Replaying at different speeds

You can also replay the traffic at different speeds then it was originally captured. Some examples:

To replay traffic as quickly as possible:

# tcpreplay --topspeed --intf1=eth0 sample.pcap

To replay traffic at a rate of 10Mbps:

# tcpreplay --mbps=10.0 --intf1=eth0 sample.pcap

To replay traffic 7.3 times as fast as it was captured:

# tcpreplay --multiplier=7.3 --intf1=eth0 sample.pcap

To replay traffic at half-speed:

# tcpreplay --multiplier=0.5 --intf1=eth0 sample.pcap

To replay at 25 packets per second:

# tcpreplay --pps=25 --intf1=eth0 sample.pcap

To replay packets, one at a time while decoding it (useful for debugging purposes):

# tcpreplay --oneatatime --verbose --intf1=eth0 sample.pcap
