Cisco Wireless :: AIR-WLC4402-50-K9 - After WLC Reboot Only One Wireless AP Can Join
Mar 1, 2012
I have an issue with my primary WLC AIR-WLC4402-50-K9 running version 7.0.220. After a reboot of the WLC only one AP can join, all others are rejected. After waiting a few hours (about 3) all APs can join the WLC. What I have done is a software upgrade (from 6.0.199.4) on both primary wlc (wlc with the issue) and backup. Following procedure:
1. Reboot primary wlc so that APs failover to backup (succeeded with no issue).
2. Upgarde software on primary wlc
3. To failback all APs from backup to primary I reboot all APs, so that they join again their primary wlc.
A reboot of the first AP was fine, It joined the primary wlc, get new software downloaded, rebootet, joined wlc successful again. Then rebooting the next AP. But this one then does not join the primary wlc for several hours. But it is also not falling back to the backup wlc as the primary is up and reachable. I tried a reboot with the next AP, but same behavior. I was waiting then until both APs were joining the primary wlc again. This happened after around 3 hours. After that I have rebootet all other APs on the backup wlc also. All was fine they immediately joined the primary without any issue. There are no log messages during the time when the WLC does not allow APs to join.. I had similar behaviour last year with version 6 when I rebooted the device. So I dont think this is software related. Also I dont think it's a configuration issue as 1) I have another WLC that uses the same backup controller and this one has the same configuration but works fine also after a reboot. 2) why doesn't it work after a reboot for a few hours, but then all is fine without any config change. After a few hours all is fine for months (until the next reboot).

info regarding my LAP521 access points that are refusing to join the WLC4402-12.This is my first lightweight access point implementation and I have 3 LAP521's and 1 AIR-CAP3502I-E-K9 access points on my network.They are meant to pick up ip address from external dhcp server and then join the WLC but only the 3502i joins successfuly while the 521's get dhcp address but do not join the WLC. From the logs, I can see that the WLC is discovered by the 521's and even get a response message from the controller but they are still unable to join as shown in the screenshot below.My WLC is running software version 7.0.230.0 and the 521's are running an lwapp image version 4.2.61.8.

We have 2 AIR-WLC4402-K9 devices at a remote location that will both drop their network connections some undetermined time after a reboot. We cannot reach them via telnet, SSH or HTTP. In fact, we cannot even ping them once they drop connection. The only cure we've found so far is to power-cycle the controllers. The controllers are in separate rooms and connected to separate switches. We've confirmed the links are configured as trunks and have the correct speed/duplex settings. I tried updating the IOS & boot loader on one of them but that had no effect on the problem.

I have a Cisco 4402 WLC running version 4.2.112.0 controlling 20+ AIR-LAP1242AG-E-K9 access points running IOS 12.4 (10b). I'm trying to setup an additional AP as MESH. When I try to change the mode from local to bridge, on what will be the rootAP, I get a message stating that bridging is not support on this unit.

I have one WLC 4402 & arround 29 Access point (1130) in our enterprise network. Wireless users LAN segment is diffrent from wired users.Wireless users like Laptop users, Mobile users & ipad users which are connetced with this wireless & using enterprise network.
Presently we are using WEP mode for security key. This WEP key are week & can be cracked easily. so security point of view i want to put strong encription mode.Presently i do not have any radius server.I found there are some modes are available Like WPA, WPA2 with PSK etc.
will there any problem with wireless users to access application after changing the mode? Which mode will be stronger & could not be crack. Could we achieve without radius server or not?

Our costumers has implemented 2 AIR-WLC4402-50-K9 with Software Release 7.0.98.0, the wireless infrastructure consist in 2 Root-Mesh-LAP and 8 Mesh connect over-the-air to deploy outdoor coverage.
All the LAP are Aironet 1520 Series Mesh Access Points with equipped with 3 antennas for 2.4GHz and 1 antenna for 5GHz (backhaul).For one year all seems to be ok, yesterday after a power outage of one Mesh-Root-LAP, 5 Mesh-Lap continues reload each 10-12 minutes, on the WLC Log you can see event like a reboot from AP Console, on the LAP console i can capture this event before the reload:

What does it mean? That the beacon signal trasmitted from Root-Mesh-LAP cannot reach the Mesh-Lap and so the Mesh-LAP force a reload?Where we should search the cause? In the power instability or in a interference on the 5GHz radio interface?
On one of mesh Lap I found a strange reason for a releoad:AP1780-Mesh uptime is 11 hours, 10 minutesSystem returned to ROM by power spike

my question regards to a pair of WLC 4402 with 7.0.98.0 software.Actual, our security policy does not really allow any peer-to-peer communication in a wireless LAN. Therefore we set the 'P2P Blocking Action' to drop, and the 'Broadcast Forwarding' feature to disabled (default).But now there is a special requirement for two mobile endpoints to communicate with each other, because one device controls the other.To test the communication, we first disabled P2P Blocking (without success) and further enabled Broadcast Forwarding to bring the communication up. Now it works, but the configuration disagrees with our policy.
1. Is there an alternative configuration as described possible, so that we do not violate the security policy? To allow only p2p connection between the two devices, ist should also be possible to drop any else by an ACL. But how to fix the problem with the broadcast, because of the needed ARP? My idea was to use a static ARP entry, but as far as i know, one of the both devices is not able for it.
2. Because, I did not find any detailed documentation:
2a. with enabled Broadcast Forwarding, the controller forwards all broadcast for any configured SSID, right?
2b. is the broadcast limited to the source VLAN/SSID?
2c. is the broadcast limited to an AP, to an WLC, or is it broadcasted to every AP on every WLC that has the relevant SSID?
we already have two new 5508 but not in an operational state now, because we plan to implement new 3600 APs.Do these WLCs offer more/another circumstances or possibilities?

I made a lot of tests during some days with a wlc4402 and everything was ok.
One day when I tried to reset the system I had a lot of errors (see attach) and could not go on. After changing the image the following output appeared: "RAM Disk Image Integrity Check Failed (Bad Magic Number) Hanging". Now I have no response from the controller.

I have AIR-WLC4402-50-K9 WLC i that current IOS is 7.0.98.218 and i upgraded with 7.0.116.0 IOS but after upgrading and reboot the WLC from 15 access point 3 access point are not coming up and 12 are coing up and working fine (4 1142 and 11 1131 series access point) 3 which are not coimg is 1131 series access point. when i login with console to 3 access point its rebooting 2 times and coming on ap: prompt.
In between that i reloaded the WLC one more time because from 15 acess point only 4 aceess point are came up and i also cleck the show boot on wlc its output is 7.0.116.0 (default) 7.0.98.218 (active) so i reload the wlc and checked out of 15 acess point now 12 acess point are up and still 3 are not. And i also checked the output of show boot command its 7.0.116.0 (default)(active) 7.0.98.218
So i things its because of when 2nd time i reload the wlc the remaining 3 access point are getting.

We are using WLC4402 for our Aironet 1240AG access points. The clients are connecting to the access points and are authenticating to the RADIUS server. I am seeing the logs in Server 2008 but they are being rejected due to Network Policy on the NPS server.
Where do I see the Authentication Type on the WLC4400 or the 1240's? In order for the clients (authenticated via Active Directory user) I have to set the Authentication in the NPS Connection Request Policy to "Allow clients to connect without negotiating an authentication method".
I do not have a certificate on the server and my method options are MS-CHAP-v2, MS-CHAP, CHAP, PAP, SPAP, and allow without negotiating. This RADIUS server was moved from Server 2003 IAS to Server 2008 NPS and there were no issues in Server 2003 IAS. I have all authentication methods allowed and it still gives me the error below. Only when I check "Allow clients to connect without negotiating an authentication method" it allows the authentication to proceed.
Client Machine:
Security ID: NULL SID Account Name: Fully Qualified Account Name: OS-Version:
Called Station Identifier: 00-17-a2-87-54-00: SSID NAME
Calling Station Identifier: 00-41-96-b6-e3-27
NAS:
NAS IPv4 Address: 192.168.90.24
NAS IPv6 Address: -
[code]...
Reason: The user attempted to use an authentication method that is not enabled on the matching network policy.

I have a WLC 5508, AIR-LAP1142N APs and a SSID for students to connect to who bring their own device. I am still testing this and it has not been rolled out but I am running into some serious issues with joining the network. I am authenticating them through a RADIUS server (2008 R2). Problem: many of them cannot connect because they are lacking the certificate.
1. What is a good setup for authentication in a BYOD environment
2. If my setup is good what can I do to allow kids to use their computers on the wireless either without the certificate (which I know is unlikely) or what do I need to have them do to connect. I am hoping it does not involve hard wiring and getting the certificate from the server.

I am new to Cisco wireless solution and would like to ask how to add the AP to the WLC properly. All Cisco 1041 and Cisco 2500 WLC are new. I connect those AP and WLC to the switch without any VLAN tag and the AP can gain the IP address from our DHCP correctly. However, the AP 1041 could not join the WLC successfully.
WLC: Cisco 2500

I have some LAP1242 which by mistake were bought for Mesh. I am trying to convert them to LWAPP so what I did first was to convert them to Stand Alone then to LWAPP but I cannot get the AP to join the WLC and sends several error logs.
I attached some logs taken from AP and WLC so that you can figure out what's going on.
I wonder if I have to remove anything from flash either on SA or LWAPP mode (I know that in some cases you have to delete privete-config in order to avoid the AP taken previous configurations). By the way I think I had never seen this c1240-k9w8-mx.124-25e.JA2 on an AP IOS before, I wonder if it has to do with the mesh thing.
