mpd.scriptAfter connecting to the telnet port,
mpd presents a command line interface.
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.conf and 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
a bundle myisp containing two links modem1
and modem2:
$ mpd config1
Multi-link PPP for FreeBSD, by Archie L. Cobbs.
Based on iij-ppp, by Toshiharu OHNO.
mpd: pid 1419, version 4.0 (root@fish.alkar.net 15:29 15-Dec-2006)
[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
(mpd will automatically select one if not
explicitly told which one to use). In this case
mpd771-myisp is the netgraph node and ng0
is the interface.
To control mpd runtime you can connect to mpd's Telnet console.

[modem1]
The prompt [modem1]
shows the currently active link (modem1).
Any bundle specific commands issued
at this point will apply to myisp. Similarly,
any link specific commands will apply to modem1.
To change the active link or bundle, use the link
or bundle command:
[modem1] link modem2
[modem2]
myisp or
modem2, as appropriate. This technique works
the same way in 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:
[modem2] help show
