We have 2 WLCs, 4402 (main) and 5508 (backup). While we turn on both devices, 4402 have 10 APs, and 5508 have 10 APs as well. Total connected clients will be 120+, but when we turn off either 1 wlc, let's say only 4402 is power on, total 20 APs joined, but the total client will be 90+, never reach over 100 clients. The same happened on 5508, is there any maximum associated connection on WLC?

which is the maximum number of simultaneous wired guest clients on a 5508? And in a 2112 controller?
Wired clients count as wireless clients??
What about anchoring limitations, what is the effect of wired guest clients on the anchor controller?
We are expanding our wireless infrastructure by adding further access points AIR-AP1242AG-E-K9.We use four WLC 4402 running version 6.0.188.0 as a fail over pair.What is the maximum limit the WLC can handle ?What is the recommended limit one WLC can handle ?We can divide the load on the controllers but in case of a failover one WLC will manage all access points.

I've tried enabling and disabling dhcp proxy, and using a remote dhcp server as well as the internal server. This same config works on the 4402 we're replacing with version 5.2.193 on it.

Recently (within the past 2 months) I've been having some issues with my 4402 wLAN controller.
The issue is thus:
1) New wireless clients (those without exsisting DHCP leases) are unable to properly connect to our wireless network.
2) Those same systems (and other systems) have no issue getting online via a wired connection (where available).
3) Devices like iPad, tablets, laptops partially connect but do not get a valid IP address.
Our config:
1) DHCP is handled by a seperate server (NOT the 4402 - it's DHCP setting is disabled)
2) Our wLan is not on a seperate network than our wired LAN
3) Wireless devices attempting to connect include iPads and laptops mostly.
4) We're a school with about 300 systems (primarily Windows XP machines).
5) 25 access points controlled by the 4402 (our only wLAN controller)
Important Notes:
1) No configuration changes have been made to DHCP or the 4402 device in a couple years.
2) 4402 Software Version = 4.0.217.0
The problem first showed up a bit over a month ago. I first thought the issue was DHCP server related , so I started there and didn't find any obvious issues. I did restart the DHCP server (which at that point had an uptime of somewhere over 700 days).
I then also checked the web interface of the 4402 to see what it was reporting. I noticed a somthing:A) As shown in the "WLAN_Issue_EDIT.png" the client count on the controller is showing 628 current clients. We don't have many devices in our entire campus.
I rebooted the controller after hours and that seemed to allievete the issue. Since then, the current client count hasn't ever gone above 60.
Now today I'm having the same issue regarding new clients getting IP addresses. The client count isn't real high on the WLAN controller and I don't see any other obvious issues. I'm torn between this being a DHCP issue or the controller issue (or a combination of the two).
The reason I don't think it's directly DHCP related is that all wired clients seem to be getting address fine.Plus, I've set my tablet device to a static address and it still cannot connect via wifi.
**Update** I've now rebooted the controller and the problem persists (at least on the nearby iPad - Will confirm other devices shortly).
I have 1242AG. how many clients can be connected to this AP??

The Managment and AP-manger interfaces are on vlan 6 [code] I have a 1142N AP also connected to the switch and it pulls a DHCP IP Address and configs etc and registers to the WLC. It too is on Vlan 6 and it is connected to the 4506 on int gig 4/33 which is an access port. [code] I am doing local authentication, so i have added users to the WLC.. My problem is that the first client that connected was able to get an IP address and connect to anything internal and external.I then connected another client on another laptop and that client could connect but not get an IP address, it just self assigned.When i look at the clients i can see the MAC address of both Clients on the WLC, but doing a show mac address-table dynamic i only see the MAC of the client that works properly. The client that doesnt get an IP has no entry in the 4506 switch.I am stumped, from what I understand, is that the 2nd clients traffic is being trunked to the WLC , hence it has the MAC address. But I dont know why its not getting a DHCP assigned IP address.

