For detailed instructions on predownloading AP images, see the Predownloading an Image to an Access Point section in the Cisco Wireless Controller Configuration Guide.
Note There is no change in the downgrade procedure.
Plug and play (PnP) to configure Cisco APs using Cisco Application Policy Infrastructure Controller (APIC) Enterprise Module (Cisco APIC-EM) is supported on the following Cisco APs in FlexConnect mode and Local mode:
This feature helps you to provision in advance, the AP details from a central service (APIC-EM) and eases the steps that are to be performed by a local installer.
At the center of Apple and Cisco collaboration is a unique handshake between Cisco WLAN and iOS 10 beta Apple devices. This handshake enables Cisco WLAN to provide an optimal Wi-Fi roaming experience to Apple devices. Additionally, Cisco WLAN trusts Apple devices and gives priority treatment for business-critical applications specified by the Apple device.
This feature is supported on all Cisco WLC platforms.
For more information, see the following sections in the Cisco Wireless Controller Configuration Guide :
The Apple and Cisco collaboration positively impacts Apple device users and IT administrators:
Cisco CMX Cloud Connector provides the ability to send NMSP data seamlessly and securely from Cisco WLC to Cisco CMX Cloud over HTTPS. This enables the delivery of Wi-Fi location-based services including Analytics, from cloud without the need to install and manage Cisco CMX Cloud proxy on the premises. For more information about Cisco CMX Cloud, go to http://support.cmxcisco.com/.
Note To avoid duplication of data, the maximum number of NMSP connections on the Cisco WLC are limited to three connections. There are a maximum of two incoming TCP/TLS connections from MSE and CMX to WLC, and one outgoing HTTPs connection to CMX Cloud.
For more information, see the CMX Cloud Connector section in the Cisco Wireless Controller Configuration Guide.
The Client Troubleshooting tool on Cisco WLC helps a network administrator to troubleshoot clients and get insights into client behavior in real time. This is an on-demand tool that provides features such as packet captures, ping test, connection analysis, and event log.
Domain Filtering allows network administrators to define HTTP URL-based Access Control Lists (ACL) in order to allow or disallow traffic.
The URL Filtering feature helps optimize network bandwidth utilization by restricting access to websites. This feature gives you control to build URL ACLs using which you can either permit or deny access to websites. These ACLs can be applied to locations, AP groups, WLAN profiles, and trusted and non-trusted clients within the same SSID.
For information, see the Configuring URL Filtering section in the Cisco Wireless Controller Configuration Guide.
Default FlexConnect Group is a container where FlexConnect APs, which are not part of an administrator-configured FlexConnect group, are added automatically when they associate with Cisco WLC. It is not possible to manually add or delete the default FlexConnect group. It is also not possible to manually add or delete APs to the default FlexConnect group.
For more information, see the Default FlexGroup section in the Cisco Wireless Controller Configuration Guide.
Support is added for client IPv6 traffic and IPv6 address format for the EoGRE tunnel gateway. Client IPv6 traffic is supported on both IPv4 and IPv6 EoGRE tunnels. A maximum of eight different client IPv6 addresses are supported. Cisco WLCs send all the client IPv6 addresses that they have learned to the Accounting server in the accounting update message. All RADIUS or Accounting messages that are exchanged between Cisco WLCs and tunnel gateways or RADIUS servers are outside the EoGRE tunnel.
Note IPv6 is not supported on the FlexConnect-to-WAG EoGRE tunnel.
For more information, see the Ethernet over GRE Tunnels section in the Cisco Wireless Controller Configuration Guide.
Mesh APs will periodically go off channel and scan all the channels to update neighbor lists.
Support is added for permanent off-channel background scanning for mesh APs (MAPs) when fast or very fast convergence is configured, to take advantage of the presence of neighboring MAPs that have been heard outside the Subset Channel list.
Support is added for NBAR2 Protocol Pack 19.1.0 for Cisco WLCs, which will be the default protocol pack PP for Release 8.3. The AP protocol pack is upgraded to NBAR2 Protocol Pack 14.
