Cisco WLC 5508 software recommendations

[Entwistle, Bruce]

We are looking to upgrade our pair of 5508 controllers from the current 
version, 8.5.151.0.  We cannot move beyond the 8.5 code as we are still using 
some older 3500 access points. I have seen many comments regarding versions of 
code to avoid, but was looking to see what versions the group has found to be 
stable and would recommend moving to.



Thank you

Weak Security

[Entwistle, Bruce]

Apple devices that are updating to IOS 14 are now reporting that wireless 
security is weak.   We are currently using a combination of WPA/TKIP and 
WPA2/AES for security, but are considering the move to WPA2/AES only.  I was 
looking to see what others have done and what challenges you faced in making 
these changes.

Hi everyone,

I was wondering how you're managing actually joining Sonos products to your 
network. If you've had the pleasure of setting some of these up you may know 
why I need to ask.

They don't really like to individually be directed to join a network and they 
don't really have a UI that just lets you log in a manage a units network 
connection.

The best I've come up with is a kind of convoluted process that requires 
setting them up wired first and then directing the set you want to manage with 
a given (newly required) user account to join the network at the same time.

I think there's also differences between product lines. So far my experience is 
with Play:1's, Play:5's, and Connects which our process works with.

Thanks,

Last year we converted our first residence hall to wireless only and there were

RE: Offline/Spare Gear Inventory Size

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

Hi All,

I’m curious to know the size of your spare gear inventories. Do you keep a 
percentage of each model of AP in inventory, and what is your reasoning? 
Storms? Last minute/emergency wireless coverage needs?

What percentage of your live gear do you keep as offline inventory? (100 live 
APs with 1 inventory AP = 1% offline inventory).

With Xirrus, we had an offline inventory of more than 10% of live inventory. We 
kept that inventory to cover the high failure rate of the equipment, the 
incidence of hurricanes and lightning strikes in our area, the broad range of 
AP models on campus, and last minute large events in low coverage areas.

We are evaluating the minimum offline inventory for our new Aruba gear as we 
finish up the vendor switch. I have been thinking 1-2%, but I want to see what 
you guys do first, and why.

Thank you,

RE: [WIRELESS-LAN] Another Cisco WLC Code Thread

Happy Holidays,

Like many others I'm sure, I've been studying all of the email threads from 
this list to see if anyone has settled on any of the current code releases on 
their controllers. With all of the bugs disabling several AP models, we have 
been holding off our code upgrade and wireless migration.

I have a plan to move about half of our wireless APs off of a pair of WiSM2s to 
our new 8540's next week. We've had the 8540's up since the summer running on 
8.4.100.0 seemingly without many issues. It's been pretty stable but there has 
only been about 80 APs on it for our Fall semester. That code release is now 
deferred and we've looked at going up to 8.5.110.0 which released just a few 
days ago. Release notes list the open caveats, and there are several that still 
impact the 3500/3600/3700 lines pretty hard. 8.6.101.0 released a day after, 
and its even more grim.

Has anyone found anything stable? We have a pretty wide deployment of APs, but 
most of them are 3500/3600/3700s with a fleet of 702W/1810W in residences. We 
simply don't have the manpower to run around and console into APs that lose 
their marbles, and our time slot to move forward is narrowing by the day.

And more importantly, I would like to sleep better over the holidays, like we 
all would I'm sure.

Thanks for the input,
Britton

Here's ours:

2 8540s in HA mode (bought with the idea of replacing all WiSM2s)
4 pairs of WiSM2s in HA mode
3 server ClearPass cluster for both eduroam and guest
Main SSID: eduroam with PEAP/MSCHAP
Mix of WAPs; 3500, 3600, 3700, 2800, 1810w
Total number of WAPs: 3500
21000 peak users

We tested the 8540s extensively over the spring and summer, primarily with the 
8.2.151 code and a mix of 2800s and 1810ws. We had AVC turned on, and were 
using RLANs for the wired ports. The largest number of WAPs we had on this pair 
was 469. We tested code 8.2.160 towards the end of the summer with all WAPs on 
the 8540s, and had no issues. First the day of classes, we had all WiSM2s 
running 8.2.160 simply as a backup. Early morning we started getting reports of 
802.1X authentication failures (these failures had nothing to do with 
ClearPass). Shortly after that, WAPs starting flapping (disconnecting from the 
8540s moving to WiSM2s and then moving back again). We tried playing with the 
TCP MSS setting, adjusting EAP timers, turning AVC off and multiple other 
things, but nothing worked. In the end, we downgraded the WiSM2s to 8.0.140 and 
moved all WAPs that were not 2800 or 1810s. The 8540s were downgraded to 
8.2.151 so the 2800s and 1810s would have a controller to connect to. Network 
stability was restored after this.

Needless to say it was a very unpleasant experience. We are still working with 
Cisco to find out the root cause of the problem.

It might be beneficial to share notes in case other schools are hitting common 
problems. I'm wondering how everyone who is in the thick of it is faring with 
back-to-school?

On this end, we are doing OK halfway to our expected total daily peak clients 
(we're at 15K now high water mark).

