vlan-lookup-cache {disable | enable}
You can use the following command to enable or disable VLAN lookup (SPV/TPV) caching. Enable this option to optimize performance of offloaded traffic passing through VLAN interfaces.
config system npu
set vlan-lookup-cache {disable | enable}
end
This option is enabled by default. If your FortiGate with NP7 processors is offloading traffic passing through VLANs, VLAN lookup caching should be enabled for optimal performance.
Enabling or disabling vlan-lookup-cache requires a system restart. You should only change this setting during a maintenance window or quiet period.
