Re: [WIRELESS-LAN] Anyone else seeing any issues in the fall with large classrooms and delayed connection times (Aruba 8.5.0.13)

[Ian Lyons]

Thanks Brad!
We noticed the same.  And do the same thing for general connectivity - turn off 
randomization.  The Crestron's, after the app is loaded and you go to screen 
share, (and all privacy settings are made) the client just times out and says, 
"unable to connect".  Session table indicate no response  same with traces.

Crestron can reproduce the problem in their lab with their own network. 
Soo, I'm thinking a bug. 

But am eagerly awaiting their response.

One thing I am struggling with is :Clustering is fun with the google home 
mini's.   EVERY single mini we have on campus has the client is on 1 controller 
(2 mobility controllers with 1 master) and the airmedia server (other device) 
is on the opposite controller.  We have base level airgroup set up (not where 
you can invite your friends to your group-I forgot what that is called)

That and Crestron's with IOS 14.7 seem to be our issues for this year knock 
on wood.

Ian,

iOS 14.0 introduced private MAC addresses. It was broken and devices spoke with 
both their real MACs and their private MACs. This caused the controllers to 
blacklist the devices for ARP spoofing. Once the timer expired, the device 
reconnected again for a while… 14.0 and 14.1 were broken this way. 14.2 fixed 
it and 14.3 worked fine. I have recently been receiving some tickets for 14.7 
and it seems like the bad behavior is back. Our solution to restore 
connectivity is to have them turn off the private MAC address setting for our 
SSID(s).

Thanks,

Brad

Same environment (6.x to 8.x) but no, radius is fine for us. We are on 535's 
with older 325/303's.   (we are AOS 8.6.0.10 which seems -knock on wood -very 
stable)

Our issue is with IOS 14.7 and Crestron Airmedia2's -I suspect the privacy 
settings are causing us issues.  Same Apple hardware ~ 14.3 or earlier is fine.

This is a stab in the dark.  With the University mostly shutdown since the 
Spring of 2020 (=not operating in standard mode and most people work from 
home), we got campus upgraded from 6.X to 8.X code base.  We’ve also installed 
many 515 series APs.  We are getting a large number of complaints in large 
classrooms that connecting to things like eduroam takes a long time.  Looking 
into the connection, we see many incomplete RADIUS challenges.  The general 
complaints are ‘we come into the classroom, and for some folks it can take up 
to 5 minutes to get connected’.  The odd thing is that our RADIUS 
infrastructure is very large, polished and load shared, and we can see no 
performance issues with any of the RADIUS servers.  We have begun reducing 
power in the large classrooms to make association issues better, but so far 
that hasn’t changed much.  We anticipate opening a ticket with Aruba, soon.  We 
do seem to see the most complaints in the big classrooms.  But I do keep going 
back to the RADIUS Challenges incomplete.  I know if no reason for those not to 
complete unless the connection is broken midway.



Has anyone else seen something like this?

Ekahau Update

[Ian Lyons]

Good Day Everyone!

Eric and I were happy to host a meeting with many of you about Ekahau last 
Friday.

We had a peak of 28 folks and an average of 18!  Thank you for coming!

The meeting started with introductions and that lasted about the first 20 min 
or so.
Steve (VP Global Sales) and Stewart (SE North America) were Ekahau 
representatives. Both started ~2 years ago

Then we segued into how people used the product:
Sidekick, AP on a stick, Design, Analysis, Engineering, and proof of 
engineering were the common threads.

Steve opened the introductions and brought up a point that Ekahau EULA was 
always 1:1. Members that have been using the product for 8+ years have evidence 
that it was initially concurrent users’ vs 1:1.  Further the "teeth" that made 
sharing the gear difficult became active in version 10.3.

Many schools, large and small, with disparate sized teams as well as healthcare 
indicated that there isn’t a 1 size fits all.

Pro’s and Con’s:
Some folks have deep pockets and will fund other active users.  Others stated 
that the device is used periodically and could be used by interns for site 
surveys up to proof of design and engineering validation by FTE's.
Use of a physical hardware license key was discussed:  On the one hand it makes 
it easier to tie to license to something, but that has the impact of requiring 
people to come into contact to hand it off.
The spirit of the device was a sporadically used tool but only 1 person at a 
time.

Some suggestions by the group and Ekahau, were a tiered approach of access.

Where we left things is that Stephen (SVP of Sales) will work with his 
management to determine an alternate EULA\connection model that will better fit 
our needs (those on the call).  We agreed to another meeting, ideally in 8 
weeks’ time to review Stephen's work on our behalf.

Steve was adamant that any problems by the group accessing a tool because of 
lock out/access please send an email to him (email info below) and he will help 
get you access to the tool again.

stewart.goum...@ekahau.com

*Any mistakes in the summarization are mine, on how the product works or ties 
together.  I do not have the product, so my knowledge gaps were a result of 
unfamiliarity of the product and a poor google search to educate myself.

Meeting Ended -Ekahau

[Ian Lyons]

The meeting ended and I will over the weekend type up notes and send them to 
the group.

I recorded the meeting but must figure out how that works to send it to a group.

