Hi All,

Coming out of a very rough fall semester start that left many of our users 
suffering with "bad" Wi-Fi, we've since (understandably) been asked what 
constitutes "good" Wi-Fi.  We have not previously published information to our 
community on what they should expect or on how they can validate those 
expectations.  Does anyone have any knowledge articles or links they could 
share?

Thanks!
Dave

Just to clarify - is that 17.4.4 or 17.3.4?

Subject: [EXTERNAL][WIRELESS-LAN] rough start of semester on 9800-80 WLCs

Just sending a heads up in case anyone else hits these.  This was our first 
semester with a full campus since moving everything over to our 9800-80 pairs.  
They've been in production for much of the past 12 months and the performance 
was fine when campus was empty.  Under load was another story.

First issue:
Code 17.3.3 has the following bugs that were causing frequent HA failovers that 
reference the wncd process.  This was resolved by upgrading to 17.4.4.
CSCvx37499- Controller reloads with the reason "Critical process wncd fault on 
rp_0_0 (rc=139)
CSCvy20300- Primary controller in HA frequently ends abnormally

Second issue:
Unfortunately these failovers also provoked one of the units to lose the 
contents of its bootflash and get stuck in rommon mode, so we had to recover it 
via the booting to USB routine.  This was also due to a 17.3.3 bug and has been 
hopefully resolved so far by upgrading to 17.4.4.
CSCvy73836- C9800-80 controller goes to rommon after multiple failovers due to 
power cycling

Third issue:
The nastiest thing though was unrelated to bugs.  It was CAPWAP timeouts that 
only occurred in busy areas of campus.  AP uptime would show months, but CAPWAP 
uptimes were constantly resetting to zero.  The logs on the AP would show the 
following message: "Going to restart CAPWAP (reason : data keepalive not 
received)"  We wasted a lot of time troubleshooting this as a connectivity 
issue between our APs and controller, but that wasn't the cause.

This problem was a result of our following Cisco's 9800 best practice 
guide,
 specifically on site tag sizing.  Although the guide says up to 500 APs can 
safely be assigned to a site tag, that was far from the truth in our 
experience.  Several TAC folks missed it and it took our rep escalating the 
issue to a senior wireless design person from Cisco to finally find it.  She 
advised breaking up our site tags so that they didn't exceed 250 APs, which 
instantly resolved the CAPWAP timeouts.


Fourth issue:
Apparently some of the 2702i APs don't handle code upgrades gracefully with the 
9800s.  Cisco made it sound like this was a common issue.  After upgrading from 
17.3.3 to 17.3.4, several 2700s on campus were showing "%CAPWAP-3-ERRORLOG: 
Certificate verification failed!" when attempting to establish CAPWAP with the 
controllers.  This was resolved by manually recovering the APs by pushing an 
image from the downloads page to them via TFTP.  Luckily we have a staff member 
who's pretty skilled at automating this type of stuff.  These were the commands:

SSH to the affected AP
enable
!
(enter password if there is one)
!
debug capwap console cli
!
archive download-sw /overwrite /force-reload tftp://(tftp server 
IP)/ap3g2-k9w8-tar.153-3.JPJ7.tar
!

The AP will automatically reload, establish capwap with the controller, 
download the proper image, reload, and re-join the controller successfully.

Amazon Sidewalk

[Sullivan, Don]

Our Security guy has asked me about Amazon Sidewalk and the possible concerns 
it may present for an enterprise network. I had never heard of it till he 
mentioned it and have started doing some research. It seems to be talking about 
setting up some kind of mesh network though the amazon devices but I am still a 
fuzzy on it. Has anyone else started looking into this and determined whether 
there are concerns, security or otherwise, that might impact our wireless 
networks? Just curious.

Subject: [EXTERNAL]Re: [WIRELESS-LAN] Macbook zoom wireless dropout issues

Zoom starts out trying UDP/8801, then if that fails goes to TCP/8801.  Then if 
that fails it runs SSL on TCP/443.  Then if that fails the user has to use the 
web client over http/https.  You can find the networks needed in an 
automatically updated text list format for linking to dynamic firewall rules at 
the follow URLs:

https://assets.zoom.us/docs/ipranges/ZoomMeetings.txt
https://assets.zoom.us/docs/ipranges/Zoom.txt

That being said, this fallback process is at call setup.  Once the call is up 
and running, if you’re seeing client association issues, then the Zoom 
disconnects or hangs that follow those are just symptoms of whatever is causing 
the wireless issues between the client and the AP.

