Is it possible to configure the 2013 Airport Extreme to use a syslog server? I know it was (and still is) possible to configure the earlier Airport Extreme and Airport Express stations to forward syslog events to an external server.

The trick is to use AirPort Utility 5.6.1

But is it possible to do the same with the current (mid 2013) model? Will AirPort Utility 5.6.1 work with these models?
Well, I bought one and tried.

AirPort Utility 5.6.1 complains about incompatible hardware and missing parameters, but apart from that it works :) It's possible to configure the syslog server.