It was a fruitful meeting with a lot of view points shared.

role-based access control (RBAC) Wed 5/26 from 11am-12:30pm EST

[Ian Lyons]

Please join us for a joint session between the Commtech, Netman and Wireless 
CGs as we explore modern network architectures that leverage role-based access 
control (RBAC) on the road to a zero-trust architecture.  We have a series of 
brief presentations followed by Q and active discussion. Our speakers include:

  *   Jon Young, Vantage TCG on a reference architecture for higher-ed 
networks, the value of and different approaches for RBAC and the shift to 
zero-trust
  *   Bruce Vincent, SLAC (formerly of Stanford) on the Stanford approach to 
leveraging IAM to achieve zero-trust networking
  *   Ken LeCompte, Rutgers will talk about Rutgers path to an identity-aware 
network as well as Rutgers use of analytics to provide key application 
performance and network insights


This extended joint session will take place Wed 5/26 from 11am-12:30pm eastern 
(90 min) on the same zoom the commtech group uses for our monthly meetings 
(https://zoom.us/j/852040219).  If you are doing something interesting with 
RBAC, zero-trust or network analytics and would be willing to present, please 
reach out to jonyo...@vantagetcg.com

Please also see NIST SP 800-207 for a primer on some of the concepts to be 
discussed at 
https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-207.pdf

Re: Wi-Fi and Covid

[Ian Lyons]

But the question becomes do we tag our students?

That is the sticky question.

Piggy backing on Lee, Felix and all the others… as someone who works for an 
organization that sells this stuff- WiFi location services are (IMO) useless 
(or nearly useless) for this type of contact tracing. The best you’ll get (per 
the manufacturers) is “a region” which is going to be a large square footage 
(not a single room) and not even necessarily on the same floor of the building. 
Nor even IN the building (could be outside) etc.

Having said that, if you want to try it, as someone noted there are plugins for 
not only Splunk but I know Aruba has an overlay they’re offering for free and 
Cisco has something that I hesitate to say is free but might be. So if you have 
time and resources and wanted to play, you have some no-cost options.

The best location solutions that may be integrated in to APs are BLE-based and 
out of that, the level of accuracy will always be orders of magnitude better 
than WiFi location but will vary depending on the other end – standard BLE 
chirping from things is not accurate. A BLE tag and/or phone with BLE and an 
app will be quite accurate.

We had the same discussions and the same conclusion, wifi is not good for this. 
  One reason is  you can’t trust the result.  You can’t say a person was in a 
certain building because they may have forgot their phone, not registered yet.  
 You can’t say a person was not in a building because many devices registered 
to a person are stationary and connect even when the person is not there.  So 
any data you pull is inconclusive at best.

I don't believe Wi-Fi is a good technology for this. It's nice when you can 
reuse existing overhead, but I don't think 2.4/5/6 radio is the answer. You're 
just begging for false positives.

Several vendors are trying to monetize COVID… the Wi-Fi part (in my opinion) 
falls apart fairly quickly in spots when you start talking it through for 
contact tracing- and usually to do it you may have to buy things you don’t have 
to round out the system.

Second Call for Virtual sessions..

[Ian Lyons]

Subject: Second call for virtual sessions

Just a reminder we are looking for feedback and suggestions - so if you have an 
idea for a topic or you find these interesting, please let us know.



Happy 2021 NETMAN (and WIRELESS-LAN). To help get the year off to a good start, 
we have been brainstorming for our next few virtual sessions.  Below is a short 
synopsis of a couple of the ideas we are considering, please take a look and 
let us know if these would be of interest.  Suggestions for other topics are 
welcome and as always we appreciate your feedback. Our goal for 2021 is to try 
and establish a regular cadence for our virtual meetups and we are aiming to 
have one every 6-8 weeks.  Once we have the topics confirmed, we will send out 
some tentative dates and get a poll going.



1.   IT Plans for the new normal - What is your campus planning for IT 
staff as we begin to move towards some sort of normalcy?  Will you return to 
campus full time, is remote the new normal, or is your school somewhere in 
between.  This virtual meetup will be an open discussion on how these changes, 
have and will continue to change how we operate.

2.   LAN/Campus designs and best practices -  Based on the recent activity 
on NETMAN, this virtual session will focus on LAN/Campus network design and 
deployment as well as a discussion around best practices.

3.   POE future state - The need or in some cases demand for powering 
devices from the network is escalating.  How are your organizations meeting 
this need? What are the challenges on the horizon: lighting, building/facility 
management systems, card access





As always, we appreciate your suggestions and feedback.


Ryan, Jeff, Ian and Eric

From:Jason Healy 
Subject: Re: Second call for virtual sessions

Similar to PoE, I'm wondering about multi-gig.  We're still 1g at the edge, 
which has been fine for any desktop needs.  However, with current Wi-Fi capable 
of going over 1g I'm not sure what I should be targeting.  I've been trying to 
"wait and see" what's going on but would love to hear some collective wisdom 
from those in the trenches.  I realize it's complicated (older wiring, 
single/dual ports, etc), but any advice for people refreshing their edge 
switches would be great.

The recent talk of zero-trust, network-trust, and authentication trust were 
very interesting.  COVID-19 has certainly upended some ideas about "trusted" 
networks with so many working remotely.  We've had to make changes to our 
systems to no longer assume that on campus == trusted.  I would be interested 
to hear more from people further down this path about trying to manage things 
more based on identity.

Probably less popular, but I'm always looking for IPv6 advice.  I'm just 
starting a push towards IPv6 internally here on campus.  We don't have enough 
public IPv4 addresses so we already do NAT, and I figured we should look into 
NAT64 and try to simplify our internal addressing.  I just turned on NAT64 for 
myself and am v6-only which has already uncovered some issues.  Am interested 
in anyone else that has started down the v6 road (especially dealing with 
vendors who continue to pretend it doesn't exist).

Thanks,

Jason

this need? What are the challenges on the horizon: lighting, building/facility 
management systems, card access….





As always, we appreciate your suggestions and feedback.

