The Unified Access Control policy eliminates the need to maintain policies for different access control features However, you need to start a general…

The command fw ctl debug is the standard utility on a Check Point Security Gateway to control kernel debug flags for troubleshooting. To debug the Unified Access Control Policy, the specific kernel module is designated as UP. The -m switch is used to specify this module. The keyword all is used to enable all available debug flags for the specified module, which is necessary for a general, comprehensive debug as requested in the question. Therefore, fw ctl debug -m UP all is the correct and complete syntax.

B. This option contains a typo (ctil instead of ctl) and uses incorrect syntax (+ all flags). The correct keyword to enable all flags is simply all.

C. While fw ctl kdebug is a valid command for kernel debugging, fw ctl debug is the more common and user-friendly command intended for this specific purpose of managing module debugs.

D. The fwm command is used to interact with the Security Management Server process, not for kernel-level debugging on a Security Gateway where the Unified Policy is enforced.

1. Check Point R81.10 CLI Reference Guide, Page 318, "fw ctl debug". The guide specifies the syntax as fw ctl debug [-h] [-v] [-m { | all | none}] .... This officially documents the use of -m and the all keyword.

2. Check Point SecureKnowledge (SK) Article sk112593: "How to debug Unified Policy". This article provides the exact command for the scenario. Under the "Procedure" section, it states: "To enable all debug flags for the UP (Unified Policy) module, run: [Expert@HostName:0]# fw ctl debug -m UP all".

3. Check Point SecureKnowledge (SK) Article sk89940: "How to use the 'fw ctl debug' command". This article details the usage of the fw ctl debug command, explaining that -m is used to specify the kernel module and that all is a valid flag to turn on all debug options for that module.
