Re: [WIRELESS-LAN] Update on our Aruba solution

[Amel Caldwell]

We have a small installation of 515s running 8.5.0.5 and have experienced the 
same behavior that Keith described.  So far, mostly anecdotal data but we are 
starting to gather data and troubleshoot this with Aruba as well.

Do you mind sharing what version of code you are running currently? I think you 
mentioned 8.5.0.3 in the initial thread, but you mentioned the upgrade to 
8.5.0.5 was recommended by Aruba. I would be curious to know if the tiger team 
saw these issues on 8.5.0.5, as we just upgraded to this version over the break.

Subject: [WIRELESS-LAN] Update on our Aruba solution

All,

Since the thread generated significant interest last week, I wanted to let you 
know how Aruba responded.

After hearing of our issues, Aruba sent a tiger team (5 or 6 folks) that came 
in to work on the bugs.  We had a punch list of things to work on.

On the top of the list was the 515 performance issues.  This is where people 
would stay connected, but data wouldn’t flow for a period of time.  The 
symptoms were reproduced many times during the week with everyone present.  
Aruba found a bug in code that does not handle queuing properly in certain 
circumstances.  They produced code to fix this issue, but we cannot confirm at 
this time if this will resolve what we are seeing….  We saw a similar symptom 
immediately after putting the fix on the AP.

After seeing the same symptom immediately after putting on the hotfix, they 
realized that someone on the team has an intel AX adapter which has significant 
issues with OFDMA.  It can essentially wreck the airwaves for other clients.  
The solution is to TURN OFF OFDMA on AX access points until Aruba releases a 
build that can selectively ignore Intel OFDMA (while allowing others).  I have 
a release from Broadcom on January 6 speaking to this issue, so they aren’t 
making that.  I confirmed it with a separate wireless vendor that Broadcom has 
had some issues on the OFDMA front.  I plan on keeping it off for likely the 
next year as we don’t really have a significant quantity of ax clients to make 
it work the hassle at the moment.

Re: [WIRELESS-LAN] Who has transitioned away from Aruba, and why?

[Amel Caldwell]

Hi Keith and Michael—

That is correct.  We recently experienced a meltdown on our campus  due to this 
very issue.  We had to enable cpsec and that seems to have fixed the issue then 
snow hit our area and we have not hit anywhere near the normal level of traffic 
so we are, at this point, “cautiously optimistic”  .  I don’t consider this a 
permanent fix and have been assured the fix to place PAPI traffic into separate 
queues will be in 8.3 and 8.5 code trains.

I would warn that you need to be careful because this causes control traffic 
from the AP to be sourced through the IPSEC tunnel and over the controller 
uplink.  If you have IP Spoofing deployed then you will have to allow APs’ IP 
traffic.

Hi Michael,

Currently we do not and yes, that is the situation as I understand it. The PAPI 
traffic between APs and the controllers use the same queue that the controller 
to controller heartbeats use. Enabling CPSec moves that traffic traffic to a 
different queue.

We’re expecting to enable CPSec in Resnet today.

Do you run CPSEC on your APs?   I've heard that non-CPSEC AP connections can
contend with the controller cluster heatbeats and cause disconnect.

No not related to AirGroup, but we’ve had problems with AirGroup server leaks

The other problems are related to the 515s and we are suffering from cluster

reasons.

Re: [WIRELESS-LAN] Who has transitioned away from Aruba, and why?

[Amel Caldwell]

I have direct experience with what Ryan described.  A couple days after X-mas 
when there were very few people in our building, I lost connectivity on my 
iPhone, 2 Mac Book Pro (different vintages), and a wireless Avaya desk phone.  
At the same time an engineer across the hall lost connectivity on a Windows 
laptop and his android phone, plus and Aruba Cape Sensor experienced the same 
thing.  On the clients involved there was no indication of there being a 
problem and they appeared to be connected, just no IP connectivity.  I did see 
that the Cape sensor roamed from the AP where it had -62 signal to one that had 
-89 and that is when we lost connectivity and 3 minutes later everyone roamed 
back and we again had connectivity.

So as Ryan described, no common drivers, we still see the SSID, we just get no 
traffic and it clears with no intervention.

Ryan, we have been experiencing some of the very same issues. Since installing

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

We too are a heavy Juniper shop and have recently received a MIST demo kit. We

We also have an instance of the Ookla speedtest at the University of 
Washington.  One thing I notices is for clients on private IP space, the 
speedtest shows a NATed IP, even though the server is on campus.  This is 
because not everything is local.  Anyway, having someone send me a screenshot 
or tell me their IP address is the NATed address is not that helpful.  I

Re: [WIRELESS-LAN] Aruba / HA / And ARP broadcasting during controller losses

[Amel Caldwell]

Hi Ryan—

We have a similar setup, our main campus has around 7,000 APs with one master 
controller.  We have separate AP management VLANs in each of our buildings (we 
don’t span VLANs across multiple buildings here) and use DHCP options for 
master controller discovery.  We still get a ton on pings looking for a lost 
controller but the infrastructure handles the pings better than they do ARPs.  
It may help if you separate the controller management and AP management onto 
separate VLANs and use DHCP options; this would have the effect of changing the 
ARP to ICMP traffic and hopefully that would be enough to weather the event of 
a lost controller.

