Some users were still confused by its presence.
- Added support for native VLAN tagging. A new "vlan_mode"
parameter can be set for "port". Possible values: "access",
"trunk", "native-tagged" and "native-untagged".
+ - test-openflowd has been removed. Please use ovs-vswitchd instead.
v1.2.0 - 03 Aug 2011
------------------------
latter is equivalent to the one of the former, but the difference in
name makes the intended use obvious.
-ovs-vswitchd is the most sophisticated of ofproto's clients, but
-ofproto can have other clients as well. test-openflowd, in the
-"tests" directory, is much simpler than ovs-vswitchd. It may be
-easier to initially bring up test-openflowd as part of a port.

lib/entropy.c assumes that it can obtain high-quality random number
seeds at startup by reading from /dev/urandom. You will need to
modify it if this is not true on your platform.

-.\" SSL peer program's name:
-.ds SN ovs\-controller
-.
-.SH NAME
-test\-openflowd \- OpenFlow switch implementation
-.
-.SH SYNOPSIS
-.B test\-openflowd
-[\fIoptions\fR] \fIdatapath\fR \fIcontroller\fR\&...
-.
-.SH DESCRIPTION
-The \fBtest\-openflowd\fR program implements an OpenFlow switch using a
-flow-based datapath. \fBtest\-openflowd\fR connects to one or more
-OpenFlow controllers over TCP or SSL.
-.PP
-For a more powerful alternative to \fBtest\-openflowd\fR, see
-\fBovs\-vswitchd\fR(8). Do not run both daemons at the same time.
-.PP
-The mandatory \fIdatapath\fR argument argument specifies the local
-datapath to relay. It takes the form [\fItype\fB@\fR]\fIname\fR,
-where \fIname\fR is the network device associated with the datapath's
-local port. If \fItype\fR is given, it specifies the datapath
-provider of \fIname\fR, otherwise the default provider \fBsystem\fR is
-assumed.
-.
-.PP
-The optional \fIcontroller\fR arguments specify how to connect to the
-OpenFlow controller or controllers. Each takes one of the following
-forms:
-.
-.so lib/vconn-active.man
-.IP "\fBnone\fR"
-Run without actively maintaining a connection to a remote OpenFlow
-controller. (See the \fB\-\-listen\fR option, under \fBNetworking
-Options\fR below, for another way to make OpenFlow connections to the
-switch.)
-.
-.PP
-When multiple controllers are configured, \fBtest\-openflowd\fR
-connects to all of them simultaneously. OpenFlow 1.0 does not specify
-how multiple controllers coordinate in interacting with a single
-switch, so more than one controller should be specified only if the
-controllers are themselves designed to coordinate with each other.
-(The Nicira-defined \fBNXT_ROLE\fR OpenFlow vendor extension may be
-useful for this.)
-.
-.SS "Contacting Controllers"
-The OpenFlow switch must be able to contact the OpenFlow controllers
-over the network. It can do so in one of two ways:
-.
-.IP out-of-band
-In this configuration, OpenFlow traffic uses a network separate from
-the data traffic that it controls, that is, the switch does not use
-any of the network devices added to the datapath with \fBovs\-dpctl
-add\-if\fR in its communication with the controller.
-.IP
-To use \fBtest\-openflowd\fR in a network with out-of-band control, specify
-\fB\-\-out\-of\-band\fR on the \fBtest\-openflowd\fR command line. The control
-network must be configured separately, before or after \fBtest\-openflowd\fR
-is started.
-.
-.IP in-band
-In this configuration, a single network is used for OpenFlow traffic
-and other data traffic, that is, the switch contacts the controller
-over one of the network devices added to the datapath with \fBovs\-dpctl
-add\-if\fR. This configuration is often more convenient than
-out-of-band control, because it is not necessary to maintain two
-independent networks.
-.IP
-In-band control is the default for \fBtest\-openflowd\fR, so no special
-command-line option is required.
-
-Specify the location of the
-controller on the \fBtest\-openflowd\fR command line as the \fIcontroller\fR
-argument. You must also configure the network device for the OpenFlow
-``local port'' to allow \fBtest\-openflowd\fR to connect to that controller.
-The OpenFlow local port is a virtual network port that \fBtest\-openflowd\fR
-bridges to the physical switch ports. The name of the local port for
-a given \fIdatapath\fR may be seen by running \fBovs\-dpctl show
-\fIdatapath\fR; the local port is listed as port 0 in \fBshow\fR's
-output.
-.
-.IP
-Before \fBtest\-openflowd\fR starts, the local port network device is not
-bridged to any physical network, so the next step depends on whether
-connectivity is required to configure the device's IP address. If the
-switch has a static IP address, you may configure its IP address now
-with a command such as
-.B ifconfig of0 192.168.1.1
-and then invoke \fBtest\-openflowd\fR.
-.IP
-On the other hand, if the switch does not have a static IP address,
-e.g. it obtains its IP address dynamically via DHCP, the DHCP client
-will not be able to contact the DHCP server until the OpenFlow switch
-has started up. Thus, start \fBtest\-openflowd\fR without configuring
-the local port network device, and start the DHCP client afterward.

