This option may appear up to 1 times. This option takes an integer number as its argument. The value of number is constrained to being:
Automatically enabled for packets modified with --seed, --pnat, --endpoints or --fixlen. This option may appear up to 1 times. This option takes an integer number as its argument. The value of number is constrained to being: Similar to --fixlen, this option will truncate data in packets from Layer 3 and above to be no larger then the MTU.
Note, this option is pretty dangerous! We don't actually check to see if a FCSactually exists in the frame, we just blindly delete the last two bytes.
Hence,you should only use this if you know know that your OS provides the FCS when reading raw packets. Has no effect on IPv4 packets. Packets may be truncated during capture if the snaplen is smaller then thepacket. By default, editing Layer 2 addresses will rewrite broadcast and multicast MAC addresses.
By default, no DLT data link type conversion will be made.
To change the DLT type of the output pcap, select one of the following values: Takes a pair of comma deliminated ethernet MAC addresses whichwill replace the destination MAC address of outbound packets.
The first MAC address will be used for the server to client trafficand the optional second MAC address will be used for the clientto server traffic. Takes a pair of comma deliminated ethernet MAC addresses whichwill replace the source MAC address of outbound packets. 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.
Allows you to rewrite ethernet frames to add a This option must appear in combination with the following options: Apparently this should always be 0, but if you can use any 1 byte value. Set the DLT value of the output pcap file.
This option may appear up to 2 times. Provide a series of comma deliminated hex values which will beused to rewrite or create the Layer 2 header of the packets.
The first instance of this argument will rewrite both serverand client traffic, but if this argument is specified a secondtime, it will be used for the client traffic. Higher numbers increase verbosity.Jun 23, · It can be used for example for vendor add-ons without disturbing Perl's own library directories.

tcpreplay man page. tcpreplay-edit — Replay network traffic stored in pcap files. Synopsis. tcpreplay-edit Allows you to rewrite ethernet frames to add a q header to standard ethernet headers or remove the q VLAN tag information.
add Rewrites the existing ethernet header as an q VLAN header. tcprewrite(1). Bielsko-Biala, Poland; Machida, Japan; Izumo, Japan; San Jose, United States; Blida, Algeria. Jan 19, · What would be the meaning of setting VLAN id on a portgroup to a virtual machine? Would it be a port where all VLANs is forwarded to?
If so, will the Q tag be left on the frame when delivered to the VM? This manual page briefly documents the tcprewrite tranceformingnlp.comrite is a tool to rewrite packets stored in pcap(3) file format,such as crated by tools such as tcpdump(1) and ethereal(1).Once a pcap file has had it's packets rewritten, they can be replayed backout on the network using tcpreplay(1).
