Cisco Wireless :: WLC5508 - Ipad2 Can't Join Wi-Fi Using Wpa2 AES

Apr 12, 2012

we have a cisco WLC 5508 on which few SSIDs are configured, and two kinds of APs: AIR-LAP1142N-E-K9 and converted AIR-AP1141N-E-K9.
When in WLAN settings we leave WPA2 policy and AES encryption, iPads2 can connect without any problems to AIR-LAP1142N-E-K9, but there is no connection to converted AIR-AP1141N-E-K9.  MacBooks, iPhones are connecting without questions.

When we set WPA2+TKIP everything is cool, but other Apple devices can't rich 802.11n speeds((
With only WPA2+AES or both WPA2+AES+TKIP enabled on a WLAN the WLC gets such messages :
Decrypt errors occurred for client xx:xx:xx:xx:xx:xx using WPA2 key on 802.11b/g interface of AP xx:xx:xx:xx:xx:xx
But I know that it can happen when you offer funny encryption combinations that client doesn't like (wpa1+aes, wpa2+tkip). But the advise to try to only enable wpa2/aes for some reason doesn't work.

Cisco Wireless :: AP1142 No Longer Joins Controller - WLC5508

Sep 15, 2011

Two months ago I installed a WLC5508 with sw r7.0.116.0 and we installed 8 AP1142 as a start.

10 days the customer calls and says that the wlc logs error messages that says there is an IP-conflict with the management-interface. The conflict source is its own ip-adress!!! He reboots the WLC but the error message keeps coming. After a short while he notices that there are No APs on the WLC...!!!...
After some discussion I suggested that he should disconnect one of the two gig-ports of the WLC (LAG was enabled and in use). He did so and rebooted the WLC for good measure ...  The IP-conflict disappeared but still no APs.....
In the DHCP-server (MS Win2003 server), in the AP-scope we also see that the "leased adresses" fills up with "BAD_IP_ADDRESS" (or the sort ...  :-/  )
The setup is like this:
- WLC5508 running r7.0.116.0
- WLC has LAG activated and is connected to two different Cat3750G that are stacked
- The management if of the WLC is on the same subnet as the AP1142s, no other hosts on this subnet
- WLC management interface on own subnet as the only host (+ def gwy...)
- APs on their own subnet, no other hosts
- When the APs gets a IP-adress it is possible to ping them from the WLC!
- All VLANs/interfaces on the WLC is tagged, ie a "pure" trunk between WLC and 3750-stack
- Option 43 configured on the AP-scope
- All APs is connected via Power-injector (PWR-INJ4)
WLC5508 => LAG => 2x Cat3750G => TRUNK => Cat2960 with 1x AP1142 => TRUNK => Cat2960 with 6x AP1142
What we have done so far:
- Made sure the port-channel on the 3750-stack was configured: port-channel load-balance src-dest-ip
- Physically disonnected on port of the WLC
- Do "shutdown"on port gig-ports on the 3750-stack and "no shut" on only the one that is still physically connected to WLC
- Do "shutdown" on all AP-ports in the 2960-switches. Clear the lease-pool of the DHCP-server, Deactivate scope, Reactivate Scope and finally "no shut" on all AP-ports
Nothing worked, still no APs on the WLC.
I the connected my PC to the consloe of an AP that was easily accessible and powercycled it. The output can be seen below, the most peculiar was the line : " *Mar  1 00:15:53.351: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination"
1. It worked initially but after the ip-address confilct and reboot of WLC no APs associate to the WLC. Why??
2. The error message on the AP console: "*Mar  1 00:15:53.351: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination" What does this mean?
3. Since the AP gets an IP-address an it is possible to ping WLC -> AP, is there some freakish ogre in the Cat2960 that eats up the CAPWAP-packets??

