Setting Affinity for all Virtual Systems (fw ctl affinity -s -d -fwkall)

Use the fw ctl affinity -s -d -fwkall command to assign the specified number of CPU cores to all Virtual Systems at once.

Effect on Multi-queue settings for ixgbe interfaces

The use of use this command to change the number of cores assigned to Virtual Systems, changes the number of cores available for ixgbe interface rx queues. Conversely, when you change the number of cores assigned to ixgbe interface queues, you also change the number of cores assigned to Virtual Systems.

For example, if your SGMs have 16 cores, and you assign 9 cores to Virtual Systems, the remaining 7 cores are available to the ixgbe interfaces.

Syntax

fw ctl affinity -s -d -fwkall <cores>

Example

This example assigns three cores to Firewall instances for all Virtual Systems.

> fw ctl affinity -s -d -fwkall 3

VDevice 0-2 : CPU 0 1 2 - set successfully

Note: You can run this command from the vs0 context only.
