DESCRIPTION         top

       The ovsdb-client program is a command-line client for interacting
       with a running ovsdb-server process.  Each command connects to
       the specified OVSDB server, which may be an OVSDB active or
       passive connection method, as described in ovsdb(7).  The default
       server is unix:/usr/local/var/run/openvswitch/db.sock and the
       default database is Open_vSwitch.

       ovsdb-client supports the method1,method2,...,methodN syntax
       described in ovsdb(7) for connecting to a cluster.  When this
       syntax is used, ovsdb-client tries the cluster members in random
       order until it finds the cluster leader.  Specify the
       --no-leader-only option to instead accept any server that is
       connected to the cluster.

       For an introduction to OVSDB and its implementation in Open
       vSwitch, see ovsdb(7).

       The following sections describe the commands that ovsdb-client
       supports.

   Server-Level Commands
       Most ovsdb-client commands work with an individual database, but
       these commands apply to an entire database server.

       list-dbs [server]
              Connects to server, retrieves the list of known databases,
              and prints them one per line.  These database names are
              the ones that other commands may use for database.

   Database Schema Commands
       These commands obtain the schema from a database and print it or
       part of it.

       get-schema [server] [database]
              Connects to server, retrieves the schema for database, and
              prints it in JSON format.

       list-tables [server] [database]
              Connects to server, retrieves the schema for database, and
              prints a table listing the name of each table within the
              database.

       list-columns [server] [database] table
              Connects to server, retrieves the schema for database, and
              prints a table listing the name and type of each column.
              If table is specified, only columns in that table are
              listed; otherwise, the tables include columns in all
              tables.

   Database Version Management Commands
       An OVSDB schema has a schema version number, and an OVSDB
       database embeds a particular version of an OVSDB schema.  These
       version numbers take the form x.y.z, e.g. 1.2.3.  The OVSDB
       implementation does not enforce a particular version numbering
       scheme, but schemas managed within the Open vSwitch project use
       the following approach.  Whenever the database schema is changed
       in a non-backward compatible way (e.g. deleting a column or a
       table), x is incremented (and y and z are reset to 0).  When the
       database schema is changed in a backward compatible way (e.g.
       adding a new column), y is incremented (and z is reset to 0).
       When the database schema is changed cosmetically (e.g.
       reindenting its syntax), z is incremented.

       Some OVSDB databases and schemas, especially very old ones, do
       not have a version number.

       Schema version numbers and Open vSwitch version numbers are
       independent.

       These commands work with different versions of OVSDB schemas and
       databases.

       convert [server] schema
              Reads an OVSDB schema in JSON format, as specified in the
              OVSDB specification, from schema, then connects to server
              and requests the server to convert the database whose name
              is specified in schema to the schema also specified in
              schema.

              The conversion is atomic, consistent, isolated, and
              durable.  Following the schema change, the server notifies
              clients that use the set_db_change_aware RPC introduced in
              Open vSwitch 2.9 and cancels their outstanding
              transactions and monitors.  The server disconnects other
              clients, enabling them to notice the change when they
              reconnect.

              This command can do simple ``upgrades'' and ``downgrades''
              on a database's schema.  The data in the database must be
              valid when interpreted under schema, with only one
              exception: data for tables and columns that do not exist
              in schema are ignored.  Columns that exist in schema but
              not in the database are set to their default values.  All
              of schema's constraints apply in full.

              Some uses of this command can cause unrecoverable data
              loss.  For example, converting a database from a schema
              that has a given column or table to one that does not will
              delete all data in that column or table.  Back up critical
              databases before converting them.

