Remote WLC 5508

Did any one setup an across WAN WLC as a secondary/failover one for wireless AP? Comapny has one WLC 5508 for each branch office. Management want to cost saving centralize wireless backup solution in a data center. That means if the local WLC fail, then all AP will connect/register to a WLC in data center.
Our wireless environment is a flat network with private class B network.

Hi Amjad,
I understood what Eric was trying to do, i. e., the primary controller is located locally at the site and the secondary controller is located in the DC.
I've seen this being deployed here where the site's WAN link doesn't justify the WLC to be in the DC. So that agency resorted in putting a WLC at the site. Aside from that, the client DID NOT configure a secondary controller because the WAPs are in H-REAP. If the primary controller at the site fails AND as long as the WAP doesn't reboot then there's nothing to worry about.
That's the beauty of H-REAP/Flexconnect.

WLC 5508 and remote site (DMVPN) Access Points

Hi All,
We just purchased a WLC 5508 and would like to know if it will control remote VPN site Access Points. Here are the details:
The 5508 will live at our home office. We have multiple remote sites that are connected via Cisco's DMVPN. Each site has one Cisco 1131 Access Point hanging off of either a Cisco 1841 or a 2811 that is using DMVPN back to the home office 2811. Can the 5508 manage the remote Access Points?
Thanks for your help guys!

Mapping Multiple VLANs to Multiple SSIDs as one-one in WLC 5508 via H-REAP?

Hi All,
Can anyone please show me how to map a SSID/WLAN ID to a local vlan of a LAP in WLC 5508 using H-REAP local switched? The reason of doing this is to separate Data subnet/traffic from Voice as currently all 7925 handsets using same SSID as PCs. I would like to create two VLANs on APs and map them to two SSIDs. I could not see any option in WLC5508 to do this. Also when I change the AP mode from H-REAP to local and configuring sub interface using dot1q on the interface Gi0 then unable write running-config to startup-config because I get NVRAM Verification Failed as WLC protects any local changes on any registered LAP at NVRAM.
Your help is much appreciated.

Mehdi:
I am talking about HREAP groups, not AP groups.
You can not achieve what you want if you are using the same SSID on same AP with only a WLC (same AP with same SSID is mapped to different VLANs). You may need a radius server to dynamically assign a VLAN to the clients if you are using same SSID for data and voice.
If you are using different SSIDs for voice and data, you can map each SSID to its corresponding VLAN on the remote site using the VLAN mapping option under HREAP tab in the AP config page.
You can not configure the AP from its console. Lightweight APs can only be configured from the controller. (a few exceptions are available that do not apply here) .

Anchor mobility configuration getting lost in wlc 5508 ios code 7.4.100.0

It is observed that in WLC 5508 , ios 7.4.100.0 , mobility anchor configuration on wlan is getting lost . we configure anchor ip address on guest wlan > mobility anchor > Switch IP Address (Anchor).
We have configured the template on NCS 2.0 to push the anchor mobility ip address on all WLC
Has anyone oberved this behavoiur. We have more than 100 WLC , and everyweek mobility anchor configuration is lost on some WLC having code 7.4.100.0.

I am having this exact same problem. I am running 7.3 on 5508 WLC. My remote site LAP's are using Flex (HREAP). The initial access point that my laptop associates to connects with no problem, as soon as I wander out of range of the initial LAP and into the area of another access point, I lose data connectivity. The was validated like the original post as I start a constant ping on the LAN and watch as the ping latency increases and then ping replies stop. The only way to correct the problem is resetting of the wireless adapter on the laptop. Side note my DroidX has no problem wandering from AP to AP.
Laptop: Windows 7 32bit
I then returned to my home site and test where I have a secondary controller and the LAP's are configured for local mode, no problems roaming from access point to access point. Validated with constant ping test. The pings drop for a second and re-
continues as the laptop reconnects.
**Edit: I am going to try the removing the DHCP Addr. Assignment required option, and report that back to the TAC engineer.

The problem is in deed solved by turning the "DHCP Address Required" but why?

