Cisco Wireless :: GRE Tunnels On 4408 Controllers?
Sep 9, 2012
I have been tasked by my boss of finding out and implementing a solution of building GRE tunnels from 2 4408 Wireless controllers system for a guest wireless network. I am but a low CCNA wireless, working on getting motivated for CCNP wireless, but I didn't even know if this was possible and if it was where to begin. I have been reading configuration guides but figure I should ask the wireless experts of the world of Cisco.

we have 4408 controller purely for guest access and with local authentication..basically the guest access is free but needs an acc on the WLC on logon. when the user uses credentials to logon, after a while it gets disconencted and the user needs to reauthenticate. this happens every few mins. is there an option on the WLC to extend the session?

Our controller get freezing every week at least twice, and do not know what is the reason. I am attaching the log for you to look at it. Last time happened was yesterday at around 13.00 pm.

I am read this cisco document Cisco Catalyst 3850 Switch Services Guide
[URL]...
which describe that
L2 roam occurs when the user roams from an access point connected to its controller to a different access point connected to another controller, where the two controllers are L2 adjacent to each other.
L3 roam occurs when the user roams from an access point connected to its controller to a different access point connected to another controller, where the two controllers are L3 adjacent to each other.
so what exactly this mean the two controllers are L2/L3 adjacent to each other , what is the different between them.

I am configuring two 2504 controllers, which I ordered together, however they run different software versions and I don't have a contract/ login to download wlan controller software from the Cisco website. The one with the newest version runs 7.2.103.0 while the other one runs 7.0.220.0 I want to run them together in the same subnet and use them for redundancy (10 AP's will connect).
Is there a way I can download the software from the controller, just like I am able to do with an ASA firewall? Then I can upload it to the controller with the older software version.

I am setting up two 5508 controllers, one in HA mode, and one the primary for the remote sites in question. I plan to have these units service wireless for MPLS conected regional sites (each with their own local subnet). I was planning on using the cabled hosts network in each site for the wifi addressing and was thinking a different addressing for Guest Access, is this common? I'm obviously concerned with guest access clients but don't know enough how their trafiic is segregated from normal wifi traffic.
Also, when I stand up the controllers the management interface and ap-manager won't be in the same network as where the hosts or LWAP's will reside (routing access will exist though).

We have 2 Cisco 5508 WLCs, each wtih 50 licenses. What I would like to do is split the 50 odd APs between the 2 controllers load balancing the traffic. If a controller goes down or there is a break in the path all APs would failover to their configured secondary controller. So far so good.
However there seems to be no way to 'replicate' the configurations between controllers unless I setup HA , but as I understand it HA is Active /Passive, so essentially, unless you get a failover situaltion, completely 'redundant'.
Is there a way or either replicating between controllers automatically with out HA, or is there a way of making HA Active / Active?

I'm looking into upgrading our 4400 series controller to 5508's. Currently we have a few sites that have 8-9 4404 100AP controllers and I'm looking to condense these down to either 3 5508-500 or 5 5508-250 depending on cost. I'm wondering what a good port to AP ratio is for controllers with licenses that can handle over 100 AP's. I know the general rule of thumb is 25 AP's per port, but that seems to me to be 4400 way of thinking. I'm trying to also reduce the controllers overall footprint, i.e. ports on the uplink switch, power consumption, rack space etc.

I am planning to move our WLC's (5508) from a branch site to HQ so that all branch site APs will just report centrally in the HQ. There are two WLCs working as Active/Standby. Plan is to move one then the other. I am not really inclined with wireless.

Actually we have a 4402 controller with 1120 APs both of which are marked as EoL products, we want to jump over the new 2600 APs and 5508 Controller for increase signal coverage but we have the following deals:Last firmware for 4402 controller is 7.0.Firmware needed for 5508 to support 2600 APs is 7.3.Is it possible to configure mobility between 4402 and 5508 even with different firmware branch?

