ovs-tcpundump

ovs-tcpundump(1)						Open vSwitch Manual						  ovs-tcpundump(1)

NAME

       ovs-tcpundump - convert ``tcpdump -xx'' output to hex strings

SYNOPSIS

       ovs-tcpundump < file

       Common options:
	      [-h | --help] [-V | --version]

DESCRIPTION

       The ovs-tcpundump program reads tcpdump -xx output on stdin, looking for hexadecimal packet data, and dumps each Ethernet as a single hexa-
       decimal string on stdout.  This format is suitable for use with the ofproto/trace command supported by ovs-vswitchd(8) via ovs-appctl(8).

       At least two -x or -X options must be given, otherwise the output will omit the Ethernet header, which prevents the output from being using
       with ofproto/trace.

OPTIONS

       -h, --help
	      Prints a brief help message to the console.

       -V, --version
	      Prints version information to the console.
