Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Sweetser, Frank E]

Speaking as yet another site that saw huge improvements going from in-hallway 
to in-room, there's another factor that hasn't been mentioned very much yet - 
the client side radio.  Even if you dump all kinds of special sauce on the AP, 
like Xirrus multi-sector or Ruckus Beamflex, you're still going to be dealing 
with the same low power, crappy antennas and radios in your clients.  That high 
end $2k AP may be able to push a signal through concrete, but your user with an 
iPhone 5 is still going to be out of luck.


You're better off going with even a bottom end AP per room, or every other 
room, than high end ones in hallway.  Check out the hospitality models, like 
the Aruba 203H (or whichever vendor you use - most offer something comparable). 
 They typically feature a few wired ports powered off of the AP uplink, so if 
you already have active ports you can just re-use them rather than having to 
light up new ones in every room.

We used to do APs in the hallways years ago, but had similar complaints that 
you are receiving.  We've been doing in-room APs for the last 5 years and the 
complaints have dropped significantly.  We are an Extreme Networks customer and 
use their AP7502 
(http://www.extremenetworks.com/product/wing-ap-7502/)
 in our residence halls.  We used to do an AP for every 6 rooms; we now do an 
AP in about every other room.  I foresee a day when we have an AP in every room.

eduroam Requests Not Received at Border Firewall

[Curtis K. Larsen]

Hi Guys,

I have an issue when I send requests via the eduroam website realm test tool 
(eapol_test) and for some of them I get a "No response" or "Timeout" result, 
and other times a success without changing the client configuration parameters. 
 Doing a tcpdump at my server and matching up errors from the realm test tool 
sometimes not a single packet is seen from the eduroam servers, other times a 
partial number of packets are seen, and sometimes all packets are seen in which 
case my server returns an Access-Accept and all is well.  

I then go to my border firewall and see the same matching packet counts as at 
my server.  Basically, I run the eapol_test from the website and sometimes 
nothing is seen at my border firewall, sometimes half the normal 
access-challenges occur, and then when I see the normal number of packets there 
is a corresponding number of packets on my backend server and a successful 
authentication at my server.  One thing that is interesting but maybe not too 
relevant is that it seems to affect remote EAP-TLS connections twice as often 
as remote PEAP connections ...but both are sporadic.  Local authentications on 
the other hand are fast and successful 100%.   I am finding myself 
unfortunately needing to troubleshoot the internet at this point.  Anyway, I 
guess my questions for the group are:

1)  If you run the tests from the eduroam realm test tool are the results 
consistently successful against your servers?
2)  Is anyone aware of maybe a problem with the way the website runs the 
eapol_test script that sometimes would cause no request to even be sent?
3)  If two or three Access-Challenge requests are sent from my servers to the 
eduroam servers, I see them leave my border firewall, and I never get a reply 
back what am I to do?


Thanks,

Bit us at 2:38 AM, took until 5 AM before I got called.  By the time I got to

Pretty tempted to block CP access to the CP update site so that we can open it

First, get the APs out of the hallways and locate them where the users are. APs 
in hallways can hear each other better than they casn hear clients.

Second, work with your Aruba account team to optimize your RF environment for 
the different building structures. We have based our RF adjustments on this

[Osborne, Bruce W (Network Operations)]

Our Aruba SE alerted us but we are running 6.6.5. Out servers already had the 
fixed version anyway.

For RADIUS monitoring we use Nagios and monitor twice. One services uses an 
Active Directory service account, and a second one uses a ClearPass local user 
account. Aruba recommends this to assist is problem isolation if there is a 
failure.

Unfortunately, we were hit by the same bug as Chad and possibly a few others on 
the list.  It looks like the problem affects Clearpass customers running 
6.6.7+.  We struggled to find a fix early this morning and finally got services 
up around 7:15 am pacific time once we identified the issue.  But until we were 
noticed the problem and resolved it, we were down for wireless access across 
campus for 6 hours due to this Clearpass bug—the issue started at 1 am for us.