Re: [WIRELESS-LAN] Wireless Upgrade Project

[Ian Lyons]

I will provide a disclaimer that "things cloud" are not my favorite-in the 
regards that you have to prove that your network is not the problem before 
vendors truly commit in a down/crisis issue.  But the new world order is here.

Having said that, have people who have gone to the cloud have diverse end user 
client gear? Ipads,Iphones, IOT, PC,Mac etc.   Going back in time, I had Meru 
and RingMaster and with a pure PC client I never had an issue. As soon as the 
Macs etc (anything other than a PC) came online, chaos ensued.

Solution was to go with a newer (or better-sorry Meru)  on prem controller and 
when Apple did the "walled garden" fiasco, the controller vendors did a GREAT 
job un'effing what Apple did to us (again as a school in Sept/Oct) -just as 
classes were in full swing-with students who blithely get the latest greatest 
Apple software and then were not able to connect to the network

Now, a lot of time has gone by since then and almost everyone has a cloud-based 
product in the oven...with various levels of baking completed.

My question:
With the "lack of knobs" (our Meraki sales person kept saying that, but the 
intention I think was "it just works") in cloud solutions for wifi vs on prem 
controllers...  and a diverse (BYOD) environment are the cloud solutions solid? 
 Or has anyone felt that the cloud has been holding them back?

Just curious as the next evolution is here and I am genuinely intrigued on how 
things have evolved.

After 9 years of Meraki's cloud controller I couldn't imagine going back. (And 
I was a huge cloud skeptic...and still am to an extent).

Hello everyone,



Hope you’re all having a relaxing time off before getting back into the new 
year.  We’re looking for some feedback from those that have recently gone 
through a campus wifi upgrade/change.  From the non-technical perspective, we 
plan to communicate with our user base for all phases of the project.  Does 
anyone have any suggestions on communicating with the users?  Not so much on 
the how, but the information provided to the user, or requested information 
that can be useful.



On the technical perspective, has anyone gone from on-prem controller to 
controller-less and cloud management?  We will be conducting POCs with both 
Extreme Networks and Juniper Mist and as you may know, both of these solutions 
are Cloud managed solutions.  We are also doing a POC with Aruba, but there’s a 
little gray area there when it comes to controller-less.  What I mean is that, 
we were told we could go the route of Instant-AP with Cloud-Central, but given 
what we have about 1800 APs, we should prefer to go with the on-prem solution 
instead.  Here are some questions:



  *   I know that there are a few schools here that are Aruba Wireless 
customers, please comment on going to the newer version 8 OS (we are still on 
6).
  *   If anyone has any comments on going with or tested either Mist or 
Extreme, please do so!  With administrations now pushing to go to the cloud 
when possible, has anyone considered going controller-less?
  *   Has anyone considered AX as a driver to change, or waiting to see what 
happens with Wifi6E?
  *   While most wireless solutions would provide decent management dashboards, 
does anyone have any comments on which provides useful information for 
troubleshooting?  Mist provides many points of user-experience information that 
could help with troubleshooting issues, does anyone have feedback on that?
  *   For those that have experience with Extreme, has anyone employed that 
Fabric-Attach process to do without having to manually bridge vlans to the 
access points?  Was this really a game changer?
  *   With the Next-Gen solutions talking about all the analytics available, 
does that really help the system auto-tune power and channel properly?



I know this this a lot, any feedback will greatly appreciated,

That is correct. In 8.5 and 8.6 we introduced new chipset drivers which each 
added some missing 11ax functionality to our AP-5xx platforms.



8.6 is the release that delivers full 11ax functionality and Wi-Fi 6 compliance 
(all platforms are certified).



In addition, 8.6 is the first release to support the entry-level AP-504/505 
11ax platforms.

due to it being unstable. We had been running 8.5.0.5 without issues, no new MD 
crashes. Aruba stated the crash was due to a corrupt AMON packet. I 
reintroduced the MD that was offline without issues and then upgrade the 
cluster to 8.5.0.7.

Hi Everyone,

We are an Aruba wireless shop currently running ArubaOS 8.5.0.1 on an 
Active/Standby MM pair with 4 MD controllers.  Ever since we upgraded to the 
8.5 code we've encountered several critical issues requiring upgrades, and 
subsequent downgrades, between various 8.5.0.X versions. We have been on 
8.5.0.1 for the better part of the school year as it has been the most stable 
for our environment.  A couple weeks before the COVID-19 crisis, 3 of our 4 MD

8.5.0.7, which was released last week.

Are there any universities on this list that have recently upgraded to 8.5.0.7? 
If so, what has been your experience?

Combining the last 2 emails:

We use 303 and had used 205's in our dorms.  I  find them incredibly helpful.  
With the pass through port (if you have 2 wires in the room, you can keep one 
"as is" and pass it through) and then have WiFi and wired ports in the student 
vlan.

They are small and fit the needs of the students.  A bigger AP we found got 
wacked about a bit  more which required a site visit to fix it (reattach it).

We have cement block between rooms and have to do minimum tuning to adjust, 
however we did have one  building that I had to turn the power settings down 
-but I just created a group and set the power levels for that building 
different than everywhere else.   It did take some time once the students moved 
in to find the sweet spot.

All in all, our buildings it has almost been "set it and forget it"...

We’ve used a lot more of the hospitality models than standard access 
points, for us, 225’s.   We try to put one in each student’s room for a double 
or a single.  It gives their 10 or so devices a home, and provides wired 
interfaces if they want/ need to use them.  This also provides decent coverage 
is one goes down in a room, the rooms around them pick up the traffic.  The 
failure rate over the past 5 years has been very minimal, and we’ve been very 
happy with them, vice putting one access point in an area for a suite, or 4-6 
rooms devices to connect to it.  We getting ready to do a refresh of access 
points and will put even more of the hospitality units in, in houses/and a Dorm 
we didn’t put them in on the original install.

