What’s New in This Release
This section provides a brief description of what is new in this release. For more information about these features, see the Cisco Wireless LAN Controller Configuration Guide.
- The Cisco Wireless Controller on Service Ready Engine (WLCM2 on SRE) platform running on ISM 300, SM 700, SM 710, SM 900, and SM 910 is supported in this release. For more information, see http://www.cisco.com/c/en/us/products/wireless/wireless-controller-software-sre/index.html
- The Cisco Aironet 2600 Series Access Points are supported. For more information, see http://www.cisco.com/c/en/us/products/wireless/aironet-2600-series/index.html
- Until the previous release, the Cisco Aironet 1520 and 1550 Series outdoor access points could work only in Bridge mode as RAP or mesh access points as MAP. With this release, these APs support the following two non-Bridge modes for both 2.4 GHz and 5 GHz:
Note Enhanced local mode (ELM) is not supported when the device is in Local mode.
- 802.11r, which is the IEEE standard for fast roaming, introduces a new concept of roaming where the initial handshake with the new AP is done even before the client roams to the target AP, which is called Fast Transition (FT). The initial handshake allows the client and APs to do the Pairwise Transient Key (PTK) calculation in advance. These PTK keys are applied to the client and AP after the client does the reassociation request or response exchange with new target AP.
802.11r provides two methods of roaming:
– Over-the-DS (Distributed System)
The FT key hierarchy is designed to allow clients to make fast BSS transitions between APs without the need to reauthenticate at every AP. WLAN configuration contains a new Authenticated Key Management (AKM) type called FT (Fast Transition).
Note Legacy clients cannot associate with a WLAN that has 802.11r enabled if the driver of the supplicant that is responsible for parsing the Robust Security Network Information Exchange (RSN IE) is old and not aware of the additional AKM suites in the IE. Due to this limitation, clients cannot send association requests to WLANs. These clients, however, can still associate with non-802.11r WLANs. Clients that are 802.11r capable can associate as 802.11i clients on WLANs that have both 802.11i and 802.11r Authentication Key Management Suites enabled.
The workaround is to enable or upgrade the driver of the legacy clients to work with the new 802.11r AKMs, after which the legacy clients can successfully associate with 802.11r enabled WLANs.
Another workaround is to have two SSIDs with the same name but with different security settings (FT and non-FT).
- Bring Your Own Device (BYOD) is a concept that allows users to connect, register, and provision their own personal devices onto the corporate network. With this release, the controller supports the following while working in conjunction with the Cisco Identity Services Engine (ISE) in either Local or FlexConnect Mode (both central and local switching with central authentication).
– Device registration and supplicant provisioning
– Onboarding personal devices (provisioning for iOS or Android devices)
You can configure the following in the Advanced tab of the WLAN configuration page:
– DHCP Profiling under Client Profiling
Note RADIUS NAC with Layer3 web authentication security (local web authentication) is not supported.
Note Flex local switching with Radius NAC support is added in Release 7.2.110.0. It is not supported in 7.0 Releases and 7.2.103 Release. Downgrading 7.2.110.0 and later releases to either 7.2 or 7.0 releases will require you to reconfigure the WLAN for Radius NAC feature to work.
- When a client tries to associate with a WLAN, it is possible to determine the client type from the information received in the process. The controller acts as the collector of the information and sends the ISE with the required data in an optimal form.
The controller can be configured to act as a collector for client profiling and interact with the DHCP thread along with the RADIUS accounting task that is running on the controller. The controller receives a copy of the DHCP request packet sent from the DHCP thread and parses the DHCP packet for two options:
– Option 12—HostName of the client
– Option 60—The Vendor Class Identifier
After this information is gathered from the DHCP_REQUEST packet, a message is formed by the controller with these option fields and is sent to the RADIUS accounting thread, which is in turn transmitted to the ISE in the form of an interim accounting message.
- External web authentication is supported on FlexConnect locally switched WLANs. Local switching is enabled for packets that are destined to the external server at the access point itself. FlexConnect ACLs need to be pushed to FlexConnect access points to match the traffic and allow it to be locally switched. When a client associates with a WebAuth-enabled locally switched WLAN, the AP searches the appropriate FlexConnect ACL and updates the client. The AP decides, on a per packet basis, whether the packet should be dropped or forwarded depending on the information specified in the ACL.
- You can now upgrade from an LDPE controller software to a non-LDPE controller software. For more information, see Special Notes for Licensed Data Payload Encryption on Cisco 5500 Series Wireless LAN Controllers.
Software Release Support for Access Points
Table 1-2 lists the controller software releases that support specific Cisco access points. The First Support column lists the earliest controller software release that supports the access point. For access points that are not supported in ongoing releases, the Last Support column lists the last release that supports the access point.
| Note The Cisco 3600 Access Point was introduced in 7.1.91.0. If your network deployment uses Cisco 3600 Access Points with release 7.1.91.0, we highly recommend that you upgrade to 7.2.103.0 or a later release. |
|||
-A and N: 4.1.190.1 or 5.2 or later1 |
|||
Upgrading to Controller Software Release 7.2.110.0
Guidelines and Limitations
- While a client sends an HTTP request, the Controller intercepts it for redirection to login page. If the HTTP request intercepted by Controller is fragmented, the Controller drops the packet as the HTTP request does not contain enough information required for redirection.
