vlan-lookup-cache {disable | enable}

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.

Note

A configuration change that causes a FortiGate to restart can disrupt the operation of an FGCP cluster. If possible, you should make this configuration change to the individual FortiGates before setting up the cluster. If the cluster is already operating, you should temporarily remove the secondary FortiGate(s) from the cluster, change the configuration of the individual FortiGates and then re-form the cluster. You can remove FortiGate(s) from a cluster using the Remove Device from HA cluster button on the System > HA GUI page. For more information, see Disconnecting a FortiGate.
