NAME
       ovn-ic-sbctl  - Open Virtual Network interconnection southbound db man‐
       agement utility

SYNOPSIS
       ovn-ic-sbctl [options] command [arg...]

DESCRIPTION
       This utility can be used to manage the OVN  interconnection  southbound
       database.

GENERAL COMMANDS
       init   Initializes  the  database,  if it is empty. If the database has
              already been initialized, this command has no effect.

       show [availability_zone]
              Prints a brief overview of the database contents. If  availabil
              ity_zone  is provided, only records related to that availability
              zone are shown.

DATABASE COMMANDS
       These commands query and modify the contents of ovsdb tables. They  are
       a slight abstraction of the ovsdb interface and as such they operate at
       a lower level than other ovn-ic-sbctl commands.

       Identifying Tables, Records, and Columns

       Each of these commands has a table parameter to identify a table within
       the database. Many of them also take a record parameter that identifies
       a particular record within a table. The record  parameter  may  be  the
       UUID  for  a  record, which may be abbreviated to its first 4 (or more)
       hex digits, as long as that is unique.  Many  tables  offer  additional
       ways  to  identify  records.  Some commands also take column parameters
       that identify a particular field within the records in a table.

       For a list of tables and their columns, see ovn-ic-sb(5) or see the ta‐
       ble listing from the --help option.

       Record names must be specified in full and with correct capitalization,
       except that UUIDs may be abbreviated to their first  4  (or  more)  hex
       digits, as long as that is unique within the table. Names of tables and
       columns are not case-sensitive, and - and _  are  treated  interchange‐
       ably.  Unique  abbreviations  of table and column names are acceptable,
       e.g. g or gatew is sufficient to identify the Gateway table.

       Database Values

       Each column in the database accepts a fixed type of data. The currently
       defined basic types, and their representations, are:

              integer
                     A  decimal integer in the range -2**63 to 2**63-1, inclu‐
                     sive.

              real   A floating-point number.

              Boolean
                     True or false, written true or false, respectively.

              string An arbitrary Unicode string, except that null  bytes  are
                     not  allowed.  Quotes  are optional for most strings that
                     begin with an English letter or  underscore  and  consist
                     only  of letters, underscores, hyphens, and periods. How‐
                     ever, true and false and strings that match the syntax of
                     UUIDs  (see  below)  must be enclosed in double quotes to
                     distinguish them from  other  basic  types.  When  double
                     quotes  are  used, the syntax is that of strings in JSON,
                     e.g. backslashes may be used to  escape  special  charac‐
                     ters.  The  empty string must be represented as a pair of
                     double quotes ("").

              UUID   Either a universally unique identifier in  the  style  of
                     RFC  4122,  e.g. f81d4fae-7dec-11d0-a765-00a0c91e6bf6, or
                     an @name defined by a get or create  command  within  the
                     same ovs-vsctl invocation.

       Multiple values in a single column may be separated by spaces or a sin‐
       gle comma.  When  multiple  values  are  present,  duplicates  are  not
       allowed,  and order is not important. Conversely, some database columns
       can have an empty set of values, represented as [], and square brackets
       may optionally enclose other non-empty sets or single values as well.

       A  few  database columns are ``maps’’ of key-value pairs, where the key
       and the value are each some fixed database type. These are specified in
       the  form key=value, where key and value follow the syntax for the col‐
       umn’s key type and value type, respectively. When  multiple  pairs  are
       present  (separated  by  spaces  or  a  comma),  duplicate keys are not
       allowed, and again the order is not  important.  Duplicate  values  are
       allowed. An empty map is represented as {}. Curly braces may optionally
       enclose non-empty maps as well (but use quotes  to  prevent  the  shell
       from  expanding other-config={0=x,1=y} into other-config=0=x other-con
       fig=1=y, which may not have the desired effect).

       Database Command Syntax

              [--if-exists]    [--columns=column[,column]...]    list    table
              [record]...
                     Lists  the  data  in each specified record. If no records
                     are specified, lists all the records in table.

                     If --columns is specified, only the requested columns are
                     listed,  in  the  specified order. Otherwise, all columns
                     are listed, in alphabetical order by column name.

