For you other 3 bugs any related to airgroup? I’m having airgroup issue with 8.5.x. Running in centralized mode with no airgroup profiles. Working with TAC they found that the Airgroup config has to be done from /md level and can’t override at lower folder levels. We got past this but now face issue with clients not being marked as airgroup users. If you do show datapath for a user filtering on 5353 the Flags for this will 0o if your hitting the bug. Mine has been recreated in tac lab and now in development hands.

We have Aruba engineers on site. They’ve experienced the issue many times since they have been here. So I am confident that something will be done about this specific bug. We have about 3 more bugs of varying criticality they are looking at.

On the specific bug that Ryan is talking about, I was speaking today with a local partner who was experiencing the bug as well (and I believe has contacted Ryan offline), and their workaround was to change the SSIDs to bridge mode. We already made that change for unrelated reasons* during our final week ofPoC testing which probably explains why we didn't see it recently. I will say that Aruba support seems to be very quick to point fingers at the rest of your infrastructure (DNS, DHCP, RADIUSetc) and so you have to prove it's working, even though it's not been an issue up until the point of the bug. I can understand this attitude but granting a little bit of trust that we have our environment configured correctly since it was working fine with another vendor would be nice. *Airgroup wasn't controllingAirtames correctly, I have a TAC session to gather traces scheduled for tomorrow -- James Andrewartha Network & Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph.

We chose this platform after a nearly 6 monthPoC, because we were hitting a high-impact but low occurrence and unreproducible bug with our Surface Book 2 fleet when connected to our Extreme Wireless network. Microsoft was unable to fix this bug (and it definitely was a client bug, their debug traces showed the Surfaces dropping BAR packets from the AP), so instead I hope they can fix the new bug we found the Surfaces have with Aruba APs, which is low-impact but occurs frequently (several times a minute) and so is highly reproducible. More on the Surface bugs below, but I had also seen the Aruba bug where the client loses connectivity for 5 minutes or so, HE was disabled at the time. It's easiest to spot this in Airwave, there will be a period of no traffic transferred for the client. We didn't have any problem reports in the last few weeks of testing though, while running on 8.5.0.3, so maybe it was fixed? The user group (Maths teachers) were very good in reporting issues, although not always in a timely fashion. Our new production install is running 8.5.0.5 but I'll probably be upgrading to 8.6.0.1 before the teachers get back from summer holiday. I will strongly agree with the others in this thread who have posted that the support of your local partner and vendor TAC and account team should be high on your consideration. ThePoC was a tortured process, definitely not helped by the fact that the partner's engineers were in another state, and the local Aruba SE had just left, and a new one wasn't hired until October or so. I've also found Aruba TAC to be not great in my brief experience with them, certainly not compared to Extreme GTAC where I have on several occasions dealt directly with a developer, including one instance where we bisected code one evening to identify what change caused 2.4GHz to not work on AP3825s. The Aruba SE from another state did visit and let me know we should have setReversePathFwdCheckPromisc on the ESXi host, as we were seeing connectivity problems that were DHCP related, and that was the fix. It is documented, but only in the appendix of the install guidehttps://www.arubanetworks.com/techdocs/ArubaOS_85_Web_Help/Content/install-guide/virt-appl/appendix/nic-team-vswi.htm<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.arubanetworks.com%2Ftechdocs%2FArubaOS_85_Web_Help%2FContent%2Finstall-guide%2Fvirt-appl%2Fappendix%2Fnic-team-vswi.htm&data=02%7C01%7CTrent.hurt%40LOUISVILLE.EDU%7Cc4b73c8590bd4b5abdab08d79928e0cd%7Cdd246e4a54344e158ae391ad9797b209%7C0%7C0%7C637146273157195634&sdata=qXFnhtxo6Ae2qU1ac6dJaf55iYVjCMdwgibQeZ93cAM%3D&reserved=0> and not in the version that Google returns as the first result. That was 2 months of frustration right there, and partly why for the production deployment I insisted on physical controllers (although the mobility master is a VM). In terms of my (probably ill-informed) view of the competitive landscape, I've seen anAerohive demo after Extreme acquired them and was very impressed, but unfortunately they couldn't get me demo APs in time to do testing before exams started. I believeWiNG isn't going away, given the large customers who use it. Their latest APs run the same wireless code and can be managed byAerohive^WExtremeCloud IQ, WiNG or XCA, your choice. Cisco, well WLC is legacy and the 9800 series might be nice, but I'm yet to hear a good word about DNA Center. It's a beast, it needs 56 cores, 256GB of RAM and 2TB of SSD, and it's not supported as a VM (although people have made it workhttp://blog.vpnv4.com/dna-center-esxi-installation-guide/<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fblog.vpnv4.com%2Fdna-center-esxi-installation-guide%2F&data=02%7C01%7CTrent.hurt%40LOUISVILLE.EDU%7Cc4b73c8590bd4b5abdab08d79928e0cd%7Cdd246e4a54344e158ae391ad9797b209%7C0%7C0%7C637146273157195634&sdata=tS8QpBHaJDVHX4Ab5RQPD4PzrAvYsiEYFrFbgCQwnGc%3D&reserved=0> ). Meraki, I don't like their business model. Aruba, well, we chose it in part because Microsoft use it internally and that prevents them blaming the wireless when we're getting them to fix their drivers. Mist I've never used, Ruckus have always had great wireless performance and with CloudPath are getting their authentication piece in order. Which brings me to another point, consider the vendor's other offerings like management systems and RADIUS servers. I've already said my piece about DNA-C, and Airwave seems to have barely changed since I last used it 8 years ago. Extreme XMC is ok. I've run out of time today to expound upon the problems with the Surfacewifi chipset, but it seems there is an underlying problem that then causes different high level problems depending on the AP - I've seen three different badbehaviours on Extreme, Aruba and Cisco. We've got 200 Surface Pro 7s with Intel AX201 chipsets which I'll hopefully Thanks, -- James Andrewartha Network & Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph.

