If you look at the ruckusconf script here:
https://github.com/bot779/ruckusconf/blob/master/ruckusconfYou'll see a few examples embedded in the "source" of the script itself.
If you're specifically looking for an example of rebooting an individual AP though the controller, here it is:
./ruckusconf --debug --command 'rksap_cli -a 24:c9:a1:29:47:a0 "reboot"' 192.168.3.180
In this example, the IP refers to your controller and the MAC address refers to your AP.
The commandline would be very different if you wanted to use ruckusconf to contact the AP directly. (as opposed to going through the controller)
That (I believe) would be:
./ruckusconf --ap --command "reboot" 192.168.3.99
where the IP refers to the AP and not the controller.
Also, I've got some new code that allows me to schedule commands on the controller without using cron, so I don't have to embed passwords into a cron job.
If there's interest in that, I could post it as well.