              This command works with clustered and standalone
              databases.  Standalone databases may also be converted
              (offline) with ovsdb-tool's convert command.

       needs-conversion [server] schema
              Reads the schema from schema, then connects to server and
              requests the schema from the database whose name is
              specified in schema.  If the two schemas are the same,
              prints no on stdout; if they differ, prints yes.

       get-schema-version [server] [database]
              Connects to server, retrieves the schema for database, and
              prints its version number on stdout.  If database was
              created before schema versioning was introduced, then it
              will not have a version number and this command will print
              a blank line.

       get-schema-cksum [server] [database]
              Connects to server, retrieves the schema for database, and
              prints its checksum on stdout.  If database does not
              include a checksum, prints a blank line.

   Data Management Commands
       These commands read or modify the data in a database.

       transact [server] transaction
              Connects to server, sends it the specified transaction,
              which must be a JSON array appropriate for use as the
              params to a JSON-RPC transact request, and prints the
              received reply on stdout.

       query [server] transaction
              This commands acts like a read-only version of transact.
              It connects to server, sends it the specified transaction,
              which must be a JSON array appropriate for use as the
              params to a JSON-RPC transact request, and prints the
              received reply on stdout.  To ensure that the transaction
              does not modify the database, this command appends an
              abort operation to the set of operations included in
              transaction before sending it to the database, and then
              removes the abort result from the reply (if it is
              present).

       dump [server] [database] [table [column...]]
              Connects to server, retrieves all of the data in database,
              and prints it on stdout as a series of tables. If table is
              specified, only that table is retrieved.  If at least one
              column is specified, only those columns are retrieved.

       backup [server] [database] > snapshot
              Connects to server, retrieves a snapshot of the schema and
              data in database, and prints it on stdout in the format
              used for OVSDB standalone and active-backup databases.
              This is an appropriate way to back up any remote database.
              The database snapshot that it outputs is suitable to be
              served up directly by ovsdb-server or used as the input to
              ovsdb-client restore.

              Another way to back up a standalone or active-backup
              database is to copy its database file, e.g. with cp.  This
              is safe even if the database is in use.

              The output does not include ephemeral columns, which by
              design do not survive across restarts of ovsdb-server.

       [--force] restore [server] [database] < snapshot
              Reads snapshot, which must be a OVSDB standalone or
              active-backup database (possibly but not necessarily
              created by ovsdb-client backup).  Then, connects to
              server, verifies that database and snapshot have the same
              schema, then deletes all of the data in database and
              replaces it by snapshot.  The replacement happens
              atomically, in a single transaction.

              UUIDs for rows in the restored database will differ from
              those in snapshot, because the OVSDB protocol does not
              allow clients to specify row UUIDs.  Another way to
              restore a standalone or active-backup database, which does
              also restore row UUIDs, is to stop the server or servers,
              replace the database file by the snapshot, then restart
              the database.  Either way, ephemeral columns are not
              restored, since by design they do not survive across
              restarts of ovsdb-server.

              Normally restore exits with a failure if snapshot and the
              server's database have different schemas.  In such a case,
              it is a good idea to convert the database to the new
              schema before restoring, e.g. with ovsdb-client convert.
              Use --force to proceed regardless of schema differences
              even though the restore might fail with an error or
              succeed with surprising results.

       monitor [server] [database] table [column[,column]...]...
       monitor-cond [server] [database] conditions table
       [column[,column]...]...
       monitor-cond-since [server] [database] [last-id] conditions table
       [column[,column]...]...
              Connects to server and monitors the contents of rows that
              match conditions in table in database. By default, the
              initial contents of table are printed, followed by each
              change as it occurs.  If conditions empty, all rows will
              be monitored. If at least one column is specified, only
              those columns are monitored.  The following column names
              have special meanings:

              !initial
                     Do not print the initial contents of the specified
                     columns.

              !insert
                     Do not print newly inserted rows.

              !delete
                     Do not print deleted rows.

              !modify
                     Do not print modifications to existing rows.

              Multiple [column[,column]...] groups may be specified as
              separate arguments, e.g. to apply different reporting
              parameters to each group.  Whether multiple groups or only
              a single group is specified, any given column may only be
              mentioned once on the command line.

              conditions is a JSON array of <condition> as defined in
              RFC 7047 5.1 with the following change: A condition can be
              either a 3-element JSON array as described in the RFC or a
              boolean value.

