Configuring inter-VDOM link acceleration with NP6 processors

FortiGate units with NP6 processors include NPU VDOM links that can be used to accelerate inter-VDOM link traffic.

  • A FortiGate with two NP6 processors may have two NPU VDOM links, each with two interfaces:
    • npu0_vlink (NPU VDOM link)
      npu0_vlink0 (NPU VDOM link interface)
      npu0_vlink1 (NPU VDOM link interface)
    • npu1_vlink (NPU VDOM link)
      npu1_vlink0 (NPU VDOM link interface)
      npu1_vlink1 (NPU VDOM link interface)

These interfaces are visible from the GUI and CLI. Enter the following CLI command to display the NPU 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 ]

name: npu1_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

 

== [ npu1_vlink1 ]

name: npu1_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

...

By default the NPU VDOM link interfaces are assigned to the root VDOM. To use them 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, 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
