Technical Note: Fortiview bandwidth values not equal to traffic through the FortiGate
Description
Solution
It may be noticed that the values of bandwidth in FortiView do not correspond exactly to the values passing through the FortiGate.
FortiView only reflects the traffic passing through the CPU so the first step is to check whether offload is disabled.
Solution
This issue may be corrected by disabling offloading on the IPv4 Policy:
config firewall policy
edit <policy_id>
set auto-asic-offload disable
next
end