- If you require a downgrade from one release to another, you might lose the configuration from your current release. The workaround is to reload the previous controller configuration files saved on the backup server or to reconfigure the controller.
- It is not possible to directly upgrade to the 7.2.110.0 release from a release that is older than 6.0.182.0.
- You can upgrade or downgrade the controller software only between certain releases. In some instances, you must first install an intermediate release prior to upgrading to software release 7.2.110.0. Table 1-3 shows the upgrade path that you must follow before downloading software release 7.2.110.0.
- When you upgrade the controller to an intermediate software release, you must wait until all of the access points that are associated with the controller are upgraded to the intermediate release before you install the latest controller software. In large networks, it can take some time to download the software on each access point.
- If you upgrade to the controller software release 7.2.110.0 from an earlier release, you must also upgrade to NCS 1.1.1.24 and MSE 7.2.110.0.
- You can upgrade to a new release of the controller software or downgrade to an older release even if Federal Information Processing Standard (FIPS) is enabled.
- When you upgrade to the latest software release, the software on the access points associated with the controller is also automatically upgraded. When an access point is loading software, each of its LEDs blinks in succession.
- We recommend that you access the controller GUI using Microsoft Internet Explorer 6.0 SP1 (or later) or Mozilla Firefox 2.0.0.11 (or later).
- Cisco controllers support standard SNMP Management Information Base (MIB) files. MIBs can be downloaded from the Software Center on Cisco.com.
- The controller software is factory installed on your controller and automatically downloaded to the access points after a release upgrade and whenever an access point joins a controller. We recommend that you install the latest software version available for maximum operational benefit.
- We recommend that you install Wireless LAN Controller Field Upgrade Software for Release 1.7.0.0-FUS, which is a special AES package that contains several system-related component upgrades. These include the bootloader, field recovery image, and FPGA/MCU firmware. Installing the FUS image requires special attention because it installs some critical firmware. The FUS image is independent of the runtime image. For more information, see http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_rn_1_7_0_0.html
- Ensure that you have a TFTP or FTP server available for the software upgrade. Follow these guidelines when setting up a TFTP or FTP server:
– Ensure that your TFTP server supports files that are larger than the size of the controller software release 7.2.110.0. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the NCS. If you attempt to download the 7.2.110.0 controller software and your TFTP server does not support files of this size, the following error message appears: “TFTP failure while storing in flash.”
– If you are upgrading through the distribution system network port, the TFTP or FTP server can be on the same or a different subnet because the distribution system port is routable.
– A third-party TFTP or FTP server cannot run on the same computer as NCS because the NCS built-in TFTP or FTP server and the third-party TFTP or FTP server require the same communication port.
- When you plug a controller into an AC power source, the bootup script and power-on self-test run to initialize the system. During this time, you can press Esc to display the bootloader Boot Options Menu. The menu options for the 5500 and Flex 7500 series controllers are different than for other controller platforms.
Bootloader Menu for 5500 Series Controllers:
Bootloader Menu for Other Controller Platforms:
Enter 1 to run the current software, enter 2 to run the previous software, enter 4 (on a 5500 series controller), or enter 5 (on another controller platform) to run the current software and set the controller configuration to factory defaults. Do not choose the other options unless directed to do so.
Note See the Installation Guide or the Quick Start Guide for your controller for more details on running the bootup script and power-on self-test.
- The controller bootloader stores a copy of the active primary image and the backup image. If the primary image becomes corrupted, you can use the bootloader to boot with the backup image.
With the backup image stored before rebooting, be sure to choose Option 2: Run Backup Image from the boot menu to boot from the backup image. Then, upgrade with a known working image and reboot the controller.
- Control which address(es) are sent in CAPWAP discovery responses when NAT is enabled on the Management Interface using the following command:
config network ap-discovery nat-ip-only { enable | disable }
– enable — Enables use of NAT IP only in Discovery response. This is the default. Use this command if all APs are outside of the NAT gateway.
– disable —Enables use of both NAT IP and non-NAT IP in discovery response. Use this command if APs are on the inside and outside of the NAT gateway; for example, Local Mode and OfficeExtend APs on the same controller.
Note To avoid stranding APs, you must disable AP link-latency (if enabled) before you use the disable option for the config network ap-discovery nat-ip-only command. To disable AP link-latency, use the config ap link-latency disable all command.
- You can configure 802.1p tagging by using the config qos dot1p-tag { bronze | silver | gold | platinum } tag. For the 7.2.103.0 and later releases, if you tag 802.1p packets, the tagging has impact only on wired packets. Wireless packets are impacted only by the maximum priority level set for QoS.
- You can reduce the network downtime using the following options:
– You can predownload the AP image.
