Screwed up your Synology NAS network settings?

Today I made a stupid change to the network settings on my Synology NAS, and it resulted in the IP being inaccessible, and therefore the management interfaces (http/ssl) too. At first there was a short panic that I would have to reset something to get access, which really feels like using a hammer to crack a nut as the old saying goes. Then I thought of a simple back up route that got me in, so I thought I’d note it down to help someone else (or myself next time I do this).

(Side note: I do believe there is a type of reset you can do that just resets the network settings, but I’ve not tried it).

ESXi Autostart Start Delay, Stop Delay & Stop Action

I spent a lot longer than I would have liked today googling for more information on the ESXi Autostart options of Start Delay, Stop Delay and Stop Action. In the end my friend Keith’s Google-Fu was stronger than mine and he pointed me in the right direction. Because the articles we found (listed below) don’t use exactly the same terminology (hence me not finding the answers I wanted) I decided to summarise them here with the “correct” terminology of the latest ESXi 7.0 UI.

Will we be able to capture 802.11ax frames?

This blog post started out as a question to Jim Vajda on Twitter, but I quickly realised there were too many facets to the question for 240 characters. So I thought I’d lay my thoughts out in a blog post instead.

While listening to Jim on the The Wireless Pubcast (ep 16) the topic of capturing frames in an 802.11ax world was brought up. Several distinguished people in the Wi-Fi community have suggested that we won’t be able to capture frames using anything but the associated AP. Jim talked this through with the strange gentlemen from the Pubcast and this is my counter opinion/confusion on the topic.

Convert Aruba Central AP to Campus AP

As I started playing around with Aruba kit I found myself wanting to change the two lab AP’s I had from Instant AP’s, to Central AP’s and then to Campus AP’s. I could find instructions on taking Instant AP’s to Campus AP’s, or Instant AP’s to Central AP’s, but I could not find instructions for taking a Central AP to a Campus AP. Having figured it out I wanted to document it to help others.

TL;DR:
1. Unsubscribe AP(s) from Central
2. Open local web UI on the AP
3. Go to Maintenance > Convert

802.11r Fast Transition not working in your Cisco home lab?

I wanted to test out and analyse Fast Transition in my Cisco home lab but at the first attempt it did not work – the clients were doing full Dot1X authentication each roam. Everything on the SSID/WLAN looked correct, and the clients were connecting/roaming ok, so it wasn’t a certificate or security setting issue.

Thankfully it didn’t take long to figure it out, but I wanted to put this short post together so that hopefully it takes you even less time.

Cisco’s 802.11r/FT settings & Adaptive mode explained

I see questions come up more and more often around Cisco’s Fast Transition settings (aka FT or 802.11r). In particular mixing non-FT and FT clients on the same SSID, and the role of Adaptive mode. I myself totally misunderstood how their FT Adaptive mode worked until two weeks ago.

There is an awesome culture within Vocera of doing as much as we can to provide guidance to our customers, even when that means providing assistance on another vendors equipment. One such opportunity occurred two weeks ago when a customer wanted to use our voice clients with Fast Transition (the IEEE’s feature name for the 802.11r amendment), but had older Cisco phones on the same SSID that do not support FT. We spun up our lab to test it out and these are the findings.
