NOTE:
•
The interfaces attached to the VNF are persistent across VNF restarts.
•
If the VNF supports hot-plugging, you can attach the interfaces when
the VNF is in running state. Otherwise, add the interfaces, and then
restart the VNF.
•
To map interfaces to VLAN, you must enable the memory features
hugepages command option.
•
You cannot change the mapping of VNF interface when the VNF is in
running state.
4. To specify the target PCI address for a VNF interface:
user@jdm# set virtual-network-functions vnf-name interfaces interface-name pci-address
target-pci-address
You can use the target PCI address to rename or reorganize interfaces within the VNF.
For example, a Linux-based VNF can use udev rules within the VNF to name the
interface based on the PCI address.
NOTE:
•
The target PCI-address string should be in the following format:
0000:00:<slot:>:0, which are the values for domain:bus:slot:function.
The slot should be different for each VNF interface. The values for
domain, bus, and function should be zero.
•
You cannot change the target PCI-address of VNF interface when the
VNF is in running state.
5. To delete a VNF interface:
user@jdm# delete virtual-network-functions vnf-name interfaces interface-name
user@jdm# commit