– For FlexConnect access points, use the FlexConnect AP upgrade feature to reduce traffic between the controller and the AP (main site and the branch). For more information about the FlexConnect AP upgrade feature, see the Cisco Wireless LAN Controller Configuration Guide.
Note Predownloading a 7.2.110.0 version on a Cisco Aironet 1240 access point is not supported when upgrading from a previous controller release. If predownloading is attempted to a Cisco Aironet 1240 access point, an AP disconnect will occur momentarily.
- The Cisco 5500 Series Controllers can download the 7.2.110.0 software to 500 access points simultaneously. The Cisco Flex 7500 Series Controllers can download the 7.2.110.0 software to 1500 access points simultaneously.
- Do not power down the controller or any access point during the upgrade process; otherwise, you might corrupt the software image. Upgrading a controller with a large number of access points can take as long as 30 minutes, depending on the size of your network. However, with the increased number of concurrent access point upgrades supported, the upgrade time should be significantly reduced. The access points must remain powered, and the controller must not be reset during this time.
- If you want to downgrade from the 7.2.110.0 release to a previous release, do either of the following:
– Delete all WLANs that are mapped to interface groups and create new ones.
– Ensure that all WLANs are mapped to interfaces rather than interface groups.
- After you perform these functions on the controller, you must reboot the controller for the changes to take effect:
– Enable or disable link aggregation (LAG)
– Enable a feature that is dependent on certificates (such as HTTPS and web authentication)

Special Notes for Licensed Data Payload Encryption on
Cisco 5500 Series Wireless LAN Controllers
Datagram Transport Layer Security (DTLS) is required for all Cisco 600 Series OfficeExtend Access Point deployments to encrypt data plane traffic between the APs and the controller. You can purchase the Cisco 5500 Series Wireless LAN Controller with either DTLS that is enabled (non-LDPE) or disabled (LDPE). If DTLS is disabled, you must install a DTLS license to enable DTLS encryption. The DTLS license is available for download on Cisco.com.
Important Note for Customers in Russia
If you plan to install a Cisco 5500 Series Wireless LAN Controller in Russia, you must get a Paper PAK, and not download the license from Cisco.com. The DTLS Paper PAK license is for customers who purchase a controller with DTLS that is disabled due to import restrictions but have authorization from local regulators to add DTLS support after the initial purchase. Consult your local government regulations to ensure that DTLS encryption is permitted.
The following table lists the Paper PAK licenses and their descriptions including their part numbers.
Downloading and Installing a DTLS License for an LDPE Controller
Step 1 Download the Cisco DTLS license.
a. Go to the Cisco Software Center at this URL:
https://tools.cisco.com/SWIFT/LicensingUI/Home
b. On the Product License Registration page, choose Get New > IPS, Crypto, Other Licenses.
c. Under Wireless, choose Cisco Wireless Controllers (2500/5500/7500/8500/WiSM2) DTLS License.
d. Complete the remaining steps to generate the license file. The license file information will be sent to you in an e-mail.
Step 2 Copy the license file to your TFTP server.
Step 3 Install the DTLS license. You can install the license either by using the controller web GUI interface or the CLI:
Management > Software Activation > Commands > Action : Install License
license install tftp ://ipaddress /path /extracted-file
After the installation of the DTLS license, reboot the system. Ensure that the DTLS license that is installed is active.
Upgrading from an LDPE to a Non-LDPE Controller
In 7.0.230.0 and 7.2.110.0 controller releases, you can upgrade from an LDPE controller software to a non-LDPE controller software. For all other releases, you must first upgrade to a release that supports LDPE before you upgrade to a non-LDPE controller software.
Note If you have a 7.2.103.0 release of the controller software, it is not possible to upgrade from an LDPE to a non-LDPE controller software.
Step 1 Download the non-LDPE software release:

Safety Information
Follow the guidelines in this section to ensure proper operation and safe use of the controllers and access points.
FCC Safety Compliance Statement
FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.
Safety Precautions
For your safety, and to help you achieve a good installation, read and follow these safety precautions. They might save your life!
1. If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type of antenna you are about to install.
2. Select your installation site with safety as well as performance in mind. Electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
3. Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.
4. Plan your installation carefully and completely before you begin. Successfully raising a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
5. When installing an antenna, remember:
b. Do not work on a wet or windy day.
c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or jacket.
6. If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer: you!
7. If any part of an antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely.
8. If an accident should occur with the power lines, call for qualified emergency help immediately.
Installation Instructions
See the appropriate quick start guide or hardware installation guide for instructions on installing controllers and access points.
Note To meet regulatory restrictions, all external antenna configurations must be installed by experts.
Personnel installing the controllers and access points must understand wireless techniques and grounding methods. Access points with internal antennas can be installed by an experienced IT professional.
The controller must be installed by a network administrator or qualified IT professional, and the proper country code must be selected. Following installation, access to the controller should be password protected by the installer to maintain compliance with regulatory requirements and ensure proper unit functionality.
