    Description

    When viewing output on the System | Packet Capture page, there are two fields that display potentially useful diagnostic information in numeric format.

    • The Module-ID field provides information on the specific area of the firewall (UTM) appliance's firmware that handled a particular packet.
    • The Drop-Code field provides a reason why the appliance dropped a particular packet.

    This article provides a list of the Module-ID and Drop-Code numbers along with their meanings.

    NOTE: The following Drop-Codes were extracted from SonicOS Enhanced 6.1.1.9-30n firmware version, however these codes may change when a new firmware is available. When unsure please contact SonicWall support.


    NOTE: Drop code numbers may change based on the firmware version, however, the drop code message (description) remains the same.

    Additional drop code articles:

    • How do I resolve drop code "Enforced Firewall Rule"?
    • How do I resolve drop code "Cache Add Cleanup"?
    • How do I resolve drop code "Packet Dropped - Policy Drop"?
    • How do I resolve drop code "IP Spoof"?
    • How do I resolve drop code "IDP Detection"?
