2.3.4. Configuring the fast path

The fast path is the Turbo CG-NAT component in charge of packet processing. To accelerate ethernet NICs, they must be dedicated to the fast path, and the fast path must be started.

1. Dedicate ports to the fast path and start it:

   vrouter> edit running
   vrouter running config# system fast-path
   vrouter running fast-path#! port pci-b0s4
   vrouter running fast-path# port pci-b0s5
   vrouter running fast-path# show config
   fast-path
       enabled true
       port pci-b0s4
       port pci-b0s5
   vrouter running fast-path# commit
   

   Note

   use show state / network-port to see the list of available network ports with PCI ids; it can help choosing the right ports.

2. Check that the fast path has been started (it can take some time):

   vrouter running fast-path# show state
   fast-path
       port pci-b0s5
       port pci-b0s4
       enabled true
