Managing the VNF Image
To load a VNF image on the device from a remote location, use the file-copy command.
Alternatively, you can use the NETCONF command file-put, to load a VNF image.
NOTE: You must save the VNF image in the /var/third-party/images directory.
Preparing the Bootstrap Configuration
You can bootstrap a VNF by attaching either a CD or a USB storage device that contains
a bootstrap-config ISO file.
A bootstrap configuration file must contain an initial configuration that allows the VNF
to be accessible from an external controller, and accepts SSH, HTTP, or HTTPS
connections from an external controller for further runtime configurations.
An ISO disk image must be created offline for the bootstrap configuration file as follows:
user@jdm>request genisoimage bootstrap-config-filename iso-filename
Launching a VNF
You can launch a VNF by configuring the VNF name, and specifying either the path to an
XML descriptor file or to an image.
While launching a VNF with an image, two VNF interfaces are added by default. These
interfaces are required for management and internal network. For those two interfaces,
the target Peripheral Component Interconnect (PCI) addresses, such as 0000:00:03:0
and 0000:00:04:0 are reserved.
