+ This database is for local configuration of an ovsdb-server. The + database is meant to be unique, even among multiple clustered db + servers, so that configuration that is local to that server can + be configured separately (e.g. Connection information). +

+ + +

+ The root local configuration table for an ovsdb-server. This table + must have exactly one row. +

+ + + Database clients to which the Open vSwitch database server should + connect or on which it should listen, along with options for how these + connections should be configured. See the + table for more information. + + +

+ Configuration for a database connection to an Open vSwitch database + (OVSDB) client. +

+ +

+ This table primarily configures the Open vSwitch database server + (ovsdb-server). +

+ +

+ The Open vSwitch database server can initiate and maintain active + connections to remote clients. It can also listen for database + connections. +

+ + + +

Connection methods for clients.

+

+ The following connection methods are currently supported: +

+
+
+ ssl:host[:port] +
+
+

+ The specified SSL port on the host at the given + host, which can either be a DNS name (if built with + unbound library) or an IP address. A valid SSL configuration must + be provided when this form is used, this configuration can be + specified via command-line options or the + table. +

+

+ If port is not specified, it defaults to 6640. +

+

+ SSL support is an optional feature that is not always + built as part of Open vSwitch. +

+
+ +
+ tcp:host[:port] +
+
+

+ The specified TCP port on the host at the given + host, which can either be a DNS name (if built with + unbound library) or an IP address. If host is an IPv6 + address, wrap it in square brackets, e.g. + tcp:[::1]:6640. +

+

+ If port is not specified, it defaults to 6640. +

+
+
+ pssl:[port][:host] +
+
+

+ Listens for SSL connections on the specified TCP port. + Specify 0 for port to have the kernel automatically + choose an available port. If host, which can either + be a DNS name (if built with unbound library) or an IP address, + is specified, then connections are restricted to the resolved or + specified local IPaddress (either IPv4 or IPv6 address). If + host is an IPv6 address, wrap in square brackets, + e.g. pssl:6640:[::1]. If host is not + specified then it listens only on IPv4 (but not IPv6) addresses. + A valid SSL configuration must be provided when this form is + used, this can be specified either via command-line options or + the table. +

+

+ If port is not specified, it defaults to 6640. +

+

+ SSL support is an optional feature that is not always built as + part of Open vSwitch. +

+
+
+ ptcp:[port][:host] +
+
+

+ Listens for connections on the specified TCP port. + Specify 0 for port to have the kernel automatically + choose an available port. If host, which can either + be a DNS name (if built with unbound library) or an IP address, + is specified, then connections are restricted to the resolved or + specified local IP address (either IPv4 or IPv6 address). If + host is an IPv6 address, wrap it in square brackets, + e.g. ptcp:6640:[::1]. If host is not + specified then it listens only on IPv4 addresses. +

+

+ If port is not specified, it defaults to 6640. +

+
+
+

When multiple clients are configured, the + values must be unique. Duplicate values yield + unspecified results.

+ + + + true to restrict these connections to read-only + transactions, false to allow them to modify the database. + + + + String containing role name for this connection entry. + + + + + + Maximum number of milliseconds to wait between connection attempts. + Default is implementation-specific. + + + + Maximum number of milliseconds of idle time on connection to the client + before sending an inactivity probe message. If Open vSwitch does not + communicate with the client for the specified number of seconds, it + will send a probe. If a response is not received for the same + additional amount of time, Open vSwitch assumes the connection has been + broken and attempts to reconnect. Default is implementation-specific. + A value of 0 disables inactivity probes. + + + + +

+ Key-value pair of is always updated. + Other key-value pairs in the status columns may be updated depends + on the type. +

+ +

+ When specifies a connection method that + listens for inbound connections (e.g. ptcp: or + punix:), both and + may also be updated while the + remaining key-value pairs are omitted. +

+ +

+ On the other hand, when specifies an + outbound connection, all key-value pairs may be updated, except + the above-mentioned two key-value pairs associated with inbound + connection targets. They are omitted. +

+ + + true if currently connected to this client, + false otherwise. + + + + A human-readable description of the last error on the connection + to the manager; i.e. strerror(errno). This key + will exist only if an error has occurred. + + + +

+ The state of the connection to the manager: +

+
+
VOID
+
Connection is disabled.
+ +
BACKOFF
+
Attempting to reconnect at an increasing period.
+ +
CONNECTING
+
Attempting to connect.
+ +
ACTIVE
+
Connected, remote host responsive.
+ +
IDLE
+
Connection is idle. Waiting for response to keep-alive.
+
+

+ These values may change in the future. They are provided only for + human consumption. +

+ + + + The amount of time since this client last successfully connected + to the database (in seconds). Value is empty if client has never + successfully been connected. + + + + The amount of time since this client last disconnected from the + database (in seconds). Value is empty if client has never + disconnected. + + + + Space-separated list of the names of OVSDB locks that the connection + holds. Omitted if the connection does not hold any locks. + + + + Space-separated list of the names of OVSDB locks that the connection is + currently waiting to acquire. Omitted if the connection is not waiting + for any locks. + + + + Space-separated list of the names of OVSDB locks that the connection + has had stolen by another OVSDB client. Omitted if no locks have been + stolen from this connection. + + + + When specifies a connection method that + listens for inbound connections (e.g. ptcp: or + pssl:) and more than one connection is actually active, + the value is the number of active connections. Otherwise, this + key-value pair is omitted. + + + + When is ptcp: or + pssl:, this is the TCP port on which the OVSDB server is + listening. (This is particularly useful when specifies a port of 0, allowing the kernel to + choose any available port.) + + + + + + The Differentiated Service Code Point (DSCP) is specified using 6 bits + in the Type of Service (TOS) field in the IP header. DSCP provides a + mechanism to classify the network traffic and provide Quality of + Service (QoS) on IP networks. + + The DSCP value specified here is used when establishing the connection + between the manager and the Open vSwitch. If no value is specified, a + default value of 48 is chosen.
