Configuring Inter-VDOM link acceleration with NP6 processors
FortiGate units with NP6 processors include inter-VDOM links that can be used to accelerate inter-VDOM link traffic.
• For a FortiGate unit with two NP6 processors there are two accelerated 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 NP6 interfaces, enter the following CLI command to display the NP6-accelerated inter-VDOM links:
get system interface
...
== [ npu0_vlink0 ]
name: npu0_vlink0 mode: static ip: 0.0.0.0 0.0.0.0 status: down netbios-forward: disable type: physical sflow-sampler: disable explicit-web-proxy: disable explicit-ftp-proxy: disable mtu-override: disable wccp: disable drop-overlapped-fragment: disable drop-fragment: disable
== [ npu0_vlink1 ]
name: npu0_vlink1 mode: static ip: 0.0.0.0 0.0.0.0 status: down netbios-forward: disable type: physical sflow-sampler: disable explicit-web-proxy: disable explicit-ftp-proxy: disable mtu-override: disable wccp: disable drop-overlapped-fragment: disable drop-fragment: disable
== [ 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 the 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 accelerated 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