For more information, see Release Notes for NBAR2 Protocol Pack 19.1.0 for Cisco Wireless Controllers.
OfficeExtend mode allows remote AP to connect to home or remote site broadband Internet access and establish a secure tunnel to the corporate network. This enables remote employees to access data, voice, video, and cloud services for a mobility experience that is consistent with the experience in a corporate office.
It is possible to enable both RADIUS NAC and WPA/WPA2-PSK on a WLAN. Prior to Release 8.3, it was not possible to enable both of these configurations on the same WLAN.
To have web redirect with PSK on Cisco WLCs for device onboarding. For example, onboard devices using an SSID with a PSK, send the MAC address to Cisco ISE using central web authentication (CWA), and determine if it is registered.
For more information, see the Enabling RADIUS NAC on a WPA and WPA2-PSK WLAN section in the Cisco Wireless Controller Configuration Guide.
Link Layer Discovery Protocol (LLDP) is added to the recovery image of Cisco IOS APs. LLDP is a vendor-neutral data-link-layer protocol, used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 LAN, mainly wired Ethernet. As protocol runs over the data-link layer, it allows two systems running different network layer protocols to learn about each other. Therefore, the protocol allows interoperability between Cisco devices and non-Cisco devices.
It is now possible to assign EoGRE tunnel profiles to WLANs configured for Internal WebAuth and WPA2-PSK. WLANs configured with WPA2-PSK/WPA2-802.1X and Internal WebAuth are also supported. Prior to Release 8.3.102.0, only WLANs configured for Open and WPA2-802.1X were supported.
Cisco Wireless Release 8.3 provides an enhancement to broadcast traffic support on multiple 802.1Q VLAN workgroup bridge (WGB) deployments that traverse mesh networks and in Local mode; specifically, support for WGB downstream broadcasts over multiple VLANs (to differentiate and prioritize traffic); and, bridging of VLAN traffic to wired clients connected to the WGB. Applications for this functionality are commonly found in the transportation and mining industries. For more information, see CSCub87583.
For more information, see the Workgroup Bridge (WGB) Downstream Broadcast On Multiple VLANs section in the Cisco Wireless Controller Configuration Guide.
The –M Regulatory Domain is supported on Cisco Industrial Wireless 3700 Series APs in the following countries:
– config radius callStationIdType ap-mac-ssid-ap-group
Sets the Called Station ID type in the format < AP MAC address >:< SSID >:< AP Group > sent in the RADIUS Accounting messages
– config radius auth callStationIdType ap-mac-ssid-ap-group
Sets the Called Station ID type in the format < AP MAC address >:< SSID >:< AP Group > sent in the RADIUS Authentication messages.
Cisco Hyperlocation Module software has been updated to enhance High Availability and the new –B domain for AP3702-B, along with new code updates:
Cisco Wireless Release 8.3 extends the capability to simplify access control management using Cisco TrustSec Security Groups to users connected to FlexConnect APs.
Users connected to FlexConnect APs can now be classified with a Security Group Tag (SGT) to simplify policy management. Cisco WLCs can now share Security Group membership information over an SGT eXchange Protocol (SXP) connection with switches, routers, and firewalls to simplify access control list management and firewall rule management elsewhere in the network.
To use this capability, Cisco Identity Services Engine would be required to authorize devices based on attributes such as the role of the user and/or device and assign a Security Group Tag as part of an authorization rule.
Other devices receiving SGT information over SXP can then apply Security Group Access Control Lists and group-based firewall rules, which are more flexible and much easier to manage than using IP address-based controls.
The feature complements existing support for Security Group-based policies for centrally switched user traffic in the earlier Cisco Wireless releases.
Cisco 2800 AP and 3800 AP support the XOR radio slot where the Wi-Fi radio can be switched between 2.4 GHz and 5 GHz and vice versa:
– Port type shows as GigabitEthernet when a Cisco 3800 AP is connected to a legacy Gigabit port
– Port type shows as TenGigabitEthernet when a Cisco 3800 AP is connected to an mGig port
Data based on the 2.4-GHz bands and 5-GHz bands related to an AP and a client is available in pie-chart format.
