-If a \fIbridge\fR argument is given, the settings apply only to the
-specified bridge. Otherwise, they apply to the Open vSwitch instance,
-and its configuration applies to any bridge that has not been explicitly
-configured through a \fIbridge\fR argument.
+For each of these commands, a \fIbridge\fR of \fBdefault\fR applies
+the configuration as the default for any bridge that has not been
+explicitly configured. Otherwise, \fIbridge\fR must name a bridge,
+and the settings apply only to that bridge. (Omitting \fIbridge\fR
+entirely usually has the same effect as specifying \fBdefault\fR.)