This brings up an obvious need on our part to check our Clearpass servers from 
a 3rd-party tool for authentication successes and failures.  I think we’ll have 
to use a Nagios plugin (or something like it) for radius authentication checks, 
which I didn’t expect we would need to do.  As for monitoring other processes 
on individual Clearpass servers, I don’t have a ready answer on that one.

However, this does bring up a desire on my part related to vendor participation 
on the list.  I know we have some HPE/Aruba employees that participate on the 
list and I think the Wireless-LAN group would be a perfect vehicle for them to 
disseminate information to customers that could be affected by known issues, 
particularly ones that could impact services to your campus.

When we had the issue this morning, one of the places I looked was the 
Wireless-LAN discussions to see if anyone was affected by problems with 
Clearpass.  I didn’t see any (until Chad posted later) and so we thought our 
issue was more isolated.  We wasted 20 minutes of valuable MTTR time collecting 
Server Logs when all we needed to do was start the “Policy server” service.  
However, if I had seen a post from HPE/Aruba to the Wireless-LAN list about a 
possible problem affecting many customers, we could’ve started working on the 
real issue earlier.  Putting in a  TAC case related to a critical 1 issue is 
something we generally wait to do if we can’t find a quick fix on our side.

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?

I like the one wall rule Joel.  That's a great way to state it and I never
though to express it that way.  We still have AP's in hallways in some
locations but they are not penetrating multiple walls before it gets to the
user.  We also have the one per suite issue with old construction.

In regards to monitoring services on CPPM we send SNMP traps from CPPM to
our NMS. Traps for a service that starts or stops get forwarded as an email

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Coehoorn, Joel]

My experience is you can get good signal propagation without complaints
going through one wall, but not often more. We go every other room in a
checkboard pattern for traditional rooms, also using (formerly
Motorola=>Zebra) Extreme AP7502's, which I love (it's nice to finally see
someone else here using this under-rated line), and we're doing well enough
I'm considering going to an every-third-room deployment strategy the next
time I update a dorm, which for a traditional dorm still meets the "one
wall" rule.

The every-other option is working well even in an older building that has
crazy poured-concrete interior walls like I've never seen elsewhere. The
original construction is a metal chicken wire mesh stretched from floor to
ceiling that is **murder** on wifi signal, with a heavy concrete mixture
poured around it. The walls actually curve inward a bit as they reach the
junction with the outside wall.

In the case of suites/apartments, I try for one AP per suite (using AP7522
on the ceiling in the common room/living room), but we have two buildings
that were put up just a year or two before wifi was a big deal, and there's
no good way to get network drops into the ceiling... no plenum, and the
existing cable paths run in the outside wall between the brick and
insulation layer, and I have next to no way to change any of it. I wish I'd
been here when they were constructed... I would have insisted on drops into
the common spaces. These buildings use a hybrid between hallway and
in-room, with an AP7502 in every suite, plus some hallway APs to augment.

RE: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Ferguson, Michael]

We tried the Xirrus in the hallway approach with some of our Residences a long 
time ago and got burned by it.  Even with their multiple sector AP’s that 
Xirrus has with their higher-end products that have directional gain, they 
still didn’t penetrate enough into the rooms to provide adequate coverage.

In our case, due to all the fire-rating in the doors and plumbing/ducting in 
the room walls to the hallway, we have between 10-15 db loss trying to 
penetrate in the rooms.  If you had an AP right outside your room, you’d be 
lucky to get a -65 at 5G if the door was closed.

You really have to do AP’s in the rooms if you have the attenuation we have.  
Once we installed AP’s in the rooms, the attenuation between rooms and between 
floors was significantly less.  So with newer buildings, we could do a 
checker-board design of an AP roughly every other room, checkered in opposite 
rooms on different floors.  The goal is that no resident is further than 1 
wall/ceiling from an AP for good 5G signal coverage.  For older buildings that 
have cement walls, we use the hospitality units and install an AP in every room.

