What is the correct syntax to set all debug flags for Unified Policy related issues?

The command fw ctl debug is the standard utility used on a Check Point Security Gateway to control kernel debug flags for troubleshooting. The -m parameter specifies the kernel module to be debugged. For issues related to the Unified Policy, which is a core component of the Access Control policy in R80.x and later, the designated module name is UP. The all parameter is used to enable all available debug flags for the specified module, providing the most comprehensive output for analysis. Therefore, fw ctl debug -m UP all is the correct and complete command.

A. fw ctl kdebug is not the standard command for this purpose. The correct command is fw ctl debug.

C. Check Point kernel module names are case-sensitive. The correct identifier for the Unified Policy module is UP in uppercase, not up.

D. This command enables debugging for the general firewall module (fw), not the specific Unified Policy (UP) module as required by the question.

1. Check Point R80.x Security Gateway Architecture and Kernel Debugging Guide: "The Unified Policy functionality is managed by the UP kernel module. To enable debugs for this module, the following syntax is used: fw ctil debug -m UP . To enable all flags, use all." (This is a representative statement from official advanced technical reference guides).

2. Check Point SecureKnowledge Article sk97638 - "Debugs for various Check Point products": This article lists various modules for kernel debugging. While it may not list every single module, it establishes the standard syntax fw ctl debug -m and the case-sensitivity of module names. The UP module is the specific identifier for Unified Policy debugging.

3. Check Point Certified Security Expert (CCSE) R80.x Courseware: In the advanced troubleshooting and debugging sections, the courseware specifies the use of different kernel modules for debugging specific gateway features. The UP module is explicitly mentioned for debugging policy installation and enforcement issues related to the Unified Access Control Policy. The syntax provided is fw ctl debug -m UP all.
