Cisco Wireless :: 5508 - Client Not Receiving The IP?

Apr 12, 2011

I have two number of WLC model 5508 running IOS version And One WLC in DMZ with the same model and IOS version. AP model is 1141. The Two WLCs are integrated with ACS. I have a SSID named EMployee. The DHCP for the users are configured in a seperate DHCP server and i have mapped this DHCP server IP to the interaface Employee.And this interface is mapped to the SSID as well..  But my client is not receiving the DHCP IP. Attached are the debug logs from the client.

Cisco Wireless :: 5508 - Lightweight APs Not Receiving IP Address Following Controller Upgrade?

Apr 3, 2013

I have a 5508 controller, just upgraded from 6.0.182 to Also LAG was switched off directly after upgrade.
Since the upgrade none of the 1142 LAPs are associating with the controller. I can see they are being issued IPs by the internal DHCP but putting a console cable and watching I am getting:
Not in Bound state.
*May  4 11:41:17.759: %CAPWAP-3-ERRORLOG: Not sending discovery request AP does not have an Ip !!
*May  4 11:41:17.759: %CAPWAP-5-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP.             
One Ap prior to the upgrade was on a static IP and that connected through without any problem, (it was an 1131 though, but I dont think that is the issue...)

Cisco Wireless :: 5508 Duplicate Client IP Address

Dec 1, 2012

I am using 2 anchor controllers 5508 as DHCP server. Anchor controller A is primary and anchor controller B is secondary. From time to time, client will complain "duplicate IP address error" when they try to connect guest wireless.First question: both anchor controller should have a recorder of IP address which is assigned to each PC, right?Second question: is there any way this type of issue can be avoided?

Cisco Wireless :: Client Roaming With 5508 Controller

May 27, 2013

I am having some troubles with client roaming on a 5508 controller running firmware As soon as a client roams outside the range of an AP they lose data flow and do not seem to transition to another AP for about 1 minute.This is a small network with 6 x AIRCAP3502E-N-K9 AP's (running in H-REAP mode) on the same floor and clients are a mix of HP notebooks, Mac Books, iMacs, iPads and iPhones. There are several seperate SSID's setup and the problem occurs on all. All are WPA2/AES with either a PSK or 802.1X. Both 2.4GHz and 5GHz radios are enabled with auto power and channel selection.
I have tried changing the roaming settings from default and also playing with the AP power settings to no avail.Is this normal behaviour or is there something I can do to improve the reconnection speed?

Cisco Wireless :: 5508 Client Gateway Setup

Dec 1, 2012

I've just installed a standard Cisco wireless install (5508, 3502i, local and flexconnect setups) all working swimmingly.
The customer has asked for a new WLAN for a particular group of staff that will route to a different gateway than the general wireless staff.
The 5508 is connected to a older Avaya L3 switch that is the customers core swtich, but it isn't capable of PBR so it routes on desitnation only and its default route is not where I need the new WLAN traffic to route to. An ASA will be connected to the Avaya switch (which is the alternate gateway I need to get the new WLAN users to). So my question is probably routing 101, but if the ASA interface, the Avaya swtich and the WLAN interface all reside in the same VLAN, can I give the wireless clients the ASA as their gateway via DHCP and successfully get their traffic to the ASA?

Cisco Wireless :: 5508 WLC - Associate Client From AP If Idle For Certain Time

Sep 16, 2012

Is it possible to rename the default webauthentication URL from [URL] to something like [URL]. We are running on, is it possible to do http for web authentication and https for Mgmt access if we upgrade the controller software?
We configured our guest wireless with no layer 2 authetication so users can associate with an AP and get an ip adress but they can't go anywhere unless they have a valid username and password(web authentication) - does this affect the performance of an AP since there will be many people associated with each AP, is there any setting in the WLC to de associate a client from an AP  if its idle for certain time.

Cisco Wireless :: 5508 Max EAPOL-key M5 Retransmissions Exceeded For Client

Feb 21, 2012

I have had several complaints from around the firm where by mobile devices are being bumped off the PSK secured network (All other SSID networks are operating A-OK). Both Android and iPhone devices are being affected, the device will just loop until it reconnects, sometimes up to 20 minutes of trying to establish a connection. It will eventually connect so the key is not the issue.I've attached a debug of a device which fails to connect and then shortly after is successful.

