Labels:text | screenshot | font | black and white OCR: Help File trace [<iface> [off <btio> [<tracefile>]]] Controls packet tracing by the interface drivers. Specific bits enable tracing of the various interfaces and the amount of infor- mation produced. Tracing is controlled on a per-interface basis; without arguments, trace gives a list of all defined interfaces and their tracing status. Output can be limited to a single interface by specifying it, and the control flags can be change by specifying them as well. The flags are given as a hexadecimal number which is interpreted as follows: - Enable tracing of output packets if 1, disable if 0 I - Enable tracing of input packets if 1, disable if 0 T - Controls type of tracing : - Protocol headers are decoded, but data is not displayed 1 - Protocol headers are decoded, and data (but not the headers themselves) are displayed as ASCII characters, 64 characters/line. Unprintable characters are displayed as hyphens. 2 - Protocol headers are decoded, and the entire packet (headers AND data) is also displayed in hexadecimal and ASCII, 16 characters per line. B - Broadcast filter flag. If set, only packets specifically addressed to this node will be traced; broadcast packets will not be displayed. If tracefile is not specified, tracing will be to the console.