I do wholeheartedly agree that Aruba implenting a back-off mechanism to lessen 
this impact over time would be great.  I am also not real happy with how Aruba 
implemented the “heartbeat” option for the standby-controller to verify the 
primary is still up and it really does not scale well.

Based on design recommendations from Aruba, our 10,000 AP network has been

approximately 5,000 access points, and the controllers and access points share 
the same VLAN.

What we have noticed is that if we lose a controller (or shut it down for 
maintenance or a move), the access points start ARPing like crazy for the 
downed controller.  We can see in excess of 1,000 ARPs a second in the 
management VLAN.  This has the negative side effect of causing CPU spikes 
across certain models of switches on campus, and we lose management to those 
switches.  User traffic doesn’t generally seem affected, but SNMP monitoring 
ceases.  We are wondering if others have seen this, or designed around 
mitigating this.  This is definitely a scaling issue, and we feel as though 
Aruba could develop back-off mechanisms from allowing High Availability to 
essentially DoS parts of campus with ARP.

Thanks!

No, we did not make the video available publically.  I am not sure the person 
who made the video would be comfortable with it being publicly available; I can

Amel,
I actually was referring to the JY706A AP-220-MNT-W3. In the 200 series APs, we 
have only purchased the 22X models for indoor use. I thought all of the 2XX 
indoor APs used the same mount and didn’t realize there is a JY705A, as well as 
a JY706A. Is the video you refer to publically available? If so, would you post 
the URL?

Hi All,



I wanted to share our first look at the JY705A AP-200-MNT-W3.



The slide latch is on a plate that comes out of the main body of the mount and 
until it’s removed that plate obscures the screw holes we would typically use 
to attach the mount to the mud plates with two machines screws. These two 
pieces are held together by screws that thread into the main body of the mount.



So the first step of installation of this mount would require removing this 
slide latch plate to attach the main AP mount body to the box. The second step 
would be to fasten the slide latch plate into the main AP mount body with four 
small coarse thread plastic screws, then finally attaching the AP. Because the 
main AP mount body needs to be fastened down first you can’t assemble it ahead 
of time. If the AP is overhead, you’d have to fasten in the slide latch plate 
overhead with four fiddly little screws.



The design does allow an installer to rotate the latch plate by 90° so that the 
AP release button might be more accessible after installation. This is 
obviously why they separated the latch plate and main body. Other than that it 
complicates the installation and adds steps that wouldn’t be required with a 
single piece mount.



Probably more of a cautionary tale. Don’t get them unless you need them or your 
installers may hold a grudge. I’m thinking these are a none starter and we’ll 
look at stocking another model.

Subject: [WIRELESS-LAN] Outdoor WiFi infrastructure experiences/strategies?

There is quite a bit to think about here, so in an effort to keep the scope in 
a hopefully reasonable place, I’d love to hear what others are doing regarding 
the infrastructure (not so much the networking and RF at this point) and 
overall campus strategy.


  *   Has anyone already developed a comprehensive campus wide strategy?

 *   We have an informal strategy and have been trying to work with our 
Campus Architects to formalize it and get something we can work off of and 
expect to be allowed to deploy.  Our idea is to agree on a small number of 
options for deployment that is pre-approved and then ask to use “Option A” at a 
particular site.

  *   Did you leverage buildout of cellular micro sites?

 *   No.

  *   What kinds of locations/areas do you find that your users get the most 
value/appreciation out of the service?

 *   We are wanting to have complete coverage across our entire camus, but 
the priority areas are major walking paths, and green spaces.  We are starting 
to discover in heavy foot traffic areas people walking by can become a sort of 
DoS on Wi-Fi inside the building because they associate to indoor APs as they 
walk by and sometime max out the number of associations allowed.

  *   Where do you physically install the AP’s and has that kind of deployment 
been successful?

 *   rooftops with directional antennas?

*   This is how most of our outdoor is deployed, but from a tall 
building there is a lot of signal loss just getting down to the ground and you 
want to be careful not to have the signal bleed back into the building too much 
and impact indoor coverage.  We also had to turn of “short-guard interval”.

 *   exterior wall mounts?

*   We have some of this type on our new residence halls and I think 
from a performance perspective this is a much better scenario.  We have been 
allowed to build in the external wall mount on our residence halls because they 
are governed by our Housing and Food Services; on campus buildings it either 
adds too much cost to projects or the aesthetics don’t work and it has been 
much harder to get approved.  Existing buildings this has been a non-starter.

 *   building canopies/overhangs?

*   One or two sites, but this has been a hard sell for the same 
reasons as external wall mounts.

 *   light poles?

*   This would be ideal, but we have so many different types of 
lighting it is nearly impossible to find a consistent solution.  After trying 
to work with our campus architects the new lighting standard makes it nearly 
impossible to put any wires inside the pole or mount any antennas.