Hi Everyone,



I've been following some of the various discussions where people have mentioned 
using Aruba's hospitality access points and I e-mailed our vendor who we use 
about them to compare them with the IAP 215 units we deployed a few years ago 
in our residence halls.



I didn't seem to get a good explanation so now I'm asking this group.



For those who have deployed the hospitality access points, how do they differ 
from an Aruba you would put in an academic/administrative building?



Do you find you are putting more of them into a residence hall?



I'd toy with the idea of possibly swapping the IAP-215 units with hospitality 
units if the numbers were similar and we could move the IAP-215 units into one 
of our buildings with legacy Arubas although from what I think I'm reading, it 
looks like some of you are putting more into the residence halls than we have 
put (it's definitely not one access point for every one or two rooms based on 
the heat maps that were done).



Any thoughts would be appreciated.

RE: [WIRELESS-LAN] Cisco - Field Notice - 70253 - Wireless Client Fails to Associate: AID Error

[Ian Lyons]

Good point Lee

My experience through the painful upgrade/failure was that Cisco doesn’t know 
the pain point. They kept saying, point blank, we were the only people having 
issues.I immediately whipped out my laptop and showed them that others were 
having issues.  The blinking and open/closed mouths that ensued were comical 
until I realized I just went against everything they had believed. The end 
result was that my comment and documentation was ignored.  The data did not 
line up with their expectations and was ignored.  

Further, the new AC code is BRAND NEW.  The Aero code that runs all the older 
B,G,N ap's could not be upgraded to handle AC. So they started over...from 
scratch, without having bought a company.  I watched our Cisco team call China 
and made live edits to kernel code and have it compiled in real time and 
packaged up for us to test the next day to solve our problems.

My $.02, Cisco is a Marketing company and not an Engineering company (any 
more).  They cut their QA dept and rushed product out the door so they wouldn’t 
be lapped. Aruba already had been shipping for 14 months  a Wave 2 AC AP by the 
time a 1810/2802/3802 AP was rolled out. Even Belkin was announcing a Wave 2 AC 
AP the week our Cisco Ap's were shipped. I remember this as I was told it would 
be 1 month more before I got them and then they showed up.  I joked with my 
sales guy, did the Belkin announcement scare you?  We laughed

However, the initial order of 500 AP's that I received, did not work.  They all 
had bad code on them that prevented the devices from talking to the controller 
without manual configuration of the WLC on each AP.

I think the local Cisco people are GREAT.  Sales, Regional support, even TAC... 
 However, the institution itself (cisco) concerns me.  They rely on 
acquisitions to get new gear and struggle to incorporate the gear smoothly into 
their products. I am still waiting for Firepower 9300 to look anything remotely 
like a Checkpoint or Palo Alto NGFW Firewall.  They no longer are the market 
leaders in tech.  Aruba and Palo alto have superior products that work, right 
out of the gate.

One thing that Cisco has in its favor (my theory): most struggling customers 
don't know the scale of the code problems because they don't really talk to 
other customers. This list aggregates the pain and lays it bare for all to see, 
and it's very concerning.  I'd love to see AireOS scrapped, personally. And a

Typically they will fail after a powercycle or loss of power.
We are working with Cisco on this, but I'm curious if this is a more wide

RE: gaming on wireless

Which wireless vendor are you?

We had a lot of timeouts, lags and disconnects on Cisco gear (1810s)...   
-firmware was determined to be the cause and patches are ongoing  (it has been 
covered in length in posts)

Having said that, without a packetshaper like device/rate limiting  (we use 
Exinda's) the users are susceptible to bandwidth hogs and that could latency 
delays.  Remember, video download and audio are buffered and most web traffic 
can be rebuilt behind the scenes...  Gaming is one of the few things that

Subject: [WIRELESS-LAN] gaming on wireless

Has anyone received feedback from users about lags or drops while gaming on 
wireless?

We support gaming consoles on a "devices" SSID  (PSK with MAC auth). We're 
trying to resolve reports from a user with a new PS4 Pro who is experiencing 
issues while gaming. For perspective, it was reported that during a 3 hour 
gaming session the user experiences about 8 lags and 4-5 disconnects. Lags are 
described as freezes for a few seconds which auto-correct. Disconnects are 
described as the whole console losing connectivity and a "Retest Network 
Connection" is required to get it working again (though time might also be a 
factor in getting it back on).  Apparently most issues occur right after power 
up then smooth out (user turns on console just prior to gaming). Logs show the 
device jumps APs every now and then but we haven't been able to match this up 
to the user's experience yet.

Our eduroam and open (CP) SSID seem to working fine. Client density is not a 
factor and the user reports great speeds.

Are reports of gaming lag on enterprise wireless common or the exception? 
What's the first things to check to identify where lag comes from? Should 
device roaming introduce lag or can that occur lag free?  I realize we're 
talking UDP with gaming with no buffer so issues would present themselves more 
readily while gaming.. The PS4 is currently in user debug and we've asking the 
user to record timestamps to try to corroborate logged events. We have a TAC 
ticket open with the vendor.

Any shared gaming experiences or advice about how to make gaming consoles happy 
would be appreciated.

RE: [WIRELESS-LAN] Offline/Spare Gear Inventory Size

[Ian Lyons]

Fascinating.  While we are (we are engineers after all) beating the horse 
senseless, this is interesting to see how others arrive at their decisions.

I have always worked for schools where the budget is X.  Spend it on spares or 
get gear out the students, it is on us to make that decision.  I have always 
erred on the side of less spares more for the students….

