Configuring Inter-VDOM link acceleration with NP4 processors
FortiGate units with NP4 processors include inter-VDOM links that can be used to accelerate inter-VDOM link traffic.
• For a FortiGate unit with two NP4 processors there are also two inter-VDOM links, each with two interfaces:
• npu0-vlink
• npu0-vlink0
• npu0-vlink1
• npu1-vlink
• npu1-vlink0
• npu1-vlink1
These interfaces are visible from the GUI and CLI. For a FortiGate unit with NP4 interfaces, enter the following CLI command (output shown for a FortiGate-5001B):
get hardware npu np4 list
ID Model Slot Interface
0 On-board port1 port2 port3 port4
fabric1 base1 npu0-vlink0 npu0-vlink1
1 On-board port5 port6 port7 port8
fabric2 base2 npu1-vlink0 npu1-vlink1
By default the interfaces in each inter-VDOM link are assigned to the root VDOM. To use these interfaces to accelerate inter-VDOM link traffic, assign each interface in a pair to the VDOMs that you want to offload traffic between. For example, if you have added a VDOM named New-VDOM to a FortiGate unit with NP4 processors, you can go to System > Network > Interfaces and edit the npu0-vlink1 interface and set the Virtual Domain to New-VDOM. This results in an inter-VDOM link between root and New-VDOM. You can also do this from the CLI:
config system interface
edit npu0-vlink1
set vdom New-VDOM
end
