Controller and APs upgrade??

Hi
I have a set of APs and I need to buy a controller for them. please see the specification below:
Product/Model Number: AIR-AP1232AG-E-K9
Top Assembly Serial Number: FCZ1032Z022
System Software Filename: c1200-k9w7-tar.123-8.JA2
System Software Version: 12.3(8)JA2
Bootloader Version: 12.3(2)JA4
I am planning to install the 4404 WLAN controller.
do I need to make any upgrade to the software used by the APs?
thank you.

You need two things:
1. You need to prepare the LWAP image to convert your autonomous AP (aAP) to light-weight AP (LWAP); and
2. You need to use the Cisco Upgrade Tool to convert your aAP to LWAP.

Rolling upgrade of WLC 4402 controllers and APs

In need to upgrade the software on two WLC 4402 controller in a hospital. Both WLCs have the same config and one is primary (has all APs connected) and the other backup (no APs connected.) The APs are placed so there is still coverage if one goes down in an area. My question - is it possible to do a rolling upgrade to have no downtime for the wireless clients? My plan would be to upgrade the backup WLC then selectively move APs to it. If I swap the primary and secondary controllers in the high availability tab on each AP, do I need to do a reset (General - Hardware Reset) or will it automatically reboot and connect to the upgraded backup controller? When I'm done, I'd upgrade the primary controller and now call that backup. Does this make sense?

I've done this same sort of thing on a slightly larger scale about 5 times now at the hospital I work at. Quick answer is "Yes, it is possible to do a rolling upgrade and have no downtime for wireless clients."
I've got 5 WLC's, and I use the high availability tab to move all the AP's off one, upgrade it, and move all the AP's from the next WLC over to it, upgrade that one, etc.
The thing you need to be careful of is your timing and your choice of APs to move.
It generally takes about a minute to move an AP between WLCs running the same version. But if there's a version change that makes the AP upgrade, you're looking at about 6 minutes.
I do them one at a time, and when they show up in the WLC as being up, running and happy for 1 minute, I do the next one. And so on. Takes me about 3 days to go through all 5 WLCs and 375 APs. Not once have I had a user notice the move.
Also, in order to test, after I do the first upgrade, I move just one area's APs into that WLC for a day and then test the various flavors of gear we have (phones, infusion pumps, laptops, etc.) to confirm that the new version doesn't have any trouble. Sometimes it does and I work with TAC to get things resolved before I do the whole hospital.

Upgrade WLC and APs

Hi,
We have 3 WLCs (AIR-WLC4402-50-K9) running 6.0.196.0 code.
There are ~55 APs shared among WLC1 and WLC2. WLC3 act as global backup for WLC1 and WLC2.
APs on WLC1 are configured WLC1 as primary and WLC3 as secondary controller.
APs on WLC2 are configured WLC2 as primary and WLC3 as secondary controller.
Since we are planning to deploy few 3502 APs therefore we need to upgrade the WLCs to code 7.x
I was planning the following:
1. upgrade WLC3 first and use the new code as backup image first and the existing one as primary
2. upgrade WLC2 in the same way as WLC3
3. predownload the new code to the APs associated with WLC2 and swap the image to use the existing one as primary and the new one as backup
4. upgrade WLC1 in the same way as WLC3
5. predownload the new code to the APs associated with WLC1 and swap the image to use the existing one as primary and the new one as backup
So far if either the WLC or AP restart for some reason come back with the original image.
6. Change primary image to 7.x on WLC3 and reboot > WLC3 comes up with new image
7. swap image for APs registered with WLC2 and Change primary image on WLC2 to 7.x
8. Reboot APs with WLC2 and WLC2 as well > APs boot up with new image and go to WLC3 if WLC2 is not up yet or back to WLC2 itself
9. Check if APs are on WLC3 if so reboot APs again to go back to WLC2
9. Repeat step 7 for WLC1 > APs boot up with new image and go to WLC3 if WLC1 is not up yet
10. Check if APs are on WLC3 if so reboot APs again to go back to WLC1
Is the above mentioned process sufficient or do somebody know a better/shorter one?
Do anyone have some experience with such excercise?
Thanks,
Krisztian

