Q: a client has a network with 60 AP's controlled by a AIR-CT5508-50-K9 (+ L-LIC-CT5508-25A) with a redundant power supply. Can he get full redundancy by purchasing a second controller? If he purchases one, can he bring it into the network? What about the extra license for 25 extra AP's installed on the first controller?
View 4 RepliesI 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).
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 ?
View 7 Replies View RelatedI have 2 x Redundant Guest Anchor Controllers (5508) located in 2 separate Data Centers with all the management and guest user VLAN spanned between two. Everything is working fine with the Guest WiFi access except the DHCP functionality as the Controllers are acting themselves as the internal DHCP Servers.
This is how I tried to distribute :
network. 10.1.0.0/23
gateway: 10.1.1.254
Controller 1, DHCP Server pool: 10.1.0.2 - 10.1.0.254 Gw: 10.1.1.254
Controller 2, DHCP Server pool: 10.1.1.2 - 10.1.1.254 Gw: 10.1.1.254
As the user load balancing between the Anchor Controllers cannot be controlled (i.e. they are active/active), the same client sometime getting 2 different IP addresses from both the Controllers (as they do not talk to each other in terms of DHCP) hence depleting the pool addresses.
I guess one way of solving this is to just run 1 DHCP server in one of the controllers but that defeats the purpose of having N+1 Controllers. Is there a better way of doing the DHCP load balancing and having full redundancy at the same time?
When a client connecting to a specific AP (example AP01), after every 1800 sec uptime it will reconnect and join other unit AP (example AP02)Both AP physically installed distance is around 6 meters from each other. I conduct the testing where i get myself sitting in middle between these two APs.
01. If i disable settsion timeout this feature, or setting the seconds become higher value, what's the performance and security impact? Is it recomend to change the default 1800 seconds session timeout?
02. Is there anyway i can tweak on WLC controller to prevent the client after session timeout then associate with another AP. This will lead major performance impact as the client woudl possibility connect to the weak signal AP and effect on the performance.

Controller detail:
model is AIR-CT5508-K9
software version is 7.2.110.0
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.

View 4 Replies View Relatedwe do have a site where we need to deploy AIR-LAP1142N-E-K9 and AIR-LAP1242G-E-K9 APs. We have two AIR-CT5508-K9 controllers with SW version 6.0.188.0.AIR-LAP1142N-E-K9s work okay, as expected, we do not have any problems with them.However AIR-LAP1242G-E-K9s do not, there is a problem with establishing CAPWAP tunnel with the controller.The AP is seen on the controller for a while, with 0 time up-time, cannot change any settings on the AP via controller, and after a while it disapears from the controller, apears again and this repeats.
The APs and controllers are connected to the LAN campus.Controllers via two 1G links configured as Etherchannel to WS-C6506-E VSS switch with s72033-ipservicesk9_wan-z.122-33.SXI1.bin on it.APs to WS-C3750G-48PS with c3750-ipbasek9-mz.122-50.SE2.bin on it. 3750 is connected to the C6505 via two 1G links configured as Etherchannel.Below I copied the log I captured on 1242 and the controller. Highlighted ones are the ones which I think might bring a clue.
I performed some troubleshooting steps.
- As we have some other controllers available over WAN, I tested the 1242 AP with 2100, 4400 and also with the same model AIR-CT5508-K9 with SW version 6.0.188.0 over WAN and this worked always okay.
- I wanted to be sure that I eliminate any kind of out of sequence packet issue, so I brought down all redundancy L2 links so that the L2 path from the AP to the controller was only through one leg links.
- I also brought the second controller down to eliminate potential issue with having two of them up.
- The AP gets its IP from DHCP configured on the C6506 switch, I am always able to ssh to AP, so the IP connectivity does not seem to be an issue.
- I have more 1242s, all behave in the same way. I also connected them to some other 3750 switches we have in the campus, always the same.
- As this seems to be maybe a kind of ssl issue, I tried to play with controller settings, like enabling Accept... options under Security/AP Policy,but this did not work.
- I also tried to reboot the controller, no improvement.
- The APs came from the factory, so in the beginning everything was factory default in them. They were always able to download the image from the controller in the very initial phase. I still do have some of them untouched, so I can perform any troubleshooting steps with the fresh one.I can reproduce this, can also send debugging logs if needed.

I've two wlc model CT5508 version 7.0.116.0. They are working fine except for the RF grouping part. When I look at the RF Group members part in the configuration, I can see only one wlc (the one I'm connected to). If I connect to the second one, in the same part, I've just one controller (so the second one..). I tried to restart the algorithm but no change. Each controller is configured with Group Mode set to auto, and their respective role are auto-leader...I tried to change the RF group name on both wlcs, but it didn't fix the problem. When I look at the logs, there is one which appear quite often:

Now, my company is considering to implement a wIPS solution, so i planned to install in the Main Site a MSE3300 and (01) AP 3500e as a wIPS AP Monitor in the remote sites,
Need to confirm:
A) Can an AP3500 work with HREAP and as wIPS monitor AP at the same time? or in other words, if it is possible to have an AP wIPS monitor far away from the WLC (over the WAN)?
B) What are the requirements of WAN link if I want to install a Centralized MSE 330 Engine,which perform the wIPS solution in all the network.

the one for guest has web authentication, using Iphone every 2 to 3 minutes it time out and i have to reenter the credentails for web authentication.
I am running big wireless network, with 20no of 5500 with 7.0.116.0 version. I have more than 20,000 AP's. If i add some config in primary controller or do some changes or reboot all the AP's are moving to backup controller. this doesn’t have any problem, but many AP's which moved to backup controller are losing VLAN mapping. This happens every time. Primary --> backup, backup --> primary. Both controllers have same vern...same config etc..

View 15 Replies View RelatedIn 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?
