Upgrading a WLC 4402-25 to 4402-50

Hi
Does anybody know is there is a software release to increase the 4402 from 25 to 50 AP's

Hi Fenton,
You won't love this answer but, the number of supported AP's on a WLC is based on the Hardware configuration and cannot be changed. You will need to purchase a second WLC. The upside is you will be able to add some redundancy to your deployment :)
\\The limitation on the number of supported access points is based on the hardware that you have. The 4402 WLC with two gigabit Ethernet ports comes in configurations that support 12, 25, and 50 access points. The 4404 WLC with four gigabit Ethernet ports supports 100 access points.

  • Upgrading from WLC 4402-50 to WLC 5508-250

    I am planning to upgrade my WLC 4402-50 (HA) to WLC 5508-250 (HA). I also have some really old 1020 Access points that I will be replacing with 1142's. Once I have completed the upgrade to the 5508s, I will repurpose the 4402's as Mobile Anchor controllers to support Guest Wireless.
    Does anyone have any actual experience with this sort of upgrade? Any practical suggestions or ideas??
    Thanks,

  • 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.

    Hi,
    Go for 7.0.250.0(It is the last supoort version for this WLC). You can directly upgarde from 6.0.199.0 to 7.0.250.0.
    http://software.cisco.com/download/release.html?mdfid=279911193&flowid=7586&softwareid=280926587&release=7.0.250.0&relind=AVAILABLE&rellifecycle=ED&reltype=latest
    And 1242 AP supported this software.

  • Problem to register upgraded AP 1242 to WLC 4402

    Hi,
    I am running a small Cisco WLAN with about 20 APs (all 1242) that are managed by two WLC 4402 (running v4.0.155.0).
    WLCs are in Mobility group, serveral WLANs/VLANs are configured (including 802.1x, guest access with WebAuthentication etc.). All APs are configured for the same WLC as primary and the other as secondary. Everthing was working fine until I tried to upgrade another AP from IOS to LWAPP using the Cisco Upgrade tool.
    After the AP was flashed and rebooted it started to discover a WLC but fails. The console messages look like this:
    *Mar 1 00:00:05.962: %CDP_PD-4-POWER_OK: Full power - AC_ADAPTOR inline power source
    *Mar 1 00:00:06.952: %LINK-3-UPDOWN: Interface FastEthernet0, changed state to up

    *Mar 1 00:00:54.398: %LWAPP-5-CHANGED: LWAPP changed state to DOWN
    The switchport of the AP is configured for the same VLAN as the management and ap-management interface of the controller (not native VLAN), the primary controller is set to master controller mode and I see no other error messages (e. g. on the WLC).
    Does anyone know how to fix this problem?
    (even adding a "CISCO-LWAPP-CONTROLLER" host in the DNS does not help!!!)

  • Wireless controller ha between wlc5508 and wlc 4402

    We have 2 wlc:  a wlc 5508 ( license 100 AP ) and  wlc 4402 ( license 12AP).
    We try to setup when 5508 down, 12 identify AP (important AP -Group A) will join 4402 and all other AP (not improtan AP -Group B)
    wont joint  wlc 4402.
    First, all AP join wlc 5508, 2 WLC have same mobility group.
    After that, we  config 12 APs belongto group A have primary and secondary wlc, group B only has primary wlc.
    When wlc 5508 down, some of APs of GroupA and   some of APs of GroupB join wlc 4402. We test many times and we have differnet result each times.
    is theare any way to resolve our problem?
    Thanks.

    Just to add, make sure that the WLC is running the same code, if not, then make sure the ap is supported on the code that is running on the 5508. The issue with mixed code is the ap will upgrade and downgrade very time they switch to a different WLC.