While every relationship with vendors have their ups and downs, my frustration with the Aruba is finally peaking to the point that I am considering making the enormous move to choose a different vendor. The biggest reason is with the 8.X code train, and bugs that we just don’t consider appropriate to use in production. It has been one thing after the other, and my extremely talented and qualified Network Architect (Keith Miller) might as well be on the Aruba payroll as much work as he has been doing for them to solve bugs. Just when we think we have one fixed, another one crops up. The big one as of late is with 515s running 8.5 code train. We have them deployed in one of our IT buildings. Periodically, people that are connected to these APs in the 5G band will stop working. To the user, they are browsing a site, then it becomes unresponsive. If they are on their phone, they will disconnect fromwifi and everything works fine on cell. Nothing makes an 802.11 network look worse than switching to cell and seeing a problem resolve. Normally, if the users disconnect then reconnect, their problems will go ahead (but I think they end up connecting in the 2.4G band). We’ve been working on this problem with them for months. It always seems as though we have to prove there is a real issue. I’m fed up with it. We are a sophisticated shop. If we have a problem, 9 times out of 10 when we bring it to the vendor, it is a real problem. I’m extra frustrated that due to issues we’ve seen inResNet on the 8.3X train that we don’t want to abandon our 6 train on main campus. To Aruba’s credit, we purchased around 1,000 515s last year (I think around February). When they could not get good code to support them on, Aruba bought back half of them. I asked for them to buy back half because I thought for sure with the 315s that we would have instead, the issues would be fixed by the time the 315s ran out. Not looking to be the case. So, with that rant over, we are seriously considering looking to move away from Aruba (unless they get their act together really soon). There are other bugs I’m not even mentioning here. For those of you that made the switch to another vendor, I would be curious how long the honeymoon lasted, what were your motivators, and were you happy with the overall results? Of course, this is a great opportunity to plug your vendor. As I see it, we have 3 choices…. Something from Cisco (we had Cisco long ago and dumped them for bugs), something from Extreme (we are a huge Extreme shop so this makes sense), something from Juniper (Mist). ********** Replies to EDUCAUSE Community Group emails are sent to the entire community list.