Hi Ven,
OK thanks for the answer.
However I would need sort of confirmation on the entire process .
Suppose WLC1 and WLC2 are the primary and WLC3 is the backup controller for both WLC1 and WLC2. WLC3 has no APs associted with it.
What I was planning:
1. Load the new code to the backup WLC3 and swap image to use the existing image (6.x) as primary and the new code (7.x) as failover. Reload controller?
2. Move the APs to backup controller WLC3 (in such a way you mentioned) and predownload backup image (7.x) (which is in fact going to be the new code eventually)
3. Upgrade the primary controller WLC1 and use the new code (7.x) as primary image. Reboot controller. WLC1 comes up with new code (7.x).
4. Swap the image on APs to use the new code (7.x) as primary and change the primary controller to the original one WLC1. Reboot APs.
5. Move APs from WLC2 to WLC3 like did for WLC1. APs and WLC3 still runs old code (6.x).
6. Predownload backup code to APs.
7. Do step 3. for WLC2.
8. Do step 4. for WLC2.
9. Swap image on WLC3 to use 7.x as primary and 6.x as failover. Reboot WLC3. WLC3 comes up with new code.
10. Relax have some beer and enjoy
Is the above described the correct way?
Thanks,
Krisztian

Upgrading Controller and AP Help

I'm planning on moving from 4.1.185 to 4.2.130 tomorrow late but am having an issue in testing. My original plan was with 3 4404's and one of them being emtpy, have the 3rd running 4.2.130 and just move AP's from one of the older controllers over to it until it was empty. However that doesn't seem to be working. In WCS, my test AP is registered to Controller 1, I set it's primary to Controller 3 and it doesn't do anything. How can I force AP's over to the controller with the new code so they'll get updated? The reason for this is I can't take down the whole Hospital for a period of time while I upgrade a controller and wait (and hope) all of the AP's come back up over a period of time.

First verify that the mobility groups is confiugred with all the mac and ip address of all 3 WLC's. Make sure you can mping from one controller to antoher. Then what you can do is change the name of the primary controller to that of the new upgraded WLC. Now you can either enable ap fallback on the wlc that the ap is on or reset the ap, so when it boots back up it will try to join the new wlc.

Smartview Addin upgrade and APS

We are on EPM 11.1.2.600 and APS version is 11.1.2.102 as is the Smartview addin. Business is looking at the feature set in later releases of the Smartview addin, specifically Smart Query and some of the VBA extensions of later versions.
We are currently an old Essbase addin shop, with plans to go to Smartview in the near future, so I am not as 'up to speed' on Smartview. My question is if we upgrade to the latest and greatest version of Smartview do I need to upgrade the APS server also? I downloaded 11.1.2.5.x and was able to connect to Essbase and planning without issues but I want to make sure all features/functionality is available. Thanks.

May I know which is your APS server , its recommended to use Web logic for latest version . May be there can be in compatibility if its web sphere !!

Minimum connection speeds 5508 controller and 2602E APs

We have an applicaiton that is sensitive to network speeds. Is there a way to guarantee a minimum wireless network speed such as 100 MBs utilizing a 5508 controller and 2602e APs?

We have an applicaiton that is sensitive to network speeds. Is there a way to guarantee a minimum wireless network speed such as 100 MBs utilizing a 5508 controller and 2602e APs?
Not easy. Wireless is a shared medium. This means if one client talks, everyone else has to stop and wait for their turn.
It's like doing video. Video is time-sensitive. If you put a single AP in a room (granted you've got full 1Gbps ethernet access all the way), and you get 25 people continuously streaming videos, then you'll see some impact. Bring the number down to say, 8 to 10 and you'll see improvements.
What kind of application are we talking about here?

LWAP issues with a 5508 controller after AP upgrade

Hi All, I’m having a few problems after upgrading my AP to a LWAP and hope you can help.
I have an AIR-AP1242AG-E-K9 which had c1240-k9w8-mx.124-21a.JA loaded, I followed the link below and upgraded with Cisco’s upgrade tool to c1240-rcvk9w8-mx with no problems at all, after the upgrade I could then see the LWAP on the 4402 controller and had it working a treat.
Now the problems begin, I brought it into the office where we have 5508 controllers, plug in the LWAP into our management switch and boot it up I get an IP assigned from the DHCP server and the AP goes into discovery mode but never finds the controller.
I have logged the boot process but this does not give much away, our other 1100 series AP’s boot fine, I was hoping that somebody here could help me resolve this issue.