Ok, I’m going to throw something out there that may sound stupid, but I am ok 
with appearing stupid. When a client initiates a zoom call is that done via UDP 
or TCP? If it is done via UDP, can the session fail over to using TCP SSL 
connectivity in the middle of the call? Can that in turn create a situation 
where the wireless session disassociates and then tries to reassociate? I ask 
these questions because when I have been looking at drops during a Zoom call I 
have been seeing the wireless client disassociating and re associating at the 
same time the Zoom dashboard says the client lost their network connection. 
Those of you using Voyance (ENI) will see it in the time line as a “bad roam”. 
I am wondering if I am seeing a wireless network issue or is it a client and/or 
Zoom issue. I have seen it on both Windows and Macs. Just wondering if this is 
a one off or consistent with what others are seeing.

I was just following this thread along until a ticket dropped in my lap this 
morning with a large Zoom session that apparently was cratering all over the 
place.  After reviewing the connection report from Zoom for the session in 
question, there’s a pretty strong correlation between clients connecting over 
SSL having very absurdly high latency and jitter as opposed to clients 
connecting via UDP.  There were a handful of folks in the session off campus 
and those running SSL had the same problems.

Of course, there were far fewer off campus folks running SSL type connections 
since most home routers let just about anything go outbound.  If this ends up 
being a cause of major issues, then folks switching to hotspots will indeed 
feel like that solved their problems in many cases, causing them to further 
curse the “crappy campus network”. ☹

Zoom uses a fallback to TCP/443 SSL connectivity when it can’t get through on 
its default UDP port (8801) or TCP port (8801).  I’m starting to suspect that 
the SSL fallback might have some significant issues and am going to investigate 
allowing the UDP connections through our firewalls for Zoom sessions.  I’d be 
curious to see if any of the other folks getting big spikes of Zoom complaints 
could provide further corroboration for this theory?

Just curious, did you run the WLAN Poller before upgrade and were there any Aps 
identified having flash corruption issue?

Hello everyone,

We are running code 8.5.135.0 on one of our WLC 8540 pair. We can’t go past 8.5 
because of presence of 3500 and 3600 model Aps which are not supported beyond 
code 8.5.

What code you are running in 8.5 train and how satisfied you are with it?

Is anyone running code 8.5.161.0 recommended by Cisco TAC? How stable is it? 
Have you encountered any major issues in your environment?

Has anyone tried 8.5.16.4 (escalation code)?

Thanks in advance for your responses 

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

[Sullivan, Don]

Ryan,

I used to work for a vendor that built/sold switching, wireless, and telephony 
equipment (not Cisco but a competitor). I was on the post sales side of the 
business working issues through technical support. When we had a situation with 
a customer like you are describing, especially dealing with multiple issues, we 
set up conference calls that included the customer, the account team, and a 
representative from the company’s Technical Support team who owned the trouble 
ticket, plus someone from the group working the bug issues. If necessary we did 
it on multiple days of the week (depending on severity of the issue) so that 
the customer would be able to hear from the guys working the bug(s) as to what 
was going on and how it was being addressed. At a minimum it was once a week 
and every outstanding issue that was being worked was documented and reported 
on. My feeling was that if the customer could hear what was being done to solve 
the issue, it may not alleviate all the frustrations but give them a chance to 
vent to the guys who were knee deep in the code plus add some additional detail 
that could be helpful in solving the issue. I was wondering if Aruba had 
offered you guys anything like. I would think with your university brand and 
influence, they would want to do everything in their power to keep you as a 
customer.

We’ve been an Aruba shop for a very long time and have around 10,000 access 
points.  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

Greetings,

We are upgrading our outdoor wireless APs to Cisco 1562s and want to move the 
mount locations from roof top down to ground level; approx. 10-15 feet up on 
walls.

Unfortunately, we are getting pushback that, aesthetically, this is not going 
to be allowed, even with camouflaging of the AP.

We have now ben tasked with providing photos of outdoor APs in use on other 
campuses.  Thirty minutes on Google showed that this was not an easy thing to 
find, so we are wondering if anyone has photos of outdoor APs on their campus 
buildings that they would be willing to share. Preferably, Cisco 1562s, but 
anything to show that other universities are willing to bend a little on looks 
to gain wireless coverage.

