Cisco 526 controller and AP541N

Hello,
I have a cisco 526 controller. Since this device is EOL. Can I still use 526 controller with AP541N? What are the limitations and problem configuring with
AP541N?
Thanks.
Dipendra

Hi Dipendra,
The 541N is NOT supported via the 526 Controller
With the Cisco AP 541N, you can:
• Easily set up, configure, and manage multiple wireless access points, without the need to invest in a wireless controller

Cisco 526 WLC and 2106 WLC in one Mobility Group

Hi,
is it possbile to build a solution with one Cisco 526 Wireless Express Mobility Controller and one Cisco 2106 Wireless LAN Controller in one Mobility Group regarding seamless roaming??
Thank for your answers
Best regards
Stephan

I don't know if it is possible, but I would think if you had any issues, TAC wouldn't support it. Try opening a case with TAC to see.

Support for Appletalk on the 526 controller (and others to)

I have noticed that from version 4.2x the controller does not seem to pass appletalk traffic through to the wireless clients.
I started to look around for some information but there are quite few resources for the 526. So i started to read the release notes and read the release notes for the 2100 controller and noticed that it doesn't support appletalk at all.
My question is simple, is it common for cisco's wireless products to not support appletalk? Is this maybe an step on the roadmap to get rid of appletalk completely =)

Appletalk bridging is supported in 4400, WiSM, or 3750G. If you insist to use 526, you need to configure HREAP on the AP and HREAP local switching for the WLAN.

Cisco wireless controller and AP-binding domain how do you integrate wireless domain authentication?

With Cisco equipment wlc 2500 and AP 1600 combines windows 2008 r2 domain controller to achieve the following purposes,
1, all cell phones and laptops can access the wireless network with a domain user authentication.
2, the guest network should how to do it?
My idea is:
Made a total of two ssid below
Mobile users cnnewcity_mobile: Use webportal certification, so the center certification, local forwarding
Computer users cnnewcity_wifi: transparent certification, local forwarding, local authentication
The basic steps are as follows:
1, set the Radius server clients (AP or controller)
2, locking authorization group --- this should be based on the domain user group authorization radius server
3, the mobile roaming - different locations on the DHCP server choose to do this you have to consider the next 43
4, the establishment of a two vlan to a mobile user to the computer user, create a DCHP scope on the DHCP
I do not know if you have wood there are better ways?

Integrating the AD to the WLC Requires:
1. AD to be registered:
AT: Security->AAA
   AT: LDAP
   CLICK: New
    Server IP:    <AD IP>
   Port Number:   389
   Simple Bind:   Authenticated

Cisco 4402 Controller and 1113 ACS Set up??

Hello all,
I have a 4402 and 1113 I am trying to set up. I have tried everything to try and get the controller to talk to the 1113 with zero luck. Is there a step by step example configuration out there?

There are many reason why an AP is not able to join AP.One Main reason could be AP unable to deted the controller's IP address on the Domain.Refer URL

2 controllers - Cisco 526 wireless mobility Controller

Hi,
My setup consist of 2 controllers(Cisco 526) and 8APs.
Cisco documentation has stated that it supports for 2 controllers per network. But has not shown how to configure it.
Please advise on how i can configure the 2nd controller to aid 8APs.
How would the APs be managed by 2 controllers? Do i see both controllers as 1 virtual controller on the GUI/CCA, or do i have to manage 2 separate Cisco 526 controller.
Please advise

You'll need to manage two separate controllers, unfortunately. You simply need to give them identical configurations (with different IP addresses), and they'll work together to service the access points. The APs will associate to whichever controller has more available slots, and the APs should find the other controller in case theirs goes down.
I'm not too familiar with 526 configs, but you should be able to configure the APs to use a specific primary and secondary controller. Look under the AP configuration once the APs have associated to a controller.

Cisco 526 Wireless Express Mobility Controller

We have just purchased at UC520, 526 Controller and a LAP521 controller. We got the UC520 up and running in 15 mins, but the 526 does not include very much documentation. We can not get it to find the 521 AP on the network nor will it go to layer 2 mode. I don't want to setup layer 3 routing for a 4 PC office. During the setup the only option it gives is layer 3 and the documentation says it will do layer 2? Can anyone give me any assistance?

The controller reference between layer2 and layer3 is a little misleading. Having the WLC (WLAN Controller) in layer2 mode means that it uses layer 2 frame headers to place the LWAPP information in. With the WLC in layer3 mode, the WLC places the LWAPP header in the IP packet header instead of on the layer 2 frame header. The newer AP's support only understanding the layer3 mode of placing LWAPP info in the layer3 packet header. In either mode, you can still configure your network with only one VLAN/subnet, which sounds like your goal. To summarize, the WLC's mode of layer2 vs layer3 only references where the LWAPP header is placed in either the frame or the packet and in no way correspondes to how you design the vlan's/subnet's of your network.

Load balancing with 526 controller

Good Day,
I would appreciate confirmation of this configuration or, if it is wrong, suggestions.
I have been asked to provide wireless access for a conference of about 150 in an auditorium about 50m x 20m. The attendees will be using their access just to browse, check e-mail etc. We have a radius authentication system in place that is available.
From what I have gathered, it appears that if I get a 526 controller and 4 521 access points I can advertise one SSID and configure the access points/controller for load balancing to maintain decent speed fot the users.
Is this correct?
Also, is there a benefit to getting better equipment. Price is not really a factor but this setup will be used only a couple of times a year and I don't want to throw money away. But it has to work, and I'm on a short deadline...procurement, configuration and testing by 6/4/07.
Thanks

The Cisco 526 Wireless Express Mobility Controller can be used with up to six access points per controller. So 5 -6 access point would be a better option . Refer URL

LWAPP cannot translate cisco-lwapp-controller

Hi all:
I had add a hostname to DNS server as CISCO-LWAPP-CONTROLLER . and i use my controller as a internal DHCP server , it will assign ip to a lot of vlan. My lightweigh ap cannot translate the cisco-lwapp-controller and other a record at DNS server .

Can you translate that on the local lan? Verify that the manamgement and ap-manager is configured for vlan "0" untagged and that the trunk port is setup with the native vlan of the WLC management and ap-manager interface. If you console in the ap and power cycle the ap, what does the log show. Post the log so we can take a look at it.

Can AIR-AP521G-x-K9 be controlled by the Cisco 526 Mobility controller ?

I am going to buy a AIR-AP521G-x-K9 with IOS software which is a stand alone access point.
However, later on I may buy a Cisco 526 Wireless Express Mobility controller in order to expand my wireless network.
As I know at that moment I need to buy light weight AIR-LAP521G-x-K9 instead of AIR-AP521G-x-K9
However I want to know if the stand alone AIR-AP521G-x-K9 can be control by the mobility controller without doing any change to the AIR-AP521G-x-K9 ?
Thanks

Hi Pak,
The AIR-AP521G can be converted to Controller based mode via software upgrade so your investment is protected should you decide down the road to switch to Controller based. Have a look***;
Q. Which access point products are included in the Cisco Mobility Express Solution?
A. Two Cisco 500 Series Wireless Express Access Point products are in the Cisco Mobility Express Solution; their part numbers follow:
AIR-AP521G-x-K9 (standalone access point)
AIR-LAP521G-x-K9 (controller-based access point)
The hardware for these products is the same. The products have different software,*** but the access points can be converted from standalone mode to the controller-based mode with a simple software upgrade.
Up to three access points can be managed by Cisco Configuration Assistant. More than three access points in the network requires the controller as well.
From this good Q & A doc;

Hope this helps!

Cisco Aironet 3502i and Virtual Wireless Controller- Question

Hello everyone,
As soon, I purchased two Cisco 3502i and Cisco 1142 however, two issue are that I don't have controller and smartnet. As my purpose, it using for Home Use but house with 2,500 Sq ft with two floor and new 24x24ft garage with two floor. I put two Cisco 3502i for garage and one cisco 1142 in house on second floor. Separated for multi media, gaming, streaming high resolution video, parts, and downloads programmings online. It will run with Cisco Catalyst Express 500 with 24 ports (4 POE) and two gigabit ports. In house, it have Dell Poweredge 2850, Cisco Catalyst Express 500 with 24 ports POE and 2 ports gigabit.
I thought to make my own developing with my first time using Wireless Controller. I wanted to try out with Virtual WLC on Dell Poweredge 2850 running ESXi 4.1.
Specs for Dell Poweredge 2850:
- 2x Intel Xeon Dual Core 3.8 GHz
- 4GB RAM (Will upgrade to 12GB soon)
- 2x 146GB and 2x 36GB SCSI
- 2x 1 Gbps built in and 4x 1 Gbps PCI-X
Developing with Untangle and pfSense to make it support with LADP and VLAN to both Cisco Express 500 using 4 gbps PCI-X. I have read the requipment list to use Virtual WLC but it seem met the requipment for my 2850. If someone offer me to get Virtual WLC and IOS from their, I accept to "borrow" it. I do go college which is Rochester Institute of Technology at New York and my major is Applied Computer Technology. I live here at Hampton Road, Virginia. Just in case if you might know about RIT. I just start to learning myself with Cisco books.
I have a question:
- Is there possible to get trial or full version of Virtual WLC?
- Is there possible to get Lightweight or Autonomous IOS for Cisco 1142 and 3502i?
- Does it supported Dell PowerEdge 2850?
- Does 3502i support Autonomous? (Not actually but I have researched around online about that it will work with 1262's IOS)
Thanks
Gage

Answers in-line...
I have a question:
- Is there possible to get trial or full version of Virtual WLC?
No. You will need a SmartNet contract (or a freshly purchased device) to obtain software from cisco. Nobody will provide this to you.
- Is there possible to get Lightweight or Autonomous IOS for Cisco 1142 and 3502i?
No. You will need a SmartNet contract (or a freshly purchased device) to obtain software from cisco.
Nobody will provide this to you.
- Does it supported Dell PowerEdge 2850?
Cisco doesn't go in to great detail regarding the actual Hardware requirements of the vWLC (as far as ESX Host requirements). Primarily, making sure you are running ESX 4.x/5.x is necessary. The vWLC provisions 2Gb of RAM and 8GB of thick provisioned storage, so if your host can accomodate I don't see any reason it wouldn't work.
- Does 3502i support Autonomous? (Not actually but I have researched around online about that it will work with 1262's IOS)
Yes, with the latest versions of IOS 15.2(2)JB, full functionality in autonomous can be achieved on the 1550, 3500, and 3600 series APs

Problems between a Wireless Controller and a Switch.

I have a Wireless Controller 4402 connected to one sw2960G.
I configured the controller with LAG and the switch (sw2960G) with etherchanel.
I connected the controller 2 distribution ports to the 2 ports of the switch (configured with etherchanel).
It worked like it should work.
But the problem is like this: if I take one cable that is connected to the switch and unplugged that cable from the switch (if that cable is the one connected to controllers port one) I have connectivity between both machines.
If I plug in the switch the cable connected to controller port one and take the other cable and unplugged that cable from the switch I stop the connectivity between the two machines.
I think that was not supposed to happenâ¦ because the LAG in the controller should put every AP in the second controller's port, and the connectivity between the machines should not end.
Can any one help me?
Can any one tell me what I am doing wrong?
Thanks in advance,
Rui

With LAG enabled in the controller I think I can have only one ap-manager interface.
The LAG will (it is supposed to) do the load balance automatically.
I mean, if one of the interfaces is âdownâ the other will have to coupe with all the AP's.
I should have always connection between the controller and the switch.
The STP of the controller is configured by default (STP Mode = OFF).
In the case of etherchannel load balanceâ¦ I saw the Cisco documentation and I did not saw any thing about that. I think that The LAG as to do that for the controllerâ¦ I'm right about that?
I will see the link that you advisedâ¦
Can you help me?
Thanks,
Rui

You configuration is not correct. You can remove the line ‘domain-name CISCO-LWAPP-CONTROLLER.mydomain.com’ or replace it with ‘domain-name mydomain.com’ and configure the DNS server with both "CISCO-LWAPP-CONTROLLER.mydomain.com" and "CISCO-CAPWAP-CONTROLLER.mydomain.com" pointing to 172.16.00.25.
I suggest that you remove this line and forget about DNS and go for DHCP option 60 and 43 as you already have configured. You do not need both the DNS configuration and DHCP option 43.
Since you have configured ‘option 60 ascii "Cisco AP c1250"’ and ‘option 43 hex f104ac100019’ then your 1250s should try to associate with the controller 172.16.00.25.
Please post more of the syslog and look for events regarding DHCP option 43.
Is the address 172.16.00.25 for the WLC correct?

André

802.1x Authentication using Cisco Phone LSC and IAS 2003

I'm trying to authenticate Cisco 7975 phones using the LSC and Microsoft IAS 2003.
The CA was generated from the IAS server (Domain Controller) and was imported and used to generate the LSC that have now been deployed to the phones.
Does anyone know how to configure the IAS server to authenticate the phones?

HI Saad,
Check this link to get info about EAP Types:
http://www.networkworld.com/article/2223672/access-control/which-eap-types-do-you-need-for-which-identity-projects.html
I will prefer to use EAP-TLS because of the security.in This type you need certificate on both side(Client and Server), also you can add AD to authenticate user.

Cisco WLC 5508 and LACP

Hi Fellows,
I wanna know if 5508 Cisco WLC support LACP or not. Actually i work in a project where i must
connect WLC 5508 in Enterasys Switches with Link Aggregation.
Enterasys Switches support LACP 802.3ad but when i learn Cisco Books i see that WLC 5508
doesn't support LACP.
Can you help please ?
Sincerely
Joseph

Hi,
Please take a look into the config guide:
http://www.cisco.com/en/US/docs/wireless/controller/7.0/configuration/guide/c70mint.html#wp1277652.
You can read there:
Once the EtherChannel is configured as on at both ends of the link, it does not matter if the Catalyst switch is configured for either Link Aggregation Control Protocol (LACP) or Cisco proprietary Port Aggregation Protocol (PAgP) because no channel negotiation is done between the controller and the switch. Additionally, LACP and PAgP are not supported on the controller.
HTH,
Tiago
