What’s New in This Release
Support for –B Domain
The FCC (USA) rule making on 5 GHz released on April 1, 2014, (FCC 14-30 Report and Order) goes into effect for products that are sold or shipped on or after June 2, 2016. Cisco APs and Cisco WLCs will comply with the new rules by supporting the new regulatory domain (–B) for the US and will create new AP SKUs that are certified under the new rules. Examples of new rules include new 5-GHz band channels permitted for outdoor use, and transmission (Tx) power level increased to 1W for indoor, outdoor, and point-to-point transmissions.
Note Cisco APs and Cisco WLCs that are in the –A domain category can continue to operate and even coexist with –B domain devices without any issues.
We recommend that you upgrade Cisco APs and Cisco WLCs to the appropriate software release that supports –B domain.
Software Release Support for Access Points
Table 1 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. |

Upgrading to Controller Software Release 7.4.150.0
Guidelines and Limitations
– Functionality prior to Release 7.4.130.0—If a WLAN was added to an AP group prior to Release 7.4.130.0, the RF radio policy is set to All after an XML upload/download. This is because the default value of RF policy was not added. This issue was addressed through CSCud37443. However, this corrects only the newly created WLAN-AP group associations and not the previous ones. Therefore, if you have configured a WLAN-AP group association prior to Release 7.4.130.0, you must remove the WLAN from the AP group and add it again in Release 7.4.130.0 or a later release.
Also, the XML configuration for radio policy was not present in releases prior to 8.0. This issue is addressed through CSCul59089.
– Change in functionality with Release 7.4.130.0—The RF radio policy is by default set to None for all WLAN-AP group associations created in Release 7.4.130.0. Any previous WLAN-AP group associations that are carried over will continue to be set to All unless a WLAN is removed from the AP group and added again.
The XML upload/download for AP group RF radio policy is available only from Release 8.0.
- Cisco WLCs validate client IP address at the time of learning, using the dynamic interface IP address as per the VLAN assigned to the client. Ensure that the clients and the dynamic interface VLAN of the clients are on the same subnet, even if DHCP proxy is disabled at the Cisco WLC.
- When H-REAP access points that are associated with a controller that has all the 7.0.x software releases that are prior to 7.0.240.0 upgrade to the 7.4.150.0 release, the access points lose their VLAN support configuration if it was enabled. The VLAN mappings revert to the default values of the VLAN of the associated interface. This issue does not occur if you upgrade from 7.0.240.0 or later 7.0.x release to the 7.4.150.0 release.
- We recommend that you install Wireless 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.
- If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Wireless Controller Field Upgrade Software for Release 1.8.0.0-FUS. This is not required if you are using other controller hardware models. For more information, see http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_1_8_0_0.html.
- When you enable LAG on a Cisco 2500 Series Controller with which a direct-connect access point is associated, the direct-connect access point dissociates with the controller. When LAG is in enabled state, the direct-connect access points are not supported. For direct-connect access points to be supported, you must disable LAG and reboot the controller.
If LAG is enabled on the Cisco 2500 Series Controller and the controller is downgraded to a non-LAG aware release, the port information is lost and it requires manual recovery.
- After you upgrade to the 7.4 release, networks that were not affected by the existing preauthentication ACLs might not work because the rules are now enforced. That is, networks with clients configured with static DNS servers might not work unless the static server is defined in the preauthentication ACL.
- On 7500 controllers if FIPS is enabled, the reduced boot options are displayed only after a bootloader upgrade.
Note Bootloader upgrade is not required if FIPS is disabled.
- 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 7.4.150.0 release from a release that is older than 7.0.98.0.
- 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 7.4.150.0. Table 2 shows the upgrade path that you must follow before downloading software release 7.4.150.0.
- 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 7.4.150.0 from an earlier release, you must also upgrade to Cisco Prime Infrastructure 1.3 and MSE 7.4.
- 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 a later release) or Mozilla Firefox 2.0.0.11 (or a later release).
- 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.
- Ensure that you have a TFTP, FTP, or SFTP server available for the software upgrade. Follow these guidelines when setting up a server:
– Ensure that your TFTP server supports files that are larger than the size of the controller software release 7.4.150.0. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the Prime Infrastructure. If you attempt to download the 7.4.150.0 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.
- 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 differ from the menu options for the 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 a 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 a discovery response. Use this command if APs are on the inside and outside of the NAT gateway; for example, Local Mode and OfficeExtend APs are 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).
Note Predownloading a 7.4.150.0 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.
- 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 7.4.150.0 release to a 6.0 or an older 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)
– Add a new license or modify an existing license
– Increase the priority for a license
– Install vendor device certificate
– Install Web Authentication certificate

Special Notes for Licensed Data Payload Encryption on
Cisco Wireless 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 Cisco Wireless Controllers 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 Wireless 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.
Note Paper PAKs and electronic licenses available are outlined in the respective controller datasheets.

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.