This did increase the cost of deployment for us, but unfortunately it’s a 
necessary cost if you want adequate coverage to service your residents.  That 
said, there are some savings.  Going with more AP’s does reduce our long-term 
maintenance for channel selection and cell sizing.  We can better rely on our 
wireless system to automatically tune itself.  But if you go with a Hallway-In 
approach, you can’t effectively rely on your wireless system to tune itself 
automatically because they’ll hear each other more.

We started with an all wireless residence halls concept three years ago and

in-room access points supplemented with APs in common areas. For traditional 
residence halls we went with Cisco 702w initially changing to 1815w access 
points when they became available. For residence halls designed more as a suite

We have 500 Aruba APs for 3000 students in dorm building hallways however we

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Daniel Brisson]

I have found with Cisco’s 1810Ws that we can get more than one room.  
Obviously, this depends greatly on building construction, but we can typically 
get at least 3 rooms covered with one Access Point.  It’s really not that much 
more than deploying the larger APs.  I am looking at between 2-3x number of 
1810Ws to replace our aging 3502i’s, which doesn’t seem that bad really 
considering we just need to add one 48-port POE switch in most cases.

I’ve complained to vendors about this before, but the problem is the 
one-per-room deployment can be 2-4x the cost of in-hall deployment. At smaller 
schools like ours, nebulous future support hours saved won’t make up for 
current costs now.  The biggest issue is an in-hall AP that supports 4-6 rooms 
is only 2x the cost of a single in-room solution. For example, the dilemma I 
face is there is money to replace 6-8 year old APs and I can do one hall or 3-4 
(with no guarantees of future money), which do you choose?

complaints have dropped significantly.  We are an Extreme Networks customer and 
use their AP7502 (http://www.extremenetworks.com/product/wing-ap-7502/) in our

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Jeffrey D. Sessler]

Move to in-room design even if the cost seems problematic. Vendors have never 
recommended in-hallway as a solution (well, maybe with the exception of xirrus 
because of their technology), and all the magic sauce works best when WAPs are 
deployed properly. While a WAP in every-room isn’t a necessity unless dictated 
by construction materials, looking at the crystal ball of WiFi futures, it’s 
pretty clear it’s headed in that direction.

As for the cost, make sure to analyze all factors and not just the cost of the 
WAPs. If you invest in moving to in-room, you’ll likely free up a lot of user 
support/wifi engineering time for other more interesting activities and/or 
avoid/delay staff adds.

Best,
Jeff

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

[Ferguson, Michael]

Unfortunately, we were hit by the same bug as Chad and possibly a few others on 
the list.  It looks like the problem affects Clearpass customers running 
6.6.7+.  We struggled to find a fix early this morning and finally got services 
up around 7:15 am pacific time once we identified the issue.  But until we were 
noticed the problem and resolved it, we were down for wireless access across 
campus for 6 hours due to this Clearpass bug—the issue started at 1 am for us.

This brings up an obvious need on our part to check our Clearpass servers from 
a 3rd-party tool for authentication successes and failures.  I think we’ll have 
to use a Nagios plugin (or something like it) for radius authentication checks, 
which I didn’t expect we would need to do.  As for monitoring other processes 
on individual Clearpass servers, I don’t have a ready answer on that one.

However, this does bring up a desire on my part related to vendor participation 
on the list.  I know we have some HPE/Aruba employees that participate on the 
list and I think the Wireless-LAN group would be a perfect vehicle for them to 
disseminate information to customers that could be affected by known issues, 
particularly ones that could impact services to your campus.

When we had the issue this morning, one of the places I looked was the 
Wireless-LAN discussions to see if anyone was affected by problems with 
Clearpass.  I didn’t see any (until Chad posted later) and so we thought our 
issue was more isolated.  We wasted 20 minutes of valuable MTTR time collecting 
Server Logs when all we needed to do was start the “Policy server” service.  
However, if I had seen a post from HPE/Aruba to the Wireless-LAN list about a 
possible problem affecting many customers, we could’ve started working on the 
real issue earlier.  Putting in a  TAC case related to a critical 1 issue is 
something we generally wait to do if we can’t find a quick fix on our side.