-OpenFlow controllers.
-.IP
-If this option is omitted, the default datapath ID is taken from the

-purposes and is not guaranteed to be unique and should not be used as
-the primary identifier of the datapath.
-.
-.SS "Networking Options"
-.TP
-\fB\-\-datapath\-id=\fIdpid\fR
-Sets \fIdpid\fR, which must consist of exactly 16 hexadecimal digits,
-as the datapath ID that the switch will use to identify itself to the
-OpenFlow controller.
-.IP
-If this option is omitted, the default datapath ID is taken from the

-randomly generated) in the lower 48 bits and zeros in the upper 16.
-.
-.TP
-\fB\-\-fail=\fR[\fBstandalone\fR|\fBsecure\fR]
-The controller is, ordinarily, responsible for setting up all flows on
-the OpenFlow switch. Thus, if the connection to the controller fails,
-no new network connections can be set up. If the connection to the
-controller stays down long enough, no packets can pass through the
-switch at all.
-.IP
-If this option is set to \fBstandalone\fR (the default),
-\fBtest\-openflowd\fR will
-take over responsibility for setting up flows in the local datapath
-when no message has been received from the controller for three times
-the inactivity probe interval (see below), or 45 seconds by default.
-In this ``fail open'' mode, \fBtest\-openflowd\fR causes the datapath to act
-like an ordinary MAC-learning switch. \fBtest\-openflowd\fR will continue to
-retry connection to the controller in the background and, when the
-connection succeeds, it discontinues its standalone switching behavior.
-.IP
-If this option is set to \fBsecure\fR, then \fBtest\-openflowd\fR will not
-set up flows on its own when the controller connection fails.
-.
-.TP
-\fB\-\-inactivity\-probe=\fIsecs\fR
-When the OpenFlow switch is connected to the controller, the
-switch waits for a message to be received from the controller for
-\fIsecs\fR seconds before it sends a inactivity probe to the
-controller. After sending the inactivity probe, if no response is
-received for an additional \fIsecs\fR seconds, the switch
-assumes that the connection has been broken and attempts to reconnect.
-The default and the minimum value are both 5 seconds.
-.IP
-When fail-open mode is configured, changing the inactivity probe
-interval also changes the interval before entering fail-open mode (see
-above).
-.
-.TP
-\fB\-\-max\-idle=\fIsecs\fR|\fBpermanent\fR
-Sets \fIsecs\fR as the number of seconds that a flow set up by the
-OpenFlow switch will remain in the switch's flow table without any
-matching packets being seen. If \fBpermanent\fR is specified, which
-is not recommended, flows set up by the switch will never
-expire. The default is 15 seconds.
-.IP
-Most flows are set up by the OpenFlow controller, not by the
-switch. This option affects only the following flows, which the
-OpenFlow switch sets up itself:
-.
-.RS
-.IP \(bu
-When \fB\-\-fail=open\fR is specified, flows set up when the
-switch has not been able to contact the controller for the configured
-fail-open delay.
-.
-.IP \(bu
-When in-band control is in use, flows set up to bootstrap contacting
-the controller (see \fBContacting the Controller\fR, above, for
-more information about in-band control).
-.RE
-.
-.IP
-As a result, when both \fB\-\-fail=secure\fR and \fB\-\-out\-of\-band\fR are
-specified, this option has no effect.
-.
-.TP
-\fB\-\-max\-backoff=\fIsecs\fR
-Sets the maximum time between attempts to connect to the controller to
-\fIsecs\fR, which must be at least 1. The actual interval between
-connection attempts starts at 1 second and doubles on each failing
-attempt until it reaches the maximum. The default maximum backoff
-time is 8 seconds.
-.
-.TP
-\fB\-l\fR, \fB\-\-listen=\fImethod\fR
