I’ve got a tricky one which I’m trying to diagnose, but so far have had no luck.I’ve ended up with a couple spare 9120AXI AP’s from a completed temporary project and decided on setting them up at my home to replace the Wi-Fi portion of my ISP supplie...

I'm wondering if someone can explain the Flex NAT/PAT feature within the Embedded Wireless Controller? I'm familiar with the local switching which is done by default, but am struggling to find some information about how Flex NAT/PAT works.

I've made an interesting observation recently.When devices roam to a 2802i AP they make it there via 802.11r (FT: Fast Transition) no problems, however when they roam back to a 3702i AP they go via 802.11i (Slow).I'm not too fussed as the speed diffe...

I'm been working through troubleshooting this issue for the past two weeks and have checked and changed every setting I can think of within the controller without any luck. I have a single 2802 running the current 8.10.130 Mobility Express image acti...

We had IGMP snooping enabled and it made no difference for us. It could be as simple as an incompatibility between our switching infrastructure but we did not have the time to invest further into it.

TAC couldn’t resolve my issue and we were going in circles. I ended up selling the 9800 setup for a profit to a local MSP, moved to Aruba and have not had issues since.

FT is 802.11r BSS Fast Transition.

Indeed. I think Cisco's got the mDNS Gateway services working perfectly, in fact I have used these in a business setting with great success in the past.mDNS bridging seems to be an entirely different ballgame, and likely only useful for small branche...

I did try running 17.5.1 on my 9120’s but was still experiencing HomeKit no response issues.I’ll PM you the ticket number. The engineer didn’t really know anything about HomeKit so it’s focussed on the mDNS aspect which appears to be the cause.
