+.IP "\fBget\-frags \fIswitch\fR"
+Prints \fIswitch\fR's fragment handling mode. See \fBset\-frags\fR,
+below, for a description of each fragment handling mode.
+.IP
+The \fBshow\fR command also prints the fragment handling mode among
+its other output.

+.IP "\fBset\-frags \fIswitch frag_mode\fR"
+Configures \fIswitch\fR's treatment of IPv4 and IPv6 fragments. The
+choices for \fIfrag_mode\fR are:
+.RS
+.IP "\fBnormal\fR"
+Fragments pass through the flow table like non-fragmented packets.
+The TCP ports, UDP ports, and ICMP type and code fields are always set
+to 0, even for fragments where that information would otherwise be
+available (fragments with offset 0). This is the default fragment
+handling mode for an OpenFlow switch.
+.IP "\fBdrop\fR"
+Fragments are dropped without passing through the flow table.
+.IP "\fBreassemble\fR"
+The switch reassembles fragments into full IP packets before passing
+them through the flow table. Open vSwitch does not implement this
+fragment handling mode.
+.IP "\fBnx\-match\fR"
+Fragments pass through the flow table like non-fragmented packets.
+The TCP ports, UDP ports, and ICMP type and code fields are available
+for matching for fragments with offset 0, and set to 0 in fragments
+with nonzero offset. This mode is a Nicira extension.
+.RE
+.IP
+See the description of \fBip_frag\fR, below, for a way to match on
+whether a packet is a fragment and on its fragment offset.

\fBdump\-flows \fIswitch \fR[\fIflows\fR]
Prints to the console all flow entries in \fIswitch\fR's
Some of these matching possibilities can also be achieved with
\fBdl_vlan\fR and \fBdl_vlan_pcp\fR.

+.IP \fBip_frag=\fIfrag_type\fR
+When \fBdl_type\fR specifies IP or IPv6, \fIfrag_type\fR
+specifies what kind of IP fragments or non-fragments to match. The
+following values of \fIfrag_type\fR are supported:
+.RS
+.IP "\fBno\fR"
+Matches only non-fragmented packets.
+.IP "\fByes\fR"
+Matches all fragments.
+.IP "\fBfirst\fR"
+Matches only fragments with offset 0.
+.IP "\fBlater\fR"
+Matches only fragments with nonzero offset.
+.IP "\fBnot_later\fR"
+Matches non-fragmented packets and fragments with zero offset.

+.IP
+The \fBip_frag\fR match type is likely to be most useful in
+\fBnx\-match\fR mode. See the description of the \fBset\-frags\fR
+command, above, for more details.