-By default, the switch listens for OpenFlow management connections on a
-Unix domain socket named \fB@RUNDIR@/\fIdatapath\fB.mgmt\fR. This socket
-can be used to perform local OpenFlow monitoring and administration with
-tools such as \fBovs\-ofctl\fR.
-.IP
-This option may be used to override the default listener. The \fImethod\fR
-must be given as one of the passive OpenFlow connection methods listed
-below. This option may be specified multiple times to listen to
-multiple connection methods. If a single \fImethod\fR of \fBnone\fR is
-used, no listeners will be created.
-.
-.RS
-.so lib/vconn-passive.man
-.RE
-.
-.TP
-\fB\-\-snoop=\fImethod\fR
-Configures the switch to additionally listen for incoming OpenFlow
-connections for controller connection snooping. The \fImethod\fR must
-be given as one of the passive OpenFlow connection methods listed
-under the \fB\-\-listen\fR option above. This option may be specified
-multiple times to listen to multiple connection methods.
-.IP
-If \fBovs\-ofctl monitor\fR is used to connect to \fImethod\fR specified on
-\fB\-\-snoop\fR, it will display all the OpenFlow messages traveling
-between the switch and its controller on the primary OpenFlow
-connection. This can be useful for debugging switch and controller
-problems.
-.
-.TP
-\fB\-\-in\-band\fR, \fB\-\-out\-of\-band\fR
-Configures \fBtest\-openflowd\fR to operate in in-band or out-of-band control
-mode (see \fBContacting the Controller\fR above). When neither option
-is given, the default is in-band control.
-.
-.TP
-\fB\-\-netflow=\fIip\fB:\fIport\fR
-Configures the given UDP \fIport\fR on the specified IP \fIip\fR as
-a recipient of NetFlow messages for expired flows. The \fIip\fR must
-be specified numerically, not as a DNS name.
-.IP
-This option may be specified multiple times to configure additional
-NetFlow collectors.
-.
-.SS "Rate-Limiting Options"
-.
-These options configure how the switch applies a ``token bucket'' to
-limit the rate at which packets in unknown flows are forwarded to an
-OpenFlow controller for flow-setup processing. This feature prevents
-a single OpenFlow switch from overwhelming a controller.
-.
-.TP
-\fB\-\-rate\-limit\fR[\fB=\fIrate\fR]
-.
-Limits the maximum rate at which packets will be forwarded to the
-OpenFlow controller to \fIrate\fR packets per second. If \fIrate\fR
-is not specified then the default of 1,000 packets per second is used.
-.IP
-If \fB\-\-rate\-limit\fR is not used, then the switch does not limit the
-rate at which packets are forwarded to the controller.
-.
-.TP
-\fB\-\-burst\-limit=\fIburst\fR
-.
-Sets the maximum number of unused packet credits that the switch will
-allow to accumulate during time in which no packets are being
-forwarded to the OpenFlow controller to \fIburst\fR (measured in
-packets). The default \fIburst\fR is one-quarter of the \fIrate\fR
-specified on \fB\-\-rate\-limit\fR.
-.
-This option takes effect only when \fB\-\-rate\-limit\fR is also specified.
-.
-.SS "Datapath Options"
-.
-.IP "\fB\-\-ports=\fIport\fR[\fB,\fIport\fR...]"
-Ordinarily, \fBtest\-openflowd\fR expects the administrator to create
-the specified \fIdatapath\fR and add ports to it externally with a
-utility such as \fBovs\-dpctl\fR. However, the userspace switch
-datapath is implemented inside \fBtest\-openflowd\fR itself and does
-not (currently) have any external interface for \fBovs\-dpctl\fR to
-access. As a stopgap measure, this option specifies one or more ports
-to add to the datapath at \fBtest\-openflowd\fR startup time. Multiple
-ports may be specified as a comma-separated list or by specifying
-\fB\-\-ports\fR multiple times.

-See \fBINSTALL.userspace\fR for more information about userspace
-switching.
