@ -27,24 +27,8 @@ Load the batman-adv module into your kernel::
$ insmod batman-adv.ko
The module is now waiting for activation. You must add some interfaces on which
batman can operate. After loading the module batman advanced will scan your
systems interfaces to search for compatible interfaces. Once found, it will
create subfolders in the ``/sys`` directories of each supported interface,
e.g.::
$ ls /sys/class/net/eth0/batman_adv/
elp_interval iface_status mesh_iface throughput_override
If an interface does not have the ``batman_adv`` subfolder, it probably is not
supported. Not supported interfaces are: loopback, non-ethernet and batman's
own interfaces.
Note: After the module was loaded it will continuously watch for new
interfaces to verify the compatibility. There is no need to reload the module
if you plug your USB wifi adapter into your machine after batman advanced was
initially loaded.
The batman-adv soft-interface can be created using the iproute2 tool ``ip``::

Repeat this step for all interfaces you wish to add. Now batman-adv starts
using/broadcasting on this/these interface(s).
By reading the "iface_status" file you can check its status::
$ cat /sys/class/net/eth0/batman_adv/iface_status
active
To deactivate an interface you have to detach it from the "bat0" interface::
$ ip link set dev eth0 nomaster
The same can also be done using the batctl interface subcommand::
All mesh wide settings can be found in batman's own interface folder::
batctl -m bat0 interface create
batctl -m bat0 interface add -M eth0
$ ls /sys/class/net/bat0/mesh/
aggregated_ogms fragmentation isolation_mark routing_algo
ap_isolation gw_bandwidth log_level vlan0
bonding gw_mode multicast_mode
bridge_loop_avoidance gw_sel_class network_coding
distributed_arp_table hop_penalty orig_interval
To detach eth0 and destroy bat0::
There is a special folder for debugging information::
batctl -m bat0 interface del -M eth0
batctl -m bat0 interface destroy
$ ls /sys/kernel/debug/batman_adv/bat0/
bla_backbone_table log neighbors transtable_local
bla_claim_table mcast_flags originators
dat_cache nc socket
gateways nc_nodes transtable_global
There are additional settings for each batadv mesh interface, vlan and hardif
which can be modified using batctl. Detailed information about this can be found
in its manual.
Some of the files contain all sort of status information regarding the mesh
network. For example, you can view the table of originators (mesh
participants) with::
For instance, you can check the current originator interval (value
in milliseconds which determines how often batman-adv sends its broadcast
packets)::
$ cat /sys/kernel/debug/batman_adv/bat0/originators
Other files allow to change batman's behaviour to better fit your requirements.
For instance, you can check the current originator interval (value in
milliseconds which determines how often batman sends its broadcast packets)::
$ cat /sys/class/net/bat0/mesh/orig_interval
$ batctl -M bat0 orig_interval
1000
and also change its value::
$ echo 3000 > /sys/class/net/bat0/mesh/orig_interval
$ batctl -M bat0 orig_interval 3000
In very mobile scenarios, you might want to adjust the originator interval to a
lower value. This will make the mesh more responsive to topology changes, but
will also increase the overhead.
Information about the current state can be accessed via the batadv generic
netlink family. batctl provides human readable version via its debug tables
subcommands.

menuconfig" and enable the option ``B.A.T.M.A.N. debugging``
(``CONFIG_BATMAN_ADV_DEBUG=y``).
Those additional debug messages can be accessed using a special file in
debugfs::
Those additional debug messages can be accessed using the perf infrastructure::
$ cat /sys/kernel/debug/batman_adv/bat0/log
$ trace-cmd stream -e batadv:batadv_dbg
The additional debug output is by default disabled. It can be enabled during
run time. Following log_levels are defined:
run time::
.. flat-table::
$ batctl -m bat0 loglevel routes tt
* - 0
- All debug output disabled
* - 1
- Enable messages related to routing / flooding / broadcasting
* - 2
- Enable messages related to route added / changed / deleted
* - 4
- Enable messages related to translation table operations
* - 8
- Enable messages related to bridge loop avoidance
* - 16
- Enable messages related to DAT, ARP snooping and parsing
* - 32
- Enable messages related to network coding
* - 64
- Enable messages related to multicast
* - 128
- Enable messages related to throughput meter
* - 255
- Enable all messages
The debug output can be changed at runtime using the file
``/sys/class/net/bat0/mesh/log_level``. e.g.::
$ echo 6 > /sys/class/net/bat0/mesh/log_level
will enable debug messages for when routes change.