                     Without --if-exists, it is  an  error  if  any  specified
                     record  does  not  exist.  With  --if-exists, the command
                     ignores any record that does not exist, without producing
                     any output.

              [--columns=column[,column]...]       find       table      [col
              umn[:key]=value]...
                     Lists the data in  each  record  in  table  whose  column
                     equals  value  or, if key is specified, whose column con‐
                     tains a key with the specified value. The following oper‐
                     ators  may  be used where = is written in the syntax sum‐
                     mary:

                     = != gt;>gt; = >gt;>gt;=
                            Selects records in which column[:key] equals, does
                            not  equal, is less than, is greater than, is less
                            than or equal to, or is greater than or  equal  to
                            value, respectively.

                            Consider  column[:key]  and  value as sets of ele‐
                            ments. Identical sets are considered equal. Other‐
                            wise,  if  the sets have different numbers of ele‐
                            ments, then the set with more elements is  consid‐
                            ered  to  be larger. Otherwise, consider a element
                            from each set pairwise, in increasing order within
                            each  set.  The first pair that differs determines
                            the result. (For a column that contains  key-value
                            pairs, first all the keys are compared, and values
                            are considered only if the two sets contain  iden‐
                            tical keys.)

                     {=} {!=}
                            Test for set equality or inequality, respectively.

                     {=}   Selects  records in which column[:key] is a subset
                            of value. For example, flood-vlans{=}1,2  selects
                            records  in  which  the  flood-vlans column is the
                            empty set or contains 1 or 2 or both.

                     {}    Selects records in which column[:key] is a  proper
                            subset  of  value.  For example, flood-vlans{}1,2
                            selects records in which the flood-vlans column is
                            the empty set or contains 1 or 2 but not both.

                     {>gt;>gt;=} {>gt;>gt;}
                            Same  as  {=}  and {}, respectively, except that
                            the  relationship  is   reversed.   For   example,
                            flood-vlans{>gt;>gt;=}1,2  selects  records  in which the
                            flood-vlans column contains both 1 and 2.

                     The  following  operators  are  available  only  in  Open
                     vSwitch 2.16 and later:

                     {in}   Selects  records  in  which  every element in col
                            umn[:key] is also in value. (This is the  same  as
                            {=}.)

                     {not-in}
                            Selects  records  in  which  every element in col
                            umn[:key] is not in value.

                     For arithmetic operators (= != gt;>gt; = >gt;>gt;=),  when  key  is
                     specified  but a particular record’s column does not con‐
                     tain key, the record is always omitted from the  results.
                     Thus,   the   condition   other-config:mtu!=1500  matches
                     records that have a mtu key whose value is not 1500,  but
                     not those that lack an mtu key.

                     For  the  set operators, when key is specified but a par‐
                     ticular record’s column does not contain key, the compar‐
                     ison  is  done  against an empty set. Thus, the condition
                     other-config:mtu{!=}1500 matches records that have a  mtu
                     key  whose  value  is not 1500 and those that lack an mtu
                     key.

                     Don’t forget to escape gt;>gt; from interpretation by  the
                     shell.

                     If --columns is specified, only the requested columns are
                     listed, in the specified order. Otherwise all columns are
                     listed, in alphabetical order by column name.

                     The  UUIDs  shown  for rows created in the same ovs-vsctl
                     invocation will be wrong.

              [--if-exists] [--id=@name] get table record [column[:key]]...
                     Prints the value of each specified column  in  the  given
                     record in table. For map columns, a key may optionally be
                     specified, in which case the value associated with key in
                     the column is printed, instead of the entire map.

                     Without  --if-exists,  it  is an error if record does not
                     exist or key is specified,  if  key  does  not  exist  in
                     record. With --if-exists, a missing record yields no out‐
                     put and a missing key prints a blank line.

                     If @name is specified, then the UUID for  record  may  be
                     referred  to  by  that  name  later in the same ovs-vsctl
                     invocation in contexts where a UUID is expected.

                     Both --id and the column arguments are optional, but usu‐
                     ally  at  least  one or the other should be specified. If
                     both are omitted, then get has no effect except to verify
                     that record exists in table.

                     --id and --if-exists cannot be used together.