However, don’t forget the basics –environmental variables.

Before I moved to Florida, I would have maybe 2-3 switches (we had 200 switches 
in use) and ~5 AP’s for the 1200 in use fail.  I never ran out of spares and 
had an exposure…

Until I moved to Florida.

Now, a good storm can blow up 2-3 switches in a day and 6-10 ap’s.  Worst storm 
to date was 2 chassis blades, 12 switches and 32 AP’s.

So all things being equal never discount the environment you live in and your 
mileage may vary, you know your environment better than anyone (or will know it 
after a year ;)   )

Also don’t forget the product, when I was a Cisco wifi shop (in Florida) during 
the Wave 2 refresh (which people are still talking about) I had a huge failure 
rate.  Since I went to Aruba I am down to (lightening hits aside) about 1-2  
failures a year out of 1500 aps.  Conversely, I do not lose Cisco switches at 
all (lightening hits aside)

Subject: Re: [WIRELESS-LAN] Offline/Spare Gear Inventory Size


I have a background in mathematics and addressed this question scientifically. 
The number of spares depend on the mean-time-between-failures of an AP 
(provided by vendors; e.g., Cisco’s 3702 APs have a MTBF of 325000 hours), the 
number of days it takes to order a new AP (k) and the risk you are accept to 
take that you have no spare AP available. If n is the spare factor (1 spare AP 
for every n active APs) and [cid:image005.png@01D3B072.CCF5AF90]  is the risk 
you accept that you have no spare AP available, this number can be computed as 
follows:

[cid:image006.png@01D3B072.CCF5AF90]

Here “ln” is the natural log, ln(2,71828…) = 1. So, in the case of Cisco AP3700 
and you accept an availability of 0.95 (5% of the time you have n spare AP) and 
it takes 6 days to order a new AP, you need one spare on every 116 APs.

I solve replacement items (of many kinds) with a formula that works for small 
and large deployments.  It works for everything from switches to toilet paper 
so I have used it for more than my day job.  It can and can be expressed in a 
spreadsheet like this "=CEILING(N1*M1,1)" where N is a column with the 
calculated need and M is a rate at which you need spares, or it is consumed 
before your next purchase.  The formula is sometimes calculated on a 
spreadsheet and sometimes it is just a rough estimate in my head.  Here are 
some example starting values for the M column.  Optionally you can add a field 
for the ceiling value to reflect things that are only available in quantities 
greater than one.  For example 10 for hotdogs and 8 for hotdog buns.  The 
formalization of this formula is adapted from one my manager used, so credit is 
due to David Allen.

Hello Alan,

My group recently added Wall Plate AP's to an entire dorm.  We had a 
similar issue with old cable TV Coax that supplied TV to the dorms.  Rather 
than abandon or remove it entirely we mounted bulkheads into the side of the 
boxes that allowed coax connections from the side while still allowing room for 
the wall plate AP to mount to the box.  The modifications required some 
drilling and a little cleanup but aside from that they could be completed 
quickly and with minimal effort.  depending on the size of the boxes you have 
in your rooms this may or may not work for you.

RE: [WIRELESS-LAN] upgrade from 802.11n to 802.11ac

[Ian Lyons]

Quick thoughts

Rip and replace will get you partially there (N to AC).

However, if you never planned for 5.0ghz “circles” for your AP’s (signal) a rip 
and replace will leave holes.

I suggest *not* using a physical survey..atleast in the traditional sense. 
(Donning my Nomex Flight suit for the flame war to follow  ☺ )
Use Ekahau or Airwave by Aruba and create 55db “circles” for your Aps with only 
the 5.0 antennae on and map it out digitally. I will not disagree that a 
physical survey is the gold standard…but to do it right you are paying a 
company to walk around and do a very extensive intrusive (aka expensive) 
mapping.  A virtual mapping of your space will get you about 90% there at a 
fraction of the cost.  And I do not know anyone in Education that is swimming 
in money…

This gives you the amount of Ap’s needed and their locations, which you can 
hand off these sheets to your wiring team/vendor for installation.

Having said that in the 2 colleges I have worked at, ~+45-50% growth is a 
ballpark number I have seen for going from N to AC.

I remembered that the 200 series uses their own.  We had a rough time when the 
AP-220-MNT-W3 came out and worked with Aruba to fix the slide mechanism and to 
get a usable patch cord with them.  One of our techs actually did a video of an 
installation and talked through the problems.  That made it to engineering and 
they sent us a prototype within a couple of weeks that worked much better and 
this is standard mount now.

I would recommend giving Aruba feedback and having your locals push it to

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

Subject: Re: [WIRELESS-LAN] Move In/Opening Week- Any Problems?




We were able to complete a couple of major changes in advance of our students 
moving in.



The first is that we completed an upgrade to Aruba 8.1 (brave, I know).  We 
have just under 1,300 APs running on it, mostly 2xx series with a handful of 
3xx.  We had to upgrade our controllers to a pair of HW-MM-5K mobility masters 
(we didn't have a suitable VMware environment to even try the virtual 
controllers), and a pair of 7240XM local controllers.  We had original 7240 
controllers at first, but we found that memory utilization jumped from 60% 
under 6.4, to > 90% in 8.1, so we went with the controller upgrade option as a 
low cost, quick turnaround fix.  We've had some minor glitches on the way, 
especially in the initial setup, but overall has been pretty solid, and hasn't 
caused any user complaints.



