Cisco :: Associating Light Weight AP To Specific WLC5508
Feb 11, 2013
At the present, we have two WLCs (5508). There are a total of 84 LAPs (1242AG). One controller is configured as the master controller in which all our APs associate to. It's currently running software version 7.0.116.0 and some of our BYODs using Windows 8 are unable to connect to the wireless. The fix for this is to upgrade the software of the WLC so that the LAPs can obtain the update to solve this problem. Simple! However, before rolling this out into the production wireless network, I would like to test it out on our second WLC which has no LAP associations, a test WLAN configured, and a newer software image loaded (7.4.100.0). I have a spare LAP that was previously associated with the master controller running the same software version (7.0.116.0). What I'm looking to do is associate this LAP to the 2nd WLC instead of the master so that I can ensure that the LAP gets the newest software. Then, I would like to test a Windows 8 device to make sure it connects.So far, I have done the following:
1. Disabled the 1st WLC from using Master Controller Mode and rebooted AP - result was unsuccessful; still associated to 1st WLC.
2. Reset LAP configuration excluding static IP info and reset AP - result was unsuccessful; still associated to 1st WLC.
3. Compared config for both WLC but since I'm new to these devices, I'm not sure what needs to be configured/changed.

I have been installing Light Weight AP's and these make LMS device discovery take much longer because they are found via CDP but do not run SNMP. So you suffer the SNMP retry and wait time for each one which adds up with several hundred AP's. I added the CDP platform description they announce via CDP to system-config.xml but this didn't do the trick. I have updated system-config.xml successfully in the past to add ATA's and 7936 conference phones and this stopped discovery from processing these devices. So I was surprised when this didn't work for LW AP's. The CDP platform of the AP's looks like this (from show cdp n):
Platform: cisco AIR-CAP3502E-A-K9 , Capabilities: Trans-Bridge
So you can see cisco is all lower case and there appears to be spaces at the end before the comma. I thought the spaces might be the problem so I added them in system-config.xml but this didn't work. When I display system-config.xml with the XML editor in IE it does not show spaces at the end even though they are their when I look at the file with notepad. When I enable debug for discovery it shows these being added to the bypass table for CDP discovery but it still tries to process them. This is LMS 3.2 on Windows Server 2003. I use the CDP module for discovery.

Recently, our company wireless AP 1262 connected more than 40+ clients, and sometimes the wireless access speed is too slow. those clients are only for MES data transfer, the date no more than 10K of each stations. So I'd like to know if the one AP can support the network traffic if whole testers transfer the data to Database via this wireless AP1262? and the WLC no clients roaming option for which clients can connect to another AP around. I have checked the WLC and AP configuration. no option for clients roaming to another APs, do you know how to configure this AP's Clients move to another APs?If we setup the new APs in the location, does the clients will be auto connect to this new AP?

We have a WLAN consisting of a WLC 4402 and 11 lightweight APs. For security/compliance reasons we have a Cisco PIX firewall that sits between the WLC (outside) and the APs (inside). The APs are allowed to form LWAPP tunnels through the firewall (inside access-list) to the WLC and the WLAN works as expected.The firewall then limits traffic from the WLAN (outside access list) to certain the internal systems.I have noticed that every so often the firewall logs show continuous "Land attack from 0.0.0.0 0.0.0.0" messages then all APs are disconnected (all lights flash).

Is the process for converting 1260 APs to lightweight mode any different from converting 1140s or 1250s? I've converted several APs to LWAP mode but this is my first 1260. Four 1260s need to be converted.I have one in a remote location that seems to be comatose. Here are the steps I took to convert the AP. Did skip/miss a step?
1. uploaded code to the AP ap3g1-rcvk9w8-tar.152-2.JB.tar
2. configured the AP for DHCP. It successfully leased a DHCP address. Controller information is provided via DHCP Option 43.
3. saved the configuration
4. verified the code, successful
5. disabled wireless radios
6. installed the lightweight code using the command archive download-sw /safe flash:/ap3g1-rcvk9w8-tar.152-2.JB.tar.The installation was successful
7. rebooted the AP
After that nothing. The AP has not leased another IP address. The switchport is active. The APs MAC address is registering in the switches MAC address table. The AP is receiveing PoE from the switch. I noticed that this AP is only receiving 6.2W of power where the three are getting anywhere between 8.8W and 9.3W. I am unable to ping the old static IP of the AP too.

One of my customers asked me to configure a WLC 2106 and 2 LAP 1131AG (lightweight) for corporate/guest Wifi. Basically they want to implement a good wifi connection for internal use and a guest one with different QoS. The two lans should both have dhcp but they must bet kept segregated so that none from the Guest wifi can access corporate resources.
Since i've never configured a WLC from scrath i lightly supposed it would be quite straigh forward as routers and switches from Cisco.Unfortunately i was totally wrong.
I've downloaded the "Cisco Wireless LAN ControllerConfiguration Guide" (Soft.Release 6.0 June 2009) and after i red it i made up this workflow
for the configurations:
1) Configure Controller: (via serial)
- Set Management Interface parameters (IP- SM - Def GW - Dhcp server IP)
- Set Ap-Manager Interface parameters
- Virtual Interface parameters
- Set Admin Credentials
- Dhcp Configuration (internal and/or external)
2) Ap registration on the controller
- Configure vlan with dhcp request redirection to the dhcp server
3) Configure Wlan following customer's requests.
- Configure Wlan Auth for Corporate/Guest Wifi
- Configure QoS for both Wlans
Unfortunately i'm experiencing issue while trying joining the AP to the WLC.It appers that the IT guy of my customer tried to configure one of the Ap.In that Ap's flash i find files referring to a "mesh" configuration like: [code]

When I tried to download software for WLC44xx, I noticed both mesh and standard software releases. Do I need to keep seperate controller for mesh APs?.
WLC with standard sw can not handle mesh APs?