Our significant WLAN-related changes since end of Spring semester
* Running 8.2.151 on our 8540s
* Significant quantities of Wave 2 APs
* ISE as RADIUS (only, no NAC, no onboarding)

No changes to:
* our guest WLAN (Clearpass/an Aruba controller pair)
* onboarding (Cloudpath Wiz)
* overall topology
* open network in dorms for gadgets
* non-use of AVC, it crapped out and never got solved after hundreds of 
hours with TAC

Fears:
* We haven't yet hit the scale that will reveal problems with any of 
the newer stuff listed above

Anyone else care to share?

Short answer is it is a bug.  A "Kernel Panic".  AP loses its mind.Very 
prevalent on the new stuff, to a much lesser degree affects "older" stuff.

Sometimes the reset fixes it.  Sometimes not.  We doubled down on 1810's and 
2802's.  Bugs galore.  Which are actively being fixed-to be fair.

We are running on engineering code and HUGE improvements have been made. Soon, 
I think/hope, it will be rock solid.

3600, 2700 and 3700 APs.

The only issue I have seen that I don't understand well yet is related to some 
APs losing the minds during network interruptions. The APs will appear up from 
CDP neighbor information, but will have lost their name and will not connect to 
their configured primary or secondary controllers. A power cycle will often 
recover the AP, but not always. I believe that issue started with 8.2.

RE: Disabling LEDs on APs

[Entwistle, Bruce]

After going through several rooms and finding tape, post-it notes and other 
similar things on the APs covering the LEDs we went ahead and disabled the LEDs 
on all residence hall APs.  No problems, except for the occasional time you 
forget where you are and look up and think the AP is down because there is no 
LED indicator.

Subject: [WIRELESS-LAN] Disabling LEDs on APs

First-world problems... Curious if others have gone down this road in Residence 
Halls. We're not really being asked to, but are considering wholesale disabling 
LEDs on our Cisco APs in the dorms as a quality of life step. Has this caused 
anyone any pain when it comes to not being able to see the colors on the AP as 
status indication? Have you actually had requests to disable the LEDs? Overall 
experience with accommodating or denying the request?

Thanks-

RE: [WIRELESS-LAN] Cisco interface groups

[Entwistle, Bruce]

We have used interface groups since the initial installation of our 5508 
controllers and they have worked well.  One issue we did have was an older 
application required clients to be on the same subnet and would fail when 
clients were distributed across the VLANs in the interface group.

We are in the process of moving from a controllerless vendor to Aruba.  Our 
current design is very segmented, to keep wireless device broadcasts from 
overwhelming the network and AP's (we had this problem back in 11g days).  
Presently, we've limited segments to /23's (give or take).  In your 
controller-based environments, how large have you let these segments go?  Is a 
/21, /20 ... viable?

As our campus rapidly changes and grows, we began placing office spaces in our

area that has a fixed connection back to our main campus. Networking within the 
same building was simple as we did this during the renovation.

With our growth, the administration is now planning on throwing together 
another Ad Hoc office space in a separate building. This building is relatively 
close to our main office space (+-50 feet), however we have no cabling between 
buildings and no conduits in place.  I'm interested in testing out a low 
latency line of site wireless bridge, one that I could utilize to distribute to 
multiple buildings as our growth continues, across up to 1000 feet and from 
100-1000mbps speeds.

Can you share what vendors you've had success with? Engenius, Ubiquiti, etc., 
come to mind initially.

I came from the corporate world a couple of years ago, and there is a similar 
need in business. We sometimes just had to say “no” because sometimes just a 
temp/quick thing violates policy that may be tied to law (security policies 
related to Sarbanes Oxley, for example). Or, depending on who you asked, you 
went out of your way to set up a laptop with the printer directly connected and 
acting as a temporary print server (not proud of it, but when a CxO asks, you 
jump).

If this was a common need in business, then I would expect someone like HP to 
build it in. I suspect however, that this is one of those edge-cases where 
EDU's act differently than business, but use business features with 1.x.

On your open network, couldn't you use Cisco's built-in device profiling/policy 
classification to drop it into a different vlan (no need for radius) and avoid 
routing tricks? You could drop it into the same network as .1x.

Again, if this is just a temp/quick thing - popping up a PSK WLAN on a couple 
of AP's using an AP Group (in Cisco terms) is two minutes of work. Far less 
time then trying to convince HP (or others) to add .1x support.

Lee,

I'm curious about the need to be on 1.x. Is there something compelling that 
can't be accomplished using PSK, or even an open network that 1.x can? If the 
printer supports IPPS or other SSL/TLS encrypted communication channel, then 
does 1.x matter especially in a temp/quick situation?

Just my quick thought would be to drop it into a open, wep, or psk, and if 
required, use device profiling/policy classification to drop into desired VLAN.

If the cost of an outlet was more than the cost of a decent printer it'd be an

Can print / can't print cost difference of $100. Value add of same?

If you look at a graph of our Internet traffic versus Akamai server traffic

 For those of you impacted by such things, have you considered asking

 Akamai to install a local caching appliance on your campus? We did a

 number of years ago, it was free, and greatly reduces the impact on

 our commodity internet while boosting update speeds significantly.