If you have any information on how you handled this dilemma, that would be 
appreciated as well.

Thanks for your time,

Subject: Re: [WIRELESS-LAN] Helpdesk Troubleshooting of Wireless Issues

Our WiFi complaints fall into a couple categories:

1.  I can't connect this device.
  - For this, the helpdesk will take the user through the steps to connect the 
device, at a walk-in location, over the phone, or via email/helpdesk software.  
For stubborn devices, the support folks will create a ticket and kick it over 
to one of our 3 Network Analysts (which includes me).  Our network analyst 
position is basically admin/engineer/all network support escalations.  We have 
access to all the tools provided by our vendors to do deep troubleshooting as 
to why a connection is failing.  In a few instances, if we are burning too much 
time on a problem that is clearly a client issue, we will send it back to 
desktop support.  This was the case with a Dell XPS that needed a BIOS update 
to connect to our .1x network.

2.  There is no coverage in this spot.
- One of the network analysts will go to the spot and survey the signal.  
For any trip to a residential building, we go in 2's to protect ourselves from 
false allegations of misconduct.  We don't have full spectrum analysis tools, 
but we can at least check for signal level, and rogues, look around for 
microwaves or other obvious sources of interference.

We don't have any specially trained helpdesk techs.  Before they escalate a 
ticket to us, they are generally pretty good about gathering basic info - 
username, location, ideally the MAC address of the client device so we can look 
it up in AirWave and our NAC system.

Same as Jason's earlier post, communication is handled by whoever is actively 
working the ticket.

online testing using the wireless network

[Sullivan, Don]

I was curious to see how other schools are handling online testing over the 
wireless network. I wanted to see if policies or procedures have been put in 
place to minimize wireless issues that may occur while testing is taking place. 
In our situation, online testing started several years ago where it was limited 
to only a couple of classrooms. It has since expanded significantly. Our 
experience has shown that the testing methodology used can have an impact on 
the issues reported, what type of device you are using (MAC or Windows), and/or 
the browsers that are used (usually customized to avoid cheating. An example – 
the customized browser used on the MAC will not allow you to go back to the 
previous page, but the Windows version will. If they drop their connection, 
this causes a problem for the MAC users and they have to start over).
One specific policy I was wondering about pushing, and whether anyone else had 
considered it or was using it, was to stipulate that all wireless devices not 
being used for the test have their wireless turned off. If there was an issue 
every time they took a test because of the number of devices attached to the 
AP, that would be easy to say it needs to be done. But that has not necessarily 
been the case. We can go through several tests with no issue then have 
something like 6 users out of 40 experiencing issues.

Because the testing methodologies are different between the departments (I am 
aware of about 3 different methods of online testing), setting policies across 
the board doesn’t necessarily fit. So I just wanted to see how others are 
handling this in their networks. Thanks.

Lee beat me to the punch. We are using Voyance by Nyansa to look at client 
performance and overall wireless performance. We have done surveys in the past 
and, like everybody else, you find that any network issue is essentially a 
wireless issue so you do not get any specifics in my mind to make any 
significant difference. Voyance is a big help, in use with my other tools, in 
narrowing down problem locations and giving me a better idea of the overall 
client performance. Plus it helps to know how we stack up against similar

Your best source of information is the management platform that is monitoring 
your wireless. For example, if you are a Cisco customer, you have an endless 
amount of data in which to judge performance and coverage along with a lot of 
other items such as average connection rates, avg RSSI/SNR, % of clients at 
what rates.

Surveys can be effective if they are well done. If you have an office of 
institutional research, it’s best to work with them on the questions, ensuring 
that you get relevant and useful data back e.g. Have the student pick the 
residence hall they are in, then ask specific questions about their experience, 
then classrooms, public places, etc. Offering incentives can help too in that 
you get people how are both happy and unhappy. To be useful over time, the 
questions shouldn’t change year-to-year.

Besides a survey, your students are likely participating in various 
college-related social-media groups. I have my student interns monitor these 
groups and report back chatter related to wireless.

Subject: [WIRELESS-LAN] 5GHz Channel Width

Hi All,

I was just reading a blog article that heavily recommends not to use 40Mhz 
channel width in multi-floor environments, particularly where many 5GHz radios 
are used (particularly in our case with Xirrus multi-radio APs). Our campus 
presently uses 20MHz channel width in all buildings. We are testing and 
considering 40MHz width because of the bandwidth benefits for clients. What do 
you use on your campus? Have you found that setting a 40MHz channel width on 
your 5GHz radios has caused too much interference?

