On FortiGates with NP7 processors, the following new option is available to enable or disable VLAN accounting:config system npu set vlan-accounting {disable | enable} end VLAN accounting is enabled by default. VLAN accounting on a busy FortiGate with a large number of VLANs can generate large numbers of VLAN lookup (SPV/TPV) messages. In some cases these messages can cause CG-FULL conditions or packet drops, especially on very busy systems. You can use the following command to reduce the number of VLAN accounting massages that are generated by increasing the VLAN accounting interval. config system npu set vlan-acct-interval endThe default VLAN accounting interval is 200 milliseconds. The range is 100 to 10000 milliseconds.