 I know Apple is starting to roll out their own CDN, but for now, there

 are a lot of companies besides Apple using Akamai, so it's worth it.



 We also just established free direct peering with Netflix. Big

My question is coming from the code side- has anyone been through this sort of 
condition on Cisco AP/controllers on or near this 7.6.110 code version?

APs get good DHCP, find controller, settle in, start serving clients.
Randomly and frequently, AP will either jump to another controller or fall off 
totally and eventually reboot.
Condition repeats.

Just looking for ideas from code side, if it’s ringing any bells.

Gaming consoles/streaming devices

[Entwistle, Bruce]

I know this topic has been discussed before but the start of the new school 
year has restarted our conversation on this topic.  What I am referring to is 
what schools are doing to accommodate students in connecting their 
entertainment devices (game consoles, media streaming players, etc) to the 
campus wireless network along with managing the traffic associated with these 
devices.  We are considering different options for authentication; periodically 
changed static key, MAC address registration, along with using our PacketShaper 
to manage the traffic, but are looking to see what other campuses have done and 
the challenges they encountered.

Apple produccts in a multi-vendor environment

[Entwistle, Bruce]

We are currently installing some Aruba APs on our campus which has been fully 
covered by a Cisco wireless network.   Both systems are controller based 
installations, Cisco 5508 Aruba 7210, and both authenticate users against our 
Cisco ACS server.   Both wireless systems are broadcasting the same SSSIDs to 
provide a common experience for the users.  We have run into a situation where 
all devices connect to both networks without user intervention, except for 
Apple devices, which request the users accept the certificate from our ACS 
server.  We have run tests using the same device and user ID on both network, 
but each time the apple device connects to the Aruba network the user is 
prompted to accept the certificate.  We are trying to install the second system 
without having the users notice any changes.   Has anyone had a similar 
experience they are willing to share.

RE: [WIRELESS-LAN] Multi vendor interoperability on Campus

We are currently in the process of installing a second vendors wireless 
hardware on campus, current Cisco installing Aruba, using the same SSID on all 
APs.   Both systems authenticate against the same ACS server.  In our pilot 
deployment, windows PCs seemed to connected to either network with no

What are others doing to get interoperability when you have multiple wireless 
vendors on campus?  We are transitioning to a new system and trying to think of 
all the issues we may run into during this.

A little background about our layout… a building will have all the same vendor 
AP's but adjacent building may not, over 100 buildings on campus,  total of 
4000+ across campus, systems will have different ip pool space, and limited 
outdoor coverage.

Ideas
1. Same ssid across both systems and let the clients choose what system.
2. Same  ssid and adjust the probe/reponse thresholds so clients outside of a 
building don't connect.
3. Have versions of ssids for each system so clients can choose what ssid to 
connect to.


Thanks,
Jason

RE: [WIRELESS-LAN] Wireless in Residence Halls

[Entwistle, Bruce]

We installed our APs in the hallways, and found that the APs were seeing such a 
strong signal from each other that the Cisco controller would power down the 
signal strength for the APs.  This was causing a impact on coverage in the 
rooms along the hallway.

Off-net Rogue APs

[Entwistle, Bruce]

I know there have been multiple discussions regarding how schools deal with 
rogue APs connected to the campus network.  However we have run into a 
different situation and I was wondering how other campuses are dealing with 
this.  We have students who are purchasing their own internet service to their 
room through the local cable company, then installing their own AP on this 
network.  While this does not carry the normal concerns associated with rogue 
APs there is the concern about the wireless interference created.  I am curious 
to know what policies/procedures others have used to deal with this situation.

Wireless design

[Entwistle, Bruce]

We will soon be migrating our wireless network from Cisco autonomous 1231 APs 
to a combination of Cisco 3502i along with some of the existing 1231 APs 
converted to lightweight.   As we prepare for this we are looking at how to 
best architect the new network.The new network will cover the entire campus 
which consists of approx 50 buildings, with each building having its' own VLAN.

The initial idea was to install the APs so the IP address of the AP would be a 
part of the local building VLAN.  This is the IP the AP would use to talk back 
to the controller.  For user connections there would be two VLANs created which 
would be accessed through a single SSID.  The users would then be dynamically 
assigned to one of the two VLANs based on their logon credentials.  Currently 
all users are placed on the same VLAN after authentication, as our current 
installation is not capable of dynamic VLAN assignment.  There is currently 
only a single SSID in place.

I would be interested to know what other have done and how successful it was.

Crew,
We hide our access points above ceiling grids. Our logic is the devices are out 
of site and less prone to vandalism (in fact we have had zero vandalism).
One concern that has been expressed by our wireless team is the congestion 
above the ceiling grid - pipes, HVAC ducting, lighting and cables. It is 
logical that all of these obstructions do not help RF propagation and create 
sources of interference.

My question for you guys:
Did any of you change your mounting locations from above ceiling grid to below 
the grid (visible)?
Did you notice substantial signal improvement?
What is the vandalism rate?
Did your facilities/administrative folks express any concerns 
about the AP visibility?
