fw ctl affinity

fw ctl affinity -s

Description Sets CoreXL affinities when using multiple processors. For an explanation of kernel, daemon and interface affinities, see the R77 Performance Tuning Administration Guide.

fw ctl affinity -s settings are not persistent through a restart of the Security Gateway. If you want the settings to be persistent, either use:

sim affinity (a Performance Pack command)
Or edit the fwaffinity.conf configuration file

To set interface affinities, you should use fw ctl affinity only if Performance Pack is not running. If Performance Pack is running, you should set affinities by using the Performance Pack sim affinity command. These settings will be persistent. If Performance Pack's sim affinity is set to Automatic mode (even if Performance Pack was subsequently disabled), you will not be able to set interface affinities by using fw ctl affinity -s.

Note - The fw ctl affinity command is different for a VSX Gateway and a Security Gateway:

VSX Gateway - Use the -d parameter to save the CoreXL affinity settings after you reboot it

Security Gateway - The CoreXL affinity settings are not saved after you reboot it

Syntax

> fw ctl affinity -s <proc_selection> <cpuid>

<proc_selection> is one of the following parameters:

Parameter	Description
`-p <pid>`	Sets affinity for a particular process, where `<pid>` is the process ID#.
`-n <cpdname>`	Sets affinity for a Check Point daemon, where `<cpdname>` is the Check Point daemon name (for example: `fwd`).
`-k <instance>`	Sets affinity for a kernel instance, where `<instance>` is the instance's number.
`-i <interfacename>`	Sets affinity for an interface, where `<interfacename>` is the interface name (for example: `eth0`).

<cpuid> should be a processing core number or a list of processing core numbers. To have no affinity to any specific processing core, <cpuid> should be: all.

Note - Setting an Interface Affinity will set the affinities of all interfaces sharing the same IRQ to the same processing core. To view the IRQs of all interfaces, run: fw ctl affinity -l -v -a .

Example To set kernel instance #3 to run on processing core #5, run:

> fw ctl affinity -s -k 3 5

fw ctl affinity -l

Description Lists existing CoreXL affinities when using multiple processors. For an explanation of kernel, daemon and interface affinities, see the R77 Performance Tuning Administration Guide.

Syntax

> fw ctl affinity -l [<proc_selection>] [<listtype>]

If <proc_selection> is omitted, fw ctl affinity -l lists affinities of all Check Point daemons, kernel instances and interfaces. Otherwise, <proc_selection> is one of the following parameters:

Parameter	Description
`-p <pid>`	Displays the affinity of a particular process, where `<pid>` is the process ID#.
`-n <cpdname>`	Displays the affinity of a Check Point daemon, where `<cpdname>` is the Check Point daemon name (for example: `fwd)`.
`-k <instance>`	Displays the affinity of a kernel instance, where `<instance>` is the instance's number.
`-i <interfacename>`	Displays the affinity of an interface, where `<interfacename>` is the interface name (for example: `eth0`).

If <listtype> is omitted, fw ctl affinity -l lists items with specific affinities, and their affinities. Otherwise, <listtype> is one or more of the following parameters:

Parameter	Description
`-a`	All: includes items without specific affinities.
`-r`	Reverse: lists each processing core and the items that have it as their affinity.
`-v`	Verbose: list includes additional information.

Example To list complete affinity information for all Check Point daemons, kernel instances and interfaces, including items without specific affinities, and with additional information, run:

> fw ctl affinity -l -a -v
