What is Kernel according this output?

[jsercard01]

What's the means of Kernel according this output?:

# fw ctl affinity -l
eth1: CPU 4
eth5: CPU 0
eth2: CPU 4
eth3: CPU 0
eth7: CPU 4
Mgmt: CPU 0
Kernel fw_0: CPU 7
Kernel fw_1: CPU 3
Kernel fw_2: CPU 6
Kernel fw_3: CPU 2
Kernel fw_4: CPU 5
Kernel fw_5: CPU 

This device has 8 Virtual CPU, therefore this device shows only six Kernel instances.

I'd like me known why is it?, I honestly don't understand.

Gateway CPUs are necessarily split between two functions:

• Firewall Kernel (fwk, or workers), which perform various security tasks
• Secure Network Distributor (SND), which are assigned to send traffic to/from the NICs

On an 8 core box, the default is a 2/6 split (2 SNDs, 6 workers).
This distribution can be changed either manually (requires a reboot) or, in R80.40+ with Dynamic Workloads, will adjust on the fly. 

You can find more about CoreXL and SecureXL in the community or read the following SK for more details: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...

Hi PhoneBoy

Thanks a lot for your answer, perfect so 6 Kernels that i saw previously are equal to workers, (0 and 4 SNDs and  1,2,3,5,6,7 fw kernel) It's correct?.

I appreciate your support.

Yes, this is the default for an 8 core box.
