| Severity | Warning |
| Description | PPPoE - Bad host-unique in PADS - dropping packet. Intf:interface_name AC:ac_name |
| Explanation | The adaptive security appliance sent an identifier called the host-unique value to the access controller. The access controller responded with a different host-unique value. The adaptive security appliance is unable to identify the corresponding connection request for this response. The packet was dropped, and connection negotiations were discontinued. |
| User Action | Either the access controller at the service provider is mishandling the host-unique value, or the PADO packet is being forged. |