Our other major change was to create a new open wireless network that rolled up 
our previous onboarding and guest functionality, and also added in IoT 
capabilities, all backed by Clearpass.  It took quite a bit of work to 
straighten out the authentication rules, even after having a vendor come in and 
help us set up the initial framework.  We've seen lower uptake on the open 
network that we had expected - only around 200 out of 6,000 clients - but our 
best guess is that it's because we still provide on wired port per pillow, 
reducing the need for wireless on gaming and media devices.



Honestly, though, our biggest question is why our peak connected users has 
actually gone down from this time last year.  Previous we were holding steady a 
over 8,000 peak clients, but we haven't come anywhere near that yet.  We're 
waiting to see if people just haven't gotten around to finish registering their 
devices, or if there's some other factor that just hasn't surfaced yet.

So far, as we just finished installing the 1200 aps’, we are ~800 303h’s (1 in 
each dorm room) and ~500 325 Ap’s.

To make things more interesting, we also upgraded our core from 1 gb to pure 
10gb and changed our Firewall to the Cisco FTD platform.

So we truly have no benchmarking from last year but a lot of expectations!  LOL

on your network.  But home institution is 2000 miles away…

Black list MAC and call it a day?  Notify eduroam?  Home institution?  
Geiger-Counter person and tell them?

My guest account requires active phone number for user to get on the network.

Our campus isn't comfortable with an open ESSID without verifying the identity 
of the user, so that's the value of eduroam - identity.

Couple of comments:



  *   eduroam – using your point of “…most users can access what they want

in the day, this would facilitate quick access for a visiting educator who may 
be collaborating with someone locally and needing access to local resources. 
Today, in age of cloud-based collaboration platforms and access from anywhere, 
how important is eduroam over an open wifi network? With few exceptions, all 
the visitor needs is Internet access. eduroam doesn’t add value here, but does 
add complexity to manage.
  *   Location data – Yeah, this can have some value, but at least here, our 
emergency management moved to mobile-based applications that allow the user to 
opt-in to being tracked with the addition of panic-button-like services. I tend 
to shy away from using location-based services within WiFi where life-safety is 
involved. It can be a wonderful tool, until it doesn’t work that one-time 
management believes it should. In other words, finding a missing AV cart is 
different than a missing person.

This is a good topic, we are slowly moving towards a preferred EAP-TLS from 
PEAP-MChapv2 but not current date to force and perhaps never. The points made 
about why do we bother at all though are pretty relevant, most users can access 
what they want off-campus from whatever network they want, and VPN for more 
restricted access. So a properly segmented internal network providing 
appropriate access would be fine. *PSK/ open networks are theoretically ok.



At this point we are still confident that dot1x based auth is still the 
best way to go for users accessing our wifi, though this discussion has 
certainly opened my eyes a lot.





There's a couple of other reasons though why dot1x (which ever method) does 
have advantages to us. This may not be relevant to all, and there maybe 
better/other ways.



eduroam will break down via other methods, so you'll still need to manage a 
dot1x service no matter what. Then you have still have calls to SD because the 
service is now different when you want to use it, requires special setup that's 
different to on-campus.We've had Cloudpath a while, originally for PEAP config 
and now TLS. We do roll with a main SSID so our onboarding will configure our 
network  UofA and eduroam and users will just work wherever they go once done.



Occasionally for security reasons we use location data to track missing 
people. This is possible without auth to network data but it's better having 
that auth data. Same goes for identifying users acting inappropriately online. 
User ID to IP mapping is also fed into our firewall for web filtering 
exceptions (including group and personal)



Originally we went with Cloudpath to help users get configured easier which 
worked well (though this is less of requirement with auto-configs now pretty 
good), as well as properly since auto-config on OS's doesn't get the 
certificate right (so it ensure proper config). Configuring eduroam at the same 
time for windows was problematic however with PEAP (can't remember other OS's). 
As it would only save 1 SSID User info properly, so the second SSID it wouldn't 
save user ID and users would get prompted and not add the 
@adelaide.edu.au .. TLS resolves that little windows 
issue.



So for us one additional positive the EAP-TLS over PEAP but overall 
user-auth has its value.

The only caveat is that, like most Apple Products, are intended for consumers.

They had the devices wired where possible, and placed in specific subnets 
reachable from the clients but also with a predictable IP pattern which 
displayed on screen. They then documented "look for the address starting with

Glenn,

Cisco Prime Infrastructure (PI) product can assist with a lot of this diagnosis 
since it collects trend data including information specific to the client such 
as AP associations, roaming, RSSI, etc. It is a indispensable tool for getting 
to the bottom of reported client issues. If you don’t have it, I’d look at 
getting it. Your life will be far better.

That said, a few comments:

• SSIDs – have you confirmed that they are all setup identically? Lots 
of knobs can be turned for each SSID that can impact the client

• Do you have client band steering or load balancing enabled? In 
general, while clients have gotten better about honoring the trickery, many 
still don’t. In most cases, clients (especially Apple’s) do a great job now in 
picking the best SSID, so the need for controller tricks is diminished. In 
other words, disable these if you have them enabled and see if client happiness 
improves.

• Code – Get off of 8.0 (or at least get to 8.0.140.0). Preferably, get 
to 8.2MR5 where you will benefit from a lot of improvements, not only in 
client-AP compatibility, but additional features that will make your life a lot 
easier.

Depending on the project, smaller cabling contractors may not have anyone 
trained in autocad and not want to pay someone to make as-builts in autocad, or 
they don't want to take the time to input all the communication jacks and 
numbering.  Just put auto-cad as-builts in your specs as a deliverable and make 
it mandatory.  

If you are just talking about general building drawings, Architects are working 
for you and should absolutely provide all plans in PDF or Autocad, whichever 
you request.  Our facilities department will always get the plans in autocad, 
then we in IT get handed either autocad or PDF, but a request to the architect 
has always yielded whichever we asked for.

