Introduction to Kernel Parameters

Kernel parameters let you change the advanced behavior of your Security Gateway.

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, you must see and configure the same value for the same kernel parameter on each Cluster Member.
• In VSX Gateway, 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/modules/fw_kern_64.o
• $FWDIR/modules/fw_kern_64_v6.o
• $PPKDIR/modules/sim_kern_64.o
• $PPKDIR/modules/sim_kern_64_v6.o
