We looked at MIST and Meraki, both great products. We feel our management went with ABC so Meraki it is. In a nutshell (and I can expand upon the “whys”) you get so many more features, flexibilities, with an included management platform with either one of these vendors. Controllers are expensive bricks. The only real reason to stay with controllers is if you do not want a cloud base platform.

The wireless-lan mailing list is always interesting, but this is by far the best thread yet :) We are a longtime Aerohive customer, and are aware of Extreme’s plans. Happy to talk about my feelings regarding Aerohive off-list. Whomever explained that startups are responsive at first, and start to lose their luster as they grow ... spot on. We are testing Meraki, Juniper/Mist, and Arista/Mojo. As always, some of the shine wears off once you get into the product. I’ve found some surprising RADIUS bug on Mist. Their initial support is responsive, but the resolution is ... forthcoming. We are a big Juniper shop, so are excited about their ability to monitor & manage (one day) our EX switches. If you start and eval, make sure you open tickets and explore how their support operation responds to requests (and bugs!).

May not be completely related, but we have had issues with newer AX chipsets that utilize NDIS 6.3 code set. Some of the advanced features had to be turned off as a work around such as packet coalescing etc. ALthough we have no 515’s in our environment, we are progressing to 8.6 (as per our SE) in the coming weeks and this does not make me comfortable. Any issues with the 300 series APs and 8.5x? May rethink and downgrade to 8.3x as it also seems to only support the AP103Hs as well.

Ryan, we have been experiencing some of the very same issues. Since installing 515s and resulting 8.5.x code in our offices (always our first step to any migration) we too have experienced unexplained periods of no connectivity. In most or all the cases I’ve personally experienced, I believe that I remain connected at an 802.11 standpoint but will have that 30 seconds to a couple of minutes of no IP connectivity. We have now deployed 515s and 8.5.x in one of our residence halls so I am concerned about their experience as well. Just before the holiday break we had a series of very high-profile outages that impacted our students leading up to and during finals week. The issue got so bad that our CIO had to issue a letter to students explaining the problem and what we are doing about it. This is the first time that this level of communication was needed in my 15 years at the UW using Aruba. We too are a heavy Juniper shop and have recently received a MIST demo kit. We haven’t done anything with it yet due to lack of resources, but if things continue on the current path we may give it a more serious look.

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 from wifi 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 in ResNet 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).
