Default Configuration of CoreXL

Important - This default configuration applies only to Security Gateways that do not support Dynamic Balancing of CoreXLClosed Performance-enhancing technology for Security Gateways on multi-core processing platforms. Multiple Check Point Firewall instances are running in parallel on multiple CPU cores. Instances. See Dynamic Balancing of CoreXL Instances.

When you enable CoreXL, the default number of CoreXL Firewall instances is based on the total number of CPU cores.

The default affinityClosed The assignment of a specified CoreXL Firewall instance, VSX Virtual System, interface, user space process, or IRQ to one or more specified CPU cores. setting for all interfaces is automatic when SecureXLClosed Check Point product on a Security Gateway that accelerates IPv4 and IPv6 traffic that passes through a Security Gateway. is enabled. See Allocation of Processing CPU Cores.

Traffic from all interfaces is directed to the CPU cores that run the CoreXL Secure Network Distributor (SND).

The numbers of CoreXL Firewall instances start from zero.

The numbers of CPU cores start from the highest CPU ID allowed by the current Check Point license on your Security GatewayClosed Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources..