    Hi,
    we have a Wireless LAN Controller WLC 4402, Software Version 4.1.192.22M (Mesh).
    At the moment there are 6 Access Points in one house, one of them is the root AP. The others are only connected via electrical socket.
    AP’s are: AIR-LAP1131AG-E-K9 / Boot Version 12.3.8.0 / IOS Version 12.4(3g)JMC1
    I think the configuration worked fine over a period of 2 years.
    Now the problem is that the number of access points connected to the controller is changing nearly every minute. At times there is only one AP connected to the controller. So it is impossible for the clients to build up a steady connection. They have to log in via the guest user web interface at short intervals or they can’t see the wireless lan.
    First we thought it would be a problem of one or two “defect” access points. But we replaced 4 of the 6 access points and the problem is still there.
    An example, yesterday:
    13:17 o’clock – 2 AP’s
    13:19 o’clock – 4 AP’s
    13:21 o’clock – 5 AP’s
    13:23 o’clock – 4 AP’s
    13:25 o’clock – 5 AP’s
    13:25 o’clock – 4 AP’s
    13:26 o’clock – 5 AP’s
    13:26 o’clock – 6 AP’s
    13:28 o’clock – 4 AP’s
    13:28 o’clock – 2 AP’s
    Eye-catching is the following message of the log, which appears often: “52       Mon May 16 13:21:56 2011        AP 'AP001d.e557.6fd8', MAC: 00:1d:70:01:bc:20 disassociated previously due to AP Reset. Last reboot reason: power loss
    Also eye-catching is the AP up time. The Root AP is up for over 80 days. But all the other access points show an up time of a few minutes until some hours…but not more.
    Does anybody know what the problem could be?? I read some similar threads but no solution.

    Hey,
    last week I tried to upgrade the controller step-by-step.
    Under the software 4.1.192.35M the problem was still there… access points were often disassociated from the controller.
    There were problems with Software 4.2.207.54M too. The access points couldn’t reach the download-status. The log of the access point said that it could not open the tar-file.
    So I went back to 4.1.192.35M. Of course the controller lost some of its configuration. I configured it new with the same settings as before.
    After it the wireless connection seemed to be a little bit more robust. I asked the users to test the connection at the weekend and this is the answer:
    “so we tested the WLAN during the weekend. The situation definitely improved with respect to before. Authetication is much faster and the connection (when active) is sensibly faster.
    However the connection is still very unstable and it is necessary every five-ten minutes to reconnect (especially for intense network traffic like when watching a streaming content or using VOIP applications. Actually switching off and on again the WLAN card (Airport) often a new authentication is not required. However, without doing so the connection would not resume alone to a working state.
    So what to say? Better than before (thanks) but far from being fixed. From last September to January we did not experience any problem, so it must be something that chronologically happened at the beginning of the year, it is not a systemic problem.
    But there were no changes or anything else at the beginning of the year.
    Do you mean it makes sense to resume upgrading? I’m a little bit afraid of more problems like under 4.2.207.54M
    Greetings Lydia

  • Wlc 4402 errors when trying to join ap

    Hello,
    I have a wlc 4402 controller with software version 6.0.199.4
    now i have problems adding 1131 aps to my controller.
    in the pas i added 15 access points (withouts problems) but
    now doesn't seems to work anymore.
    here's what i got from controller when trying to join
    *Nov 11 12:24:37.739: %LWAPP-3-RADIUS_ERR: spam_radius.c:138 Could not send join reply, AP authorization failed; AP:00:13:c4:93:c1:58
    here's what i got on the AP (console cable on my pc when booting)
    %LWAPP-3-CLIENTERRORLOG: LWAPP Crypto Init (SSC): no certs in the SSC Private File
    Got an idea on this ?
    thanks for help

    Was the AP in automatic mode before? Did you copy the LWAPP recovery image to the AP using tftp?
    All APs manufactured before 2005 or 2006 do not have MIC (manfacture install MIC) installed. You need to use LWAPP conversion tool to convert the AP to LWAPP/CAPWAP; so that the conversion tool will install SSC (Self Signed Certificates) to build the encrypt the LWAPP/CAPWAP control traffic:
    http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
    As LWAPP discovery image is already there, you need to convert the AP back to autonomous mode and use LWAPP conversion tool to conver the AP:
    http://www.cisco.com/en/US/docs/wireless/access_point/12.3_8_JA/configuration/guide/s38trb.html#wp1058472
    I hope that the mode button is not disable on the AP. if it does, I hope that the break key is not disable. If both the mode button and break key are disable, you need to RMA the AP.

