== Introspection using the VTY

OsmoCBC offers a VTY interface on TCP port 4264. Like all Osmocom VTY interfaces,
it is normally bound only to the loopback address 127.0.0.1.  You can change this
via the configuration.

The actual IP/Port is printed to the log at startup time:

=== Peer State

Using the `show peers` command, you can check on the state of all configured and/or connected
peers:
