My customer has a 4402-25-K9 and need a backup (failover) controller to avoid data transmision break when primary controller goes down.4402 are end of sale so I have a question can I use 5508 to get Controller Failover Protection with 4402 ?

I need to install one 5508 and a 4402 together to bring redundancy to a wireless environment.Can I do this?. What are the neccesary steps to perform this?, the idea behind this is to bring redundancy is the primary WLC falls for any reason.

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?
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?

View 2 Replies View RelatedI have a facility, where all the access points almost 250 of them are connected to two WisM's (One in each core switch ) . They are running in 6.0.199 firmware . These two WisM's are managed by WCS , which is running 6.0.188.
As i need to add more access points and to make fully redundant , 5500 controller was ordered and it has with firmware 7.0 installed. Couple of queries related with it .
1. Can 5500 be added in the WLC group, so that existing Access Points can be configured to use primary controller as 5500 and secondary / tertiary controller as WISM ?
2. Will 5500 be able to be detected by WCS , as the version of 5500 is 7.0 and WCS version is 6.0.188 ?
3. As WCS was already deployed and live, is it possible to upgrade, if the client has support contract like SUSA ?
Since WLC5508 MGMT interface is configured a AP-Mgr at the same time, can I set a Backup Port to WLC5508 MGMT interface? Refer to WLC configuration Guide:
In the Backup Port text box, enter the number of the backup port assigned to the management interface. If the primary port for the management interface fails, the interface automatically moves to the backup port.
Note Do not define a backup port for an AP-manager interface. Port redundancy is not supported for AP-manager interfaces. If the AP-manager interface fails, all of the access points connected to the controller through that interface are evenly distributed among the other configured AP-manager interfaces
if I need to configure the backup port for MGMT interface, i need to remove the AP-manager on MGMT interface and create a network dynamic interface for AP-Manager ?
I just turned on 2 Wirelless LAN Controllers 5508 and I am getting this message on both of them:
Loading primary image (Image not found)
** Unable to read "linux.pri.img" from ide 0:2 **
Loading backup image (Image not found)
** Unable to read "linux.bak.img" from ide 0:2 **
And it is taking me to the BootMenu. I selected option 4 to Clear Configuration and the controller seems to restart the system but I still get the same error. I checked the LEDs status and Sys is Amber and Alarm is OFF which according to the documentation is a System Crash.
We are deploying two 5508 WLC running 7.2 ios. Is it possible to anchor these to a 4402 running 7.0.116.0. Is there any version mismatch issues. We can find documents on the older compatibility but not on the new code.
View 9 Replies View RelatedWe 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?

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 two 5508 WLC's setup to run about 200 AP's as the moment. This is a hospital with patient care now running over wireless. I am looking for the best scenario to minimize down time. Currently both controllers are in the same mobility group and I will be setting the primary / secondary controller in the High Availability tab for each AP. Most setting are all default still.
My question:
Would it better to setup the primary/secondary from the global configuration?
Can I leave them in the same mobility group if I use the global configuration?
My only problem so far is having AP's on different controllers caused some response delay as clients move from one controller to the other. I need to find the best possible response time with the lowest possible fail-over time. Any recommondeations or links to a good article on this subject?
On a WLC 5508 it lists an option to specify a "Backup Port" under the physical information section on an interface. We have two central switched SSID's which are connected to an internal firewall. We are looking at installing a backup/standby firewall and running a virtual firewall between them. Each SSID would have an additional patch from the WLC to the standby firewall.
Does the backup interface port function on the WLC allow traffic to be failed over from a centrally switched SSID via backup interfaces to an alternative device? If this does work will only physical link failure to the primary firewall cause the backup port to be activated or is there configuration parameters which can be specified for load, packet loss or latency which can be used as criteria to cause the backup port to be utilized?
I recently tested the process for a customer of defaulting a Cisco WLC to factory configuration and then restoring the configuration from Cisco NCS. It was not seamless to say the least and I wonder if I have just gone about it the wrong way.
Have have set the NCS platform to configuration sync with the 5508 controllers at 04:00 every day and prior to the controller defaulting I ensured that NCS also reported that the config was in sync. I have also set NCS to complete a tftp backup of the controller every night 23:00 - interestingly though I have no idea where this is stored on the NCS platform ( a VM appliance ) or what it's file name is.
Anyway my experiences where as follows:-
1. defaulted WLC and via serial CLI ended up at the configuration wizard.
2. Set the correct LAG, management IP, host name that NCS knew this controller by.
3. To test things just created a dummy WLAN ( SSID ) as I assumed this would be overwritten ( big mistake ! ).
At this point I connected the controller to the network and tried to restore the configuration from the config sync version.
First problem - you have to remember to set up the SNMP community string you were using as it is needed by the configuration sync process. After adding this to the controller I could push the configuration to the controller.
Second problem - failed to add the first WLAN from the backup as I have added the temporary dummy W LAN via the wizard and NCS reported a conflict. So had to delete WLAN ID 1 from the WLC GUI directly and then the config push no longer reported this error.
Third problem - for some reason did not add the TACACS server details - reported the error that it could not added them. I manually added these via a template via NCS and all was well.
Fourth problem - all but the first WLAN was in the disabled state - had to re-enable all of the WLANs.
Fifth problem - any default items I had disabled or removed have not been saved - therefore I have removed the public and private SNMP communities - but these were still on the WLC after the restore. I have disabled unused ports not in the LAG as they show an error in NCS - these where not disabled after the restore.
So all in all not a very satisfactory restore process from NCS to an defaulted WLC ( meant to simulate to the customer what would be needed if they had to replace a controller due to hardware failure ).
I have 2 4402 WLC's and am in the process of deploying 1042 APs out to sites. But The AP's wont recognize the WLC. I have configured the DNS for CAPWAP but still no dice. I have had to serial into each unit and give it a static IP and then I can see it on the WLC. Shoulsnt this be automatic?
