Introduction to Kernel Parameters

Kernel parameters let you change the advanced behavior of your Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources..

These are the supported types of kernel parameters:

Type	Description
Integer	Accepts only one integer value.
String	Accepts only a plain-text string.

Important: In Cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing., you must see and configure the same value for the same kernel parameter on each Cluster Member Security Gateway that is part of a cluster.. In VSX Gateway Physical server that hosts VSX virtual networks, including all Virtual Devices that provide the functionality of physical network devices. It holds at least one Virtual System, which is called VS0., the configured values of kernel parameters apply to all existing Virtual Systems and Virtual Routers.

Security Gateway gets the names and the default values of the kernel parameters from these kernel module files:

• $FWDIR/boot/modules/fw_kern_64.o

• $FWDIR/boot/modules/fw_kern_64_v6.o

• $PPKDIR/boot/modules/sim_kern_64.o

• $PPKDIR/boot/modules/sim_kern_64_v6.o