              [--if-exists] set table record column[:key]=value...
                     Sets  the  value  of  each  specified column in the given
                     record in table to value. For  map  columns,  a  key  may
                     optionally  be specified, in which case the value associ‐
                     ated with key in that column is  changed  (or  added,  if
                     none exists), instead of the entire map.

                     Without  --if-exists,  it  is an error if record does not
                     exist. With --if-exists, this  command  does  nothing  if
                     record does not exist.

              [--if-exists] add table record column [key=]value...
                     Adds  the  specified value or key-value pair to column in
                     record in  table.  If  column  is  a  map,  then  key  is
                     required,  otherwise  it  is  prohibited.  If key already
                     exists in a map column, then the  current  value  is  not
                     replaced  (use  the  set  command  to replace an existing
                     value).

                     Without --if-exists, it is an error if  record  does  not
                     exist.  With  --if-exists,  this  command does nothing if
                     record does not exist.

              [--if-exists] remove table record column value...

                     [--if-exists] remove table record column key...

                     [--if-exists] remove  table  record  column  key=value...
                     Removes the specified values or key-value pairs from col
                     umn in record in table. The first form applies to columns
                     that  are  not maps: each specified value is removed from
                     the column. The second and third forms apply to map  col‐
                     umns: if only a key is specified, then any key-value pair
                     with the given key is removed, regardless of  its  value;
                     if  a  value is given then a pair is removed only if both
                     key and value match.

                     It is not an error if the column  does  not  contain  the
                     specified key or value or pair.

                     Without  --if-exists,  it  is an error if record does not
                     exist. With --if-exists, this  command  does  nothing  if
                     record does not exist.

              [--if-exists] clear table record column...
                     Sets  each  column in record in table to the empty set or
                     empty map, as appropriate. This command applies  only  to
                     columns that are allowed to be empty.

                     Without  --if-exists,  it  is an error if record does not
                     exist. With --if-exists, this  command  does  nothing  if
                     record does not exist.

              [--id=(@name|uuid)] create table column[:key]=value...
                     Creates a new record in table and sets the initial values
                     of each column. Columns not explicitly set  will  receive
                     their default values. Outputs the UUID of the new row.

                     If  @name is specified, then the UUID for the new row may
                     be referred to by that name elsewhere in the  same  \*(PN
                     invocation  in  contexts  where  a UUID is expected. Such
                     references may precede or follow the create command.

                     If a valid uuid is specified, then it is used as the UUID
                     of the new row.

                     Caution (ovs-vsctl as example)
                            Records  in the Open vSwitch database are signifi‐
                            cant only when they can  be  reached  directly  or
                            indirectly from the Open_vSwitch table. Except for
                            records in the QoS or Queue tables,  records  that
                            are  not reachable from the Open_vSwitch table are
                            automatically  deleted  from  the  database.  This
                            deletion  happens immediately, without waiting for
                            additional ovs-vsctl commands  or  other  database
                            activity. Thus, a create command must generally be
                            accompanied by additional commands within the same
                            ovs-vsctl  invocation to add a chain of references
                            to the newly created  record  from  the  top-level
                            Open_vSwitch  record.  The  EXAMPLES section gives
                            some examples that show how to do this.

              [--if-exists] destroy table record...
                     Deletes  each  specified  record   from   table.   Unless
                     --if-exists is specified, each records must exist.

              --all destroy table
                     Deletes all records from the table.

                     Caution (ovs-vsctl as example)
                            The  destroy command is only useful for records in
                            the QoS or Queue tables. Records in  other  tables
                            are  automatically  deleted from the database when
                            they become unreachable from the Open_vSwitch  ta‐
                            ble.  This  means that deleting the last reference
                            to a record is sufficient for deleting the  record
                            itself.  For  records  in these tables, destroy is
                            silently ignored. See the EXAMPLES  section  below
                            for more information.

              wait-until table record [column[:key]=value]...
                     Waits  until  table  contains a record named record whose
                     column equals value or, if key is specified, whose column
                     contains  a  key  with  the specified value. This command
                     supports the same operators and semantics  described  for
                     the find command above.

