we have opened udp/5246-5247 and udp/12222 and udp/12223 ports bi-directional but still APs are not joiningHi yes I was able to fix it up. AP first go through a hunt process to find a WLC. Can you help me to configure my Aironet 2600 series, it’s won’t discover on my WLC, thanks and I appriceate for you help I am trying to migrate APs (2702i) from WLC 2500 on 8.0.100 to a new WLC 8510 on 8.0.110. Also do you have mobility peering with 5520 & 5508 ? I would suspect that the CAPWAP tunnel to the old WLC stays up and functional until the new CAPWAP tunnel is built and ready to pass traffic to the 5520 WLC. Since these are lightweight image we cannot configure like normal IOS AP. As a founder of and an instructor at labminutes.com, Metha enjoys learning and challenges himself with new Cisco technologies. Once the LWAPP/CAPWAP access point has discovered and selected a controller, the next step in the process is for the AP to join the selected controller. I was able to upgrade the controller from 7.6 to 8.0.121 without any issues. The AP is keeping trying to resolving CICSO-LWAPP-CONTROLLER. Each method will be demonstrated with their order of priority explained. So here are the command to do this.Since I have not configured the switch port for vlan 113, still AP cannot reach its gateway. This time you can see AP successfully able to complete Discovery & Join process as it can reach WLC. If so, what are the CLI commands? 6. This include Client Hello, HelloVerifyRequest/ ClientHello(with Cookie), ServerHello/Certificate, ClientKeyExchange/ ChangeCipherSpec, ServerChangeCipherSpec (See below)Subsequent traffic is DTLS encrypted & cannot be decode  to see what’s inside. I have 2 have them and had the same issue. These are the steps AP will go through in order to register with a WLC.First challenge is to find where to send CAPWAP discovery messages ? Find answers to How I force a Cisco AIR-AP1852I-B-K9 to Join WLC? You will get faster response to troubleshoot your issue.Need to add their the mac to the MAC filter. Different IE value  indicates the type of discovery method used. Both of which had old software versions going back 2013. It looks like my APs are stuck somewhere in between the migration process. Refer belowIm looking to write a procedure on adding a new AP to a WLC.I am using controller 2500. For CAPWAP, you need to explicitly add it.What is the main difference between the L3 broadcast and Direct L3 Broadcast.Broadcast normally stays within L2 domain. You can't force a client with the Ubiquiti controller to stick to a specific AP unless there is something unique about that AP such as a different SSID. 0 Items | Total: US$0.00 Hi Rene, I have an issue with an AP not joining the WLC, I have 3 AP’s on the WLC, one of them keeps drop the connection, when I check it by show cdp nei deta it has the correct IP address and it’s up on the switch, I can bring it back up by bouncing the port but it will come up for less than 3 minutes or so, please check the debug below on the WLC. The APs are remote so i can not console into them for now. You can do this as follows via AP CLI.Once rebooted it will complain about no IP. On the CLI, sho cdp nei detail will show the IP address of any directly attached Cisco device. All rights reserved. AP issues a DHCP discover request to get an IP address, unless it has previously configured static IP.To see AP registration process in detail will remove CAPWAP AP configurations in order to remove the previously known IP. I find it interesting the minimal downtime the AP (and associated clients) see when I change the Primary Controller (in HA tab of AP) as this is how I’m moving them from the old WLC to the new WLC. The Wireless LAN Controller we were using was a Cisco WLC 2106 and could support 6 simultaneous radios. As you can see WLC is providing all the information to AP (including WLC IP – AP mgr, Name, etc)Then AP send the Join Request & expecting Join Response from WLC. (see below)If you took a wireshark packet capture of the WLC connected switch port you can see the details of each of these types of packet. The environment is running a dhcp where I neither I can configure option 43 nor host entry for CICSO-LWAPP-CONTROLLER in the DHCP server. lwapp ap controller ip address capwap ap controller ip address In the image below you can see the AP joining the WLC instantly after setting the IP Address manually. It discovered, joined and downloaded the updated software from the controller without incident. We attached the first access point and it connected just fine. Part 1 of this video covers the basic of controller discovery with L3 and directed L3 broadcastMetha Cheiwanichakorn, CCIE#23585 (RS, Sec, SP), is a Cisco networking enthusiast with years of experience in the industry. We had confirmed the Wireless LAN Controller was on the latest software release. Previously known WLC IP, AP will rememberup to 24 previosly learnt WLC IP address & send discovery to them. 1) Why it resolving DNS domain name after got the IP address from the DHCP ?1-2) AP goes through all discovery method and build a list of candidate WLC. I can see the discovery request and respose from these APs to the new controller.

I am stuck with Cisco 3605 AP for a registration with the Cisco virtual WLC. Statically Configured from AP CLI I’d love to hear your experience and/or input on the subject. Copyright © Lab Minutes 2012-2016. Thank you.Great, make sure you configure WLC name & IP address in AP High Availability ( primary, secondary, )tab once registered the AP to WLCIs it possible to assign Static IP address to Cisco 1832/1852 AP? Also Message Element value 1 which indicate Static Configuration. DNS- AP try to resolve CISCO-CAPWAP-CONTROLLER.local-domain or CISCO-LWAPP-CONTROLLER.local-domain to find an IP of a WLC 5. The AP console is not allowing me to enter anything in the console, it is keep renewing the IP address from the DHCP to get the controller IP address in the either by option 43 or by resolving the name.Try to put AP on to the same as WLC management interface vlan & seeEnter the above command & then you should be able to issue those CLI commands.FYI on capwap control packet encryption, test capwap encr was removed from 8.0 code per CSCut91240.It seems Cisco does not want this command to be available any furtherI´m Luciano from Brazil, and I have a Serie 1600 and my AP give this message after update Firmware to version Most actual.Translating “CISCO-CAPWAP-CONTROLLER.revicom.local”…domain server (192.168.11.1)What can I do to solve this, can you help me please.Do you have a WLC ?
