9.7 Multiple PF ‐ PXE Boot
Using the
sfboot
command line utility v4.5.0 (or later version) it is possible to PXE
boot when multiple Physical Functions have been enabled. The primary function on
each port (PF0/PF1) is a privileged function and can be selected for configuration.
Other PFs inherit from their privileged function ‐ so, for example, with two physical
ports and 2 PFs per port:
• PF0 and PF2 will have the same boot ‐ type
• PF1 and PF3 will have the same boot ‐ type
Configuration of non ‐ privileged functions is not currently supported.
In the following example 2 PFs (and 2 VFs) are enabled for each physical interface.
