Indeed a useful post for Ruckus clients, thank you for your contribution.
You could also include some info on how to capture on the uplink of the AP (on eth0). Sometimes, when troubleshooting is useful to compare the traffic coming on the uplink of the AP with what it is actually sent on the air side.
Have you notice any impact of enabling packet capture on the AP stability?
I've seen APs crashing after enabling packet capture (whether if it was done from the ZD webUI or from the AP's CLI). We're trying to understand why.
