Optimizing FGCP HA hardware session synchronization with data interface LAGs

Note

The information in this section applies to FGCP HA hardware session synchronization only. FGSP HA hardware session synchronization packets are distributed by the internal switch fabric to the NP7 processors just like normal data traffic.

For optimal performance, the number of interfaces in the data interface LAG used for FGCP HA hardware session synchronization should divide evenly into the number of NP7 processors. This will distribute FGCP HA hardware session synchronization traffic evenly among the NP7 processors.

For example, the FortiGate-4200F has four NP7 processors. For optimum performance, the data interface LAG used for FGCP HA hardware session synchronization should include four or eight data interfaces. This configuration distributes the hardware session synchronization sessions evenly among the NP7 processors.

For a FortiGate-4400F with six NP7 processors, the optimal data interface LAG would include six or twelve data interfaces.

For a FortiGate-3500F with three NP7 processors, the optimal data interface LAG would include three or six data interfaces.

LAGs with fewer interfaces than the number of NP7 processors will also distribute sessions evenly among the NP7 processors as long as the number of data interfaces in the LAG divides evenly into the number of NP7 processors.

For best results, all of the data interfaces in the LAG should be the same type and configured to operate at the same speed. You can experiment with expected traffic levels when selecting the number and speed of the interfaces to add the LAG. For example, if you expect to have a large amount of hardware session synchronization interface traffic, you can add more data interfaces to the LAG or use 25G instead of 10G interfaces for the LAG.