              If --detach is used with monitor, monitor-cond or
              monitor-cond-since, then ovsdb-client detaches after it
              has successfully received and printed the initial contents
              of table.

              The monitor command uses RFC 7047 "monitor" method to open
              a monitor session with the server. The monitor-cond and
              monitor-cond-since commandls uses RFC 7047 extension
              "monitor_cond" and "monitor_cond_since" methods. See
              ovsdb-server(1) for details.

       monitor [server] [database] ALL
              Connects to server and monitors the contents of all tables
              in database.  Prints initial values and all kinds of
              changes to all columns in the database.  The --detach
              option causes ovsdb-client to detach after it successfully
              receives and prints the initial database contents.

              The monitor command uses RFC 7047 "monitor" method to open
              a monitor session with the server.

       wait [server] database state
              Waits for database on server to enter a desired state,
              which may be one of:

              added  Waits until a database with the given name has been
                     added to server.

              connected
                     Waits until a database with the given name has been
                     added to server.  Then, if database is clustered,
                     additionally waits until it has joined and
                     connected to its cluster.

              removed
                     Waits until database has been removed from the
                     database server.  This can also be used to wait for
                     a database to complete leaving its cluster, because
                     ovsdb-server removes a database at that point.

              database is mandatory for this command because it is often
              used to check for databases that have not yet been added
              to the server, so that the ovsdb-client semantics of
              acting on a default database do not work.

              This command acts on a particular database server, not on
              a cluster, so server must name a single server, not a
              comma-delimited list of servers.

   Testing commands
       These commands are mostly of interest for testing the correctness
       of the OVSDB server.

       lock [server] lock
       steal [server] lock
       unlock [server] lock
              Connects to server and issues corresponding RFC 7047 lock
              operations on lock. Prints json reply or subsequent update
              messages.  The --detach option causes ovsdb-client to
              detach after it successfully receives and prints the
              initial reply.

              When running with the --detach option, lock, steal, unlock
              and exit commands can be issued by using ovs-appctl. exit
              command causes the ovsdb-client to close its ovsdb-server
              connection before exit.  The lock, steal and unlock
              commands can be used to issue additional lock operations
              over the same ovsdb-server connection. All above commands
              take a single lock argument, which does not have to be the
              same as the lock that ovsdb-client started with.

   Output Formatting Options
       Much of the output from ovsdb-client is in the form of tables.
       The following options controlling output formatting:

       -f format
       --format=format
              Sets the type of table formatting.  The following types of
              format are available:

              table (default)
                     2-D text tables with aligned columns.

              list   A list with one column per line and rows separated
                     by a blank line.

              html   HTML tables.

              csv    Comma-separated values as defined in RFC 4180.

              json   JSON format as defined in RFC 4627.  The output is
                     a sequence of JSON objects, each of which
                     corresponds to one table.  Each JSON object has the
                     following members with the noted values:

                     caption
                            The table's caption.  This member is omitted
                            if the table has no caption.

                     headings
                            An array with one element per table column.
                            Each array element is a string giving the
                            corresponding column's heading.

                     data   An array with one element per table row.
                            Each element is also an array with one
                            element per table column.  The elements of
                            this second-level array are the cells that
                            constitute the table.  Cells that represent
                            OVSDB data or data types are expressed in
                            the format described in the OVSDB
                            specification; other cells are simply
                            expressed as text strings.

       -d format
       --data=format
              Sets the formatting for cells within output tables unless
              the table format is set to json, in which case json
              formatting is always used when formatting cells.  The
              following types of format are available:

              string (default)
                     The simple format described in the Database Values
                     section of ovs-vsctl(8).

              bare   The simple format with punctuation stripped off: []
                     and {} are omitted around sets, maps, and empty
                     columns, items within sets and maps are space-
                     separated, and strings are never quoted.  This
                     format may be easier for scripts to parse.

              json   The RFC 4627 JSON format as described above.

