Cisco Wireless :: 4400 Series Controller Blocking 802.11a/n Radio Interface Of 1250 AP
Dec 19, 2009
We are facing an issue with a customer where a Cisco 4400 Series controller is blocking the 802.11a/n Radio Interface of a 1250 AP. The radio shows as down on the controller GUI. The error message on the GUI is that the 'Regulatory Domain' is not supported. This can be seen from the attached screenshot. Also relevant parts of the WLC configs are attached. WLC: Cisco 4402 WirelessWLC Country: SADevice: Cisco Lightweight Access Point 1250 (LAP) is controlled through the 4402 Cisco Wireless LAN Controller (WLC)The operating system version of the LAP: c1250-k9w8-mx.124-18a.JA version of the WLC: Software Version 5.2.178.0 The problem is that the controller shows that the 802.11a/n Radio Interface in Radio Slot # 1 is always down , the customer tried to manually 'no shut' the AP interface from the console and it worked , but obviously this solution would not work as the configuration cannot be saved (LW AP).

I've download a login.html into the controller successfully, but when I preview the page there isn't an accept button. Do I need to create the accept button with the html file or is there some place I need to enable on the controller itself. After download the .tar file I reboot the controller but no luck. I also create a java script button redirect but it didn't redirect to where I needed to go. It just stuck on the splash page.

I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect. But I am not having any luck getting into a controller. Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc. This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers. Niether of which are set to "Master" either.

We have a customer that have 2 5508 as primary and backup controller and a 4400 as an anchor controller. We plan to upgrade the 5508 to 7.3.112.0 and the 4400 is already 7.0.116.0. Will there be any issue if the anchor controller is not the same code as the foreign controller? Do I also have to upgrade the acnhor controller to 7.0.240.0?

I've just got a new AP 1250 series, and I was trying to configure the Radio for the 2.4Ghz spectrum using the interface dot11radio 0 and I've just noticed that this controller is not present so I cannot configure it so I wonder is it could be a HW problems as it looks to me or there is another way to enable this.
I never have an issue like this before so I want to first check with you before going back to our vendor.
Here is some of the details I get from the AP itself:
System image file is "flash:/c1250-k9w7-mx.124-10b.JDA3/c1250-k9w7-mx.124-10b.JDA3"

I am running the upgrade tool on Aironet AP1230B-A-K9. I can't join the controller by using the upgrade tool. the error is "AP does not have Supported Radio". What radio is the upgrade tool or controller look for on Aironet 1200 series? This AP is running 802.11b. However, I have several APs which the same model is running on the same one controller. The controller is model 4402.

I have a Cisco Series 4400 WLAN controller and I'm trying to connect a lightweight AP to the controller. I have already assigned the switch port to use my wi-fi VLAN, and have connected the AP to the switch. After a few minutes, the light on the AP goes from green to light blue (indicating it's serving clients). When I log into he wi-fi controller to look for the Ethernet mac address of the new AP, I do not see its Mac Address. I want to be able to rename the AP to reflect where it will be used, but need to select the AP via its Ethernet mac address before I can make any edits like changing its name etc. I've gone through the "monitoring" menu, selected "All" and still do not see it in their via its MAC address. I also will select the "wireless menu" which lists all the AP's on my network, listing in order from on the longest running, to just powered on.Is there something I'm missing like a "re-scan" that scan's all devices?

I'm looking for a document that states the best practices for WLC configurations (Management/Security/AP's..etc). I can currently only find the following document:URL
But this document has last been updated in 2008, in a few days that's almost 5 years ago, and we all know how quickly technology is evolving. 10Gb wireless is around the corner, with 1GB starting to go production now. This document also mentions the 4400 (which is end of life).

give me the run down on the features removed from the 4400 series in the 2500 series? Obviously 4400 is now EOL, and so i cannot purchase new. Therefore I was looking at the 2500 for my implementation to save costs also.I would like to have two SSID's, running seperate VLAN's, one voice, one guest, trunk the link to the AP's, which will be 1131AG or newer, N possibly. Voice needs to be encrypted with WPA or WPA2, guest needs to be open using the guest access feature. Here's a sample but with EAP:
[URL]
Is this supported to have WPA on one SSID and Guest access on the other? i did spot a paragraph in the 4400 manual stating that certain restrictions apply regarding one SSID having encryption and the other being guest mode?I notice also in the WCS documentation, it doesn't explicitly state it supports the 2500 series under the managed devices section?

