That is "fdb->dst is null, the dst mac (f8:e7:1e:xx:xx:xx) of the packet is the same as br's mac, something wrong?"

What means it?

And what is fdb?

Thanks.

Hello Jeronimo,

The 'fdb' is the AP's forwarding DB table. When an AP receives a packet, it will try to add the MAC
into the table. It seems a packet might have got corrupted, "fdb->dst is null", but this is a warning msg,
and not impacting the AP function.

Do you see these messages frequently, and/or are there any type of client problems associated?

I am not yet recognize whether it effects client's association or not.

Regards.

Did this ever get solved? I have a ruckus r600 Unleashed that's doing the exact same thing.

In my case, this corrupt packet bubbles up to the DHCP server has a new request, which issues a new IP to the AP. After a while, the AP gets confused (since it is holding onto the old IP, but now has a new IP from the DHCP server).

... and to resolve this weirdness, the AP has to reboot itself thereby losing network.
