Explanation of drop code and module-Id values in packet capture output (SonicOS 6.2.6.0-20n)
Description
When viewing output in 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 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 6.2.6.0-20n firmware version. These codes may change when a new firmware is available. If 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.