WLC 5508 tunneling issue

Hi,
I have a WLC 5508 connected in a hub and spoke topology. The WLC is located at the hub which is the main office. In one of the remote spoke locations I have five Access Points that are connected to the local LAN and the model for the APs is AIR-CAP3602I-E-K9. The APs are all connected to access ports on the switch in vlan 1. I have two WLAN configured on the controller. I have two interfaces configured on the controller. The management and the guest interface. WLAN 1 is associated with the management interface. In the WLAN 1 advanced setting the flex local switching option is enabled. WLAN 2 is associated with the guest interface and this interface is tunneling vlan 248 the guest vlan. The problem I am having is that the devices can not communicate with each other if they are connected to the wireless connection WLAN 2 which is the tunneled vlan.
Example: The client would like to be able to connect his ipad to the apple tv for presentation. If I connect both devices to the WLAN 1 which is using flex local switching option they can communicate with no problem, but if the devices are connected to WLAN 2 the guest vlan they can't communicate with each other. Is it possible to get this to also work on WLAN 2 ?
Note: Both WLAN types are WLAN and P2P Blocking Action is set to default (disabled).
Does any one have any ideas what could be causing my issue?
Thanks in advance for your help,

Well since your talking about Apple TV, you need to look at this reference guide for Apple's bonjour. This will explain how to get it to work and the limitation when an AP is in local or FlexConnect mode. The bonjour just doesn't work as people think it should because they can get it to work with a linksys AP.

WLC 5508 and ACS server

Hi,
Apologies if this has been answered before. I did a search, but unable to find anythimg.
What I would like to do is be able to have a WLC 5508 as the local RADIUS DB and authenticator, but then be able to have an ACS server in a central location as a backup and then replicate between them.
In other words set up groups for my remote sites in the central ACS server, which then replicates only the correct group to the remote sites. This allows less adminstrative overhead, as we just update the central one.
Is this possible and how would I configure the WLC to do this ?
Thanks

Hi,
if I understood your request, you want to replicate user information between an ACS and a WLC right ?
That's impossible.
ACS can only replicate with other ACS running the same version. No other ways of synchronization exists.
Regards,
Nicolas

WLC 5508 and Multiple DHCP servers in different sites?

Hi
I work for health authority in our region and we just purchased a Cisco wlc 5508 controller along with 25 3500 AP's. We have multiple sites with different IP subnets in each, all connected by a frame relay (owned by ISP). Each site has its own DHCP server. I have the controller in our main site. So when I take an AP to a remote site, the Ap gets an DHCP address from local DHCP server (which is great) and contacts controller and joins controller. Everything is good. BUT, when a client joins at the remote site, it gets an address from a previous site which will not work because the client is now on a different subnet. We dont use Vlans as they dont transvers the frame relay. I need those clients to obtain DHCP from the local DHCP server from the site they are on. Is that possible??
I have updated the controller to latest version as well.
Thanks

We call this as HREAP LOCAL SWITCHING!! but here is the catch.. everytime the AP joins the new site.. we need to configure the VLAN mapping and this wil do it for you!! Here is the link which will resolve ur issue..

Cisco WLC 5508 with 3702APs - mobile hotspot for 2000 Guest users

Cisco WLC 5508 with 3702APs - mobile hotspot for 2000 Guest users
I've been given a fantastic "opportunity" by my boss to use our existing wireless infrastructure to provide internet access to potentially upto 2000 VIP guests arriving with BYOD devices, in a very densely populated area for a 3 day event. We are talking an area of approx 200m x 15m. Think of it as an awards ceremony/concert. The solution will also be mobile so we will be using internet breakout from different telcos as it will move to approx 20 countries. The area is also incredibly densely populated with other wifi APs. I did a brief site survey and AirMagnet could detect over 2500 other 'rogue' APs from where I was stood! I hope CleanAir works!
We need a simple authentication method for them to connect with zero admin from our side. We don't want to just offer up a rolling daily PSK as that's a bit amateur and we don't really want the VIP guests sharing the PSK with others during their stay. Ideally they could self-provision by providing an email address.
I know the WLC can handle webauth for local users but I don't think it scales very well. ie I don't think I can offer the account to several hundred people.
Cisco ISE looks a very expansive (and expensive) product but I don't think we need all it's capabilities (do I?). It would be nice to just ask a potential user for their email address and grant them access and email them next year. I've seen Cisco NAC but that looks over the top too for just guest users who will only be accessing a shared internet connection.
I've seen 3rd party supposed software solutions from Kiosk Antamedia etc do they work with Cisco Enterprise WLC solutions?
We'd like to limit users to a certain (low) bandwidth and block (say) torrent traffic to keep the general user experience worthwhile.
Does anybody have any case study documents or experience of such a project? As well as the authentication it's how well the APs will handle the dense potential number of clients trying to connect in such a confined space.
Any suggestions would be gratefully appreciated from the knowledgeable community.
Cheers,
Mike

