Cisco Wireless :: How To Join The AP To WLC2500

May 16, 2013

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
IP Address: 192.168.1.225
version: 7.4.100.0

Cisco Wireless :: LAP1242 Cannot Join WLC2500?

Jan 16, 2013

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.

Cisco Wireless :: 1552 MAP Can't Join Network Through RAP

May 6, 2013

I have configured a 1552, that is wired to network, as "Bridge" then "RootAP".
 
After reboot, I can see a MAP trying to join the network, in the "simple" logs of the controller :
"Mon May 6 17:29:43 2013   Mesh Node '04:da:d2:1f:4d:6f' failed to join controller, MAC address not in MAC filter list."
 
As I have done for the RAP, I enter this MAC address in the MAC Filtering area under Security tab. But this action doesn't solve the problem, I continue to see this message in the controller logs !
 
If I open a SSH session on the RAP, I can see this block of debug messages repeat all the time :
*May  6 15:29:33.163: %MESH-6-ADJ_VIDB_LINK: Mesh neighbor 04da.d21f.4d6f VIDB Virtual-Dot11Radio0 dot1x control
*May  6 15:29:33.167: %LINK-6-UPDOWN: Interface Virtual-Dot11Radio0, changed state to up
*May  6 15:29:34.167: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Dot11Radio0, changed state to up
*May  6 15:29:43.223: %MESH-6-LINK_UPDOWN: Mesh station 04da.d21f.4d6f link Down
*May  6 15:29:43.423: %MESH-6-ADJ_VIDB_LINK: Mesh neighbor 04da.d21f.4d6f VIDB Virtual-Dot11Radio0 going
 
When I take a look into detailled debug messages of the controller I can see this :
*spamReceiveTask: May 06 17:30:44.364: #LWAPP-6-RADIUS_AUTHORIZATION: spam_radius.c:242 The system could not send join reply, AP authorization failed; AP:04:da:d2:1f:4d:6f
 
I don't know why the system talks about dot1x or Radius Authorization, and if this is the source of my problems. On a other hand, I can see in the debug messages that there is a 2 hours lag time between controller (correct time) and RAP (incorrect, I suppose it synchronize with the controller?)

Cisco Wireless :: AIR-LAP1242AG-K9 Could Not Join 2106 WLC

Jul 7, 2011

I setup a mini wireless LAN network lab with a not for resale 2106 wireless lan controller and a sales  air-lap1242ag access point. I do not have a DHCP and DNS in my lab environment. I have configured the WLC with the basic configuration using the CLI wizard, i also configured the WLC as a DHCP server for clients that will be connecting to the APs associated to the controller.
 
I powered up the AP and connect the ethernet port directly to the controller, the controller issued an IP address to the AP, the AP downloaded a new operating system from the controller but failed to join the controller.
 
I check both debug message on the controller console and the trap messages on the controller's GUI  and it say the AP could not download a configuration from the controller and it is beacuse of invalid license. Below is the trap message:
 
Configuration Phase Statistics Requests ReceivedResponses SentUnsuccessful Request ProcessedReason For Last Unsuccessful AttemptLast Successful Attempt TimeLast Unsuccessful Attempt TimeLast Error SummaryLast AP Message Decryption FailureLast AP Connection FailureLast Error Occurred Last Error Occurred ReasonLast Join Error Timestamp 
 
Also, I tried to log into the GUI of the AP using the both the username and password  ''Cisco'' but I cannot get into the device. I can only get in through the CLI. In the CLI, almost all the commands I enter gives an error the it is disabled. I don't know what to do any more, I want to know if the access point is faulty or i am not doing the right thing.

Cisco Wireless :: AP Does Not Join The 5508 WLC When NAT Is Configured

Nov 14, 2012

A customer runs a 5508 WLC for quit a while. several dozens AP's are spread all over Europe an run just fine. All the AP's have a VPN based connection over an MPLS service provider, so we are using 10.x.x.x addresses only. We have upgraded to release 7.2.111.3 to support OEAP 600 and we have configured NAT in the Firewall as well a policy to support the home office AP. Everything works fine until the switch where the WLC was attached to crushed. From this moment on, all internal AP's ar no longer able to register at the WLC. A log at the console port on an AP shows that it tries to access the external (NAT) IP address. We had to remove the NAT flag to support the internal AP's.

