extcap.exe¶
The network analyzer software Wireshark offers a versatile way to expand the tool with new capture interfaces using so-called external capture plugins (extcap). When used with third-party software such as Vector XL Driver Library or Vector SIL Kit, extcap.exe acts as an external capture plugin and enables access to Ethernet, CAN, CAN-FD and LIN in Wireshark.
Configuration¶
For adding new capture interfaces, the trace.xplorer offers an easy-to-use dialog that can be opened via the menu . Simply select all the interfaces that you want to set up for an existing Wireshark installation. Deselected interfaces will be uninstalled.
To apply the configuration, Wireshark must be restarted.
