Assume a eight-core system installed with vCPE . Furthermore, the system is to be provisioned with two guests, one installed with vRouter. You must first provision the data plane with CPU 0 and then provision the guests with unique CPUs.

1. Determine the number of CPUs of the system by entering this command at the terminal prompt: cat /proc/cpuinfo
   The result displays the details for the CPUs.

   
   processor       : 7
   vendor_id       : GenuineIntel
   cpu family      : 6
   model           : 77
   model name      : Intel(R) Atom(TM) CPU  C2758  @ 2.40GHz
   

2. To allow the data plane to use four CPUs, enter this command at the terminal prompt: set system default dataplane cpu-affinity 0-3
3. Restart the system.
4. Display the CPU affinity set on the data plane by entering this command in configuration mode: show system default dataplane cpu-affinity
   A result similar to the following is displayed:

   cpu-affinity 0-3

   The system used in this example has eight CPUs. The first four CPUs are used by the data plane, which enables the guests to use the next four CPUs. If you provision a guest that requires two CPUs, you can define the guest CPU set as 4-5. If you now provision a second guest, you must define the guest CPU set as 6 to make the CPU set unique from the data plane and the first guest.