Cisco Wireless :: 3502i Cannot Join Controller?

Oct 15, 2012

When we were installing some new APs, were plugged in to ports that were not configured on the WLC management VLAN.
 
This is the illustration
 
WLC management VLAN is VLAN 80 Management VLAN of infrastructure (Switches routers) is VLAN 10
 
The APs were plugged in to VLAN 10 and they were not able to associate themselves with the controllers.
 
Through research, those APs were getting a wrong IP address,
 
I did the Mode button, pressed for 30 secs, but this did not fix the problem, i thought it was going to clean the flash and bring the AP back to factory default I do not believe this happened.
 
We also added the cisco-capwap-controller.localdomain  to our DNS servers, and then I rebotted the APs and still no luck.
 
What fixed the issue is we had to go to the DHCP server, release the IP addresses and we found those based on the macs of the APs. What is we do not have the mac addresses?
 
Now that I have the DNS entry created, if I plug in an AP on the wrong VLAN port will I be able to see it?

Cisco Wireless :: 3502i Cannot Join 5508

Sep 25, 2012

I have a 3502i(AP_1) that will not join a 5508 WLC(WLC_1)(code 7.2.103). The 3502i(AP_1) will join 4402 WLC(WLC_2)(Code 7.0.230). I have another 3502i(AP_2) that will join the WLC_1 & WLC_2. I am using capwap discover through DNS and hard coding the primiary WLC to AP_1 & AP_2. When I debug capwap events and errors, I see the static capwap messages and replies. Both of the WLC are on the same subnet. I have defauted the AP_1 and it joins the CISCO-CAPWAP-CONTROLLER as expected. When I change the Primiary WLC to WLC_1 it goes back to the CISCO-CAPWAP-CONTROLLER. If i change the primiary WLC to WLC_2 it joins. If I change the primiary back to WLC_1 it joins WLC_2 even though it is not a secondary. I know the previous joined WLC are stored in NVRAM, so that might be why it is doing that. I can join other ap to WLC_1 just not this one.

Cisco Wireless :: No Join Request Going Out With 1131

Aug 10, 2011

Trying to get an lightweight AP to register with a controller, never seen this one before where the Discovery request is going out to the controller, the discovery response is coming back, but then nothing. At this point the AP should then send a JOIN request, but it just doesnt.
 
I am using L3 LWAPP, and have the AP statically configured. its a 1131, connecting to a 5.1.151.0 in a WISM. I have run a wireshark and can see the discovery going out, its response coming back, but then nothing (the debugs below also back this up). I have also jumped on the controller and can see the discovery responces are going out but it says no JOIN's are coming in. I'm aware this is an old version of controller but still..
 
I've tried many different IOS on the AP, including the one it came with in the box, other previously successful IOS and the IOS that 5.1.151.0 dishes out to its registered AP's, multiple AP hardware resets, controller reboots, tried different controllers. etc... What would cause this? Possibly something in the response? See info below:
 
AP
LWAPP Static IP Configuration

Cisco Wireless :: AIR-LAP1262N-A-K9 Not Initiating Join Process?

Sep 11, 2012

I foolishly put this 1262 into Bridge mode.  The AP didn't accept that.
 
It had been joined to a 5508 running 7.2.110.0 and was running fine.
 
I've loaded on ap3g1-rcvk9w8-tar.124-23c.JA5.tar using the  archive download-sw /overwrite /force-reload tftp://10.192.175.119//ap3g1-rcvk9w8-tar.124-23c.JA5.tar command.
 
When the AP reboots it has retained it's hostname from its CAPWAP days and indicates it is in DISCOVERY:  %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY.
 
It gets a DHCP IP but never tries to find a controller.  DNS on the subnet resolves CISCO-CAPWAP-CONTROLLER (& lwapp) to the 5508 mentioned above.  I use this port for priming all my APs.
 
Are there other residual files in nvram: or flash: I need to remove?  Is this thing now just a fancy paperweight?
