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.

which controller I should use with 11 1552E AP ? I know 5508 will work with the AP's, but would the 2504 also work? If 2504 will work, I will go for the 2504 since its a cheaper solution.

Done a wifi mesh using 1552E and 1552i mix of AP's ? With the 1552E as RAP and 1552I's as MAP's ? Is it a recommended model of deployment and will it work well ? the 1552i having radiation pattern more towards the ground when mounted on top , will the mesh backhaul to the 1552E be strong enough ?
Will this work if i put the 1552e at a lower level than the 1552i so that the mesh is formed properly ?

In our mesh network. there are 8 root AP and 15 mesh AP . we are using 1552E ,i have few questions on it:
1. If the ap's acting as mesh ap are connected with only 2.4 ghz external antenna, will they have problem joining the root access point to form mesh.
2. How should we set the channel assignments. Do we only set them in root ap's.
3. should the channels be set under 802.11a ?
4.should the channel be manually set or should it be left to be chosen dynamically.

Is Cisco WCS mandatory when deploying an outdoor enterprise mesh solution?If I am goin to use the 1552E purely as an outdoor access point ,do I really need the Cisco WCS?

I have a running Mesh Network with AP 1552E and Controller 5508. The end customer has a new requirement to have a indoor coverage near to AP1552E (mesh AP). But in this building he has not any wired Network (it is far from any switched site). The question is: We can use an AP1262 indoor with Line Of Sigth to AP1552E in the running Mesh Network? I know AP1262 can be used in a Mesh Netwok (Root or Mesh) configuring it as BRIDGE [URL]

What is the power rating of a 1552e mesh AP before the antennas are attached? I have the dual band 2.4 / 5 GHz antennas. I know their Db rating, but I have not been able to find what the AP is.

I have to build a MESH topology with 1 Root Access Point and 4 Mesh Access Points which are 1552E.I have a wireless controller which is a WiSM 2 card into a 6500 chassis.I want to know if there is a pre-configuration to do on the AP before installing it, or if they are automaticaly discovered by controller (even for MESH AP which are NOT wired to LAN) ?

A 1552E has a temperature gauge sensor connected to its power over Ethernet port. the port status shows line protocol as down.The cable from 1552 to the sensor has been changed twice. We can see the 1552E gig1 interface is at 1000full duplex. Is there any chance the speed is causing the problem here. it seems the 1552E doesn't allow to set different speed & remains on 1000.

i have a problem with 1552E to register with 5508 WLC, and always got "AAA authentication error” in the WLC log, while AAA is not enabled. so my question is , do i need to add the MAC address to the WLC MAC filter list even if i not enable the AAA server in the WLC.

I have one controller 5508 that will hold 50 LAP 1262 and another Controller that will hold another 50 outdoor mesh access point 1552. Both controllers (not redundant) are at the HQ while the access points are distributed between HQ and 3 branches.
The requirements is to have the SAME 4 SSIDs on MESH and LAP each have a security type (, wep,wpa,dot1x...) on HQ and Branches. Now, in the HQ I don't think I will face a problem since the WLCs is on the same LAN, so 5 interface v lans will be configured one for the WLCs and access point and another 4 interface v lans for the 4 SSIDs.
Now, for the remote sites I need to create another vlan on the switch with DHCP and option 43 ..... for the access point to register with the controller.
But here, do I have to create another 4 interface v lans (4 different sub nets) that should be bidden to the SSID as in the HQ?
Or the Access point will encapsulate all the traffic including the client traffic? Note that I have outdoor mesh access point and Lightweight access point and the BW link between the HQ and branch is 100M.
Also Can I have roaming between the same SSID that broadcasted on MESH and LAP knowing that each have different controller.

New to working with Wireless and the Cisco Meshing concept so have a few questions to ask.I currently have the majority of the mesh setup and configured. I have a setup with two RAPs with 9 MAPS connecting to each RAP.
First question is how many MAPS can connect to a RAP generally?Secondly how can I block other cisco AP's that are not in my mesh network from trying to connect to my AP's
The below is constantly hammering the logs for 6 devices that are Cisco close to my mesh that are not mine.

Mesh child node '58:35:d9:aa:db:4f' has changed its parent to mesh node '88:f0:77:b7:c6:e0' from mesh node '88:f0:77:b7:c6:c0'.
Mesh Node '58:35:d9:aa:db:4f' failed to join controller, MAC address not in MAC filter list.
I have only added the MAC addresses of my AP's in to my AP Policy under security. Would these other AP's affect the mesh in any way?What I am seeing is the AP's constantly changing the child to parent relationship. I have inherited this network and they have about 20 AP's all within a square mile which is absolutely overkill. Would this close proximity of AP's together be the cause for the constant child parent changes?
How close should I have RAP's together. The network was setup so two raps are about 20 metres apart and the AP's on one side connect to RAP1 and the other to RAP2?How do you deal with Radar? The install is pretty much next to an airfield with radar running and a few times I have seen all the AP's disconnect and change channels.

We had our wireless mesh network running with 4400 Controller and 1510 A.Ps. Now that we have bought new 5508 Controller (with SW: 7.2) and 3600 Indoor APs, we are unable to add legacy APs on our new controller. After a wild googling I have found that for 1510 APs i need to be on SW ver: 4.0. But that will lead into another situation i-e I wont be able to have my 3600 APs on WLAN Controller.

Currently my solution consist of two 5508 controllers and several non-mesh and few mesh AP (2600) running in flexconnect mode in one single site in europe. Everything is going fine. However there is going to be a new site in Canada. I found some documentation saying that multiple country code is not available for mesh ap. Mesh ap are not going to join controller if multiple country code configured . but all this documentation is regarding version 7.2 and older. Im running version 7.4.100.0 and on configuration guide I don't find anything related to that.

I have two number of WLC model 5508 running IOS version 7.0.98.0. 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.

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?

I am having some troubles with client roaming on a 5508 controller running firmware 7.3.101.0. 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?

I have one 5508 with Product version 6.0.199.4 and about 7 Cisco 1140 APs.We have a next problems. Go out of the connection on the clients PC, while physically a wireless connection to the workstations is not broken, but access to network resources is lost and restored after some time (up to about one minute).The logs on the controller at the same time see the following message.

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?

Is it possible to rename the default webauthentication URL from [URL] to something like [URL]. We are running on 7.0.98.0, 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.

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.

I have an environment of Cisco 5508 Wireless Controller and 1142N Access Points. I have a problem with the ratio of concentration of clients connecting to Access points in floors.
Recently I have been turning off 802.11a on the access points and I am seeing increase in client count in a few of acces points.What is the maximum client count supported by these access points and how do i ensure they are distributed evenly on access points?

Since two months they work full time with the new Dutch Electronic Patient Dossier.We installed 3 Cisco 5508 controllers, version 7.0.230.0 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 7.0.240.0. The only problem I have is the WCS. When upgrading to 7.2 and higher I need to have NCS.

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...

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.

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?

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.

User is connecting to 5508, running 7.0.116.0. 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.

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?

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.
