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk86320) shows:

  ```
  
  [CPD 29923 4133603648]@HostName[8 Mar  1:39:14] SNMPDistributor::sendSNMPv3Alert: sending trap to 1.1.1.1:162
  [CPD 29923 4133603648]@HostName[8 Mar  1:39:14] SNMPDistributor::sendSNMPv3Alert: failed to send trap to 1.1.1.1:162
  ```

* SNMP-server can not decrypt packets which were sent by threshold_config for SNMP v.3 with DES authentication configured with right configuration of authentication/privacy and correct passwords.

* Wireshark (with right configuration of authentication/privacy and correct passwords on protocol settings) shows errors for such packets:  
  `
  encryptedPDU: Decrypted data not formatted as expected`