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

So, I am curious how others deal with this.

Do you monitor process status on each of your individual servers?

If so, what methods do you use?

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Brad Weldon]

A few years ago we transitioned from in-hall APs to 1 or 2 in every suite
or 1 for every 2 dorm rooms. Complaints went way down. We based the
decision on RSSI values and that most students were bringing newer hardware
that supported 5 GHz. Much of our roll-out occurred by updating classroom
and admin APs over the course of 3 years and then redeploying replaced APs
into dorm areas.

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Charles Francis]

We went with Cisco 1810w’s in every room over the summer.  The number of calls 
and incidents have dropped dramatically.  The dense deployment has permitted us 
to disable a lot of 2.4, and the 1810w’s permit us to save switch ports in the 
closet.  We also went with Cisco 3802/2802i’s in the common rooms and dialed 
the 2.4 back as well.

Hello all,

We have 500 Aruba APs for 3000 students in dorm building hallways however we 
are getting complaint still even if fine tuning because of walls. I think it is 
very contemporary issue for many.

In every room with Aruba solution would be very expensive. We'd like to ask you 
what is your best solution that you have resolved it?

thanks.

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

[Amel Caldwell]

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?

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

HI fellow Clearpass users:

This one bit us this morning. Not a great way to come into work today.


The Posture and Profile Data update version 1.48743 which was released today 
had caused the Policy Service to crash causing authentication issues.

A defect RM42553 has been created for this issue.

The Dev Team has released an update 1.48751 which has resolved the issue.

Please ensure that the update 1.48751 is installed and the Policy Service is 
running on all the servers in the cluster, by following the below stated steps.

· To install AV/AS Update version 1.48751, Please navigate to ClearPass 
Policy Manager GUI à Administration à Agents and Software Updates àSoftware 
Updates page à Click on 'Check Status Now".

· Please navigate to ClearPass Policy Manager GUI à Administration 
àServer Manager à Server Configuration à Click on the name of the serverà 
Services Control à Check for the status of the Policy server.

· If the status is Stopped, please click on the Start button next to 
it, to start the service.

The ClearPass Dev Team will provide an RCA for this issue shortly.

Re: [WIRELESS-LAN] Best Wireless Solution for Residence Hall Rooms

[Max McGrath]

Umut -

We used to do APs in the hallways years ago, but had similar complaints
that you are receiving.  We've been doing in-room APs for the last 5 years
and the complaints have dropped significantly.  We are an Extreme Networks
customer and use their AP7502 (
http://www.extremenetworks.com/product/wing-ap-7502/) in our residence
halls.  We used to do an AP for every 6 rooms; we now do an AP in about
every other room.  I foresee a day when we have an AP in every room.

Best Wireless Solution for Residence Hall Rooms

[Umut Arus]

Hello all,

We have 500 Aruba APs for 3000 students in dorm building hallways however
we are getting complaint still even if fine tuning because of walls. I
think it is very contemporary issue for many.

In every room with Aruba solution would be very expensive. We'd like to ask
you what is your best solution that you have resolved it?

thanks.

Re: Wireless services in your Stadiums and Arenas

[Eriks Rugelis]

For the Toronto 2015 Pan American Games, AmpThink was retained by the TO2015 
organizing committeee to create the (several) designs for games venue Wi-Fi 
coverage.   One of those venues is on-campus next to the building I am in now.  
At the time, AmpThink's billing rate for engagement seemed to be much more 
reasonable than the number we were given by Cisco Advanced Services.

I have since retained AmpThink for Wi-Fi design of another building (presently 
under construction.)I have no relationship to AmpThink other than as a 
paying customer.

You can find them at:
