+.IP "\fBofp\-parse\-pcap\fR \fIfile\fR [\fIport\fR...]"
+Reads \fIfile\fR, which must be in the PCAP format used by network
+capture tools such as \fBtcpdump\fR or \fBwireshark\fR, extracts all
+the TCP streams for OpenFlow connections, and prints the OpenFlow
+messages in those connections in human-readable format on
+\fBstdout\fR.
+.IP
+OpenFlow connections are distinguished by TCP port number.
+Non-OpenFlow packets are ignored. By default, data on TCP ports 6633
+and 6653 are considered to be OpenFlow. Specify one or more
+\fIport\fR arguments to override the default.
+.IP
+This command cannot usefully print SSL encrypted traffic. It does not
+understand IPv6.