I read the configuration guide about the 7.3 release. And I figured out that you will need a hash key for establishing a mobility group relation between a controller and a virtual controller. The 7.3 release for the 5500 series works fine for me.But the latest release 7.0.235.0 for the wireless lan controller series 4400 does not have a functionality to add a hash key while creating a new mobility group member.The command "config mobility group member hash" is totally missing. How to establish a mobility group between a 4400 controller and a virtual then ?

I want to configure a Cisco Wireless Lan Controller (4400 and 5500 series) with to data ports for failover? I think the primary and secondary ethernet connections should be configured as trunks. I cannot find anything on CCO about this or on the internet per se. I know how to configure for failover with APs but cannot find anything on how to configure the controller in case an the ethernet port goes down.

We have a Cisco 4400 series wireless controller deployed as a Guest Anchor in a private DMZ. We have 13 foreign controllers anchored to this for Guest Wireless. We recently anchored 17 additional controllers to this Anchor controller. Since we have done that, periodically on just 3 of the foreign controllers, the control path shows down on the mobility peer, then comes back up. We have had this issue in the past, but it resolved itself. However, now we are seeing this issue again. Are we reaching a limit on EoIP tunnels? I have read that there is a max of 71, and that is per controller, not SSID. We do have a firewall in the middle but all necessary ports are open.
We have had this issue for quite sometime, it just does not happen frequently. Since we have added the additional controllers, it is now happpening very often, but only with 3 controllers. There is not much in common with these 3 controllers. 2 are 4400 series, and 1 is a 5508. All 3 are local on a campus LAN, different networks. Could it have anything to do with memory or utilization?

We have two 4400 WLC's. We have around 20 access points in our network.If we assign controller1 as primary for half of the access points and controller 2 as primary for the other half, does this mean the association of the ap's indicate load balancing by the controllers. Does this mean wlc does load balancing as different ap's associate on different controllers. or does it only server as active-standby wlc.

I am wondering if anyone has seen this before. We have about 50 AIR-LAP1242AG-E-K9 access points connected to a WLC5508 running 7.4.100.0. These were all being used as autonomous APs previously and were converted when the controller was installed. About 12 of these have a lovely feature where their radio interface goes down at random. The radio is still in enable mode but the opertational status is DOWN. It seems to happen particularly when there has been a power outage and the AP rejoins the controller. All of the other 1242s are fine and never sees this problem. The APs are all on power injectors.
Once the radio is down, the only way I can get the to come back online is by doing the following:
1. Set the radio admin status to "disable" and apply
2. Turn off CDP
3. Reboot the AP Wait until the AP is back online and registered on the controller
4. Enable the radio admin status and CDP.
If I do not remove the CDP setting I cannot bring the radio back to "UP". I know we had previous issues with autonomous 1242 APs that did not like CDP being enabled. Have I perhaps got a bunch that are like that? Despite these having operated as autonomous APs they are AIR-LAP1242 from the factory.

I have a couple of 114n APs in my network and the CAPWAP uptime and AP uptime are almost the same. But there is one which always resets after some time. I have moved across to another switch port but the issue persists. I have other 1141 and 1131's on this switch and no problems. The keep alives between the AP and Controller is regular. I can't get more info from the traps as the reason code is always;
" AP associated to Controller is UP. Reason: Radio interface reset due to Init"
"AP associated to Controller is down. Reason: Radio interface reset"
"AP associated to Controller is UP. Reason: Radio interface reset"
####Only 2ice was the reason code "Operator changed 11g mode". I have seen some posts about similar problems but there hasn't been any concrete solution provided.
note that RLDP is disabled, Primary discovery timer is 120sec, and the version is 7.098