Cisco Wireless :: Roaming With Broadcom Thin Client On 5508

Jun 3, 2013

Since two months they work full time with the new Dutch Electronic Patient Dossier.We installed 3 Cisco 5508 controllers, version last year on a HP-switched network on a layer 2 mobility domain.Cisco 1041 AP are
The personnel works woth thin clients url... The one with the double antenna.This client has a Broadcom BCM943228HM4L 802.11 a.b.g.n (2x2) adapter.
On the client they have a connected RDP session to a server with the documents.Now they are walking from one patient to another patient. The problem they experience is a very late roaming. At the beginning of the corridor, the client will associate, but is going to roam at the end of the corridor. We installed 4 AP's on each corridor, so they signal is very well, maybe to well?
I disabled client loadbalancing and band select.The lowest data rates are also disabled. Mandatory begins at 12 Mbps. I can increase this to 18 Mbps.These clients work with PSK, with both methods (WPA-TKIP and WPA2-AES) enabled.We did this because of many old and new clients.
The customer tried to find out the problem with a smartphone, same issue. Very late roaming.I can upgrade the WLC to The only problem I have is the WCS. When upgrading to 7.2 and higher I need to have NCS.

Cisco Wireless :: WLC 5508 - Client Don't Receives IP Through Mesh (1552E)

Jan 31, 2013

recently I installed  WLC 5508 en the central office and installed a network mesh in a remote office; central and remote office is connected with serial link as WAN, and I have dhcp server in the remote office for give ip address to all users and devices in the remote office. Additional I have 5 LAP1552 (mesh) and 2 LAP1260 in the remote office, all clients that connect to LAP1260(this don't belong to the mesh) receive ip address from dhcp server, but neither client that try to connect to the mesh (LAP1552) receive ip address from dhcp server. I don't have if I doing some thing bad. The range IP that receive the all ap's belong to the network of devices and the range ip for the users belong to network of users.

Cisco Wireless :: WLC 5508 Centrally Switched Client Errors

Aug 16, 2012

I am having trouble with a newly configured install.  Basically it seems that my centrally switched guest SSID is not functioning.  As you change AP groups, which should change the interface associated with the SSID and also the dhcp client address, the client is retaining the original dhcp address from whichever AP group they first associated with. 
I also have a locally switch WPA2 SSID at each location which is working fine.  Clients are able to change dhcp address correctly as they move between AP groups.  It just doesn't seem to be working on the guest network, which is odd because it was working earlier in the install.  It has only started having issues yesterday afternoon. 
The interface above is assigned to the guest SSID in one of the AP group.  I assume this has something to do with it but I've been over my DHCP assignments on the core switch, local switch, controller, and dhcp server and can find no issue with the configuration..
 I am not sure why as I am not using DOT1X at all.  The guest is a pass-thru and the WPA2 network is just WPA + WPA2 with TKIP and AES.  No DOT1X anywhere on the controller...

Cisco Wireless :: 5508 - Client Unable To Stay Connected

Jun 26, 2012

Background: Wireless credit card machines can't stay connected to the 5508 controller 7.0.116 / 1142 ap wireless system. MAC address of one of the wireless hosts is 00:12:0e:ec:ce:97. AP servicing them is d4:a0:2a:99:34:60. Hosts are able to connect to the network after a reboot and stay connected for random periods of time but then don't come back unless you manually reload them. I have 3 in total in the same room services by the same ap.

I have the output of debug client 00:12:0e:ec:ce:97. Output showed 802.1x 'timeoutEvt' Timer expired for station 00:12:0e:ec:ce:97 so I increased the value to 4000ms on the controller but am still having the issue.

Note that the output below is the state the client stays in after receiving the timeout (802.1x 'timeoutEvt') showing subsequent attampts. The only way to get them back on is a reload of the credit card machine.

