In the support case that I had escalated where they called me back and said it would no longer be supported. It is not in the support doc that it is supported because it is NOT supported. Also, it is not in the support doc that the windows client is supported because it also is not supported. I did ask if either would be supported in the future and the windows client was yes, and snmp was no. I did not get an answer as to if they would be eliminating the snmp function from all of the previously released airports and did not get an answer either way. The only hard answers were they were not supporting snmp on the new AE or AE with disk and windows clients were coming in future. The setup was confirmed to be able to be done with the ipad / iphone and restore of your baseconfig could only be supported on a mac OSX.
I have confirmed that the new AE / AE timecapusle does not have snmp ports available nor does the application show it available. I put the old 5th gen AE back in and I do see the snmp function available and can poll it for it's services so I took the new AE back in under the 14 days no questions asked return policy.
I am sad to see this service go since I did (for unknown circumstances) did have a 'blip' on my support at home radar where netflix did slow and buffer a couple of times with the wife and kids watch a movie while I was vpn into work and I could not 'see' what could have been affecting the apple tv and it's download. I didn't record any bandwidth on the downstream netgear switch and speedtest suggested all was well on my ipad (wireless) and desktop, so this anomaly that I am accountable for since I work from home makes me uncomfortable since this new AE became 'un supportable' with it being a proverbial and ironic 'black box' that I technically could not troubleshoot. I monitor dns response times, ect so with wireless speeds being invisible, I am not happy with >75% if my household clients being wireless and non monitorable.
Oh well. Ubiquity and others are up for grabs.
I don't believe this service can be administered with the (currently latest 6.3) version of the AirPort Utility. At least I also couldn't find it in either the utility itself or within its help information.
In addition, Apple Support's Specifications site does not list SNMP for the 802.11ac models as it did for the prior 802.11n ones. Both of these items would tend to make me believe that this service is no longer supported.