(The builders/contractors may not want to pass them directly to you, but 
through a proper chain of communication you should be able to request them, 
they should always be a deliverable of the project)

1810's are the buggiest.  And require MR5 (Which is not out officially yet)

But some bugs that hit the 2802's hard are resolved in MR5.  (users not 
connecting on Intel Chipsets) are resolved in MR5.
8.2.141 is the minimum I would suggest.  But MR5 will be out in the next 10 
days.-I have been told)


8.2.110.0 is the minimum code, however  Go to the newest code.  These AP's

I don’t think there is Nirvana.  Just lesser degrees of complaints.

Each environment seems to have unique challenges, both in the WiFi radio space 
*and* with applications and students “needs”.

Students also, for whatever reason, do not share their “This sucks” messages 
with helpdesk/staff.  They suffer in silence until it hits critical mass and 
then they explode.  I find walking the public spaces, cafeterias and asking 
people “how are things” is the best way to get a pulse.   Surveys also help,

You need both bands.  Build out your network for 5.0 ghz range circles around 
an AP (with some over lap) using a program to map out the wifi space and turn 
off extraneous 2.4 radios

Balance is achieved, users can connect on almost every device and there will be 
rejoicing  in the land.

2.4, and in many cases, users don’t even know it e.g. Apple’s Airdrop. You can 
minimize some of this by solving the reasons behind some of the interference 
sources i.e. install more WAPs to improve the service, reducing the rogue

Most of our residential is now designed around dense 5 GHz, and while 2.4 is

In the k-12 space, Cisco Meraki, Aerohive, and Ruckus continue to be the big

much of a dent. Those solutions also tend to come in at or lower than Ubiquiti.

One of the drivers for solutions such as Meraki is that from management’s 
perspective, the cloud-based platform and extensive support channel means you 
don’t need all those expensive FTE’s to run it, while at the same time gaining 
many of the enterprise features you care most about. The reduction of even a 
single FTE costing say $100K per year including benefits purchases a whole lot

If the lab needs to be completely isolated you’re going to want to hire a 
consultant to design a shielding system.  If you just need enough attenuation 
to mitigate significant interference, I’ve heard good things about the yshield 
paint.  You can add about 30-40dB of loss to a wall.  If you can keep your 
radios 40-50 feet apart, this should isolate them from each other enough that 
they disappear into the noise floor.

Keep in mind that it has to be grounded for maximum effect, and if I’m 
skeptical about the efficacy of the paint it’s mostly to do with this.  Good 
bonding and grounding is hard, and carbon paint doesn’t strike me as a great 
medium for reliable bonding.  That said, at Wi-Fi wavelengths ground quality 
shouldn’t be too much of a factor in attenuation as long as you keep antenna 
elements far enough from the walls to avoid near field effects.  But if the 
grounding isn’t effective you could end up with excessive internal reflection 
in the lab.  No problem if there’s a normal amount of absorptive material in 
the room, but could be a problem otherwise.

Just my two cents.

Subject: [WIRELESS-LAN] Cisco AP 'flash' bug

Over the last few months we've run into/discovered a Cisco bug and I was 
curious if any in this community have been seeing it as well.

In a nutshell, it appears the flash is being corrupted and the AP then enters a 
boot loop or fails to boot at all.We are apparently seeing a failure rate 
of roughly 10 APs per month.  My engineer's summary is below.

=

CSCvc74528 description is below, but it fails to take into account that 
occasionally the boot loop doesn't happen and the AP will just crash on boot, 
or fail to boot at all. Working with them to add some things to the description.

"APs go into boot cycle due to corrupt image, do not download new image from WLC
CSCvc74528
Description
Symptom:
APs reboot and when booting back up the image gets corrupted. The AP checks the 
WLC and sees it has the same image in flash and does not download the WLC 
image. The image on the AP is corrupt and therefor continuously reboots into 
the corrupted image.

Conditions:
2702I, 3602I and 3702I APs on a 8540 WLC running 8.2.141.0 or 8.3.102.0 code do 
not download WLC code due to same image on flash.

Bad flash in APs

Workaround:
Format APs via console with new image, holds for a few reboots.

It is generally good practice to have clients upgrade to the latest Intel 
driver before troubleshooting further.

In occasion, we have even used our RADIUS authentication logs to get a list to 
email wireless Intel users recommending they upgrade to the latest drivers. We 
have generally done this after a bad batch if drivers has been remedied.

Onderwerp: Re: [WIRELESS-LAN] Disabling LEDs on APs

We turn them off where we have the traditional ceiling mounted AP's located in 
student rooms.  I wish they had an option to leave the power LED on, but not 
have other LED's blink for network traffic.  My opinion is that the flashing 
lights would be annoying to me on the ceiling of a room I was living in, but 
the solid power light would be no different than a little light coming in 
through the window or under the door.  That would avoid the occasional trouble 
ticket where someone happens to notice that AP's in classrooms have flashing 
lights and the one in their room doesn't, therefore the one in their room must 
be broken.

This summer we installed Aruba AP-205H's in student rooms in 2 residence halls. 
 The lights on those are small enough and dim enough that I decided not to mess 
with them and have left them on.  So far I've not gotten any complaints, so 
either I'm right that they're small enough not to be annoying, or students are 
self solving the problem with tape or post-it notes, etc.

