[-v ] subcommand
[interface ...] |
rtadvctl
is a utility that communicates with the
rtadvd(8)
daemon and displays information about Router Advertisement messages being sent
on each interface.
This utility provides several options and subcommands. The options
are as follows:
-v
- Increase verbosity level. When specified once, the
rtadvctl
utility shows additional information
about prefixes, RDNSS, and DNSSL options. When given twice, it
additionally shows information about inactive interfaces and some
statistics.
The subcommands are as follows:
- reload [interfaces...]
- Specifies to reload the configuration file. If one or more
interfaces are specified, configuration entries for
the interfaces will be reloaded selectively.
- enable interfaces...
- Specifies to mark the interface as enabled and to tries to reload the
configuration entry. This subcommand is useful for dynamically-added
interfaces.
The
rtadvd(8)
daemon marks an interface as enabled if the interface exists and the
configuration file has a valid entry for it when it is invoked.
- disable interfaces...
- Specifies to mark the interface as disabled.
- shutdown
- Makes the
rtadvd(8)
daemon shut down. Note that the
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.
- show [interfaces...]
- Displays information about the Router Advertisement messages being sent on
each interface.
The rtadvctl
command first appeared in
FreeBSD 9.0.
