5508 and 4402 Controller Anchoring?

Hello,
I 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.
Surely someone else has encountered this?
Thanks,
Phill

Sent this one to TAC... they said it should work fine.
I am planning a large deployment that depends heavily on the 3600 series AP...
Not anchoring with older controllers would be a show stopper..or at least bring the project to a crawl...
I'm already trying to figure out a workaround for surveying with the 3600 AP when i cant even run it.
(7.1, and 7.2 will not work with WCS...I already tried running it and it broke my ability create guest accounts...I was impressed with the 3600 AP though...).
I have to wait until I can get NCS purchased to migrate to the 7.2 code
Not looking for anymore surprises....

Anchor mobility between WLC 5508 and Aruba/Clearpass

Hello. I have a question regarding the abiltiy to configure anchor mobility between a 5508 WLC and an Aruba controller. To date, my understanding is it has never been possible and I have never found any documentation that says it can be done.
Scenario: My organization and a partner organization co-own a hospital. We coexist on a large campus, with each org having a number of buildings that the owning org maintains the network presence in. We also maintain back-to-back firewalls between us and do not hand-off any direct layer 2 interfaces to each other. However, the two orgs do partner to provide each others business SSID's in each other's WiFi networks using anchor mobility. Our current solution utilizes an A/M tunnel between my org's 5508 controllers and the partner orgs 2504 controller and we explicitly permit the tunnel traffic between partner controllers for A/M to work. Last year, the partner org retired some old WiSM's and changed their wireless solution to Aruba and recently implemented Clearpass. In order to maintain A/M with us they left a 4404 operational, but due to the newer code we were running they were forced to purchase a 2504. So now they are only maintaining a limited footprint in their network with a few Cisco AP's and the rest of their coverage areas use Aruba AP's and they have indicated that they want to completely retire their Cisco WLC's. Because we host some of their SSID's on our controllers and can tunnel them to their 2504, they get all of their WiFi traffic coming from our network, however my org can only connect to our SSIDs on their campus in certain areas.
The solution I have been asked to provide is to find a way to continue providing some sort of anchor mobility services between our WLC's and their Aruba controllers. My org maintains that we do not want to simply hand them a layer 2 interface for security reasons, but they want our SSIDs to be available in all areas of the partner org's campus and vice versa. So far I have stalled the partner org's plans to retire their WLC's by telling them that retiring their WLC's will completely break WiFi between orgs, but they are adamant that some sort of A/M solution must be found.
Is there any way to do some sort of A/M between a WLC and Aruba controller and if so, is there any documentation showing configuration examples etc?
Thanks,
John

Hi John,
I do not think it will work. Even if it get working somehow, it will be operation nightmare to troubleshoot & fix a issue since both vendor will say it is NOT supported solution.
What about if you ask them to advertise your SSID (assuming it is dot1x) on their APs as another SSID on their network, but pointing it to your RADIUS & DHCP for IP connectivity (you do not have layer 2 requiremnt for this & can do this as long as you have L3 communication between each other)

Do Anchor controller and foreign controller have to run on the same code version?

Hi All,
I have a 4402 anchor controller and 8 4402/4404 foreign controllers all running on code 4.2.61.0 for 1 year without any problem. All guest users are connected to the foreign controllers and then tunneled back to the anchor controller. Right now I need to replace a 25-AP license 4402 foreign controller with a 50-AP license 4402 controller. The new controller is running on code 7.0.116.0. I am wondering if the new controller can join the mobility anchor group so that guest users won't lose connectivity after the swap.
Please advise. Thank in advance.
Robert

Wireless WISM and 4402 DMZ controller mobility issue

Hi all,
I have a really weird wireless mobility issue I need help with. I have a Wism installed in our cat 6 with version 7.0.98.0 of software. I also have a 4402 controller in the DMZ acting as an anchor controller to terminate guest traffic, also running the same version of software. The mobility anchor is setup on 4 SSID's and most of the time I don't have an issue with it.
However every week or so the data path or control path will randomly go down, so no guest traffic. Timers are configured as 10 seconds for the keep alive count and 20 seconds for the keep alive interval. I have found the following syslog information from our NMS. Not sure what these errors are and if its anything to do with this random mobility issue.
Any thoughts ??

A traceback is a device producing a trace of where it was in the software code when the problem occured.
Most often it's when a function fails/crashes. Although that is not always true.
If you have the syslog to the deepest level of debug, you will see harmless tracebacks (functions that returned no result but that might be expected). On higher level of debugs only "crashing" tracebacks are shown. In this case, the fact that you have mobility issues and tracebacks related to mobility is highly suspicious.
TAC can decrypt the traceback hex and find the exact part of code that created the problem. From there, they can link it to an existing bug (or a new one maybe ?).
Hope this clarifies !

