Adjusting NP6 HPE BGP, SLBC, and BFD priorities

Use the following command to adjust the priority of BGP, SLBC, and BFD traffic to control whether the NP6 HPE treats these traffic types as high-priority traffic

config system npu

config priority-protocol

set bgp {disable | enable}

set slbc {disable | enable}

set bfd {disable | enable}

end

By default, all options are set to enable and BGP, SLBC, and BFD packets are treated by the HPE as high priority traffic subject to high-priority overflow. In some cases, the overflow can allow excessive amounts of BGP, SLBC, and BFD host traffic that can cause problems such as route flapping and CPU spikes. If you encounter this problem, or for other reasons you can use this command to set BGP, SLBC, or BFD traffic to low priority, bypassing the HPE pri-type-max overflow. For example, if your FortiGate is not processing one or more of these traffic types, you can set them to low priority to limit the amount of the selected type of packets allowed by the HPE.

Changing these traffic types to low priority can cause problems if your FortiGate is actively processing traffic. Fortinet recommends that you make changes with this command during a maintenance window and then monitor your system to make sure its working properly once it gets busy again.
