As mentioned in the ovs-appctl man page, you have to look at the man page for
the daemon:
Open vSwitch daemons accept certain commands at runtime to control
their behavior and query their settings. Every daemon accepts a common
set of commands documented under COMMON COMMANDS below. Some daemons
support additional commands documented in their own manpages.
ovs-vswitchd in particular accepts a number of additional commands doc‐
umented in ovs-vswitchd(8).
Here's the relevant section from the ovs-vswitchd man page:
dpif/show
Prints a summary of configured datapaths, including statistics
and a list of connected ports. The port information includes
the OpenFlow port number, datapath port number, and the type.
(The local port is identified as OpenFlow port 65534.)
