4 _Description: Open vSwitch network devices:
5 Choose the network devices that should become part of the Open vSwitch
6 instance. At least two devices must be selected for this machine to be
7 a useful switch. Unselecting all network devices will disable
10 The network devices that you select should not be configured with IP
11 or IPv6 addresses, even if the switch contacts the controller over
12 one of the selected network devices. This is because a running
13 Open vSwitch takes over network devices at a low level: they
14 become part of the switch and cannot be used for other purposes.
16 Template: openvswitch-switch/no-netdevs
18 _Description: No network devices were selected.
19 No network devices were selected for inclusion in the Open vSwitch
20 instance. The switch will be disabled.
22 Template: openvswitch-switch/configured-netdevs
24 _Description: Some Network Devices Have IP or IPv6 Addresses
25 The following network devices selected to be part of the Open vSwitch
26 instance have IP or IPv6 addresses configured:
30 This is usually a mistake, even if the switch contacts the controller over
31 one of the selected network devices. This is because running Open vSwitch
32 takes over network devices at a low level: they become part of the switch
33 and cannot be used for other purposes.
35 If this is an unintentional mistake, move back and fix the selection,
36 or de-configure the IP or IPv6 from these network devices.

40 _Choices: discovery, in-band, out-of-band
42 _Description: Switch-to-controller access method:
43 Open vSwitch must be able to contact the OpenFlow controller over the
44 network. It can do so in one of three ways:
46 discovery: A single network is used for OpenFlow traffic and other
47 data traffic; that is, the switch contacts the controller over one of
48 the network devices selected as Open vSwitch network devices in
49 the previous question. The switch automatically determines the
50 location of the controller using a DHCP request with an
51 OpenFlow-specific vendor option. This is the most common case.
53 in-band: As above, but the location of the controller is manually
56 out-of-band: OpenFlow traffic uses a network separate from the data traffic
57 that it controls. If this is the case, the control network must already
58 be configured on a network device other than one of those selected as
59 an Open vSwitch netdev in the previous question.
61 Template: openvswitch-switch/discover
63 _Description: Preparing to discover controller
64 The setup program will now attempt to discover the OpenFlow controller.
65 Controller discovery may take up to 30 seconds. Please be patient.
67 See ovs-openflowd(8) for instructions on how to configure a DHCP server for
70 Template: openvswitch-switch/discovery-failure
72 _Description: Controller discovery failed.
73 The controller's location could not be determined automatically.
75 Ensure that the OpenFlow DHCP server is properly configured. See
76 ovs-openflowd(8) for instructions on how to configure a DHCP server for
79 Template: openvswitch-switch/discovery-success
82 _Description: Use discovered settings?
83 Controller discovery obtained the following settings:
85 Controller location: ${controller-vconn}
89 Please verify that these settings are correct.
91 Template: openvswitch-switch/switch-ip
94 _Description: Switch IP address:
95 For in-band communication with the controller, the Open vSwitch instance
96 must be able to determine its own IP address. Its IP address may be
97 configured statically or dynamically.
99 For static configuration, specify the switch's IP address as a string.
101 For dynamic configuration with DHCP (the most common case), specify "dhcp".
102 Configuration with DHCP will only work reliably if the network topology
103 allows the switch to contact the DHCP server before it connects to the
106 Template: openvswitch-switch/switch-ip-error
108 _Description: The switch IP address is invalid.
109 The switch IP address must specified as "dhcp" or a valid IP address in
110 dotted-octet form (e.g. "1.2.3.4").
112 Template: openvswitch-switch/controller-vconn
114 _Description: Controller location:
115 Specify how Open vSwitch should connect to the OpenFlow controller. The
116 value should be in form "ssl:IP[:PORT]" to connect to the controller
117 over SSL (recommended for security) or "tcp:IP[:PORT]" to connect over
120 Template: openvswitch-switch/controller-vconn-error
122 _Description: The controller location is invalid.
123 The controller location must be specifed as "ssl:IP[:PORT]" to
124 connect to the controller over SSL (recommended for security) or
125 "tcp:IP[:PORT]" to connect over cleartext TCP.
127 Template: openvswitch-switch/pki-uri
129 _Description: Open vSwitch PKI server host name or URL:
130 Specify a URL to the Open vSwitch public key infrastructure (PKI). If a
131 host name or IP address is specified in place of a URL, then
132 http://<host>/openvswitch/pki/ will be used,
133 where <host> is the specified host name or IP address.
135 The Open vSwitch PKI is usually on the same machine as the OpenFlow
138 The setup process will connect to the Open vSwitch PKI server over
139 HTTP, using the system's configured default HTTP proxy (if any).
141 Template: openvswitch-switch/fetch-cacert-failed
143 _Description: The switch CA certificate could not be retrieved.
144 Retrieval of ${url} failed, with the following status: "${error}".
146 Ensure that the Open vSwitch PKI server is correctly configured and
147 available at ${pki-uri}. If the system is configured to use an HTTP
148 proxy, also make sure that the HTTP proxy is available and that the
149 PKI server can be reached through it.
151 Template: openvswitch-switch/verify-controller-ca
154 _Description: Is ${fingerprint} the controller CA's fingerprint?
155 If a man-in-the-middle attack is possible in your network
156 environment, check that the controller CA's fingerprint is really
157 ${fingerprint}. Answer "true" if it matches, "false" if
158 there is a discrepancy.
160 If a man-in-the-middle attack is not a concern, there is no need to
161 verify the fingerprint. Simply answer "true".
163 Template: openvswitch-switch/send-cert-req
166 _Description: Send certificate request to switch CA?
167 Before it can connect to the controller over SSL, the Open vSwitch's
168 key must be signed by the switch certificate authority (CA) located
169 on the Open vSwitch PKI server, which is usually collocated with
170 the OpenFlow controller. A signing request can be sent to the PKI
173 Answer "true" to send a signing request to the switch CA now. This is
174 ordinarily the correct choice. There is no harm in sending a given
175 signing request more than once.
177 Answer "false" to skip sending a signing request to the switch CA.
178 Unless the request has already been sent to the switch CA, manual
179 sending of the request and signing will be necessary.
181 Template: openvswitch-switch/send-cert-req-failed
183 _Description: The certificate request could not be sent.
184 Posting to ${url} failed, with the following status: "${error}".
186 Ensure that the Open vSwitch PKI server is correctly configured and
187 available at ${pki-uri}.
189 Template: openvswitch-switch/fetch-switch-cert
191 _Description: Fetch signed switch certificate from PKI server?
192 Before it can connect to the controller over SSL, the Open vSwitch's
193 key must be signed by the switch certificate authority (CA) located
194 on the Open vSwitch PKI server, which is usually collocated with the
197 At this point, a signing request has been sent to the switch CA (or
198 sending a request has been manually skipped), but the signed
199 certificate has not yet been retrieved. Manual action may need to be
200 taken at the PKI server to approve the signing request.
202 Answer "true" to attempt to retrieve the signed switch certificate
203 from the switch CA. If the switch certificate request has been
204 signed at the PKI server, this is the correct choice.
206 Answer "false" to postpone switch configuration. The configuration
207 process must be restarted later, when the switch certificate request
210 Template: openvswitch-switch/fetch-switch-cert-failed
212 _Description: Signed switch certificate could not be retrieved.
213 The signed switch certificate could not be retrieved from the switch
214 CA: retrieval of ${url} failed, with the following status: "${error}".
216 This probably indicates that the switch's certificate request has not
217 yet been signed. If this is the problem, it may be fixed by signing
218 the certificate request at ${pki-uri}, then trying to fetch the
219 signed switch certificate again.