       --no-headings
              This option suppresses the heading row that otherwise
              appears in the first row of table output.

       --pretty
              By default, JSON in output is printed as compactly as
              possible.  This option causes JSON in output to be printed
              in a more readable fashion.  Members of objects and
              elements of arrays are printed one per line, with
              indentation.

              This option does not affect JSON in tables, which is
              always printed compactly.

       --bare Equivalent to --format=list --data=bare --no-headings.

       --max-column-width=n
              For table output only, limits the width of any column in
              the output to n columns.  Longer cell data is truncated to
              fit, as necessary.  Columns are always wide enough to
              display the column names, if the heading row is printed.

       --timestamp
              For the monitor, monitor-cond and monitor-cond-since
              commands, add a timestamp to each table update.  Most
              output formats add the timestamp on a line of its own just
              above the table.  The JSON output format puts the
              timestamp in a member of the top-level JSON object named
              time.

       -t
       --timeout=secs
              Limits ovsdb-client runtime to approximately secs seconds.
              If the timeout expires, ovsdb-client will exit with a
              SIGALRM signal.

   Daemon Options
       The daemon options apply only to the monitor, monitor-cond and
       monitor-cond-since commands.  With any other command, they have
       no effect.

       The following options are valid on POSIX based platforms.

       --pidfile[=pidfile]
              Causes a file (by default, ovsdb-client.pid) to be created
              indicating the PID of the running process.  If the pidfile
              argument is not specified, or if it does not begin with /,
              then it is created in /usr/local/var/run/openvswitch.

              If --pidfile is not specified, no pidfile is created.

       --overwrite-pidfile
              By default, when --pidfile is specified and the specified
              pidfile already exists and is locked by a running process,
              ovsdb-client refuses to start.  Specify
              --overwrite-pidfile to cause it to instead overwrite the
              pidfile.

              When --pidfile is not specified, this option has no
              effect.

       --detach
              Runs ovsdb-client as a background process.  The process
              forks, and in the child it starts a new session, closes
              the standard file descriptors (which has the side effect
              of disabling logging to the console), and changes its
              current directory to the root (unless --no-chdir is
              specified).  After the child completes its initialization,
              the parent exits.

       --monitor
              Creates an additional process to monitor the ovsdb-client
              daemon.  If the daemon dies due to a signal that indicates
              a programming error (SIGABRT, SIGALRM, SIGBUS, SIGFPE,
              SIGILL, SIGPIPE, SIGSEGV, SIGXCPU, or SIGXFSZ) then the
              monitor process starts a new copy of it.  If the daemon
              dies or exits for another reason, the monitor process
              exits.

              This option is normally used with --detach, but it also
              functions without it.

       --no-chdir
              By default, when --detach is specified, ovsdb-client
              changes its current working directory to the root
              directory after it detaches.  Otherwise, invoking
              ovsdb-client from a carelessly chosen directory would
              prevent the administrator from unmounting the file system
              that holds that directory.

              Specifying --no-chdir suppresses this behavior, preventing
              ovsdb-client from changing its current working directory.
              This may be useful for collecting core files, since it is
              common behavior to write core dumps into the current
              working directory and the root directory is not a good
              directory to use.

              This option has no effect when --detach is not specified.

       --no-self-confinement
              By default daemon will try to self-confine itself to work
              with files under well-known directories determined during
              build.  It is better to stick with this default behavior
              and not to use this flag unless some other Access Control
              is used to confine daemon.  Note that in contrast to other
              access control implementations that are typically enforced
              from kernel-space (e.g. DAC or MAC), self-confinement is
              imposed from the user-space daemon itself and hence should
              not be considered as a full confinement strategy, but
              instead should be viewed as an additional layer of
              security.