How can I connect one 5508 and a 4402?

Hello all, I´m new to this forum. I want to consult you because of a situation that I have.
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.
Thanks so much in advance.
Regards!

The link will explain a lot, but one thing to make sure also is that your configuration between the two WLC's are similar except for host name and up address. You will also configure the ap with the primary wlc and secondary wlc info. This way the ap knows which wlc it belongs to and which wlc it needs to go to if the primary is unavailable.

Dual Radio WGB and LWAPP Controller

Hallo everyone,
I have a wireless network managed by a 4402 controller with this sw version : 5.2.178.0
The client wants to add a stand alone wgb (cisco 1242 with an ios 12.4(21) ). The standalone ap associate to an LWAPP AP using the 5Ghz interface and propagate the same ssid at 2.4Ghz (I've also tried using a different ssid ). Actually the WGB is the only AP using that SSID at 2.4Ghz. As for the wired clients of the WGB I have no problems but if the client associate to the 2.4 Ghz SSID, I see it associated on the controller but no traffic from or to the client is allowed.
If for any case, the 5Ghz interface is resetted and the association betweeen the WGB and the controller is reformed, the 2.4Ghz client starts receiving and receiving traffic.
Any idea how to set things up from the the first association?
The wgb ssid is not set as infrastructure-client and the controller correclty identify it as a WGB client. In the same way the controller correclty see the 2.Ghz client like a wired client of the WGB but unless the association b.t.w the WGB and the controller is reset, no traffic reach the client.
I think that may be a problem related to how the IAPP protocol notify the presence of a client to WGB but I don't know how to work things out.. any idea?
Thank you in advance!

The 3600 series Access Points can have either internal or external antennae. You can tell by looking at the top of the AP. If there are 4 antenna connections (one in each corner) then they are external antennae.
If you cannot get to the AP to check them physically, the antenna type is also denoted by the part number.
AIR-CAP3602I-x-K9 has internal antennae
AIR-CAP3602E-x-K9 has external antennae
The 3600 does have dual radios built in, operating in the 2.4GHz and 5GHz frequency ranges. However, for them to show up as such, you have to enable both radios on the AP. You can do this either through the WebUI or the CLI.
The 802.11ac option is an external module that is attached to the underside of the 3600 AP. Please find the datasheet for the module here:
http://www.cisco.com/en/US/prod/collateral/modules/ps12859/ps13128/data_sheet_c78-727794.html
The 1552c Series access points are also dual-radio systems and should also have both radios turned on through the WebUI or CLI. Note the quote " The Cisco Aironet 1552C/1552CU Outdoor Mesh Access Points are dual-radio systems with DOCSIS 3.0/EuroDOCSIS 3.0 (8x4 HFC) compliant cable modem for power and backhaul." taken from the datasheet for these APs found here:
http://www.cisco.com/en/US/prod/collateral/wireless/ps5679/ps11451/data_sheet_c78-641373.html
Cisco ships the APs with one Radio enabled and if you want the dual-radio functionality, you have to turn that on. Once that is done, you should see the APs show up correctly in the WLC 5508.

Clients Connect to N AP's on 5508 and get different Transfer rates than on 4404

I have have 2x 4404's (2x) and 2x 5508's all are running 7.0.240.0. When I take an 1142 and associate it to a 4404 I can connect a test client using N at 144Mbps and I can get transfer rates averaging 70Mbps (using iperf tests). When I take the same AP and associate it to a 5508, (same SSID, etc) I connect at 144Mbps but only get average 6Mbps transfer rates. I get the same results with 1252's. I get the same results if I wipe the config on the 5508 and start from scratch. It only happens when connecting at a/n, when I use a b/g AP such as 1132 I connect at 54Mbps on either controller and get transfer rates of 24Mbps. I have enabled disabled LAG (rebooted), moved the 5508 to connect to the same swtich ports, swapped GBICs. The issue happens on both 5508s, TAC has been unable to resolve this and they are confused as well.
Some of the other things I have tried:
•-          You are facing the issue on 5508's WLC only.
•-          Both the WLC and the client reports high connection speed “144Mbps”
•-          iPerf between wireless and wired showed the following:
on 4400: [124] 0.0-16.9 sec   154 MBytes 76.5 Mbits/sec
On 5500: [124] 0.0-94.3 sec 70.2 MBytes 6.25 Mbits/sec
•-          The AP is the same AP, you just bounce it from 1 WLC to another.
•-          The location of the AP is the same in all the tests, but it can be replicated with an 1142 anywhere on site and get the same results.
•-          The test PC is the same in both cases
•-          The configuration is the same on both WLC’s confirmed visaully in GUI and via CLI outputs and compaired.
•-          The switch is the same, but have tired swapping 4404 and 5508 in data center.
•-          Tried to swap the GBICs.
•-          Used different ports on the 5508 (not just diff GBICs)
•-          Disabled the LAG to rule out the load balancing algorithm.
•-       Replaced the patch cables
Used same ip space that the 4404 is using without sucess.
Upgraded my second 5508 to version 7.5 and exact same resutls.
Any ideas?