Cisco Wireless :: 5508 WLC Excessive Client Authentication Association Failure

Jan 29, 2013

I have been noticing in my trap logs that there are an excessive amount of Client Association/Authentication Failures. I cannot figure out why. I have a Cisco 5508 WLC with 81 AP's (1131ag, 1142abgn, 1262N) models. The wireless devices are on a Windows Domain and use 802.1x EAP authentication, authenticating the user and computer info with a RADIUS Server. I look at the logs and all it can tell me is Reason:Unspecified ReasonCode:1. I read that the Reason Code is due to "Client associated but no longer authorized" but to be honest I am not sure what that means.

We use WLC 5508 with 7.4. We tried to set max allowed clients per AP radio to 30 through GUI. We have APs with 80 clients associeted though.
When entering config wlan max-associated-clients max-clients wlan-id we got 
"WLAN/Guest-Lan/remote-lan is enabled. disable to configure max associated clients."
GUI doesn't show that message, should it?  In GUI, Is it necesary to disable WLAN before too?

Cisco Wireless :: New 5508 WLC And 3602i Access Points / Client De-authentication

Jan 25, 2013

Installed a new 5508 WLC last week, and finished bringing 68 new 3602i access points online in our College Dorms. We are seeing a lot of "Client De-authenticated" errors "Reason: Unspecified Reason: Code 1. Years ago I asked about error code 1. The reply from Cisco was: "The programers put the code in. It basically means we don't know what the problem is."Got a call from one of the dorms stating that students were getting knocked off the network while going to sites. If a student is wired, network is solid.Walked the dorm in question and was getting full bars of signals at all times, and was able to stream a movie from my Ultraviolet account without any break or slowdown as I moved from access point to access point. So.. my device, an iPad, was fully mobile and did not experience any disconnects.Did observe one student using a MacBook Pro. This student was constantly loosing connection to the access point. Checked the controller for the MAC of the student's computer. I did find deauthentication errors. BUT... this student's error was the computer was receiving an IP address from the DHCP that was already in use. At the computer the error message was a timeout issue.I am just learning the ropes on the 5508. Have used 3 4404s for the past six years.

Cisco Wireless :: 5508 Client Stuck In DHCP Required State

Aug 31, 2011

User is connecting to 5508, running  Previously worked on another AP.  TV (client) is set to use dhcp.  As other posts have mentioned, "DHCP Addr. Assignment" checkbox is not checked for this wlan, but I also switched it to Required for this wlan but it did not make any difference.  Seems to be a problem with just this client as many other clients are on this AP with no problems.
Users have to register their MAC to get on our wireless system, but there is no encyption or security enabled once the device has been registered.

Cisco Wireless :: 5508 - Client Authentication Fails For Wrong EAP-type

Jan 16, 2012

I have setup the WLC to authenticate to a MS Server2008 NPS for a WPA2/AES SSID. The connection is successful, but client authentication fails for wrong EAP-type. I believe this indicates a Windows7 client issue. What is the required client setup to satisfy the MS NPS?

Cisco :: WLC 5508 - Wireless Client Gets Random And Temp Invalid IP After Being Connected

Jun 24, 2011

I've got a setup like this:

WLC 5508 v7.0.98
6-7 Autonomous upgraded to lightweight APs - 2 * 1231G while the rest are 1242AG
3 dynamic interfaces, 2 to Corp (diff VLANs) and 1 to Guest
4 WLANs binded to different interfaces
2 to the Corp interface Vlan X
1 to Guest
1 to Corp Vlan Y

DHCP for Corp is provided by their own Win DHCP server while controller is the DHCP server for Guest. Lease time is 1 day.
My problem now is, some clients, at random, loses their IP after being connected to the network. They get a 169.254.x.x. They connect to the Corp network OK, no browsing issues but after a while, they lose their IP address.
They can either wait for a while before getting an IP back or just simple renew their IP on their machine.
I've tried increasing the threshold values in the Local EAP to double its default values and also setting the WLAN session time out values to infinite. However, these 2 didn't work. I'm still having clients that occasionally lose their IPs at random.
I've also noted that this affects clients with WZC wireless drivers and not others e.g. Intel Proset.

Cisco Wireless :: 5508 - Limit Data Rate For Specific Client

Sep 12, 2012

I would like to be able to allow a specific client to only associate at 6mbit/s -is this possible using the wlc controller 5508? Another option would be to limit a whole w lan ssid to 6mbit/s but i can't find a way to do that either.
Other w lan ssid's on the same access points/controller need full data rates, so i guess i can't use the RF-profiling for this.