Hi,
If new ap's arent on the same subnet as the controller's management interface, you've got to 'tell' them how initially find the controller.
Dns and dhcp option 43 are the most common methods:

2504 controller + 2602 APs = wireless clients connectivity problems

Hello, everybody!
I have a connectivity problems of wireless clients. The symptoms are:
1) Some clients receive 169.254.x.x., instead a correct DHCP addresses, less in a minute connection drops, and in controller's "Monitor" > "Clients" tab these clients are marked as "Excluded".
2) Most of the clients receive the correct addresses from DHCP (192.168.2.x), but also loose connection soon.
3) Wireless clients with correct addresses can't ping each other, gateway and an address of the controller's dynamic interface (all of them are in same subnet).
4) And the most suspicious problem is that some machines are unable to connect to APs after several attemps to do that. I mean, I configure controller and change some options, trying to understand, whether they were applied or not and constantly connect and disconnet certain PC to the SSID. After five or ten attempts I can't connect to the SSID. During these attempts, the others PCs stay connected, without interruptions, and they could be reconnected again. It's like some kind of port security works, but I'm not sure...
Do you have any ideas which options should I configure?
My configuration:
I have three interfaces on the controller: virtual, management (default) and dynamic (it is set to the WLAN)
I have one SSID, WPA/WPA2, AES/TKIP, authentication PSK.
My clients are a/b/g/n, all are permitted on the controller. No custom security policies were applied.
All the devices are in a single room: controller, one AP and different clients: desktop, notebooks, iPad, Nokia Lumia, etc.
I have an internal DHCP Server on the controller and it works perfectly well.
I can provide all the screenshots required from web-interface of the controller...
Many thanks in advance for all ideas that you have about these problems...

Hi, there!
The problem was solved.
1) APIPA address receives only single machine with Win8 - I think there are some firewall issues
2) Other devices have been loosing connection because they were mobile devices, like iPad and Lumia. If you keep working with it, it doesn't drop the connection
3) The dynamic interface address and gateway address were inaccessible because i had not used an appropriate port on the controller. =)))) Firstly, it was just a guess, but it proved.
Now, everything works with WPA2, AES, PSK...
It is a very good day!)
The only question remains: why I can't connect machines, which have a static IP? During the controller initialization, I said "yes" for permitting static IPs...
Guys, many thanks for your help!

Controller failure - APs still online?

If I have one controller and it fails, will the lightweight APs still be online? Or will my wireless network be down?
I searched and cannot find an answer to this question.
Thanks for your help.

To disable or enable the 802.1X authentication, use this command:
config wlan security 802.1X {enable | disable} wlan-id

2 Cisco WLC 5508 controllers and software upgrade 7.6.130 + FUS 1.9

Hi
I have two WLC 5508 controllers that need 7.6.130 and FUS 1.9 installed. (Current version 7.3 and FUS 1.7)
Configuration: One controller is at Site A and the other controller is at Site B (two different states..)
They're configured so that if Site A goes down, Site A AP's will failover to Site B and vice versa ..
- What would be the recommended approach for upgrading the software to 7.6.130.0 (from 7.3) and also upgrading FUS 1.9 (from 1.7)?
My plan was to download 7.6.130.0 to both controllers and pre-download the software to all AP's (about 100 total between both sites) and then reboot the controllers at night at the same time? Or one before the other?
Step 2. Install FUS 1.9 to each controller.
I'm concerned over what might happen during the upgrade and AP failover etc..
Thanks

This is what I would do:
Upload v7.6.130.0 to all WLCs and then use the pre image download to push the image to all access points.
Dont reboot the wlc
Image swap in the access points so that v7.6.130.0 is primary
Move all access point to one of the WLCs (A)
Enable ap AAA authentication on the WLC that has no access points and the one you will work on first. This prevents access points from joining
Reboot the WLC (A)
Upload the FUS 1.9.0.0
Reboot WLC (A) this takes up to 45 minutes
When the WLC (A) comes back online, uncheck ap AAA authentication
Move access points from WLC (B) to WLC (A)
Enable ap AAA authentication on WLC (B)
Perform all the other task you did earlier on WLC (A)
That's it.

Time mismatch between controller and AP, why?

Hello all,
I have a lab setup with a Cisco vWLC deployed in VMWare ESXI and 2x 1131 APs,
The APs are failing to join the controller due to a certificate error. I have noticed that the time that APs are using is an hour out from the controller.
The controller time and timezone are set correctly (London timezone, it's currently summer time here so its GMT+1), but the APs are being set to an hour early (GMT+0) and are failing to join.
I tried setting the time manually on the APs, but as soon as they talk to the controller it sets itself wrong again!
How can I resolve this?
Thanks
Ben

How can I resolve this?
You can't.
LWAPP/CAPWAP standards do not include the APs to inherit timezones of the controller. So the controller can have different timezones but the controller-based APs are always in UTC/GMT/Zulu timezones.