View 36 Replies View RelatedJust loaded the 7.2.103.0 software onto the brand new WiSM2. Going throught the options and have found that under the global parameters for 802.11a/n, 802.11b/g/n radios is now the "Maximum Allowed Clients" option. The allowed setting is from 1 - 200 clients.
Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
Doesn't seems to make sense... I have the 500 AP license on this WiSM2... I know this option used to be an optional setting under a WLAN in previous releases.
I have a few sites using the RV042 with wireless access points and some of them have over 50 devices.In reviewing the documentation (specifically,[URL]), I came across this:Enable DHCP server: Check the box to allow the router to dynamically assign IP addresses to up to 50 connected devices. Uncheck the box if you have another DHCP server on the network or you want to configure static IP addresses for your network devices.Is this accurate? Or will the RV042 allow more than 50 devices?

I have a wrt54gt running firmware 1.0.04 in my house. I have about 30-40 wifi devices.. Mostly smartphones connecting to the router. If i look at the dhcp table there is about 35 computers listed. The router is running on channel 2.
Lately ive noticed that certain devices can not connect after they are powered up.. It could be a tablet, pc or smartphone. Most will error out saying they cant connect. If i turn off a working device then the newly powered on device can connect. It seems like i have reached a limit.
Setting a failing device to static ip does not work, the device never succesfully associates. I tried upping the dhcp pool to 100 from 50. Is this just a limitation of the router? Is there another router that i can buy that will work for me?
We have a controlled setup comprising of a 4402 WLC in our Data Centre and 1242AG LWAPs in our branches.The Wireless works well with a mixture of locally switched (h-reap) and centrally switched WLANs.I have a problem where Android devices don't seem to function as they should.I have been using an Android phone (HTC Desire, currently running 2.3.4 OS, but has been a persistant issue since 2.1) and it connects to my home wireless (and others) fine, but when connecting to the Wireless LAN at the office, it connects fine and gets assigned an IP address, but NO data flows. None, like there is no connection at all. I have just been using it on 3G. I figured it might have just been an issue with the hardware, so didn't bother too much.I have just purchase a new tablet (ASUS Transformer, Currently running 3.1 OS) and this does the same thing.I have tried publishing a new WLAN and have tried all types of encryption and authentication al the way down to open and still, no data flow. I have tried statically setting the IP details and still nothing.Interestingly, When I attended the last Cisco Live conference in Melbourne this year, I had my phone and it displayed the same behaviour on the Cisco supplied wireless, BUT, there was a second IPv6 enabled, when connected to that everything worked fine.

