[acvaldez]

Description	This article describes how to capture a range of ports using the diagnose sniffer.
Scope	FortiGate.
Solution	Use case: It is possible to use a sniffer using port-range, when a packet capture is done for VOIP RTP ports, because usually voice provider RTP ports come into range. So when packet analysis is done, it is possible to use port-range on the sniffer.  Steps: Access to the  FortiGate via SSH or via built-in CLI. Then run this command:  diagnose sniffer packet any 'portrange 1000-3000' 6 0 a Output:  On this sniffer, port ranges are captured from 1000 to 3000.  To review and convert packet capture via Wireshark for analysis, refer to this article: Technical Tip: How to import diagnose sniffer packet data.