Wireless controller and Acess points

Hi
which protocal is used between wlc and acess point. and what is CAPWAP.

which protocal is used between wlc and acess point.
It used to be called LWAPP but now it's called CAPWAP.
Access Point Communication Protocols
In controller software release 5.2 or later, Cisco lightweight access points use the IETF standard Control and Provisioning of Wireless Access Points protocol (CAPWAP) to communicate between the controller and other lightweight access points on the network. Controller software releases prior to 5.2 use the Lightweight Access Point Protocol (LWAPP) for these communications.
CAPWAP, which is based on LWAPP, is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. CAPWAP is being implemented in controller software release 5.2 for these reasons:
•To provide an upgrade path from Cisco products that use LWAPP to next-generation Cisco products that use CAPWAP
•To manage RFID readers and similar devices
•To enable controllers to interoperate with third-party access points in the future
LWAPP-enabled access points can discover and join a CAPWAP controller, and conversion to a CAPWAP controller is seamless. For example, the controller discovery process and the firmware downloading process when using CAPWAP are the same as when using LWAPP. The one exception is for Layer 2 deployments, which are not supported by CAPWAP.
You can deploy CAPWAP controllers and LWAPP controllers on the same network. The CAPWAP-enabled software allows access points to join either a controller running CAPWAP or LWAPP. The only exception is the Cisco Aironet 1140 Series Access Point, which supports only CAPWAP and therefore joins only controllers running CAPWAP. For example, an 1130 series access point can join a controller running either CAPWAP or LWAPP whereas an 1140 series access point can join only a controller running CAPWAP.
Guidelines for Using CAPWAP

Help with wireless controller and VLANs

Hi I'm trying to setup a wireless controller in preparation for a large site go live later this year. I'm struggling to get the controller and the WLAN using the correct VLAN. I want the controller on VLAN 100 and the clients on the WLAN on VLAN 200.
My thought is that I would need a config similar to:
Switchport for wireless controller management port set to trunk VLAN 100 and 200 with no native VLAN set.
The management interface on the controller set to VLAN 100.
A dynamic interface created on VLAN 200.
When setup like this I can get to the controller on its management address but only from VLAN100 not from another VLAN on site or from other sites over the WAN.
I have setup a WLAN which is set to use the dynamic interface on VLAN 200.
I have set the AP to use HREAP and set the native VLAN as 200 and added the dynamic interface into the VLAN mappings
When I connecting a client to the WLAN I get an address on VLAN 100.
The switchport for the AP is set to native VLAN 100 and trunk 200 – this setup works for standalone APs at other sites.
What am I missing?
Also any idea why the management interface address is not routing? The netmask and gateway are set correctly.
Thanks
Paul

Just to add to Steve's post... You only need to create a dynamic interface for vlan 200 if you have ap's also in local mode. If your ap's are in H-REAP/FlexConnect mode, you don't need a dynamic interface for vlan 200.
In you H-REAP/FlexConnect ap, you would set the wlan to vlan mapping there and the switchport configuration would be a trunk allowing vlan 100 (im assuming your native vlan for your ap) and vlan 200. You should see something like the following:

5 wireless controller and roaming security

i want to connect 5 wlan controller to core switch with 470 ap . client must roaming and dont have disconnect. what security must configured

Stephen,
I dropped these questions in the Ask the Expert forum, but they are relevant here:
Our intention is to use the Mobility Group to distribute AP connections among many controllers on several campuses for redundancy in the event of catastrophic failure. With this in mind, several questions arise as to how this can be achieved:
1. What is the formula by which an AP, once it has a list of candidate controllers to join, chooses a specific controller? We understand it has something to do with the number of APs and clients a controller is managing, but what are the quantitative criteria/tiebreakers in the AP decision process? What are the relative/absolute values?
2. If we use DHCP Option 43 to point to the APs to a Master Controller, and subsequently re-assign via the controller GUI the APs Primary, Secondary, and Tertiary controllers, will the APs automatically join the Primary, or do they have to be rebooted? And if rebooted, will these WLC assignments override the DHCP Option 43 if not changed?
3. In the above setup, will the AP stop searching for available controllers if the Pri/Sec/Ter WLC assignments fail? Can other, unassigned controllers in the Mobility Group provide a connection for an AP? Or is N + 1 + 1 the limit?
4. Assuming the AP tries them in sequential order, can we place all WLCs in a Mobility Group inside Option 43, or is it limited to 3 entries like the controller-based assignment?
Thanks for any assistance,

Controller and APs upgrade??
