.Sh NAME
.Nm rtadvctl
.Nd control program for
.Xr rtadvd 8
daemon
.Sh SYNOPSIS
.Nm
.Op Fl v
.Ar subcommand
.Op Ar interface ...
.Sh DESCRIPTION
.Nm
is a utility that communicates with
.Xr rtadvd 8
daemon and displays information about Router Advertisement messages being
sent on each interface.
.Pp
This utility provides several options and subcommands.
The options are as follows:
.Bl -tag -width indent
.\"
.It Fl v
Increase verbosity level.
When specified once, the
.Nm
utility shows additional information about prefixes, RDNSS, and DNSSL
options.
When given twice, it additionally shows information about
inactive interfaces and some statistics.
.El
.Pp
The subcommands are as follows:
.Bl -tag -width indent
.\"
.It reload Op interfaces...
Specifies to reload the configuration file. If one or more
.Ar interface
is specified, configuration entries for the interfaces will be reloaded
selectively.
.It enable interfaces...
Specifies to mark the interface as enable and to try to reload the
configuration entry.
This subcommand is useful for dynamically-added interfaces.
.Pp
The
.Xr rtadvd 8
daemon marks an interface as enable if the interface exists and the
configuration file has a valid entry for that when it is invoked.
.It disable interfaces...
Specifies to mark the interface as disable.
.It shutdown
Makes the
.Xr rtadvd 8
daemon shut down.
Note that the
.Xr rtadvd 8
daemon will send several RAs with zero lifetime to invalidate the old
information on each interface.
It will take at most nine seconds.
.It show Op interfaces...
Displays information on Router Advertisement messages being sent
on each interface.
.El
.Sh SEE ALSO
.Xr rtadvd 8 ,
.Xr rtadvd.conf 5
.Sh HISTORY
The
.Nm
command first appeared in
.Fx 9.0 .