Cisco Wireless :: AP C3502-I-K9 Does Not Join Controller

Oct 18, 2012

Network environment: (well configured and working fine)
2 AIR-WLC2106-K9 - Software Version
2 AIR-WLC2112-K9 - Software Version
10 AIR-LAP1252AG-T-K9 - Software Version
10 AIR-LAP1131AG-A-K9 - Software Version
I am adding a Cisco AP c3502-I-K9 to network.
It does not join any of the controllers.
Led is cycling through green, red, and off - that means "discovery/join process in progress" - never ends.
As wireless network is doing fine, I had only added to dhcp server dhcpd-subnet.conf file the above configuration:
class "Cisco AP c3500" {
match if option vendor-class-identifier = "Cisco AP c3500";
option vendor-class-identifier "Cisco AP c3500";

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 :: 3602 AP Cannot Join 2504 Controller

Oct 16, 2012

This is a new setup and has not worked yet. I have multiple 3602 APs and one 2504 Controller. I thought initially I could plug-in an AP into one of two POE Ports on the 2504. During debug mode I see that it has low power, was suprised that the 2504 switch can't fully power the AP? Is this correct?Anyways I have another POE switch that I am using with ample power. The configuration for my wireless is that it will be completely segmented off of my internal network as this is for guest access. So DNS servers are external so I cannot create host entries for the AP to discover the controller. With that being said I believe that is just one way for the discovery process to happen. I have my controller management interface and DHCP scope on the controller on the same subnet plugged into the same POE switch. The AP does seem to get a DHCP address and I can ping the controller from the AP. I cannot get any further then that. I will not join the controller and the radios get disabled. I get messages such as "discovery response from MWAR is rejected. I will post a debug log of the AP and its bootup process. This is new equipment so I would assume the firmware is somewhat up-to-date and the 3602 AP is somewhat the latest model.

Cisco Wireless :: AP LAP1142N Can't Join Controller - 4402

Apr 11, 2012

1) AP was originally running a standalone image.  I booted it into a so-called ROMMON or AP mode (ESC is the right key to make it boot into this mode).

I found a recovery image in its flash - c1140-rcvk9w8-mx. I made the AP boot from it by using "set" command and I see that it start booting using this recovery image. Here goes the question. Do all AP settings matter ? E.g. when I run "set" command from AP I see the following:

How do I initiate the discovery process again to make this AP to join? Should I convert it back to autonomous AP and then LWAPP process again? I can ping the AP from the controller and the AP is in the same VLAN with controller.

Cisco Wireless :: 1142 AP Will Not Join Controller Through D-Link POE Switch

Apr 1, 2012

I'm trying to use 1142 APs with a 2504 Wireless Controller through a D-Link 48PT GBIT XSTACK SWITCH (DLI-DGS-3120-48PC/SI).At any rate, the 1142 AP joins with the wireless controller ONLY when I attach it directly to the controller.  When connected directly to the controller the AP functions normally and all is well. When I attach it through the D-Link switch, the AP flashs green several times, indicating that it can't find the controller.  I suspect that there's some setting on the D-Link switch that's preventing the AP from seeing the controller.

Cisco Wireless :: LAP1240 - H-REAP Enabled AP Doesn't Join HQ Controller

i have configured cisco LAP1240 in H-Reap Mode for multiple branch offices with Local switching and central authentication. one of the branch's AP does not join the controller in HQ while the others are all ok. i have firewall only in HQ, i did priming first for all APs like let them join the controller and configure controller IP in high availbility, and H-Reap config and assign SSID to map with the branch local vlan. when i faced this issue first time i brought back ap and configure a static IP address for AP than recheck them again but the problem still same. since i have only one firewall in the network and also other branches joined the controller through that firewall and no issues.

Cisco AAA/Identity/Nac :: Force ACS V.5 To Join Domain With Certain Controller?

Sep 5, 2012

I try to join an ACS v. 5.3 to the domain.  For my acs in Location A, I can join without problems using my account. When I try to join the ACS in location B to the same domain with the same account, it doesnt work.I looked at the debug log files for the ad client, and noticed, that the ACS in location B goes to a certain Domain Controller. However, I would have expected the ACS to contact another DC, which is located on  the same location as the ACS ... this doesnt happen.
My question:  How does the ACS determine what DC to contact ? Is it possible to force the AC to join by connecting a certain DC ?

We do not have a backup WLC, but are looking to purchase one. What I would like to know is, are there any problems with the secondary WLC being installed in our Main Data Site in Europe? These two main sites are connected via a 10M MPLS WAN.
So all the remote sites could still connect to the WLC in the US, but in the event of a WLC failure in the US, they would need to fail over to the site in Europe
