Does anyone know where I can find documentation on the MacUpd packets that come from dd-wrt?

I can find NetFlow (rFlow) documentation butnot MacUpd.

Old thread but doesn't seem to be any info on this.

Code:
macupd -h

******************************************************************************
*  macupd v2 | send all known Clients (and WDS) from this machine by UDP     *
******************************************************************************


rssi value of all WLAN Clients and MAC-IP combination
developed by Schlegel Stephan (DD-WRT)
Ctl+C Abort this programm
use this command line: rssiupd <server> <port> <interval>

<server>   : IP Adress of server to recive messages
<port>     : Port
<interval> : delay between udp pakets in sec


Once configured, will execute using the following syntax:

Code:
macupd x.x.x.x 2056 10


Likely used to provide logging facility of all mac addresses that connect to the network.

Packet capture will reveal the record format, if it isn't documented anywhere.

Looking at the source code

https://github.com/mirror/dd-wrt/blob/master/opt/macupd/macupd.c

it creates a file from wl output and sends it over UDP

Not sure if macupd will work on Marvell based routers maybe only Broadcom.
