Mpd provides to user a command line interface on stdin and
TCP port. Here mpd commands can be entered to
configure the various layers and check
the status of the defined bundles and links.
The commands available at the command line interface
are exactly the same ones available in the
mpd.links config files.
At any given time, there is always an active bundle
and an active link within that bundle. These are
shown in the prompt. Here is an example of running mpd
with a configuration in
mpd.conf that defines
myisp containing two links
By that time, mpd has already read in and executed all the commands associated with the configuration
$ mpd config1 Multi-link PPP daemon for FreeBSD process 26177 started, version 4.2 (firstname.lastname@example.org 15:37 19-Jun-2007) [myisp] ppp node is "mpd771-myisp" [myisp] using interface ng0
config1, which defines the bundle
myisp. When the bundle is created mpd logs a message showing the name of the associated netgraph
ng_ppp(4)node and system interface. In this case
mpd771-myispis the netgraph node and
ng0is the interface.
To control mpd runtime you can connect to mpd's Telnet console.

mpd.conf. Also, if changing the link requires changing bundles as well, mpd will do that too.
The available commands are described in the next chapter.
When mpd is running the
help can be used to
get more information on a specific command:

Mpd allows you to use only a prefix of a command, as long as the command is unambigous:
