Virtual Wireless LAN Controllers

Hi Guys,
Are all APs supported by Physical WLC also supported by the Virtual WLC? or they support a selective few?
Thanks in Advance

Hi Chandimal,
Adding to Leo, vWLC only support FlexConnect mode AP.
Here is the WLC compatibility matrix where you can find which AP model support under which version of WLC code.

Voice over IP Roaming problems between 2 Wireless Lan Controllers.

Hello,
we have problems with Voice over IP roaming between 2 Wireless Lan Controllers, this problem is not always happening. I have attached the detailed configuration. We are using LWAPP 1242 & WLC 2106 Controllers.
The phones they are using are Siemens Enterprise optiPoint WL2.
Is there maybe something wrong with the configuration our can I try some different settings?
Regards,
Jordy Broekhuizen

When a wireless client associates and authenticates to a WLC, it places an entry for that client in its client database. This entry includes the MAC and IP addresses of the client, security context and associations, quality of service (QoS) contexts, the WLAN, and the associated LAP. When a client roams to another LAP associated to the same WLC, it just updates the client database with the new LAP information so that the data can be forwarded appropriately to the client. When a client roams to a LAP associated with a different WLC, either in same or different subnets, it sends the information in the client database to the new WLC. This helps client to retain its IP address across roams and maintain uninterrupted TCP sessions. For more information on roaming in the WLC environment.

Memory on Wireless Lan Controllers

Does anyone know anything about the wireless lan controllers regarding flash memory?
I have found a command:
show memory statistics
It gives you the total DRAM in the device.
I'm looking for the size of the FLASH memory device in the WLC controller.

Nevermind....
show sysinfo gives me the output desired.

Wireless LAN Controllers

Hello --
Do I need Cisco switches to use the controllers? Also, with multiple sites, do I need one controller at each site, then can I use WCS to manage them from a central location?
Thanks,
Ohamien

Ohamien,
You do not "need" to use Cisco switches to connect to the controllers, but it is always recommended =). As for remote sites, it would depend on how many AP's you would need per site. If you need less than 5 you could do HREAP with local switching, but if you needed more than that you would need to get a controller for that site, and then you could use WCS to manage all the controllers.

How to change RTS Threshold in Wireless LAN Controllers

I've read some opinions that lowering the RTS threshold can help 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. Does anyone know if this is possible and how to do it. Thanks in advance.

According to Cisco this feature does not exist in controller-based environments. This is what I get when I try to configure the RTS setting from the CLI:
(Cisco Controller) config>slot 1 rts threshold 1024
enable rts/cts only available for Mesh APs.
I have submitted a feature request so we'll see what happens. Thanks for reading and please let me know if you have any pertinent information.

Need to synch NTP on 2100 and 4400 Wireless LAN Controllers

I have 5 WLC's (3-2100, 2-4400) and need to synch the NTP server ip addresses on them. I know how to do this but have a question. Using the gui, once I apply the change to the NTP ip address and save the changes, will the WLCs need to be rebooted for them to complete synchronization?

No, you don't have to reboot the controllers. They should sync right up.

Virtual Wireless LAN Controller and 1602E: No SSID

Hello, I am trying to troubleshoot a customer's issue remotely.
They have vWLC 7.4, and a 1602E AP, running the 7.4 LWAPP image, successfully joined.
Whatever is tried, the SSID configuration is not pushed to the AP. Other configuration changes get reflected to the AP such as enabling/disabling ssh.
The goal is for multiple SSIDs connected to various VLANs to be setup, but I have simplified things for now.
So there is an AP group containing this one AP, and a single WPA2-PSK WLAN. The WLAN is bound to the management interface.
The SSID configuration does not get pushed out to the AP.
Any ideas what I should do to troubleshoot this? I can't see any obvious issues in the error logs.
Thanks...

Keep in ming that the vWLC only supports FlexConnect mode AP's not local mode. Is the mode of the AP in local or FlexConnect?
Thanks,
Scott

Virtual Wireless Lan Controller moved, licence now missing.

Our Cisco WLC version 7.4.100.0 was been moved to new ESXi servers (New hardware) as a result of this I guess the UUID has changed and voided the installed licence.
I've tried to reinstall the original licences but this fail's because of a UDI mismatch.
If I try to do a rehost the first step fail's with
Local file /tmp/license.upd not found!
Can anyone point me in the right direction to recover and reinstall our licences.

Thanks for your replies, the issue is that the guy who set this up also setup his own login Cisco account (rather than use our ScSITServices shared account) where the WLAN licences are located. He has since left and I'm trying without success at the moment to get Cisco support to change the password to allow me access to retrieve the licence.

2100 Wireless LAN Controllers

Hi,
In the WLC 2112, I can connect Access Points in the available port.
For example:
WLC Port 1 --> Connected to Switch (802.1Q)
WLC Port 5 --> AP vlan 50 (access mode)
WLC Port 6 --> AP vlan 50 (access mode)
WLC Port 7 --> AP vlan 50 (access mode)
Thanks

Cisco Wireless Control System need wireless Lan Controller ?

Cisco Wireless Control System need wireless Lan Controller , for Rogue detection

Hi Joao,
The WCS is used in conjuntion with the WLC (Wireless Lan Controller) for Rogue Detection. It is not a must for this function but more of an add-on :)
The Cisco WCS is an optional network component that works in conjunction with Cisco Aironet Lightweight Access Points, Cisco wireless LAN controllers and the Cisco Wireless Location Appliance.
From this doc;
http://www.cisco.com/en/US/products/ps6305/index.html
Overview of WCS
The Cisco Wireless Control System (WCS) is a Cisco Unified Wireless Network Solution management tool that adds to the capabilities of the web user interface and command line interface (CLI), moving from individual controllers to a network of controllers. WCS includes the same configuration, performance monitoring, security, fault management, and accounting options used at the controller level and adds a graphical view of multiple controllers and managed access points.
WCS runs on Windows 2003 and Red Hat Enterprise Linux ES 4.0 and AS 4.0 servers. On both Windows and Linux, WCS can run as a normal application or as a service, which runs continuously and resumes running after a reboot.
The WCS user interface enables operators to control all permitted Cisco Unified Wireless Network Solution configuration, monitoring, and control functions through Internet Explorer 6.0 or later. Operator permissions are defined by the administrator using the WCS user interface Administration menu, which enables the administrator to manage user accounts and schedule periodic maintenance tasks.
WCS simplifies controller configuration and monitoring while reducing data entry errors with the Cisco Unified Wireless Network Controller autodiscovery algorithm. WCS uses the industry-standard SNMP protocol to communicate with the controllers.

Inline Posture between Cisco ISE and Wireless LAN Controller

Hi,
I was looking into Cisco ISE solution for deploying NAC.
I have a question about the network topology.
In the user guide documents of cisco ISE, it is written that for Wireless LAN Controllers (WLC) and VPN devices, an additional server, Inline Posture, is needed.
However, in the following integration document, there is not an inline posture between WLC and Cisco ISE server.
https://supportforums.cisco.com/docs/DOC-18121
I want to know if Inline Posture is a requirement, if not a requirement, what are the benefits of having it between Cisco ISE Server and WLC.
Thanks & Regards

Best Practice for DHCP when Anchoring to a Guest Wireless LAN Controller

Hi all,
I'm interested in the communities opinion in relation to DHCP provisioning when using auto-anchor/guest tunneling.
As far as I can tell, one cannot use the internal DHCP on the anchor controller when using auto-anchor due to incompatibility between the auto-anchor feature and DHCP Option 82.
The scenario is as follows:
Guest controller is the anchor which provides Internet access to guests.
There is a foreign controller which is configured to anchor to the guest controller.
The internal DHCP server is configured on the guest anchor controller, therefore DHCP proxy must be enabled for DHCP to work.
DHCP proxy enables Option 82.
The guidlines for guest tunneling state that DHCP Option 82 isn't supported. (Ref: Deploying and Troubleshooting Cisco Wireless LAN Controllers - Ch14)
So, the internal DHCP server requires DHCP proxy to be enabled; this in turn enables Option 82, which stops DHCP leases being made to clients connected to the foreign controller.
Given that a guest WLC would normally be placed in a DMZ, the internal DHCP server may often be the only DHCP solution available.
I look forward to hearing your opinions.
Thanks
Rhodri Jenkins

There are a couple of options here if you need to get proxy disabled
1) pinhole with an ACL that allows dhcp to pass your internal servers
2) run dhcp on a switch, router, or firewall in the dmz
3) if you are using a cab,e modem or dsl for the guest users, you can let that do the dhcp
In general I've seen most of these in play, but I like option 2 myself
