Before you use a Cisco AP802 series lightweight access point with Cisco Wireless Release 8.1.111.0, you must upgrade the software in the Cisco 880 Series ISRs to Cisco IOS 15.1(4)M or later releases.
The following Cisco Wireless Controller platforms are not supported:
The Cisco Aironet 1850 Series Access Points are supported.
The Cisco Aironet 1850 Series, which is ideal for small and medium-sized networks, delivering optimal performance for enterprise and service provider markets via enterprise-class 4x4 MIMO, four-spatial-stream access points (APs) that support the IEEE’s new 802.11ac Wave 2 specification. The Cisco Aironet 1850 Series extends support to a new generation of Wi-Fi clients, such as smart phones, tablets, and laptops that have integrated 802.11ac Wave 1 or Wave 2 support.
The following features are supported:
Note Link Aggregation is not supported on Port Aggregation Protocol (PAgP).
For more information about 802.11ac Wave 2, MU-MIMO, and ECBF, see the 802.11ac section in the Cisco Wireless Controller Configuration Guide.
For more information about link aggregation for Cisco Aironet 1850 Series APs, see the Configuring Link Aggregation chapter in the Cisco Wireless Controller Configuration Guide.
The QoS Mapping feature maintains the QoS policies in situations where appropriate QoS markings that match the application type are not marked by clients or applications. The administrator gets to map the differentiated services code point (DSCP) to user priority (UP) values in a Cisco WLC, which in turn provides better experience to the users while using certain applications such as voice or video applications.
For more information about QoS Mapping, see the QoS Mapping section in the Cisco Wireless Controller Configuration Guide.
Linux Kernel-based Virtual Machine (KVM) support is added for Cisco Virtual Wireless Controller. For more information, see:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-1/KVM/b_CUWN8-1-vWLC-Deployment-Guide-using-LinuxKVM.html.
Cisco Lightweight Access Points that were manufactured over 10 years ago may fail to create a CAPWAP or LWAPP connection due to certificate expiration. You may allow the Access Points with Manufactured Installed Certificates (MICs) or Self-signed Certificates (SSCs) beyond their expiration date to associate with Cisco WLC.
On Cisco WLCs, the AP lifetime-check parameter is enabled by default. After upgrading, we recommend that you configure the Cisco WLC to ignore the expiration date on the APs’ MICs and SSCs by entering this command:
When the config ap cert-expiry-ignore { mic | ssc } enable command is entered, Cisco WLC ignores the expiration date on the APs' MICs or SSCs, allowing APs or Cisco WLCs with certificates that are more than 10 years old to connect with each other. The AP lifetime-check parameter must remain enabled as long as APs with expired MICs or SSCs are managed by this Cisco WLC.
To view the configuration state, enter this command:
For more information, see http://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63942.html.
Cisco Universal Small Cell (USC) 8x18 Dual-Mode Module is an external module (4G/LTE) that can be plugged into the Cisco Aironet 3600I APs or Cisco Aironet 3700I APs. You can configure VLAN tagging for the external module’s traffic.
For more information about the Cisco USC 8x18 Dual-Mode Module, see: http://www.cisco.com/c/en/us/support/wireless/universal-small-cell-8000-series/tsd-products-support-series-home.html.
For more information about configuring the Cisco USC 8x18 Dual-Mode Module, see the Cisco Universal Small Cell 8x18 Dual-Mode Module section in the Cisco Wireless Controller Configuration Guide.

Note If you downgrade from a Cisco WLC release that supports new mobility to a Cisco WLC release that does not support new mobility, for example, Cisco Wireless Release 7.6 to Release 7.3.x and you download the 7.6 configuration file with new mobility in enabled state, the release that does not support new mobility will have the new mobility feature in enabled state.
Note In case of FlexConnect VLAN mapping deployment, we recommend that the deployment be done using FlexConnect groups. This allows you to recover VLAN mapping after an AP rejoins the Cisco WLC without having to manually reassign the VLAN mappings.
Note The FUS image installation process reboots the Cisco WLC several times and reboots the runtime image. The entire process takes approximately 30 minutes. We recommend that you install the FUS image in a planned outage window.
Note 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 Release 1.9.0.0 of Cisco Wireless LAN Controller FUS. This is not required if you are using other controller hardware models.
Note Bootloader upgrade is not required if FIPS is disabled.
Note Microsoft Internet Explorer 8 might fail to connect over HTTPS because of compatibility issues. In such cases, you can explicitly enable SSLv3 by entering the config network secureweb sslv3 enable command.
– Ensure that your TFTP server supports files that are larger than the size of Cisco WLC software Release 8.1.111.0. 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 8.1.111.0 Cisco WLC software and your TFTP server does not support files of this size, the following error message appears:
– If you are upgrading through the distribution system network port, the TFTP or FTP server can be on the same subnet or a different subnet because the distribution system port is routable.
