Cisco Wireless :: Mobility Group Between Controller 4400 And Virtual WLC
Mar 7, 2013
I read the configuration guide about the 7.3 release. And I figured out that you will need a hash key for establishing a mobility group relation between a controller and a virtual controller. The 7.3 release for the 5500 series works fine for me.But the latest release 7.0.235.0 for the wireless lan controller series 4400 does not have a functionality to add a hash key while creating a new mobility group member.The command "config mobility group member hash" is totally missing. How to establish a mobility group between a 4400 controller and a virtual then ?

It seems the 7.3.101 version Mobility group peer cannot up,: refer to the attach,
Peer 1: version: 7.3.101
Peer 2: version 7.0.98
Peer3: version 7.2.103
Today we got new two WLC for Anchor use, and config the mobility group, but it's failed and cannot up, the ping is ok.

I recently add a second CT5508 to the network, but when I tried to add the first 5508 to the mobilty group I received a message like this:
"error in creating member"
I've tried different mobility names, via GUI, via CLI and always the same error.
I've verified twice or more than twice connectivity issues or any error on the entering the MAC and IP of the controllers, everything is fine.
I'm using version 7.0.116.0

I have to WLC's a 4402 and 5508 in a mobilty group. they are both running 7.0.116.0. They are configured to use Web Authentication. We are having complaints that Users are having to re-authenticate when moving around the office. My theory is they are moving from one WLC to the other and then requiring to re-authenticate.

We have a customer that have 2 5508 as primary and backup controller and a 4400 as an anchor controller. We plan to upgrade the 5508 to 7.3.112.0 and the 4400 is already 7.0.116.0. Will there be any issue if the anchor controller is not the same code as the foreign controller? Do I also have to upgrade the acnhor controller to 7.0.240.0?

for some reason our wlan-controllers were build up to be standalone instead of beeing one mobility-group. I would like to change this in order to use all features of HA.
let me describe our scenario: two WLCs 5508 running SW ver. 6
- same subnet
- both are running in master controller mode
- different hostnames, ip-addresses, etc
- all settings for WLANs and AP-groups (exept the APs themselves in these groups) are the same
- in total at this moment we are running around 100 LAPs configured one half on WLC#1, the other half on WLC#2
I don't know exactly why, but when that setting was installed, someone already configuredHA for each accesspoint... e.g.:
- AP#1 primary WLC#1, secondary WLC#2
- AP#2 primary WLC#2, secondary WLC#1 but without WLC#2 knowing the configuration for AP#1 it makes no sense, correct?
so my question is: how should I do the migration in the best way?
is it easy as:
- disabling master controller mode on WLC#2
- configuring both WLCs into one mobility group
--> WLCs are negotiating their configurations for the APs

I have a 4400 and a 5508 WLC in the same location We want to be able to roam between ap joined to both the 4400 and the 5508 using only one ssid
Do I only need to create a mobility group and add both WLC then create only one WLAN on one of the controllers and it will be shared across bot WLC.

I have a customer buys 12 x WISM and build up a mobility, when I add the final WLC to mobility, it prompts that there mobility group has reached the max of mobility member, but the total member is 23, according the configuration guide, it should be allow to 24 member, do I hit some bug? My using version is 7.0.98.0.

We have 4 x 4xxx WLCs setup in our Core. I just created an AP group in one of WLC and in theory I should see that AP group in the other 3 x WLCs
For some reason, I do not see that AP group appear in other 3 x WLCs. Very much appreciated if someone could point me to the right information or trouble shooting steps.

I have a Question i am testing mobility group with Failover for redundend connection between 2 Cisco 5500 Wlc.On both the controllers i got the mobility working And both the controllers have the same version.And configuration. But when i unplug the main controller the access-Points don't convers to the second one .The just keep on creaming can't find the main controllerAlso with this thus the second wlc need to have the same.Interface ip address like management.

I am setting up officeexten. I have placed the officeextend wlc in the dmz with an mgmt ip of 192.168.10.2. in the process of anchoring this to the internal wlc. Also the ip on the firewall for this interface is 192.168.10.1
1. does the mobility group need to match the same on the internal wlc ?
2. Now do i need a NAT transnational on the firewall for the external WAN ip (AP primed address say 66.10.10.10) to NAT back to 192.168.10.2 ?
3. The 5508 WLC is running on ver6.0.199.4 (license level base) - will this support office extend?

I have 2 5508 controllers in a mobility group. Any good way to keep the configuration between the 2 controllers synched up?
I thought about copying the config from my primary controller to the secondary controller, but I would think there is a more elegant way to make this happen.

I have a Cisco Series 4400 WLAN controller and I'm trying to connect a lightweight AP to the controller. I have already assigned the switch port to use my wi-fi VLAN, and have connected the AP to the switch. After a few minutes, the light on the AP goes from green to light blue (indicating it's serving clients). When I log into he wi-fi controller to look for the Ethernet mac address of the new AP, I do not see its Mac Address. I want to be able to rename the AP to reflect where it will be used, but need to select the AP via its Ethernet mac address before I can make any edits like changing its name etc. I've gone through the "monitoring" menu, selected "All" and still do not see it in their via its MAC address. I also will select the "wireless menu" which lists all the AP's on my network, listing in order from on the longest running, to just powered on.Is there something I'm missing like a "re-scan" that scan's all devices?