View 7 Replies View RelatedI am running 5508 wireless controllers. I pass along another agency's WLAN across my wireless network that is anchored to their older 4402 controller.
I wish to run the new 3600 series APs and am planning on migrating to NCS and the new 7.2 code.
I know that the older 4400 series controllers will not handle the newer 7.1 or 7.2 code. However, i still wish to maintain this anchor relatiosnhip with the older 4402 controller. I need to know if this will work or not.
I'd like to replace my 4402 Wireless controller with a new 5508. I have migrated the exact configuration from my 4404 controller to the 5508 and they are both running the same version of code. I'm worried that if I replace the 4402 with the 5508 controller, the Access Points will not rejoin to the new controller or they will join but will have lost their configuration e.g. AP Name/location etc etc. AP models registered to the existing controller are 1131, 1142 and 3502. I am also using Cisco WCS.
As long as the new controller has the exact same configuration, is it possible to replace the 4404 with the 5508? Will the existing Access Points join the new controller? Is there any other configuration required? I have read about doing this using mobility groups however would rather not if possible.
We currently run six 4402 Wireless lan controllers - these are managed by a WCS server - soon to be replaced by Cisco Prime. We run a mixture of LAP1242 and LAP1142 wireless access points. I need to add more but have been told by my supplier that the both these AP's are now end of sale and cannot be purchased.
The replacement AP's are the 2600 series - but I have been told that these are not compatible with my existing 4402 controllers.
To make matters worse I was then advised that if I purchase the new 5580 controllers the older LAP1242 access points will not work with it and require replacing - this, for me, is a lot of access points.
What I need to know is:
What access points, if any, are currently available that are compatible with my 4402 controllers and a future 5508 installation?
I ssem to be in a situation now where I cannot buy any access points that will work with my 4402's but if I upgrade all my current 1242's will not funtion with the new 5508 controller!
We have got a WLC 4402 as an anchor that provides guest internet access to our visitors. Our wan sites have 4402's running a tunnel to this anchor for guest traffic. We have got a new site coming up that will have a 5508 as its WLC. I am trying to determine if the 5508 will successfully form a tunnel with the existing 4402 anchor. I am assuming that it will be ok or maybe the 4402 will require an ios upgrade. Our AP's everywhere are 1131's but the new site will have the later versions which can work with the CAPWAP based 5508.
will the tunnel between the 4402 and 5508 work well or will it require an ios + bootstrap upgrade on the 4402 and subsequently the rest of the 4402's or it will not work altogetherwill the CAPWAP AP's at the new site work well with the 4402 LWAPP anchor - I am assuming that they will since the CAPWAP compatibility requirements are really between the AP and its local WLC. Our 4402's are on 4.2.61.0 and I am proposing to management that we should upgrade these to 7.0.116.0 to prepare the infrastructure for any potential issues.
My client has on cisco 4402 controller running with 48 AP on this. Client requires to add another 25 AP but licence on the current controller is not supported client bought another controller 5508 with 25 AP.
I have been tasked to installe 5508 with conjestion of 4402. I have make the software version on both of them as below
AIR-CT5500-K9-7-0-235-3.aes
AIR-WLC4400-K9-7-0-235-3.aes
To match the same IOS version on both the controller. I have following challenges with me.
- 5508 will registered 25 AP while .. 4408 will continue with 48 AP.
- 5508 is going to be in DC and it will be directly connected to firewall as default gateway for guest SSID. 4402 is going to be on another building.
- How can I make sure that Users connected to AP registered with 4402 will have the same deafult gateway as 5508. Thre is no layer 2 connectivity between this two controllers.
- There is no romaing going to happen between this two controller as both are two different locations and user will leave one location will disconnect and it joines bak when it reach to another controller.
- Is there any way to configure 5508 as master and 4402 as slave kind of connections?

View 4 Replies View RelatedI have attached a diagram of the current topology. At present, we have two 5508 connected to our core. We also have a 4402 behind the firewall (DMZ) just purely for guest access. So the staff users connect to the access point which in turns connects to the Staff WLC 1 (if this fails then to Staff WLC2). any guest user connect to the access point which in turn connects to Staff WLC which anchors to Guest WLC which then provides access. Since the guest is behind the DMZ they can only access the internet and not out internal network.
Now we want to office extend our network - we want our users to use 1132 AP at home to access the Infrastructure. is there a way we can do this without disturbing the existing infrastructure. On reading Cisco website, i know the best practice is to use 2 5508 (one behind the firewall and the other anchored to this access the internet network ) i thought since we have a Cisco (dmz) switch (48 port) and only the 4402 (Guest WLC) is connected to it, maybe purchase another 5508 WLC and connect to the 48 port Cisco (dmz) switch. will this work?
I have an issue with two wlc 5508 in the same mobility group. We use TACACS to authenticate admins, with maximum privileges.
When I want to configure cleanair, or some security functions (such as ACL, or password policies), I have an error message saying that my privileges are not enough.When I use local account, it works well.
At the begining, I thought it was a TACACS issue, but I have the same problem with WCS and SNMP. Cleanair doesn't appears in config menu, and I have an error message for security function.
I have 10 Access-Point model 1131 AG are new AP.
When I connect the access-Point to the network, the AP associate only one time but i go to wireless for see the AP, i can see downloading of IOS, but the ios is 3.0.59, the ap don not nothing. I can not change any parameters.
We currently have all of our foreign AP controllers on software version 7.0.116. This consists of a mixture of 4400 and 5508 WLC's. Our guest anchor is a 4402 on version 7.0.116. We are replacing the guest anchor with a 5508. We are also upgrading our 5508 wireless controllers to version 7.2 to support the 3600 series AP's. My question is what is the recommeded code that the anchor controller should be on? Should it also be upgraded to 7.2? If we upgrade the anchor controller to version 7.2, will this affect anchoring to 4400 series foreign controllers still on7.0.116?