  *   Ideas on aesthetics/concealment/physical access?  Ive heard of a use-case 
where the AP has been buried in flower beds also small antennas in light pole 
globes.  How else do you hide the gear?  Any good/bad experiences with custom 
enclosures and/or external antennas?

 *   I have been trying to push the idea of using bollards, either close to 
buildings or other foliage areas.  This would allow for interior APs (if they 
meet regulatory specs) or eternal APs and puts the AP right at waist or chest 
level.

  *   Experiences (suggestions) with providing power for areas out of 802.3 
distance specs? Anyone use the hybrid fiber/copper products that are on the 
market?

 *   We have used Commscope’s hybrid fiber and have been really pleased 
with it; it save a lot of costs on the install and I find their product is 
really well designed and flexible.  Their system can fully power an AP-275 up 
to 1 mile and they can fully recover power with up to 50% loss.

  *   How do you plan pathway build-outs?   Do you leverage facilities and/or 
landscape construction to install conduit, etc?

 *   So far, we have been taking advantage of construction projects, but 
are considering using the mole tunneling to try to get into some areas.  We 
also have underground tunnel system we use to pull connections most of the way 
and then do what is needed from there.

  *   Any experience with putting hardened equipment (switches/aps) in 
underground enclosures?

 *   No direct experience with this but there are a number of vaults that 
can be buried and are designed for this purpose.
I could go on and on with questions but I’m really looking for general 
advice/suggestions/creative ideas/war stories from others who have already gone 
down this road.

Hope this helps.

Re: [WIRELESS-LAN] Clearpass Bug - Posture and Profile Data update

Fortunately for us, we are still on 6.6.5 and we were not affected by this.  
This did make me think about how fragile the operational state of the ClearPass 
cluster can be.  Looking through my event logs, I see the AV/AS updates 
happening 20 plus time a day and they hit all of our servers simultaneously. 
So, I am curious how others deal with this.

Do you monitor process status on each of your individual servers?
Do you have automated mechanisms to restart stopped processes and notify 
engineers?
If so, what methods do you use?

Did they say what the release will be?  Will it be 6.5.2.1 or are they going to 
expect you to jump to 6.5.3 or 6.5.4?  We often request fixes to be put in 
older versions to minimize risk of going to a whole other train of code.

Re: [WIRELESS-LAN] Issues with Aruba bracket JY706A AP-220-MNT-W3

[Amel Caldwell]

Hi Jethro--

When the AP-220-MNT-W3 was first released, we got some and they were nothing 
but trouble; the jumper that came with them was too tall for the mount and the 
button would stick.   We worked with Aruba on the jumper design that comes with 
them and also the button issue.  Aruba fixed both issues and the newer 
AP-220-MNT-W3 are much easier to use now.

The easiest way to tell is by the jumper.  The jumper should have a low-profile 
connector and is a flat cable; the older one looks like a standard CAT5e cable. 
  If you have the older one, I would follow up with your local SE and try to 
get them swapped for the “fixed” version.

Hello all,

We are relatively new to the Aruba world, but for our first major 
deployment (replacing other APs) we're going for JW797A AP-315 with the 
JY706A AP-220-MNT-W3 White Low Profile Box Style Secure Large AP Flat 
Surface Mount Kit.

We'd originally done some testing with (I)AP-225 and bracket 
AP-220-MNT-W2W.

AP-220-MNT-W2W was discontined in favour of AP-220-MNT-W3.


https://community.arubanetworks.com/t5/Wireless-Access/What-is-the-difference-between-the-AP-220-MNT-W2-and-AP-220-MNT/td-p/274771

Now, as we did a rehearsal for the replacement, we discovered that the 
AP-315 would not fit the AP-220-MNT-W3 bracket.  The slots for the 
mounting lugs of the AP are slightly narrower in width, and so the lugs do 
not fit.

Is this a common problem, or perhaps do we have a bad batch?  Can anyone 
corroborate?

It is possible to make it fit by some juducious shaving of the plastic, 
but that's clearly not desirable.

The AP-315 fits fine on the AP-220-MNT-W2W, although because it is a 
smaller AP it looks a bit odd.  And AP-220-MNT-W2W is EoS regardless.

Jethro.

Re: [WIRELESS-LAN] EDUROAM Service Fees Thoughts

[Amel Caldwell]

This is what the letter said regarding fees:

“eduroam Invoices and Fees
Internet2 will continue its current practice of covering the eduroam fees as a 
benefit for its higher education members. Just for your information, the fee 
structure for non-Internet2 members (and Internet2 members that are not higher 
education members) is $0.10 per user (based on IPEDS "total enrollment" data) 
with a minimum charge of $400. “

Internet2 higher ed institutions will have to pay a one-time fee of $700 and 
the fees will be continued to be covered as part of the I2 membership.

Other institutions do have the per-user fee.

The recurring service fee is $.10 per enrollment according to IPEDS with a

Agreements must be signed by 7/31/2017 in order to ensure no 
discontinuation of services.

Unless I'm reading the communication incorrectly, that is the summary I 
concluded from it.

My understanding is that there are no recurring fees for Internet2 members, 
just a one-time registration fee.