Here is the article:

Your thoughts are appreciated.

RE: Question about Cisco 1810w APs in residential buildings

[Sullivan, Don]

Our experience is in line with this statement. We use the Cisco 702 APs and 
have found when they do get knocked off of the wall the APs do not suffer any 
damage. I have seen a couple of messed up mounting brackets but the APs 
themselves were still working just fine. This has occurred about 4 or 5 times 
over the last 2 and ½ years. We have around 700 of these APs deployed in the 
dorms.

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?

They are designed to cover the room itself.  Rollins has found that it does do

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

Airplay peer-to-peer

[Sullivan, Don]

We have started using this year the Solstice Pod by Mersive in a number of 
classrooms. It seems to be a pretty nice product but since school has started I 
have gotten complaints about losing connection while in the middle of a 
presentation. The Pod is hardwired into the network and the clients are on 
wireless. Because of this the first thing to blame obviously is the wireless 
network. In my investigation it has become apparent that the process a majority 
of users are using is to initiate a session through the Solstice client and 
then use Airplay to mirror to the Pod. This is being done through Airplay 
peer-to-peer. Through previous discussion on this list and Cisco documentation, 
I am trying to determine how this interacts with our wireless implementation, 
is this a wireless issue, and if so, what are best practices for handling it. 
Based on what I have read, there are recommendations on turning off channels 
149 and 153 because Airplay PTP is using channel 149. My thoughts were to turn 
off these two channels and turn on channels 120, 124, and 128 which are not 
currently enabled. Before doing this, I thought I would run this by you guys 
and see if anyone else has dealt with something like this and if there were any 
gotchas with disabling these channels and enabling the others. I would 
appreciate any feedback you might have to offer. Thanks.

Anybody using Ridesystems GPS app?

[Sullivan, Don]

We are looking at using Ridesystems GPS app for our shuttle service. The riders 
will access the app while they are on the shuttle bus. Apparently there is an 
issue because they are riding along the edge of our wi-fi service out of our 
buildings where the phones pick up the wi-fi but not enough to get good service 
and their phones do not switch to the wireless provider so the app gets hung 
up. Has anybody else run into this issue with their shuttle service and, if so,

Subject: Re: [WIRELESS-LAN] How big are your wireless segments?

One thing to remember is that over the air you have the same amount of 
broadcast whether it is one vlan or a pool of 4.
For Example: If you have 4 client segments that are a /24, and each AP has a 
client on one of the 4 subnets, you still send the sum of 4x /24 network 
broadcast over the air.  Meaning only on lightly loaded APs where you don't 
have all 4 subuets do you get a net gain of airtime.  Same applies for 
link-local multicast.  Smaller subnets in pools don't really gain you much 
without the suppression techniques, and with the suppression techniques, you 
don't need the smaller subnets.
The place where pools/groups of vlans are attractive is where you may be using 
public IPs and don't have a large contiguous block of IPs in which to place 
clients.  So picking 4 non-contiguous /24 networks is easier to do than picking 
a full class B.

Brian,
  We have pools of /22 /23/ and /24.  We separate our pools from students vs

Aruba does a lot to prevent broadcast storms, but I feared the overhead of one 
large segment might have on it.   We also give students a different ip pool 
depending whether they are in a residential building vs an academic/admin 
building.  This allows us to shape traffic differently.  But this will become 
less of an issue as we acquire more bandwidth (hopefully).
   I am curious of those using /16, does that resolve your layer 2 issues?   
Aruba does a good job of bridging many layer 2 solutions anyways, but having 
one /16 vlan does seem enticing and perhaps unnecessary for bridging protocols. 
 However, I am curious about other overhead efficiency issues.

If folks will send me information on their wireless networks I will tabulate it

Brand(s) of APs in use and approximate number of APs for each brand
Whether the APs are standalone or controller based
Wireless management platform (e.g., Cisco Prime, HP Aruba Airwave, none, etc.)


For the University of Alabama I would answer as follows:

The University of Alabama
45,000 clients
Cisco 5,000 APs
Controller based
HP Aruba Airwave management


If others want to suggest additional questions, that is fine as long as we can 
get them soon enough so that most people who respond will have answers to all 
of the questions. Why don't we collect questions until next WED and try to get 
the poll sent out next THU?

wireless access points in addition to the emergency phones already required. To 
that point I wonder if it will eventually become part of the local building 
codes.

