LOGICAL SWITCH COMMANDS
ls-add Creates a new, unnamed logical switch, which initially has
no ports. The switch does not have a name, other commands
must refer to this switch by its UUID.
[--may-exist | --add-duplicate] ls-add switch
Creates a new logical switch named switch, which initially
has no ports.
The OVN northbound database schema does not require
logical switch names to be unique, but the whole point to
the names is to provide an easy way for humans to refer to
the switches, making duplicate names unhelpful. Thus,
without any options, this command regards it as an error
if switch is a duplicate name. With --may-exist, adding a
duplicate name succeeds but does not create a new logical
switch. With --add-duplicate, the command really creates a
new logical switch with a duplicate name. It is an error
to specify both options. If there are multiple logical
switches with a duplicate name, configure the logical
switches using the UUID instead of the switch name.
[--if-exists] ls-del switch
Deletes switch. It is an error if switch does not exist,
unless --if-exists is specified.
ls-list
Lists all existing switches on standard output, one per
line.