Hi Rasika,
We are having WLC 5508 model with software version running 7.4.121.0. AP Models are AIR-CAP2602I.
Normally our WAN links are good even while the issue pertains. We are connected to remote offices over ipsec site to site vpn for WAN. The link latency in WLC between the AP and the controller shows <1ms.
currently the Guest network is using WPA2-PSK auth given in the controller. we are trying to find a option to make the Guest wireless auth local to the office, and see if this solves the problem.
any suggestions,
Thank you,
Arjun

One WLC 5508, Multiple Sites/Networks

So I'm trying to think this design out in my head. Here is what I have:
Corp Office with a WLC 5508 configured with a management port and a guest WLAN port for guest wireless etc to the corp Layer 3 switch in a wireless VLAN, using 802.1q trunk of course. The WLC is configured to be a DHCP server for the Guest WLAN.
(Side note: the sites are connected using WAN routers at each location configured with bundled T3's and all routes are setup and each network successfully traverses to the other)
First phase will be to install 30 APs. 5 at the corporate office and 25 and two other sites. I'm using a class A network but have subnetted the networks so to speak to make each site have multiple VLANs using class C networks. I want to be able to implement the WLC 5508 at the corporate office and manage the APs centrally at all locations. The APs are already configured for lightweight mode and I have successfully configured 5 of them and connected.
My question is if I install the other 25 APs at the other 2 offsite locations and connect them to the network, will it automatically contact the WLC and get a DHCP address from the Corporate WLAN DHCP even though it is at another site? Am I overlooking a step or configuration method for this type of implementation?
Thanks for all contributions!

Ok so I have configured my environment as suggested. I can see the new IP Address lease to the AP at my remote site on
the DHCP Server (Windows Server DHCP at the remote site). I can ping that IP from the Central office to the remote site however the WIreless Controller is not associating the AP at all. Although I can ping the AP from the WLC. I checked the logs and I dont see any association attempt from that IP or MACt. So here is what I have:
Central Site-
     WLC 5508 With Internal DHCP for local APs
     APs associating successfully
Remote Site
     Windows DHCP with Option 43 Configured per Cisco AP Option 43 Whitepaper
     AP 1142-Light-Weight attached to switchport (Wireless Vlan configured) and reachable via ping through all of network.
     AP obtained IP from Windows DHCP from Wireless Scope I configured successfully.
So it doesn't seem the CAPWAP tunnel was built successfully. I do have an ASA 5520 in the environment but all traffic to remote sites is wide open as I do not block any ports so CAPWAP traffic should flow well.
Mission a step?

WLC 5508, LAP1262, Security Features Design

Dears,
I am planning to get the following Hardware;
AIR-CT5508-50-K9
5508 Series Controller for up to 50 APs
AIR-LAP1262N-E-K9
802.11a/g/n Ctrlr-based AP; Ext Ant; E Reg Domain
During my design, i am considering to get the following security features.
NOTE: I don't have WCS and Mobility Services Engine (MSE).
Managing Access Points at remote/WAN office.
wIPS configuration (without WCS and MSE)
How Rouge APs will be detected and Prevented. Can Automated prevention be implemented.
Is wIPS (with WLC 5508) support to detect and prevent Rouge AP.
Is Proxy Redirection supported on WLC so that the traffic from Wireless clients will automatically be redirected to Proxy (without adding the proxy in explorers of Wireless Clients).
Unfortunatelly i dont have LAB to test these features, so please respond.......

Dear Scott,
Thanks for your detailed response. I still have confusion regarding the Point5. Find the following details;
Current Design:
All the Internet traffic (http, https) for Wired and Wireless users is forwarded to proxy server (microsoft ISA/10.1.100.1)) for internet access.
For this purpose, all users have to add proxy to their explorers.
New Design/Requirements for Wireless Guest Users:
For the Wireless Guests users to get internet, they will have to add the proxy in their Explorers.
I would like to provide them Internet Access without additing proxy in their Explorers (not to bother them with configuring their laptops).
Is it possible, if WLC can automatically redirect the Internet traffic from Guests users to proxy Server (10.1.100.1).

IPad & 3502i WAP wlc 5508 H-REAP

I have a wierd situation occouring at a new remote location.
Here is my scheme.
At my phyiscal location =WHQ
wlc 5508 (7.0.98.0)
vlan 800
ssid KWD-Guest
open authentication
wep 48bit key
(ACL restricted to internet only access)
Remote physical location = 80NY
2821 router (12.4ios) - routes and dhcp for the locations networks.
3560-48 switch - user connections and WAP connections.
3502i WAP - H-REAP back to WHQ for management and configuration.
Remote physical location = 1441NY
3825 router (12.4ios) - routes and dhcp for the locations networks.
3560-48 switch - user connections and WAP connections.
1131AG WAP - H-REAP back to WHQ for management and configuration.
Here is the issue we are running into.
At 80NY the users want to connect to the guest vlan 800 ssid KWD-Guest with iPads and smart phones (model unknown).
They can see the ssid broadcasting. Try to connect to the ssid, input the wep key. wait, wait and time out on dhcp, giving themselves a 168.x.x.x addy
From the router side, I can see the dhcp request on the correct vlan hitting the correct dhcp pool.
The router hands out a valid ip address and associates it to the correct wireless devices Mac-Address
But as I said the client times out waiting for the dhcp address.
Now the kicker here is that the very same iPad and smart phone CAN connect to the guest ssid at 1441NY which is also hosted off the same 5508 at WHQ.
The only difference I see is the WAP model and the network addresses I hand out at each location.
To the best of my ability I have double checked my router/switch and controller/WAP configurations against each site to make sure there is a mirror in place.
Any ideas?

dmantill,
Good morning and thank you for linking in the pdf.
I read it and hit several of the hyperlinks included in the pdf.
While I found the information useful and informative overall I did not really see anything that explained or covered the issue I am encountering.
I have a SR open now and the TAC engineer wants me to capture some debugs on the client mac. Once I can get the local tech onsite again we will perform the connection attempt with the debugging enabled.
FYI this is what the engineer wants to see.
Here is the information that I need to see when the problem occurs:
Disable/Disconnect the wireless client from the network – wait 1-2 mins
Open Telnet/SSH session to the WLC CLI - (Use Putty/SecureCRT with logging enabled)
type: Debug client
Turn the wireless device back on and let it authenticate/associate to the wireless network. Once the client experiences the problem, disable the debug process using the command:
debug disable-all
Filename: DebugClient.TXT

WLC 5508 in HA

Hi everyone,
I have a doubt with a scheme of WLC in HA, I hope someone can help me.
I have 6 remote sites and 2 main sites, in coming year at least 3 remote sites will be opened. Each remote site has one WLC 5508, I want to deploy HA for these ones, however I want to know if only I must put other WLC at each remote site? or exists other way in order to deploy a Cisco WLC in Main Site for working like WLC HA for every one at remote sites?
Thanks

1. That is up to you and what you need for redundancy. With that low of licensing and the cost you may just want to buy a 50 count controller and not bother with an HA SKU. (2 could fail)
2. I believe this was back when they were selling HA only SKUs, you couldn't upgrade an HA to a permanent license.
3. Yes, I mentioned that the APs will lose CAPWAP connections. There will be an outage during fail over
4. It will not, N+1 is for redundancy on one.
Some designs with smaller sites use FlexConnect with AP SSO on redundant controllers in a data center, minimizing downtime.There are some caveats though.

Converged Access Design Help (Catalyst 3850 and WLC 5508...Mobility Oracle)

