Sure you have enough free RAM to store the entire pcap file(s) in memory or the system will swap and performance will suffer. This option must appear in combination with the following options: loop.Ĭache pcap file(s) the first time they are cached in RAM so that subsequent loops don't incurr any disk I/O latency in order to increase performance. K, -enable-file-cache Enable caching of packets to internal memory. Tcpdump(1) man page for a complete list of options. Be sure to quote the arguments like: -A "-axxx" so that they are not interpreted by tcpreplay. When enabling verbose mode ( -v) you may also specify one or more additional arguments to pass to tcpdump to modify the way packets areĭecoded. This option must appear in combination with the following options: verbose. A string, -decode= string Arguments passed to tcpdump decoder. Only useful if you specified -timer=rdtsc -v, -verbose Print decoded packets via tcpdump to STDOUT. Override the calculated number of RDTSC clicks/usec which is often the speed of the CPU in Mhz. This option takes an integer number as its argument. rdtsc-clicks= number Specify the RDTSC clicks/usec. Running on a non-RTOS and other processes using CPU time. This provides a "fuzz factor" to compensate for Reduce the amount of time we would normally sleep between two packets by the specified number of usec. sleep-accel= number Reduce the amount of time to sleep by specified usec. The default string for this optionĪllows you to select the packet timing method to use: T string, -timer= string Select packet timing mode: select, ioport, rdtsc, gtod, nano, abstime. Print nothing except the statistics at the end of the run If configured with -enable-debug, then you can specify a verbosity level for debugging output. In the range 0 through 5 The default number for this option is: d number, -dbug= number Enable debugging output.

Optionally, the traffic can be split between two interfaces, written to files, filtered and edited in various ways, providing the means to test firewalls,įor more details, please see the Tcpreplay Manual at: Options Speed at which they were recorded, or a specified data rate, up to as fast as the hardware is capable. The basic operation of tcpreplay is to resend all packets from the input file(s) at the This manual page briefly documents the tcpreplay command. Tcpreplay is a tool for replaying network traffic from files saved with tcpdump or other tools which write pcap(3) files. Tcpreplay - Replay network traffic stored in pcap files