--- I have 2 WLC's 5500 that I have to set up on my network with the same configuration except I am not sure that they can be load balanced.
-- My only thought is to take a full class C and on each WLC set up a /25, thus each device can provision 120 IP's
--- This seems a bit archaeic, but is there anything else smarter to do? Can they be load balanced?

We are installing a set of 5508 controllers at one site in Tennessee. At another divisional site we have another controller that covers that division.
Both sites utilize the same DNS structure and would like to use the DNS entry CISCO- CAPWAP- CONTROLLER entry for bringing new AP onto the controllers at their sites, how would we go about configuring this?

If we have 2 Cisco 2504 series wlcs and use multicast features in both and both are primary and secondary for LAPs. what about of we use multicast ip address let's say 255.239.1.60 can we use the same ip address for the secondary controller too or we should use any other ip ?

I have 2 WLAN controllers, a 4400 series and 5500 series controller. The 4400 series has 100 seat limit on it, with 74 Access Points currently connected. The 5500 series has a 250 max, but we bought it with only 50 licenses, and it is max'd out at 50.The 5500 controller is the controller that has a DNS entry so that the Access Points will know to find that controller as they're being added. BUT, because we've reached our limit of 50 licenses, I'd like to be able to set the 4400 series controller to be the controller that new Access Points try to connect to. By going back to the 4400 as the controller that new Access Points connect to buys me time to plan for more licenses on next years budget for the 5500 controller.

Every time I power down my WLC2504 controller and then back up, the time reverts back to the year 2000.The APs can't join the controller, due to certificate errors, until I reset the clock. This problem just started recently.

Having performance issues running two 5508 controllers on the same network? One is running 7.3.101.0, the other is running 7.0.98.0. The legacy APs are connected to the WLC on the older code to support older hardware. The new WLC is accepting all the new 3600 APs. Once all legacy APs are replaced, the 5508 on old code will be disabled.

I want to download the Cisco 2500 Series Wireless Controllers Release 7.3 Software AIR-CT2500-K9-7-3-112-0.aes.I have CON-SMB for it, when I try to download it I am not to download it. I have mentioned the message given by Cisco" The category for this contract does not include the feature or the benefit for software download that you are requesting at the moment, this means that even if the contract is a support assistant (8X5XNBD) does not support the the mentioned feature for you to update the device you need, please refer to your partner directly to be able to acquired a Cisco Service Contract that supports and include the software download feature to be able to upgrade and update your device as you need."Is there any seprate contract for downloading the Software.

I've read some opinions that lowering the RTS threshold can facilitate in some noisy wireless environments. I have found how this can be done on standalone APs but cant seem to implement the change on a WLC 2112. How to do it.

Are there any plans to support the "converged wireless access mode" on the 8500 controllers ? Don't want to buy this $$$ controller to throw it away in a couple of months when 3850 switches will start appearing and require local termination...
BTW: will the 3850 ever support just plain pass-through for wireless ? The local termination is a PITA because i will need to replace my WiFi AP at the same time i replace my access switch since current AP are not supported on 3850.

I have a cisco wireless environment running NCS with a wism, two 4400's, and now two 5500's. The bulk of our AP's are 1131's, however we are now ordering and using 1142's and 3602's. We just added the 5500 controllers in preperation for a large deployment of 1142's. What I would like to do is have the system setup so that the the 1142's will default to the 5500 controllers. Since the wism and 4400 wont support the 3602's its not really an issue for them. I'm trying to find the best way to accomplish this. I've already heard one suggestion of manually going through and setting all the AP's to a primary and secondary controller but I was hoping to find a way to have the system do this for me.

