.SS "Bridge Configuration"
A bridge (switch) with a given \fIname\fR is configured by specifying
the names of its network devices as values for key

The names given on \fBbridge.\fIname\fB.port\fR must be the names of
existing network devices, except for ``internal ports.'' An internal
port is a simulated network device that receives traffic only
-through the virtual switch and switches any traffic sent it through

The regular expression is implicitly anchored at the beginning of the
controller location string, as if it begins with \fB^\fR.
By default, or if this is set to \fBtrue\fR, \fBovs\-vswitchd\fR connects
to the controller in-band. If this is set to \fBfalse\fR,
\fBovs\-vswitchd\fR connects to the controller out-of-band. Refer to
-\fBsecchan\fR(8) for a description of in-band and out-of-band control.
