NP6-offloaded sessions support offloading IPv4 and IPv6 sessions that include most types of traffic shaping. No special traffic shaping configuration is required. However, IPv4 interface-based traffic shaping is supported only on selected FortiGate models and IPv6 interface-based traffic shaping is not supported.
When NP6 or NP6Lite offloading is enabled, the NP6 and NP6Lite processors do not update traffic shaping statistics, including information about packets dropped by traffic shaping. For example, traffic shaping logs and the output of diagnose commands (for example,
diagnose firewall shaper) will show traffic shaping counters as 0.
NP6XLite processors do support updating traffic shaping statistics and log messages and diagnose command output related to traffic shaping should show accurate statistics.