Hello,
I am an engineer working with a Cisco Gold Partner in Saudi Arabia. We have a large university as our client where they are constructing a new
building and require our services to build the network infrastructure. Therefore, we are to implement the routing and switching infrastructure as
well as the Wireless solution.
At present, I have no issues in implementing the R&S infrastructure as it is very straight forward but it has implications on the deployment of
the wireless solution which I explain further below. The R&S infrastructure comprises of the typical Core, Distribution, and Access layers and we
are focusing on the local distribution and access switches with regards to the new building. The client has a converged Layer 3 network spanning
from distribution layer to core layer and they are running EIGRP for this convergence. This is not a problem and has already been implemented.
Yet, the challenge arises in deploying the WLAN infrastructure. The client already has a Cisco WLAN infrastructure in place where they have a
large number of LAPs that are registered with their controllers in the Data Center. They have two WLC 5508 where one is the Primary and the other
the Secondary. The local distribution switch to which the WLC are connected also is the gateway for the SVIs for the SSIDs that are configured on
the controllers. This means that once the packets from the AP come in to the WLC, they are tagged with the correct VLAN and sent to the directly
connected distribution switch which then routes it into the rest of the Layer 3 network. Interestingly, the WLC 5508 are running AireOS 7.6 and
support the "New Mobility" feature. The two controllers have formed a Mobility Group (MG) between each other.
Now, the new building will have two Catalyst 3850 switches installed where each one has a total of 40 AP licenses pre-installed and activated
i.e. a total of 80 APs can be supported by the two switches. A total of 67 LAPs will be deployed in the new building which can be accommodated
between the two switches and their integrated controller.
Yet, based on my understanding and research about Converged Access is that, ideally, the Catalyst 3850 will only run the Mobility Agent (MA)
feature while a central controller would provide the Mobility Controller (MC) service. unfortunately, there are not enough licenses on the
existing WLC 5508 nor can we migrate the new licenses that will facilitate such a split deployment.
This means that I would need to configure the two Catalyst 3850 as independent MC and form a MG between them. I have done this and tested this
already and the mobility is working fine. But my concern is not about getting the Catalyst 3850 to work as this is simple but rather it is
focused on creating a common Mobility Domain (MD) so that clients can roam from this new building to the rest of the campus while maintaining the
state of their connections to the WLAN infrastructure.
To make things more complicated, since the new building will have its own Layer 3 distribution switch and the Catalyst 3850 switches will connect
to this distribution switch, it means that new VLANs and SVIs need to be created for the SSIDs broadcast in the new building. This means that new
subnets need to be assigned to the SSIDs.
As such, I have the following questions:
Q1) If we create new SVIs for the SSIDs (same SSIDs names will be used in the new building as in the rest of the university campus) this means
that new subnets will be assigned to these SSIDs. Now, I believe I have two options...one is to make the new Catalyst 3850s to be in the same MG
as the existing WLC 5508 which then cater for Layer 3 client roaming or I have to treat this as a totally seperate WLAN network and follow on to
the solution as per the next question. Please advise which is a better option?
Q2) I could create separate MG i.e. the new building Catalyst 3850s can be in one MG and the existing controllers can be in another MG. I can
then have one of the existing WLC 5508 (the primary one) to run the Mobility Oracle (MO) feature so as to create a single Mobility Domain (MD).
Would this facilitate in Layer 3 client roaming and RRM for all the controllers in the same MD?
Q3) If I do create a MD, how is this accomplished in such an environment since the documentation is severely limited in this regard?
Please advise at your earliest. To assist further, I have attached a topology diagram which may aid in explaining the situation with more
clarity. If these things are clarified, I will be better able to wrap my head around the technology and in turn service my clients better.
Regards,
Amir

Hi Amir,
Q1) If we create new SVIs for the SSIDs (same SSIDs names will be used in the new building as in the rest of the university campus) this means that new subnets will be assigned to these SSIDs. Now, I believe I have two options...one is to make the new Catalyst 3850s to be in the same MG as the existing WLC 5508 which then cater for Layer 3 client roaming or I have to treat this as a totally seperate WLAN network and follow on to the solution as per the next question. Please advise which is a better option?
I would configure them in the same mobility group. Also configure same SPG for those two 3850 stacks if users are frequently roaming within these two buildings.
Q2) I could create separate MG i.e. the new building Catalyst 3850s can be in one MG and the existing controllers can be in another MG. I can then have one of the existing WLC 5508 (the primary one) to run the Mobility Oracle (MO) feature so as to create a single Mobility Domain (MD). Would this facilitate in Layer 3 client roaming and RRM for all the controllers in the same MD?
MO is not required (it is only for very large scale deployments)
Q3) If I do create a MD, how is this accomplished in such an environment since the documentation is severely limited in this regard?
Yes, documents are hard to find :(
These notes may be useful to you based on my experience. I am running IOS-XE 3.6.1 in my production.