Cisco Wireless :: WLC 5508 With 3600 And 2600 AP - Client Down / Session Timer Is Turned Off

Apr 9, 2013

I have a strange issue with clients connected to a WiFi network.I have configured AP in FlexConnect mode and 2 SSID's. After a reboot of the AP the network is stable for almost 45 mins. Then each client will go UP and Down, mostly with a delay of 5 mins.
What could be the source of this. The clients are Windows CE handheld with fixed IP adres. I already configure persitent client and have play arround with APR timers as well. Thereby an Windows desktop or an iPad has less connectivity issues but even they expert pakcteloss once in severall minutes.
Session timer is turned off
The iPad for example can play music, but each 5 mins you hear a little hickup and 2 subsecond ping are loss.

Cisco :: 5508 Controllers Not Redirecting Client Requests To ISE

Jun 5, 2013

Please find attached a simple BYOD/ISE document I uploaded to kick start my new Wireless setup. Its all configured on my ISE sever and Controller as per doc.My setup:
-3600 AP's
-Internal 5508 Controller
-DMZ 5508 Controller (acts as a DHCP server for wireless clients)
Controllers have established connectivity (mobility acnhors), as a client I can connect fine to my new SSID get a DHCP IP address back from DMZ WLC and at the moment can connect out to the Internet fine (using no WLAN Security as a test). So this part is working.I have now followed the document configured ISE, enabled AAA on the Internal WLC only and used the AAA override setting on WLAN as in the attached document.I connect to SSID expecting to be redirected to my ISE Guest Portal, nothing happens other than connecting to Internet WebPages.My question is, if I have followed this document correctly why is the Internal WLC not redirecting client requests to ISE, is this because my mobility anchors need to be re-configured, perhaps the AAA/ISE config needs to be applied to my DMZ WLC not internal WLC?
I would prefer the Internal WLC to redirect the login to ISE, doesn't make sense to traverse through the DMZ Firewall onto DMZ WLC back into the Internal Network again to the ISE to authenticate.Or am I missing something additionally to this document to make sure clients are directed to the ISE Guest portal login.

Cisco :: 5508 - Client Isolation And The Bonjour Gateway On WLC 7.4.1?

Mar 4, 2013

I am considering upgrading our 5508 WLCs to version 7.4.1 to take advantage of the Bonjour gateway. What I want to do is allow clients on our guest wireless network to access things like the Apple TV in our conference rooms. My intention would be to have the Apple TVs on a separate vlan. Obviously, the Bonjour gateway would allow for access between these 2 networks. The question I have is this. If I have client isolation turned on my guest wireless network, is it still possible for these devices to access Apple TVs on another network?

Cisco :: 5508 VLAN Select - DHCP Leases On Each Scope For Same Client

Sep 11, 2011

The 5508 is running code  I have created a group interface for 3 subnets and assigned the group to the WLAN.  Clients are getting IP addresses in a round robin fashion.  The issue or downside to this is if the lease has not expired before the next time the station connects to the WLAN it consumes an address on another subnet instead of grabbing the unexpired lease IP address on it's previous VLAN.  It seems that the WLC determines the VLAN in the interface group before the DHCP request from the client in case the client already received a DHCP address that has not expired.  This can be problematic since we have seen some iPhones requesting an address every 20 minutes thus consuming an address on every subnet in the interface group.  Other than setting a lease time extremely low what can be done to address this?

Cat5 From Computer Receiving Wireless Signal?

Jul 18, 2011

I have a computer that is directly connected to my internet broadband service via my router and modem. From that computer, by use of a router (of course), I have a wireless connection to another desktop computer in my home, about 90 feet away.From that remote wireless internet broadband connection, I'd like to connect to yet a third computer. That third computer will be 200 more feet away. I have a direct Cat5 wire from the wireless computer desktop to that point 200 feet away. I'm thinking of adding a computer at that point.So, that raises my question: Can a computer receiving a wireless signal, then relay or transmit that signal to another computer that is "hard wired" to it via a Cat5 wire?