                     If  no  column[:key]=value arguments are given, this com‐
                     mand waits only until record exists.  If  more  than  one
                     such  argument  is  given, the command waits until all of
                     them are satisfied.

                     Caution (ovs-vsctl as example)
                            Usually wait-until should be placed at the  begin‐
                            ning  of a set of ovs-vsctl commands. For example,
                            wait-until bridge br0  --  get  bridge  br0  data
                            path_id waits until a bridge named br0 is created,
                            then prints its datapath_id  column,  whereas  get
                            bridge  br0  datapath_id  -- wait-until bridge br0
                            will abort if no  bridge  named  br0  exists  when
                            ovs-vsctl initially connects to the database.

                     Consider  specifying --timeout=0 along with --wait-until,
                     to prevent ovs-vsctl from terminating after waiting  only
                     at most 5 seconds.

              comment [arg]...
                     This  command has no effect on behavior, but any database
                     log record created by the command will include  the  com‐
                     mand and its arguments.

REMOTE CONNECTIVITY COMMANDS
       get-connection
              Prints the configured connection(s).

       del-connection
              Deletes the configured connection(s).

       [--inactivity-probe=msecs] set-connection target...
              Sets  the  configured  manager target or targets. Use --inactiv
              ity-probe=msecs to override the default idle connection inactiv‐
              ity probe time. Use 0 to disable inactivity probes.

SSL CONFIGURATION COMMANDS
       get-ssl
              Prints the SSL configuration.

       del-ssl
              Deletes the current SSL configuration.

       [--bootstrap]  set-ssl  private-key  certificate ca-cert [ssl-protocol-
       list [ssl-cipher-list]]
              Sets the SSL configuration.

OPTIONS
       --db database
              The OVSDB database remote to contact. If the OVN_IC_SB_DB  envi‐
              ronment  variable is set, its value is used as the default. Oth‐
              erwise, the default is unix:/ovn_ic_sb_db.sock, but this default
              is  unlikely  to  be  useful  outside of single-machine OVN test
              environments.

       --leader-only
       --no-leader-only
            By default, or with --leader-only, when the database server  is  a
            clustered database, ovn-ic-sbctl will avoid servers other than the
            cluster leader. This ensures that any data that ovn-ic-sbctl reads
            and  reports  is  up-to-date.  With --no-leader-only, ovn-ic-sbctl
            will use any server in the cluster, which means that for read-only
            transactions  it  can  report  and act on stale data (transactions
            that  modify  the  database  are  always  serialized   even   with
            --no-leader-only).  Refer  to Understanding Cluster Consistency in
            ovsdb(7) for more information.

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 speci‐
                   fied 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, the daemon 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 --ver
            bose=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/ovn/program.log.

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

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

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

            ·      unix:file, to use a UNIX domain socket directly. It is pos‐
                   sible 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,  to  use  a 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  exam‐
                   ple,  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, to discard all messages logged to syslog.

            The  default is taken from the OVS_SYSLOG_METHOD environment vari‐
            able; if it is unset, the default is libc.

TABLE FORMATTING OPTIONS
       These options control the format of output from the list and find  com‐
       mands.

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

                   table  2-D text tables with aligned columns.

                   list (default)
                          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 format‐
                   ting 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 col‐
                          umns, items within sets  and  maps  are  space-sepa‐
                          rated, 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 pos‐
                   sible. 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.

   PKI Options
       PKI  configuration  is  required  to  use SSL for the connection to the
       database.

              -p privkey.pem
              --private-key=privkey.pem
                   Specifies a PEM file containing the  private  key  used  as
                   identity for outgoing SSL connections.

              -c cert.pem
              --certificate=cert.pem
                   Specifies  a  PEM file containing a certificate that certi‐
                   fies the private key specified on -p or --private-key to be
                   trustworthy. The certificate must be signed by the certifi‐
                   cate 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 for ver‐
                   ifying certificates presented to this program 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  the  exe‐
                     cutable  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 immedi‐
                     ately drop the connection and reconnect, and from then on
                     all  SSL  connections must be authenticated by a certifi‐
                     cate 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  cer‐
                     tificate.

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

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

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



OVN 22.12.1                      ovn-ic-sbctl                  ovn-ic-sbctl(8)
