options : bfd-decay-min-rx
optional string
options : bfd-min-tx optional string
options : bfd-mult optional string
options : mac_prefix optional string
options : controller_event optional string, either true or
false

Details:
Status:
These columns allow a client to track the overall configuration
state of the system.
nb_cfg: integer
Sequence number for client to increment. When a client
modifies any part of the northbound database configuration
and wishes to wait for ovn-northd and possibly all of the
hypervisors to finish applying the changes, it may
increment this sequence number.
sb_cfg: integer
Sequence number that ovn-northd sets to the value of
nb_cfg after it finishes applying the corresponding
configuration changes to the OVN_Southbound database.
hv_cfg: integer
Sequence number that ovn-northd sets to the smallest
sequence number of all the chassis in the system, as
reported in the Chassis table in the southbound database.
Thus, hv_cfg equals nb_cfg if all chassis are caught up
with the northbound configuration (which may never happen,
if any chassis is down). This value can regress, if a
chassis was removed from the system and rejoins before
catching up.
Common Columns:
external_ids: map of string-string pairs
See External IDs at the beginning of this document.
Common options:
options: map of string-string pairs
This column provides general key/value settings. The
supported options are described individually below.
Options for configuring BFD:
These options apply when ovn-controller configures BFD on tunnels
interfaces.
options : bfd-min-rx: optional string
BFD option min-rx value to use when configuring BFD on
tunnel interfaces.
options : bfd-decay-min-rx: optional string
BFD option decay-min-rx value to use when configuring BFD
on tunnel interfaces.
options : bfd-min-tx: optional string
BFD option min-tx value to use when configuring BFD on
tunnel interfaces.
options : bfd-mult: optional string
BFD option mult value to use when configuring BFD on
tunnel interfaces.
options : mac_prefix: optional string
Configure a given OUI to be used as prefix when L2 address
is dynamically assigned, e.g. 00:11:22
options : controller_event: optional string, either true or false
Value set by the CMS to enable/disable ovn-controller
event reporting. Traffic into OVS can raise a 'controller'
event that results in a Controller_Event being written to
the Controller_Event table in SBDB. When the CMS has seen
the event and taken appropriate action, it can remove the
correponding row in Controller_Event table. The intention
is for a CMS to see the events and take some sort of
action. Please see the Controller_Event table in SBDB.
Connection Options:
connections: set of Connections
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 Connection table for more information.
ssl: optional SSL
Global SSL configuration.
Security Configurations:
ipsec: boolean
Tunnel encryption configuration. If this column is set to
be true, all OVN tunnels will be encrypted with IPsec.
