+.IP "\fBqueue\-stats \fIswitch \fR[\fIport \fR[\fIqueue\fR]]"
+Prints to the console statistics for the specified \fIqueue\fR on
+\fIport\fR within \fIswitch\fR. Either of \fIport\fR or \fIqueue\fR
+or both may be omitted (or equivalently specified as \fBALL\fR). If
+both are omitted, statistics are printed for all queues on all ports.
+If only \fIqueue\fR is omitted, then statistics are printed for all
+queues on \fIport\fR; if only \fIport\fR is omitted, then statistics
+are printed for \fIqueue\fR on every port where it exists.

\fBadd\-flow \fIswitch flow\fR
Add the flow entry as described by \fIflow\fR to the \fIswitch\fR's
When \fBdl_type\fR and \fBnw_proto\fR take other values, the values of
these settings are ignored (see \fBFlow Syntax\fR above).
.
+.IP \fBtable=\fInumber\fR
+If specified, limits the flow manipulation and flow dump commands to
+only apply to the table with the given \fInumber\fR.
+\fInumber\fR is a number between 0 and 31, inclusive.
+.
+If this field is not specified, for \fBadd-flow\fR, \fBadd-flows\fR,
+\fBmod-flows\fR and \fBdel-flows\fR commands, the switch will choose
+the table for these commands to operate on; for \fBdump-flows\fR and
+\fBdump-aggregate\fR commands, statistics are gathered about flows
+from all tables.
+.IP
+When this field is specified in \fBadd-flow\fR, \fBadd-flows\fR,
+\fBmod-flows\fR and \fBdel-flows\fR commands, it will activate a
+Nicira extension to OpenFlow, which as of this writing is only
+known to be implemented by Open vSwitch.

The following shorthand notations are also available:
.
.IP \fBoutput\fR:\fIport\fR
Outputs the packet on the port specified by \fIport\fR.
.
+.IP \fBenqueue\fR:\fIport\fB:\fIqueue\fR
+Enqueues the packet on the specified \fIqueue\fR within port
+\fIport\fR. The number of supported queues depends on the switch;
+some OpenFlow implementations do not support queuing at all.
+.
.IP \fBnormal\fR
Subjects the packet to the device's normal L2/L3 processing. (This
action is not implemented by all OpenFlow switches.)
If outputting to a port that encapsulates the packet in a tunnel and supports
an identifier (such as GRE), sets the identifier to \fBid\fR.
.
+.IP \fBdrop_spoofed_arp\fR
+Stops processing further actions, if the packet being processed is an
+Ethernet+IPv4 ARP packet for which the source Ethernet address inside
+the ARP packet differs from the source Ethernet address in the
+Ethernet header.
+.
+This is useful because OpenFlow does not provide a way to match on the
+Ethernet addresses inside ARP packets, so there is no other way to
+drop spoofed ARPs other than sending every ARP packet to a controller.
+.
+.IP \fBset_queue\fB:\fIqueue\fR
+Sets the queue that should be used to \fIqueue\fR when packets are
+output. The number of supported queues depends on the switch; some
+OpenFlow implementations do not support queuing at all.
+.
+.IP \fBpop_queue\fR
+Restores the queue to the value it was before any \fBset_queue\fR
+actions were applied.
+.
