Explanation of Drop code and Module-ID Values in Packet Capture Output (SonicOS Enhanced 5.9.0

Description

Explanation of Drop code and Module-ID Values in Packet Capture Output (SonicOS Enhanced 5.9.0.6-3o firmware)

Resolution

When viewing output on the System > Packet Capture page, there are two fields that display potentially useful diagnosticinformation in numeric format. The Module-ID field provides information on the specific area of the firewall (UTM) appliance'sfirmware that handled a particular packet. The Drop-Code field provides a reason why the appliance dropped a particularpacket. This article provides a list of the Module-ID and Drop-Code numbers along with their meanings.

Please Note: The following Drop Codes were extracted from SonicOS Enhanced 5.9.0.6-3o  firmware version. These codes may change when a new firmware is available. If unsure, please contact SonicWall support.