       --user Causes ovsdb-client to run as a different user specified
              in "user:group", thus dropping most of the root
              privileges. Short forms "user" and ":group" are also
              allowed, with current user or group are assumed
              respectively. Only daemons started by the root user
              accepts this argument.

              On Linux, daemons will be granted CAP_IPC_LOCK and
              CAP_NET_BIND_SERVICES before dropping root privileges.
              Daemons that interact with a datapath, such as
              ovs-vswitchd, will be granted three additional
              capabilities, namely CAP_NET_ADMIN, CAP_NET_BROADCAST and
              CAP_NET_RAW.  The capability change will apply even if the
              new user is root.

              On Windows, this option is not currently supported. For
              security reasons, specifying this option will cause the
              daemon process not to start.

   Logging Options
       -v[spec]
       --verbose=[spec]
              Sets logging levels.  Without any spec, sets the log level
              for every module and destination to dbg.  Otherwise, spec
              is a list of words separated by spaces or commas or
              colons, up to one from each category below:

              •      A valid module name, as displayed by the vlog/list
                     command on ovs-appctl(8), limits the log level
                     change to the specified module.

              •      syslog, console, or file, to limit the log level
                     change to only to the system log, to the console,
                     or to a file, respectively.  (If --detach is
                     specified, ovsdb-client closes its standard file
                     descriptors, so logging to the console will have no
                     effect.)

                     On Windows platform, syslog is accepted as a word
                     and is only useful along with the --syslog-target
                     option (the word has no effect otherwise).

              •      off, emer, err, warn, info, or dbg, to control the
                     log level.  Messages of the given severity or
                     higher will be logged, and messages of lower
                     severity will be filtered out.  off filters out all
                     messages.  See ovs-appctl(8) for a definition of
                     each log level.

              Case is not significant within spec.

              Regardless of the log levels set for file, logging to a
              file will not take place unless --log-file is also
              specified (see below).

              For compatibility with older versions of OVS, any is
              accepted as a word but has no effect.

       -v
       --verbose
              Sets the maximum logging verbosity level, equivalent to
              --verbose=dbg.

       -vPATTERN:destination:pattern
       --verbose=PATTERN:destination:pattern
              Sets the log pattern for destination to pattern.  Refer to
              ovs-appctl(8) for a description of the valid syntax for
              pattern.

       -vFACILITY:facility
       --verbose=FACILITY:facility
              Sets the RFC5424 facility of the log message. facility can
              be one of kern, user, mail, daemon, auth, syslog, lpr,
              news, uucp, clock, ftp, ntp, audit, alert, clock2, local0,
              local1, local2, local3, local4, local5, local6 or local7.
              If this option is not specified, daemon is used as the
              default for the local system syslog and local0 is used
              while sending a message to the target provided via the
              --syslog-target option.

       --log-file[=file]
              Enables logging to a file.  If file is specified, then it
              is used as the exact name for the log file.  The default
              log file name used if file is omitted is
              /usr/local/var/log/openvswitch/ovsdb-client.log.

       --syslog-target=host:port
              Send syslog messages to UDP port on host, in addition to
              the system syslog.  The host must be a numerical IP
              address, not a hostname.

       --syslog-method=method
              Specify method how syslog messages should be sent to
              syslog daemon.  Following forms are supported:

              •      libc, use libc syslog() function.  Downside of
                     using this options is that libc adds fixed prefix
                     to every message before it is actually sent to the
                     syslog daemon over /dev/log UNIX domain socket.

              •      unix:file, use UNIX domain socket directly.  It is
                     possible to specify arbitrary message format with
                     this option.  However, rsyslogd 8.9 and older
                     versions use hard coded parser function anyway that
                     limits UNIX domain socket use.  If you want to use
                     arbitrary message format with older rsyslogd
                     versions, then use UDP socket to localhost IP
                     address instead.