Hi Don-

I agree on the costs. I'm thinking opportunistically, like where a major 
re-work or new building might be in work versus retrofit. There's a lot of 
technical and philosophical points to be considered, for sure.

Lee,

Our thoughts and planning on this subject started about the time I read your 
email.  :)

I have not given any thought to this before but your email has raised questions 
as to what we might need to consider going forward. Considering how we would 
implement something like this in our current buildings/facilities would be a 
challenge and a potentially costly one.

Subject: [WIRELESS-LAN] Purpose-Built Wireless Coverage in Stairwells and 
Elevators

Hello to the excellent group.

As you get into new building wireless deployments, I'm wondering if anyone is 
rethinking their coverage of elevators (like with dedicated coverage in each 
car) and stairwells (also specific coverage, not just bleed out from hallways) 
now that we're into the era of Wi-FI calling, RTLS, safety apps, etc.

Granted, if you have an established VoWiFi culture, the question may seem 
low-brow, for the rest of us I'd love to hear your thoughts on what you are 
doing with WLAN in stairwells and elevators, what you're planning on doing 
differently from what you've done in the past (if anything), whys and why-nots, 
and general thoughts on the topic.

Thanks-

We are running an 8510 also. We have not seen any catastrophic issues on

For those on high-capacity 85xx controllers and using the likes of web

RE: troubleshooting wireless issues

[Sullivan, Don]

That's a really good question. It sounds like we are in the same predicament as 
your school. Like you, we tend to be more reactive when we observe issues with 
wireless ourselves (APs disassociating, etc.) or someone taking the time to 
report an issue (we are even monitoring twitter for complaints).  If someone 
has a magic bullet, I sure would be interested in hearing about it.

I'd like to know what other schools are doing to proactively troubleshoot 
wireless issues on your campus.

Our network team does a great job of troubleshooting end user wireless 
connectivity issues when a customer calls the Service Desk to report an issue, 
but end users don't like to call our Service Desk to report issues.  Because of 
this, end users assume our network sucks or they try their own workarounds (eg. 
using cellular data, etc.).

What level of success do you have with customers contacting your Service Desk 
about connectivity issues?  Do you do anything to proactively find out if 
customers are having connectivity issues?

It seems like a lot of the issues are on the client side (eg. updating Surface 
Pro drivers, applying a Mac fix, etc.).  What approaches are you using to 
communicate about device specific issues?

I'd appreciate any feedback you have on how you are approaching this issue on 
your campus to improve end user experience with your wireless network.

Thanks,
Dave

RE: Cisco 702W APs

[Sullivan, Don]

The 4 data ports on the 702 are configured down by default. We are on 7.6.130.0 
and that means you must enable each port manually through the CLI of the WLC to 
make them active. Supposedly, you will be able to enter a range in 8.x. The 
other issue we saw is with the POE data port. We tested running a phone off of 
the 702 and it would not stay up. Found this bug 
(https://tools.cisco.com/bugsearch/bug/CSCup78439/?referring_site=bugquickviewclick).
 The workaround till it is fixed is to turn off CDP on the phone. We deployed 
around 700 of them and it has really helped in cutting down the wireless 
complaints in the dorms.

Sorry, forgot to mention the issue about the NAC vendor needing to support 
changing VLANs on the AP. We have been told this will be coming out later this 
year. Our deployment plan was based on the dorm’s construction. Where possible 
we did one in every other room, but we had 4 dorms where we put one in every 
room. We have not lost any so far to being damaged, but we still have students 
plugging in wireless routers for devices that cannot authenticate into our 
primary SSID. In those instances we have seen an AP go down and when we check 
it there is a router plugged in. We detach the router, power cycle the AP, and 
it comes back up. We have not done a detailed investigation on that particular 
issue to see what may be causing that. Just have not had time.

Hello William,

Did you have to install the 8510s into a two post rack?

One solution we deployed for a similar issue was to deploy a 2 post to 4 post 
conversion kit.   This required that we place a second rack a couple of feet 
behind the original rack and then installed the conversion kit parts to join 
the two racks together as one unit.  We could then co-locate the handful of 4 
post devices in the same rack as the 2 post network equipment.

