What’s New in This Release
There are no new features or enhancements in this release. For more information about the updates in this release, see the Resolved Caveats section.
Software Release Support for Access Points
Table 1-1 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.
-A and N: 4.1.190.1 or 5.2 or later1
Upgrading to Controller Software Release 7.2.115.2
Guidelines and Limitations
- 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 7.2.115.2 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 7.2.115.2. Table 1-2 shows the upgrade path that you must follow before downloading software release 7.2.115.2.
- 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 7.2.115.2 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, although not mandatory, 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 7.2.115.2. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the NCS. If you attempt to download the 7.2.115.2 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 7.2.115.2 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 7.2.115.2 software to 500 access points simultaneously. The Cisco Flex 7500 Series Controllers can download the 7.2.115.2 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 7.2.115.2 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)
– Add a new license or modify an existing license
– Increase the priority for a license
- Ensure that you apply the calibration fix for AP1260 and AP3500 models (see the resolved caveat CSCty68030). This addresses a manufacturing calibration issue on the AP1260 and AP3500 models (VID V01). For more information, see https://supportforums.cisco.com/document/105346/calibration-fix-1260-3500-series-aps-csctu24972-cscty68030

Installation Notes
This section contains important information to keep in mind when installing controllers and access points.
Warnings
Warning This warning means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground connector. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning Read the installation instructions before you connect the system to its power source. Statement 10
Warning Do not work on the system or connect or disconnect any cables (Ethernet, cable, or power) during periods of lightning activity. The possibility of serious physical injury exists if lightning should strike and travel through those cables. In addition, the equipment could be damaged by the higher levels of static electricity present in the atmosphere. Statement 276
Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364
Warning In order to comply with radio frequency (RF) exposure limits, the antennas for this product should be positioned no less than 6.56 ft. (2 m) from your body or nearby persons. Statement 339
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
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.