              •      udp:ip:port, use UDP socket.  With this method it
                     is possible to use arbitrary message format also
                     with older rsyslogd.  When sending syslog messages
                     over UDP socket extra precaution needs to be taken
                     into account, for example, syslog daemon needs to
                     be configured to listen on the specified UDP port,
                     accidental iptables rules could be interfering with
                     local syslog traffic and there are some security
                     considerations that apply to UDP sockets, but do
                     not apply to UNIX domain sockets.

              •      null, discards all messages logged to syslog.

              The default is taken from the OVS_SYSLOG_METHOD
              environment variable; if it is unset, the default is libc.

   Public Key Infrastructure Options
       -p privkey.pem
       --private-key=privkey.pem
              Specifies a PEM file containing the private key used as
              ovsdb-client's identity for outgoing SSL connections.

       -c cert.pem
       --certificate=cert.pem
              Specifies a PEM file containing a certificate that
              certifies the private key specified on -p or --private-key
              to be trustworthy.  The certificate must be signed by the
              certificate authority (CA) that the peer in SSL
              connections will use to verify it.

       -C cacert.pem
       --ca-cert=cacert.pem
              Specifies a PEM file containing the CA certificate that
              ovsdb-client should use to verify certificates presented
              to it by SSL peers.  (This may be the same certificate
              that SSL peers use to verify the certificate specified on
              -c or --certificate, or it may be a different one,
              depending on the PKI design in use.)

       -C none
       --ca-cert=none
              Disables verification of certificates presented by SSL
              peers.  This introduces a security risk, because it means
              that certificates cannot be verified to be those of known
              trusted hosts.

       --bootstrap-ca-cert=cacert.pem
              When cacert.pem exists, this option has the same effect as
              -C or --ca-cert.  If it does not exist, then ovsdb-client
              will attempt to obtain the CA certificate from the SSL
              peer on its first SSL connection and save it to the named
              PEM file.  If it is successful, it will immediately drop
              the connection and reconnect, and from then on all SSL
              connections must be authenticated by a certificate signed
              by the CA certificate thus obtained.

              This option exposes the SSL connection to a man-in-the-
              middle attack obtaining the initial CA certificate, but it
              may be useful for bootstrapping.

              This option is only useful if the SSL peer sends its CA
              certificate as part of the SSL certificate chain.  The SSL
              protocol does not require the server to send the CA
              certificate.

              This option is mutually exclusive with -C and --ca-cert.

   SSL Connection Options
       --ssl-protocols=protocols
              Specifies, in a comma- or space-delimited list, the SSL
              protocols ovsdb-client will enable for SSL connections.
              Supported protocols include TLSv1, TLSv1.1, and TLSv1.2.
              Regardless of order, the highest protocol supported by
              both sides will be chosen when making the connection.  The
              default when this option is omitted is
              TLSv1,TLSv1.1,TLSv1.2.

       --ssl-ciphers=ciphers
              Specifies, in OpenSSL cipher string format, the ciphers
              ovsdb-client will support for SSL connections.  The
              default when this option is omitted is HIGH:!aNULL:!MD5.

   Other Options
       --record[=directory]
              Sets the process in "recording" mode, in which it will
              record all the connections, data from streams (Unix domain
              and network sockets) and some other important necessary
              bits, so they could be replayed later.  Recorded data is
              stored in replay files in specified directory.  If
              directory does not begin with /, it is interpreted as
              relative to /usr/local/var/run/openvswitch.  If directory
              is not specified, /usr/local/var/run/openvswitch will be
              used.

       --replay[=directory]
              Sets the process in "replay" mode, in which it will read
              information about connections, data from streams (Unix
              domain and network sockets) and some other necessary bits
              directly from replay files instead of using real sockets.
              Replay files from the directory will be used.  If
              directory does not begin with /, it is interpreted as
              relative to /usr/local/var/run/openvswitch.  If directory
              is not specified, /usr/local/var/run/openvswitch will be
              used.

       -h
       --help Prints a brief help message to the console.

       -V
       --version
              Prints version information to the console.