One vendor of this type of 2 port to 4 post conversion kit is Kendall Howard.  
We used their  4-Piece Rack Conversion Kit SKU: 1927-3-004-00

Apple TV issue we are seeing

[Sullivan, Don]

I was wondering if anyone else has run into this before with Apple TVs. We are 
still running Cisco 4400s as our controllers and are on 7.0.235.3. The Apple 
TVs that are on the wireless network are getting this alarm:
Client 'xx:xx:xx:xx:xx:x (xx.xx.xx.xx)' which was associated with interface 
'802.11a' of AP 'Haywood-BB-2' is excluded. The reason code is '3(Attempted to 
use IP Address assigned to another device)'.

We have checked and there are not any duplicate IPs. We have tried assigning a 
static IP but it continues to get this alarm/event. I did a web search and 
found something similar where it indicated disabling the exclusion policy IP 
Theft or Reuse would be a work-around. I tried this and it did resolve the 
issue, but I am not comfortable with this being disabled as I do not fully 
understand at this point what this policy fully covers other than duplicate 
IPs. I am curious if anyone else has seen this problem and what steps they took 
to resolve it.

We've been approached by wireless company to install a DAS (distributed antenna

Subject: [WIRELESS-LAN] Windows 8 and Broadcom wireless cards

Good morning,

I was wondering if any other school is having issues with the Broadcom Wireless 
network cards running Windows 8/8.1 pro on a WPA2/AES network?  We have 
students that are upgrading their Dell computers from Windows 7 to Windows 8 
and the cards stop working on our secure network.

They are prompted for 802.1x credentials, and the ACS server authenticates them 
as well as the DHCP server handing out an IP address, but the computer always 
states limited or no connectivity.

What is really weird is that we have a 1232AG radio and the card will connect 
ONLY to the A radio, but not to the 1142N-A radio.   We are running 7.0.253.5 
code because of the older AP's on campus.   We did purchase a separate 
controller for a test environment which we have running 7.4.110.0 now and it 
still won't connect to the 1142n-a radios.

Trying to back the driver down to Windows 7-64 bit doesn't work (won't allow it 
to be installed).

Any ideas?

Thanks
Shayne

Aerohive wireless solution

[Sullivan, Don]

I wanted to see if there is anyone who has implemented a campus wide Aerohive 
solution and would be willing to answer some questions and discuss offline how 
well the solution has worked for them. We are planning on upgrading our current 
wireless solution, but before we dive in I wanted to check into alternatives.  
Thanks.

 In response to my question yesterday, a Cisco engineer who is
 heavily
 involved in RRM sent me information in response to my question
 which has
 been very helpful to me in understanding what is occurring and
 whether I
 should be making any changes based on what I am observing. If
 you would like
 for me to forward this information to you please let me know and
 I will be
 happy to. I will tell you that he confirmed what one person had
 stated in
 one of the earlier emails that at code above release 6 there is
 no good
 reason to change the default interval.

 There was a post on Cisco support forum about DCA interval and
 some senior
 contributors (not Cisco guys though) suggested to set it to 24
 hours. I
 tried to search for it now but could not find it. We did have
 the AP channel
 change issues which affected about 50 APs at once. We thought
 the default 10
 minutes interval is too aggressive and 24 hours is too long. We
 started with
 1 hour to see how it went and we haven't had any issues.

 Can I ask what led to making this change? I am struggling trying to
 understand moving from a default of 10 minutes to 24 hours and
 the impact. I
 have been reading the documentation and reference for this
 setting in trying
 to determine if this is something I should implement but there
 is very
 little detail concerning the timer/interval. Based on the
 replies, 24 hours
 seems to be the choice and yet I cannot find through a google
 search why
 this is better. Appreciate any feedback given.

 Thanks,

A long time ago I increased the interval for this up to a pretty high setting 
from the default (I think it was 10 min) at the suggestion of TAC engineer to 
stop them from changing channels so frequently.

802.11x  RRM  Dynamic Channel Assignment (DCA)

I have no evidence that there is any issue with it, but a lot has changed since 
then.  What intervals do others use for DCA?

Questions about WCS error

[Sullivan, Don]

Concerning this error -  The AP '??' received a WPA MIC error on protocol '0' 
from Station '68:a8:6d:3c:63:dc'. Counter measures have been activated and 
traffic has been suspended for 60 seconds. -   Whats the general take about 
disabling the Client Exclusion feature in WCS? I do not have TKIP enabled on 
our WLANs and my reading on this feature seems to indicate it has to do with 
TKIP.  Thanks for the feedback