We have 9 WLCs around a corporate network. Each of the WLCs was in the same mobility group for failover purposes, and to permit APs to reconnect back to their primary WLC in the event of a failover.
However one of the sites has now been sold and pending separation of the LAN infrastructure the APs need to be isolated and prevented from associating with any WLC other than their primary (on site). From our experience once the APs know about other WLCs they retain this list in NVRAM even if the secondary WLC is removed from the configuration they will still associate with one of the known APs if possible (Cisco document this). WLC v 8.1.185.

AP = AIR-LAP1131G-E-K9
WLC = WS-C3750G-24WS-S25
Total 6 floors building, 2AP on each floor.Problem Statement:- Eg: Wireless Clients from ground floor are associating with AP on the 3rd floor.This happens throughout the whole building.I would expect that ground floor clients would be connected to ground floor AP.Is there a way to force clients on specific floors to connect to their designated floor APs?A thorough check indicate that, ground floor AP is not congested and only a few clients are connected to it.

We have a Cisco 5508 controller with 1142 LWAP's running version 7.4.100.We have several Dell laptops which will not associate to the access point UNLESS you stand directly underneath it, power off the wireless, turn it back on then eventually the PC will associate to the AP.Once the PC is associated to the AP and user is authenticated then all is well.
Have tried updating the wireless drivers downloaded from both Dell or INTEL. This does not happen to all of our laptops. However, without making any changes to the WLC or the PC's, we have begun to expirence this problem with laptop which previously did not have this issue.

I have a WLC 5508 and several 1142 access points. The APs are not showing up in the WLC. When i console into the APs, im getting the following errors,
*Dec 26 23:04:28.035: %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 65.125.15.212:5246
*Dec 26 23:04:28.074: %CAPWAP-5-CHANGED: CAPWAP changed state to

Ive tried resetting the WLC, reloading the APs. I even factory defaulted one of the APs and still getting the same message.Ive verified that the WLC is set to accept MICs and SSCs.

I previously asked if I should be concerned that the Internet light on my Linksys E3000 router doesn't light up when I have Internet access. Well recently I had to do a reset and I noticed that during the reset it does in fact light up, but it doesn't come on when the router is done with the reset!

ASA 5520 running 8.0.4
ASDM v.6.1
Need assistance understanding how in ASDM/Configuration/Site-to-Site VPN/Connection Profiles/ "Any Entry" I can specify that I only want to offer an IKE Proposal of pre-share-aes-256-sha?
The IKE Proposal field has a number of possible options including: pre-share-aes-256-md5, pre-share-3des-md5, pre-share-aes-256-sha, pre-share-aes-192-sha, pre-share-3des-md5, pre-share-aes-sha and pre-share-3des-sha.
I am able to pick a specific IPSec Proposal w/o issue but when I attempt to do the same for the IKE Proposal, and click OK the choice does not "stick" but rather returns to the entire list as defined above.

Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:
class ipv4 rate-limit-port-A1
match ip 10.136.0.0/16 any
exit
policy qos port-a1-ratelimit
class servers-to-be-slowed action rate-limit kbps 1000
exit
interface A1 service-policy port-a1-ratelimit inI'm not sure about this.

how to migrate from WLC4404 to WLC5508. I want to know your propositions.
I could replicate the configuration manually but there is a lot of confirugation menus and all. If both could be online and migrate the AP to the new one until there is none on the old one, it would be great.

My customer has two SW6500 on VSS mode connected via VSL. Anyone connected WLC5508 with SW6500 VSS using LAG feature ?I wish to connect one uplink from LAG to the first switch and the second uplink to the other. The two switches are considered like one logical software.I have already read the best practice from CISCO when we connect a 5508 to a switch regarding the port-channel but nothing regarding VSS and VSL link.

Currently we have 20 remote sites, each with 2-5 AP's each. They all connect back to our Main Data Site in the US and register on a single WLC5508.
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

I'm using WLC5508 /w 7.0..My client do not get its IP. Status shown "DHCP_REQD".I found in (Cisco Live) Troubleshooting Wireless LANs with Centralized Controllers This related with Enable/Disable DHCP Proxy checkbox. I solved. with Enabling this.But,
1) Why this box have been working correctly for longtime? No one did diable/enable this feature on my box.
2) I guest, ver7.0 Disables this chechbox by default. Or not? I also have others two 7.2 boxes. Those are all Enabled.

looking at doing the site survey before detailed implementation. we plan to use a wlc5508, AP3602, a good tripod/stand, PoE switch and AirMagnet to conduct the site survey. i'm inclined to use a single AP and just a guest SSID and let AirMagnet merge the readings on where i 'locate' the AP (on 1 VLAN)

A customer have a bad coverage in a corner of his branch office. He like to add a mesh AP (MAP) in the near of that corner.
I checked allready the documention about Mesh but i'm not sure if Flexconnect and Mesh works togheter. This MAP is in a branch office and the WLC is in the head quarter therefore he likes to uses Flexconnect togheter with Mesh.

I have a customer who is going to deploy a WLC HA AP SSO setup. I have recommended them to have 4 Gigabit SFP modules in each WLC5508.The customer now asks if it is possible to only have one or two SFP modules in the standby unit ? As he says it is properly not going to go in service one time within the next five years if he is unlucky.