I have a Cisco 2500 Wireless Controller connected and controlling 5 Cisco AP's. Everything works fine except one device.
This device is used to connect to our AP wirelessly and then any of the wireless laptops can use programming software to connect to the device and program through it. I can successfully set up our device on the network and all PCs can ping it, but the programming software refuses to connect to it. I spent an hour and a half on the phone with the device people who assure me its the network. So, I bought in a cheap Linksys router, hooked one laptop up to it and configured the device wirelessly. With that, the programming software works.
what should I be looking for in the Wireless Controller that may be blocking direct connection to the device even though I can ping it?

I have 3 4400 WLC's that implemented at 1 main site within a mobility group. I am looking at implementing wired guest authentication with a splash page for username and password access. I have followed the documents and suggestions about how to configure it. I created a layer 2 vlan (700) and then created a VLAN (151) that wired guests will get an IP address from. I then configured a WLAN with the ingress interface being VLAN 700 and the egress interface being VLAN 151.
All of my controllers are running code 7.0.116.0. When I go to do a test scenario with a wired client, I have the switchport setup for VLAN 151, which they get an IP address from, but when they try to go to the Internet, they don't get the splash page. Why I am not getting a splash page or even if this scenario is possible?

I know how to access the GUI from the service port. However, I am not able to access from Port 0. IPs have all been properly set. We have a management VLAN in our enterprise. I have configured the WLC management interface for an ip on that subnet. Port 0 is connected to a 3560G switch. I have set the switch port to be an access port to the management vlan and I have tried to set the switch port as a trunk, with the native vlan set to the management vlan. I am not able to ping nor access the web GUI remotely via the management vlan.

in one of the sites, the client has an exisiting 4402 controller which he moved to the DMZ in order to set it as an anchor & he purchased two new 5508 controllers to control the corporate APs. I configured all the parameters needed for the guest anchoring & then I tested the connection but there was an issue. (all the controllers are running the same firmware version)after testing the setup, the guest users could get an IP from the internal DHCP of the anchor controller (in DMZ), but then they cannot reach the internet or anything outside the anchor controller.Cisco confirmed that the 4400 is fully compatible with the 5500 to work in an anchor-foreign secnario as long as they are running the same firmware version. yet, when I temporarily used one of the 5500 controller in the DMZ as an anchor & I applied the exact same configurations on it as the 4400, it worked perfectly without any issues.
note: on the anchor controller (4400), the management & AP-manager interfaces reside on the same subnet & the wireless guest SSID is also mapped to the management interface. (may be this setup is causing the issue) but on the 5500 it is working just fine?

I converted a Cisco Aironet 1142 Lightweight access point to Autonomous and at first it works properly but every some days the dot11Radio0 interface is down (similar case than the cisco support community case "Autonomous 1142 AP shuts down 2.4 radio interface" The 802.11g radio shows as “Dot11Radio0 is reset, line protocol is down” while the 802.11a radio appears to be up and running, I have to reload the device so that the Dot11Radio0 is up again.

I have a 5508 WLC licensed for 100 APs. I have 1 - 1042 LAP connected for testing. I have DHCP configured for the AP, and it gets an address of 192.168.254.100/24 - the controller's management interface is 192.168.254.99/24. I can see that the AP is getting an IP and I can ping it from the controller. However, I simply do not see the AP associating. I enabled capwap debiugging and watched the events, but I didn't see anything crazy that clued me in. What am I doing wrong?
The controller is v6.0.199.4
Every time I have set these up in the past they have been pretty straight forward. I haven't gotten too deep into the config on the WLC becuase I don't want to cause more issues.

I have a customer whom has six LAP1131AG-K9 but no controller and they are interested in one of the new 2500 series, specifically a AIR-CT2504-5-K9 with a 5 AP add-on license to bring total AP capacity to 10. I can't determine clearly if this controller will work for these older AP's prior to them making the jump to 802.11n via the 3500 or 3600 series, looking to the community to confirm.