Hi
In my 5508 WLC i have exactly the same problem as you gsutherland
I tried apply this command config 802.11b 11nSupport a-mpdu tx priority all disable
and i get message

WLC 5508 and associated AP's

Hi,
I have a problem with a poor signal. I have two WLC 5508 and 10 ap's 3502. So, that I have two wlc on the network I decided to divide this 10 ap's.
WLC 5508 has 7.0.98 software version.
The 5 first ap was associated to one wlc and the other 5 to second controller.
Two problems was observed, first that some clients which try connect to AP associated to second controller have problem to obtain IP address from DHCP pool on first wlc.
The second problem is that on this two WLC was configured two DHCP pool. One controller assigns address for a dedicated WLAN and the second wlc assigns address for a second WLAN.
This two WLAN's is broadcast on two wlc.
Kamil

Hi Nicolas,
The APs are 3502I model and now are located on the lower ceiling.
From Thursday all APs are associated to only one WLC the second one is just only as a backup and from this time there are not any problems with a signal. This information is directly from clients.
The DHCP pool is located on the first WLC now.
Also, I considered to use switch or other machine as a DHCP pool but it's problematic to deploy now.

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..

Looks to be wither a duplicate address issue or a configuration issue. Try to test with only using the 2.4ghz and then again with only the 5ghz and see if you see a difference.

WLC 5508 and LAP1310 - Not syncing up!

As the title states I have a WLC 5508 and a LAP1310 that will not sync up.
The error stated in the traps log is "AP with MAC (xxxx.xxxx.xxxx.xxxx) is unknown."
WLC software release is : 7.2.103.0
IOS on the AP is : 12.4(18a)JA2
Upon some investigation I found that the "AP with MAC is unknown" error usually points to one of two things:
A. WLC firmware needs to be updated
B. AP needs to be updated.
C. The AP is not compatible with the WLC.
I am leaning toward solution C and I am looking for a conformation or a correction, if anyone could help out that would be greatly appreciated!
I've tried reading the compatibility matrix released by Cisco, but I found it mildly confusing as to what is and isn't supported by each software release.
Sources - http://www.cisco.com/en/US/products/ps6366/products_tech_note09186a00808f8599.shtml#lap1250
Problem 11: 1250 LAP Not Able to Join WLC
The setup consists of a 2106 WLC that runs version 4.1.185.0. A Cisco 1250 AP is not able to join the controller.
The log on the WLC shows this:
Mon Jun 2 21:19:37 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Mon Jun 2 21:19:37 2008 AP Associated. Base Radio MAC: f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:26 2008 AP Disassociated. Base Radio MAC:f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:20 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Mon Jun 2 21:19:20 2008 AP Associated. Base Radio MAC: f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:09 2008 AP Disassociated. Base Radio MAC:f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:03 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Solution: This is because the Cisco 1250 series LAP is not supported on version 4.1. The Cisco Aironet 1250 Series AP is supported from controller versions 4.2.61 and later. In order to fix this issue, upgrade the controller software to 4.2.61.0 or later.
Problem 16: 1000 series LAPs not able to join the Wireless LAN controller, WLC runs version 5.0
This is because WLC software release 5.0.148.0 or later is not compatible with Cisco Aironet 1000 series APs. If you have a Cisco 1000 series LAP in a network, which runs WLC versions 5.0.48.0, the 1000 series LAP does not join the controller and you see this trap message on the WLC.
"AP with MAC xx:xx:xx:xx:xx:xx is unkown"

WLC (4402) Controller Redundancy

I currently have 1 x 4402 Controller setup in the HQ. This has a failry extensive wireless environment.
If there was to be a failure then the HQ has lost all Wireless communications.
I would like to implement another controller and use this as a backup.
Anyone have any implementation thoughts surrounding this? best practice and anything I need to consider?
Thanks

1. Add a second controller that is the same size controller that you currently have. Be careful to never exceed the total capacity of a single controller, or else you lose your full redundancy.
2. Keep the controller at the same site, but connect it to a different switch in your core. If you are connecting it to a chassis switch, connect the two cables to different blades for highest redundancy.
3. Configure each controller to use LAG (Etherchannel).
4. Split your access points between the two controllers. Best practice is to group APs together that are physically close, so roaming occurs between APs that are on the same controller. Don't "checkboard" your APs when assigning primary controllers.
I hope this helps!
