Platform and Infrastructure
- Transfer files from USB (NFX150, NFX250 NextGen,
and NFX350 devices)—Starting in Junos OS Release 21.1R1, you can transfer files from
USB to NFX devices by enabling the USB pass-through feature. To enable this feature, use the
set system services usb-pass-throughcommand. Built-in LTE functionality does not work after you enable the USB pass-through feature.[See Supporting File Transfer from USB on NFX150 Devices, Supporting File Transfer from USB on NFX250 NextGen Devices, and Supporting File Transfer from USB on NFX350 Devices.]
- Virtual port peering (NFX250 NextGen and NFX350
devices)—Starting in Junos OS Release 21.1R1, you can configure the virtual port peering
(VPP) feature to map a physical port and an interface to a virtualized network function
(VNF), so that if the physical interface becomes inactive, the corresponding virtual
interface also becomes inactive and the status of the physical interface is communicated to
the virtual interface.
The VPP feature is supported only on the Network Functions Virtualization (NFV) backplane.
[See Configuring VNFs on NFX350 Devices and Configuring VNFs on NFX250 NextGen Devices.]
