Tcprewrite add vlan tag description

This option may appear up to 1 times. This option will replay these two files at the same time, one on each interface and inter-mix them using the timestamps in each. The first instance of this argument will rewrite both server and client traffic, but if this argument is specified a second time, it will be used for the client traffic.

Higher numbers increase verbosity. This is done in a way that will not alter packet CRC, and therefore will genrally not affect performance.

Specify a floating point value for the Mbps rate that tcpreplay should send packets at. Allows you to rewrite ethernet frames to add a Please see the tcpdump 1 man page for a complete list of options.

Takes a pair of comma deliminated ethernet MAC addresses which will replace the source MAC address of outbound packets. This option must not appear in combination with any of the following options: Set the DLT value of the output pcap file.

Specify a floating point value for the Mbps rate that tcpreplay should send packets at. This option loads the specified pcap s into RAM before starting to send in order to improve replay performance while introducing a startup performance hit.

If detected, the network driver is bypassed for the execution duration, and network buffers will be written to directly. Preloading can be used with or without --loop and implies --enable-file-cache.

Generally, it only makes sense to use this option with --cachefile. This option may appear up to 2 times. The default number for this option is: By default this value is 8, which means 1 in 8 packets are modified by fuzzing.

This option may appear up to 1 times. The content of the drive is just a readme. This option must not appear in combination with any of the following options: The value of number is constrained to being: The first MAC address will be used for the server to client traffic and the optional second MAC address will be used for the client to server traffic.

A flow is loosely defined as a unique combination of a 5-tuple, i. By default, -n and -l are used. Provide a series of comma deliminated hex values which will be used to rewrite or create the Layer 2 header of the packets.

Takes a comma delimited series of colon delimited CIDR netblock pairs. Note, this option is pretty dangerous! Normally these packets are written to the outputfile unedited so that tcpprep cache files can still be used, but ifyou wish, these packets can be suppressed.

It does the following: The first MAC address will be used for the server to client traffic and the optional second MAC address will be used for the client to server traffic. The first MAC address will be used for the server to client trafficand the optional second MAC address will be used for the client to server traffic.

For example, a value of 30 suggests that if no traffic is seen on a flow for 30 seconds, any subsequent traffic would be considered a new flow, and thereby will increment the flows and flows per second fps statistics.

This option may appear up to times. Higher numbers increase verbosity. Configuring your flow timeouts too high may increase resources required by your flow product. The value of number is constrained to being: This option may improve performance when not using --preload-pcap option, otherwise its only function is to suppress printing.

The first MAC address will be used for the server to client traffic and the optional second MAC address will be used for the client to server traffic. By default, tcpreplay will send packets based on the size of the "snaplen" stored in the pcap file which is usually the correct thing to do.

I tried it and addded VLAN id with tcprewrite (ok), set up a vlan-tagged interface virbr tagged with VLAN id (also ok), then tried tcpreplay to virbr - but no luck. I change vlan on 0/7 from 3 to 5 (now not used RSPAN vlan), enable mirror from 0/7 to 0/1 and get same result as before.

SPAN to 0/7 with changed ip by tcprewrite. From port 0/15 i see only multicast traffic even if it addresses were changed to nonmulticast. #Version: 增加了修改VLAN tag内容. * tcprewrite - 简单的说就是修改2层, 3层, 4层报文头部.