I'm looking for a document that states the best practices for WLC configurations (Management/Security/AP's..etc). I can currently only find the following document:URL
But this document has last been updated in 2008, in a few days that's almost 5 years ago, and we all know how quickly technology is evolving. 10Gb wireless is around the corner, with 1GB starting to go production now. This document also mentions the 4400 (which is end of life).

I've download a login.html into the controller successfully, but when I preview the page there isn't an accept button. Do I need to create the accept button with the html file or is there some place I need to enable on the controller itself. After download the .tar file I reboot the controller but no luck. I also create a java script button redirect but it didn't redirect to where I needed to go. It just stuck on the splash page.

give me the run down on the features removed from the 4400 series in the 2500 series? Obviously 4400 is now EOL, and so i cannot purchase new. Therefore I was looking at the 2500 for my implementation to save costs also.I would like to have two SSID's, running seperate VLAN's, one voice, one guest, trunk the link to the AP's, which will be 1131AG or newer, N possibly. Voice needs to be encrypted with WPA or WPA2, guest needs to be open using the guest access feature. Here's a sample but with EAP:
[URL]
Is this supported to have WPA on one SSID and Guest access on the other? i did spot a paragraph in the 4400 manual stating that certain restrictions apply regarding one SSID having encryption and the other being guest mode?I notice also in the WCS documentation, it doesn't explicitly state it supports the 2500 series under the managed devices section?

I want to configure a Cisco Wireless Lan Controller (4400 and 5500 series) with to data ports for failover? I think the primary and secondary ethernet connections should be configured as trunks. I cannot find anything on CCO about this or on the internet per se. I know how to configure for failover with APs but cannot find anything on how to configure the controller in case an the ethernet port goes down.

We are facing an issue with a customer where a Cisco 4400 Series controller is blocking the 802.11a/n Radio Interface of a 1250 AP. The radio shows as down on the controller GUI. The error message on the GUI is that the 'Regulatory Domain' is not supported. This can be seen from the attached screenshot. Also relevant parts of the WLC configs are attached. WLC: Cisco 4402 WirelessWLC Country: SADevice: Cisco Lightweight Access Point 1250 (LAP) is controlled through the 4402 Cisco Wireless LAN Controller (WLC)The operating system version of the LAP: c1250-k9w8-mx.124-18a.JA version of the WLC: Software Version 5.2.178.0 The problem is that the controller shows that the 802.11a/n Radio Interface in Radio Slot # 1 is always down , the customer tried to manually 'no shut' the AP interface from the console and it worked , but obviously this solution would not work as the configuration cannot be saved (LW AP).

We have a Cisco 4400 series wireless controller deployed as a Guest Anchor in a private DMZ. We have 13 foreign controllers anchored to this for Guest Wireless. We recently anchored 17 additional controllers to this Anchor controller. Since we have done that, periodically on just 3 of the foreign controllers, the control path shows down on the mobility peer, then comes back up. We have had this issue in the past, but it resolved itself. However, now we are seeing this issue again. Are we reaching a limit on EoIP tunnels? I have read that there is a max of 71, and that is per controller, not SSID. We do have a firewall in the middle but all necessary ports are open.
We have had this issue for quite sometime, it just does not happen frequently. Since we have added the additional controllers, it is now happpening very often, but only with 3 controllers. There is not much in common with these 3 controllers. 2 are 4400 series, and 1 is a 5508. All 3 are local on a campus LAN, different networks. Could it have anything to do with memory or utilization?

I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect. But I am not having any luck getting into a controller. Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc. This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers. Niether of which are set to "Master" either.

We have two 4400 WLC's. We have around 20 access points in our network.If we assign controller1 as primary for half of the access points and controller 2 as primary for the other half, does this mean the association of the ap's indicate load balancing by the controllers. Does this mean wlc does load balancing as different ap's associate on different controllers. or does it only server as active-standby wlc.

We are planning a WLAN upgrade and the security policy is to forward wireless Guest user traffic to the DMZ controllers. We are now considering the Virtual WLAN Controller and all AP's will register with the virtual controllers and we will use Flexconnect for Staff and internal traffic that will switch their traffic onto the local switch.
We wish to forward the guest traffic to the DMZ Guest Anchor controller which will be a 5508 controller. This will also offer Office Extend AP service.I have looked at teh virtual controller docs and not very clear if this deployment model is supported. Below is a diagram of what we wish to deploy and is this a supported deployment model.

I know how to access the GUI from the service port. However, I am not able to access from Port 0. IPs have all been properly set. We have a management VLAN in our enterprise. I have configured the WLC management interface for an ip on that subnet. Port 0 is connected to a 3560G switch. I have set the switch port to be an access port to the management vlan and I have tried to set the switch port as a trunk, with the native vlan set to the management vlan. I am not able to ping nor access the web GUI remotely via the management vlan.

When using the USB printer port share function, I found that some PCs, which had never physically connect to a USB printer before, will not have the virtual USB printer port in the port selection. In this way, TP-Link's USB printer controller will not be able to setup the connection. The PC will not be able to use the shared printer from my WDR3600.how can I create a virtual USB printer port in the remote PCs (without need to physically connect a printer to them) or other method to use the shared printer?