  • Software Version Upgrade for Cisco 4402 Wireless Lan Controller

    Hi,
    We have Cisco 4402 Wireless Lan Controller with Software Version 3.2.171.6 and we want to upgrade it to latest version.
    So can anyone please let me know the latest version to upgrade the WLC?
    Also since WLC is running on very lower version is it possible to upgrade to the latest version directly or we have to move it step by step to upgrade this to latest version?
    Thanks

    Take a look at the compatibility matrix below:
    http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html
    7.0.235 is the latest that you can go to:
    http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7_0_235_0.html
    The release notes outline the upgrade process.

    i searched for the regulatory domains difference between  AIR-LAP1041N-E-K9 and  AIR-LAP1041N-A-K9 and didn't find any difference that may affect the operation of this AP.
    just to mention that our configuration in WLC for regulatory domains is:
    Configured Country Code(s) AR 
    Regulatory Domain  802.11a:  -A
                                 802.11bg: -A
    My question is, should i only include my country in the WLC (IQ) to add the requlatry domain (-E) to solve this problem? or changing the country will affect the operation of all working APs??
    Appreciate your kind support,

    Hi Ramon,
    thank you for the reply but as shown in the below link:

  • WLC 4402 username and password expires automatically

    Hi,
    We are facing issue with Cisco WLC 4402 (Cisco AireOS Version 4.2.205.0) and username and password expired automatically. It happens very often. We are not able to retreive the password, so everytime we need to reset(factory default) the Cisco WLC4402 and doing fresh installation.
    Whether it is the hardware issue or software bug.
    Also is there any possibility of recover the username and [password with resetting the cisco wlc4402.
    Kindly suggest on this issue.
    Regards
    S.Manikandan

    Hmmm.. Strange!! are we using any TACACS to manage?? or just the management username and password??
    I guess after 5.2 WLC code or so we have the option of resetting the password without losing the config!!
    Regards
    Surendra

  • WLC-4402+AIR-LAP1142N problem

    Hello all,
    I've got a following problem with bringing up simple wireless configuration. There is a WLC-4402 controller and several remote locations (I am testing one so far). Two WLAN configured (one for employee and the other for guest access - no mobility anchoring used, guest is just mapper to VLAN restricted on the firewall). WLC serves DHCP pools for wireless clients. Problem I am experiencing at the moment is that user with laptop is able to connect to guest WLAN, got an IP but can communicate (ping) only its own IP, the controller IP in guest subnet and default gateway (which is the firewall interface). Traffic to any other destinations never hit gateway (I am running tcpdump on it to confirm). I double checked controller config but no luck so far. Could that be caused by missconfigured tunnel? No ACL or restriction set on WLC - see attached config.
    Thank you in advance,
    Peter

    Is this an open network or have you enabled layer 3 security? Web Auth? I can see you have created a lobby admin account so expect that you use this for guest account creation with web auth..
    When you associate/receieve IP address to the open guest network have you then opened a web browser and authenticated? Until you enter your login details created on the WLC I would imagine that you wouldn't be able to send any data.
    If you have authenticated already, can you check on the WLC that the client is associated/authenticated and is the Corp network ok? Also what is the topology between the WLC/Firewall/Remote sites.
    Cheers
    Mat

  • WLC 4402 + 4 1130AP's.

    Has anyone setup a WLC 4402 and few 1130AP's on their network? Here's the scenario we have VLAN's setup on our network. We want to be able an employee can connect to the internal network and public connect to a DSL Internet. I got the internal employee access the internal network but I couldn't get the DSL users connect to the Internet. Internal network uses DHCP server and DSL users uses Linksys DHCP server. Can someone point me to the right setup/config on 1130AP's to connect to DSL using WLC 4402?

    Make sure you can get the VLAN to the internet before you setup the WLAN. 1st off I would test the VLAN that you have setup to go to DSL on a switcport on your core switch and work the DHCP issues out there and then work on the WLAN. can you ping your DSL router intface from your switch. If you can my guess is that the IP helper address is not set right.
    You will then need to point the WLAN to VLAN you setup for the DSL.

  • WLC 4402-50 with ACS 3.3

    Hi,
    We want to use ACS to authenticate an ssh or http connection to a WLC 4403-50 4.2.99 using TACACS+. On our ACS 4.2 test server it works fine. Configured identically on an ACS 3.3 appliance we are not able to log in although we do see a successful login in the Passed Authentications report withing ACS.
    Is there an incompatability between the WLC 4402-50 with ACS 3.3?
    thanks
    Bob

    The Cisco Secure Access Control Server (ACS) provides authentication, authorization, and accounting (AAA) services for users of the wireless network.
    It is also possible to employ a WLC controller strategy that uses an N+1 approach. When using N+1 architecture, each WLC is configured with a WLC that is designated as a backup WLC in the event of a failure. This controller is not used until there is a failure event upon which all APs using the failed controller switch to the backup WLC. This cost-effective approach provides a high level of availability in the event of a single WLC failure scenario.
