-\fBstatus \fIswitch\fR [\fIkey\fR]
-Prints to the console a series of key-value pairs that report the
-status of \fIswitch\fR. If \fIkey\fR is specified, only the key-value
-pairs whose key names begin with \fIkey\fR are printed. If \fIkey\fR is

Prints to the console statistics for each of the flow tables used by

-\fBadd\-flow \fIswitch flow\fR
-Add the flow entry as described by \fIflow\fR to the \fIswitch\fR's
-tables. The flow entry is in the format described in \fBFlow Syntax\fR,
-below.
-.
-.TP
-\fBadd\-flows \fIswitch file\fR
-Add flow entries as described in \fIfile\fR to \fIswitch\fR's
-tables. Each line in \fIfile\fR is a flow entry in the format
-described in \fBFlow Syntax\fR, below.

-Modify the actions in entries from the \fIswitch\fR's tables

-wildcards are not treated as active for matching purposes. See
-\fBFlow Syntax\fR, below, for the syntax of \fIflows\fR.
+.SS "OpenFlow Switch Flow Table Commands"
+.
+These commands manage the flow table in an OpenFlow switch. In each
+case, \fIflow\fR specifies a flow entry in the format described in
+\fBFlow Syntax\fR, below, and \fIfile\fR is a text file that contains
+zero or more flows in the same syntax, one per line.
+.
+.IP "\fBadd\-flow \fIswitch flow\fR"
+.IQ "\fBadd\-flow \fIswitch \fB\- < \fIfile\fR"
+.IQ "\fBadd\-flows \fIswitch file\fR"
+Add each flow entry to \fIswitch\fR's tables.
+.
+.IP "[\fB\-\-strict\fR] \fBmod\-flows \fIswitch flow\fR"
+.IQ "[\fB\-\-strict\fR] \fBmod\-flows \fIswitch \fB\- < \fIfile\fR"
+Modify the actions in entries from \fIswitch\fR's tables that match
+the specified flows. With \fB\-\-strict\fR, wildcards are not treated
+as active for matching purposes.
+.
+.IP "\fBdel\-flows \fIswitch\fR"
+.IQ "[\fB\-\-strict\fR] \fBdel\-flows \fIswitch \fR[\fIflow\fR]"
+.IQ "[\fB\-\-strict\fR] \fBdel\-flows \fIswitch \fB\- < \fIfile\fR"
+Deletes entries from \fIswitch\fR's flow table. With only a
+\fIswitch\fR argument, deletes all flows. Otherwise, deletes flow
+entries that match the specified flows. With \fB\-\-strict\fR,
+wildcards are not treated as active for matching purposes.
+.
+.IP "\fBreplace\-flows \fIswitch file\fR"
+Reads flow entries from \fIfile\fR (or \fBstdin\fR if \fIfile\fR is
+\fB\-\fR) and queries the flow table from \fIswitch\fR. Then it fixes
+up any differences, adding flows from \fIflow\fR that are missing on
+\fIswitch\fR, deleting flows from \fIswitch\fR that are not in
+\fIfile\fR, and updating flows in \fIswitch\fR whose actions, cookie,
+or timeouts differ in \fIfile\fR.
+.
+.IP "\fBdiff\-flows \fIsource1 source2\fR"
+Reads flow entries from \fIsource1\fR and \fIsource2\fR and prints the
+differences. A flow that is in \fIsource1\fR but not in \fIsource2\fR
+is printed preceded by a \fB\-\fR, and a flow that is in \fIsource2\fR
+but not in \fIsource1\fR is printed preceded by a \fB+\fR. If a flow
+exists in both \fIsource1\fR and \fIsource2\fR with different actions,
+cookie, or timeouts, then both versions are printed preceded by
+\fB\-\fR and \fB+\fR, respectively.
+.IP
+\fIsource1\fR and \fIsource2\fR may each name a file or a switch. If
+a name begins with \fB/\fR or \fB.\fR, then it is considered to be a
+file name. A name that contains \fB:\fR is considered to be a switch.
+Otherwise, it is a file if a file by that name exists, a switch if
+not.
+.IP
+For this command, an exit status of 0 means that no differences were
+found, 1 means that an error occurred, and 2 means that some
+differences were found.

-.TP
-\fBdel\-flows \fIswitch \fR[\fIflow\fR]
-Deletes entries from the \fIswitch\fR's tables that match
-\fIflow\fR. When invoked with the \fB\-\-strict\fR option, wildcards are
-not treated as active for matching purposes. If \fIflow\fR is
-omitted and the \fB\-\-strict\fR option is not used, all flows in the
-switch's tables are removed. See \fBFlow Syntax\fR, below, for the
-syntax of \fIflows\fR.

.
.IP "\fBsnoop \fIswitch\fR"
Connects to \fIswitch\fR and prints to the console all OpenFlow
the configured controller is disconnected, no traffic is sent, so
monitoring will not show any traffic.

-.IQ "\fBmonitor \fIswitch\fR [\fImiss-len\fR]"
+.IP "\fBmonitor \fIswitch\fR [\fImiss-len\fR]"
Connects to \fIswitch\fR and prints to the console all OpenFlow
messages received. Usually, \fIswitch\fR should specify a connection
named on \fBovs\-openflowd\fR(8)'s \fB\-l\fR or \fB\-\-listen\fR command line
restricting a match to an IPv6 address prefix. A netmask is specified
as a CIDR block (e.g. \fB2001:db8:3c4d:1::/64\fR).
