How to sniff on a VLAN

When a physical interface is configured with VLAN, the command ' diag sniff packet' cannot be used to sniff the traffic on the VLAN. Does anyone know how to sniff the traffic on a VLAN?

Take a different approach and use a sniffer on the switch that it' s attached to? Sorry not much help but might be something you' d overlooked.

diag sniff packet [vlanname] works for me.

Thanks for the answer. It works. I also asked Fortinet tech support, and they said this is not supported in current version. LI Hou, you should be the Fortinet tech support.