If so, what solution/appliance do you use and how is it working? As part of our

I appreciate your response. I’ll start looking at 8.2.121.11 to see if it makes 
sense for our environment. I’ll take the information you’ve provided and 
include it into my PoC justification summary. If absolutely required, I will 
separate these devices onto our unused secondary hot/standby cluster, but my 
preference is a single (stable) code version throughout our environment. We may 
recommend that they purchase a third hot/standby cluster for their environment 
since their license counts are going to triple in most buildings. Since they do 
not manage any of their infrastructure, they’re not aware of these types of 
issues and just expect things to work and be cost effective.

Again, thank you for the useful information.

RE: [WIRELESS-LAN] Question about Cisco 1810w APs in residential buildings

[Ian Lyons]

No one has complained about “glowing” in the 5 years I have put AP’s in rooms.  
I think it is more in line with “I have an AP in my room, I’m better than you”  
“Faster WiFI!”

Going forward, I have worked in 2 schools, we did the “G” rollout down the 
center of the hallways.  While still having “a port per pillow” in a room.

If a full sized AP is ~$700 and wiring in a dorm (pain in the butt that it is, 
due to when we can run wires) is about $1000 per location (outsourced), I 
cannot fathom not using an existing network drop (They are cat5e) for a 
hospitality AP (Cisco 702/1810 or Aruba 205h) that is ~$300.

Long term, I think it just makes sense (AP’s in a room).  As the devices and 
perception require an AP closer to them and desire for better thruput 
increases, as does the quantity of devices each student has.

It is a bit early in the year and Spring Semester will probably be a better

Not to speak for Hector, but I think the concern here is physical damage. 
That’s an interesting topic as here we’re used to ceiling mount APs that are 
generally out of the way. However, we have a few hallway phones (admittedly 
higher on the wall), and probably 15%-20% get damaged or knocked off the wall 
every year.  Would the students be any more careful about APs at outlet or desk

We've deployed around 150 or so in one complex although we're fortunate to have 
them mounted just to the left or right of the door at about waist level.  Still 
have the concerns about getting knocked around with furniture, but so far so 
good.

Hopefully the DNS discovery issues have been resolved as we have another 180 or 
so going in this winter into a new 700 bed building.

It actually helps limit the signal propagation (2.4).

One of my biggest concerns has always been the height at which these WAPs get 
installed (as you mentioned, 1.5ft). In most of our residential buildings, the 
data ports happen to be right behind desks that are provided by ResLife and the 
desks have covers in the back that essentially would bump against the WAP. Not 
to mention the fact that as furniture gets moved around, there is always the 
potential of knocking down the WAP. I wonder how has already deployed them in a 
similar fashion and what the experience has been?

If you end up using them, I'd be curious to see how things work out.

All,

Our housing department wants us to look at these for wide-scale deployment in 
11 residence halls within the next 2-3 years due to cost reduction in cable 
installation with our previous designs. This will be a one AP per room 
deployment utilizing current wiring infrastructure, where Aps were previously 
in the hallways (2600, 3500). We're planning to configure the cells to a lower 
transmit power as well as assigning channels based on zero occupancy with 20MHz 
channels. Our ability to get into these buildings in order to resolve rogue 
issues is severely limited already because we are required to have a 
Residential Technician (from the housing department) with us when visiting 
student rooms. That's only going to get worse when we lose visibility that we 
currently have with our current deployments in the halls. We're also not 
planning to enable the ethernet ports because those aren't in scope for the 
Proof of Concept due to crashed timelines provided by the department.

We're currently running 8.0.133.0 and have been incredibly stable (no AVC, no

Not to speak for Hector, but I think the concern here is physical damage. 
That's an interesting topic as here we're used to ceiling mount APs that are 
generally out of the way. However, we have a few hallway phones (admittedly 
higher on the wall), and probably 15%-20% get damaged or knocked off the wall 
every year.  Would the students be any more careful about APs at outlet or desk 
level?

RE: Question about Cisco 1810w APs in residential buildings

[Ian Lyons]

8.2.120.11 is the minimum version I would recommend.  1810 (in my opinion) came 
out of the factory not completely baked.

We bought the first batch of 1810's off the assembly line and they did not have 
a means to talk to the controller (DNS would not work nor DNS options). We had 
to manually point them at our controller.  However, *if* you bought a recent 
batch (after Sept) I have been told they have reimaged all the AP's at the 
assembly line and that issue has been resolved.

Other issues we have seen (and in 8.2.130.0 most have been resolved) are AP's 
rebooting frequently.  More recent code upgrades have fixed that issue, however 
we are still having an issue with the 1810's and the wired ports.

As to redundant WLC's I would go to 8.2.121.11 at a minimum, there is a WLC 
issue with SSO as well as the 1810 issue that I found (the hard way) to be the 
minimum version to start at.

Things are improving.  However, 500 1810's deployed = challenging times.

The good news is, is that the students memories are short and I expect once 
these issues get ironed out, smooth sailing.

If you have *any* 2802 or 1810 devices, I *strongly* urge you to upgrade.

We see the same issue (code 105) here. Upgraded from 8.0.120 to 8.0.133 with no 
help. With "show client ap 802.11b AP_name" command, I see a lots of clients in 
idle state, also these idle clients will not be cleared out by the idle or ARP 
timeout. I noticed all these clients are inter-controller roaming clients. Then 
I shuffled some APs among controllers to minimize inter-controller roaming and 
also use scheduled job from PI to reboot some APs weekly to clear out the idle 
clients. Now I do not see this error anymore in our environment.

You may be hitting this bug for the 105:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuw34201

Fixed in 8.0.135 and later.

107 seems like it may be similarly related to APs hitting a max limit as well.

I would consult Tac before upgrading, but seems like there are a couple active 
bugs that could be triggering this.  8.0.140 has a long list of resolved 
caveats that might be worth exploring.
