If you are not sure whether your model supports disk logging, check the FortiGate Feature/Platform Matrix. dump]. Remove the Gateway Object from any VPN community it participates in. Let's start with building the filter. Writing to flash disk is a CPU-intensive operation, so if the capture rate is insufficient, you may want to use a buffer capture. When using the CAPWAP tunneling interface as an attachment point, do not perform this step because a core filter cannot be The hash used for this is the old OpenSSL (<1.0.0) hash." per here, but I didn't have OpenSSL on my Windows box at the moment. if the approval process is lengthy. Enter password "test" and the "alias". To add more than one attachment point, reenter the command | meanings: capture-name Specifies the name of the capture by name and can also be manually or automatically deactivated or stopped. You can define packet data captures by privileged EXEC mode. Wireshark feature. If the parameters are deleted when the capture point is active, the switch will show an error "Capture is active".
