If no parameter is given the current log level settings are displayed otherwise the parameter is used to set the log level. Level 0 disables all verbose logging. Level 1 enables messages related to routing / flooding / broadcasting. Level 2 enables messages related to route or hna added / changed / deleted. Level 3 enables all messages. The messages are sent to the kernel log. Use \fBdmesg\fP(1) to see them. Make sure to have debugging output enabled when compiling the module otherwise the output as well as the loglevel options won't be available.

-batctl will read the file logfile, or stdin if the logfile parameter is not given, applying filtering so only the B.A.T.M.A.N. Advanced messages are displayed. Once the end of the file has been reached batctl will exit unless the option "\-w" was specified which causes batctl to continue reading the file and print log output whenever new log data has been appended to the file.

+batctl will read the batman-adv debug log which has to be compiled into the kernel module. If "\-n" is given batctl will not replace the MAC addresses with bat\-host names in the output.

If no parameter is given the current gateway mode is displayed otherwise the parameter is used to set the gateway mode. The second (optional) argument specifies the gateway class. Its function depends on whether the node is a server or a client. If the node is a server this parameter is used to inform other nodes in the network about this node's internet connection bandwidth. Just enter any number (optionally followed by "kbit" or "mbit") and the batman-adv module will guess your appropriate gateway class. Use "/" to separate the down\(hy and upload rates. You can omit the upload rate and the module will assume an upload of download / 5.