Is there any way to configure a wired guest network with a combination of 5508 and 2504 wireless controllers? I am aware that the 2504 does not have wired guest functionality, however is it possible to set up a wired guest on the 5508 and using mobility anchors, transmit the l2 information through eoip to communicate with the remote vlan?Home built NAC solution, using 802.1x authentication on switchports for public areas. If user is an employee, communicates with the supplicant on their machine, and places them on an internal vlan.If user is a guest, user fails 802.1x check and is placed on a "guest" vlan with an ACL and external DNS.If placed on the guest vlan, the user has to accept a terms of use form.This is working currently with our 5508s without any issue, however we have some remote offices we'd like to roll this out to that are using 2504 controllers. I'm hoping there's a way that I can use the 5508 as an anchor or vice versa to make this work.

I have two 5508 WLCs. Both have APs attached to them. If I create a guest account with the lobby administrator on one, will that user account be able to log in to the network if the client is attached to the ohter WLC? So far, I have found that I need to create the same user on both WLC's, in order to have the user login.

Just recently upgrade our 2 5508 controllers from 6.0.199.0 to 7.0.116.0. Since that upgrade, I have a handful (8 to 10) of wireless laptops that now refuse to associate to any access points. The thing these laptops all have in common is some variation of the Intel Wifi Link AGN cards. I have about 200 other clients out there working just fine.
I've tried everything under the sun that I can think of. Patches, drivers, the whole sh'bang.
Is there a known issue with 7.0.116.0 and these particular cards?

What consequences could i have if i install a WiSM-2 module into a pair of 6500 configured in VSS and another WiSM-2 module into other pair of 6500 configured in VSS for serving a 300 APs??...in this case, do i need to configure mobility groups for guarantee a high availability and also redundancy of controllers?Under the best practices, is much better having the two WiSM-2 modules into a single pair of 6500 configured in VSS??

Do the 1042 Autonomous APs support GRE tunnels?

I'm trying to research the tunnel limits on a 5508 controller if you're terminating controllers to two different SSID's. For example. In my DMZ i have a GUEST SSID for contractors and guests and then I have another SSID used by employees so that tablet and mobile phone users can access the interenet. Because we don't trust any of these devices we have that SSID is termiated just as we do our GUEST SSID.
To reduce the number of anchor controllers I deploy, I wanted to start with one 5508 Controller. (then move up to about 3) This controller would have two SSID's, GUEST & MOBILE. On the Foreign controllers when I setup anchor tunneling I will be anchoring to the same controller however to two different SSID's.
Per the 5508 specs it supports 71 tunnels.
So my question to the group is, will the 5508 see this anchoring as one tunnel each? Or does it support 71 Tunnels per SSID?

I'm thinking about changing my home router (have WAG300N now) and my big concern are GRE and ipv6ip tunnels. Righ now I experience that every few days WAG300N stops passing GRE traffic from inside of my network therefore my ipv6ip tunnel goes down. The only way to sove that is to completly reload WAG300N router.
passing ipv6ip and GRE tunnels through E4200 or EA4500? I see no passthrough in configuration option for those routers.Also performance question - I have 64Mbit symmetric internet connection. I guess both routers would easily handle that with SPI turned on and NAT?

I have setup WCS logins to be managed by ACS 4.2 . I was looking over the docs and I appear to be missing something because I can't find any documentation on doing the same to the controllers. I did successfully lock myself out of the WiSM in the lab during some testing. I had to pull the plug on the lab ACS to allow local login.

In need to upgrade the software on two WLC 4402 controller in a hospital. Both WLCs have the same config and one is primary (has all APs connected) and the other backup (no APs connected.) The APs are placed so there is still coverage if one goes down in an area. My question - is it possible to do a rolling upgrade to have no downtime for the wireless clients? My plan would be to upgrade the backup WLC then selectively move APs to it. If I swap the primary and secondary controllers in the high availability tab on each AP, do I need to do a reset (General - Hardware Reset) or will it automatically reboot and connect to the upgraded backup controller? When I'm done, I'd upgrade the primary controller and now call that backup. Does this make sense?

We need to rename our 4404 Wireless LAN Controllers. Would like to know if renaming via the GUI (change name in the Controller / General tab and then Apply) will cause the WLC to reload. Also wondering about the best way to push the name change to the APs (High Availability) - we are not using WCS.