After you upgrade to Cisco Wireless Release 8.3.102.0, the 802.11k and 802.11v protocols are enabled by default on all existing WLANs, and new WLANs that you may create, because of improved feature support on Apple iOS 10. Because of these new features, third-party clients such as scanners may have issues connecting to WLAN. This could be due to some of the client types not ignoring the new information element and thereby failing to connect. As per the IEEE standards, if a client does not understand any new information element, it should ignore and still be able to connect. A better solution for this would be to work with client vendor.
The workaround, in Cisco WLC, is to disable these features on the WLAN.
Step 1 Choose WLANs > WLAN ID.
Step 2 On the WLANs > Edit page, click the Advanced tab.
Step 3 In the 11k section, uncheck all the check boxes.
Step 4 In the 11v BSS Transition Support section, uncheck the BSS Transition check box.
Step 5 Save the configuration.
Step 1 Disable 802.11k by entering these commands:
config wlan assisted-roaming neighbor-list disable wlan-id
config wlan assisted-roaming dual-list disable wlan-id
config wlan assisted-roaming prediction disable wlan-id
Step 2 Disable 802.11v by entering this command:
config wlan bss-transition disable wlan-id
Step 3 Save the configuration by entering this command:
The GLC-TE 1000BASE-T SFP module is supported in Cisco 5508 WLCs. The Cisco 5508 WLCs that have the GLC-TE SFP module must run Release 8.3 or a later release. The GLC-TE SFP module is a replacement of GLC-T, which has reached its end-of-sale date as of June 1, 2017. For more information about end-of-sale and end-of-life announcement for select Cisco 1000BASE-T SFP modules, see http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/eos-eol-notice-c51-737325.html.

– 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.
a. Enable IPv4 and DHCPv4 on the network—Load a new Cisco WLC software image on all Cisco WLCs plus Supplementary AP Bundle images on the Cisco 2504 WLC, 5508 WLC, and WiSM2 or perform a predownload of AP images on the required Cisco WLCs.
b. Reboot Cisco WLC immediately or at the preset time.
c. Ensure that all Cisco APs are associated with Cisco WLC.
d. Disable IPv4 and DHCPv4 on the network.
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.
You can upgrade directly to 8.3.102.0. Note See “Changes in Images and Installation Procedure for Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2” section about special upgrade instructions for Cisco 2504 WLC, 5508 WLC, and WiSM2. |
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 8.3.102.0. 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 8.3.102.0 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.

Click the Caveat ID/Bug ID number in the table.
The corresponding Bug Search Tool page is displayed with details of the Caveat ID/Bug ID.
The Bug Search Tool (BST), which is the online successor to the Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data, such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
To view the details of a caveat whose ID you do not have, perform the following procedure:
1. Access the BST using your Cisco user ID and password:
https://bst.cloudapps.cisco.com/bugsearch/
2. In the Bug Search window that is displayed, enter the necessary information in the corresponding fields.
For more information about how to use the Cisco Bug Search Tool effectively, including how to set email alerts for bugs and to save bugs and searches, see the Bug Search Tool Help & FAQ page.
Note The Cisco Mobility Express wireless network solution is available starting from Cisco Wireless Release 8.1.122.0.
The Cisco Mobility Express wireless network solution provides a wireless controller functionality bundled into the Cisco Aironet 1830, 1850, 2800, and 3800 Series access points. This functionality provides a simplified Wi-Fi architecture with limited enterprise-level WLAN capability to small and medium deployments.
In the Cisco Mobility Express wireless network solution, one AP, which runs the Cisco Mobility Express wireless controller, is designated as the primary AP. Other access points, referred to as Subordinate APs, associate to this primary AP.
The primary AP operates as a wireless controller, to manage and control the subordinate APs. It also operates as an AP to serve clients. The subordinate APs behave as normal lightweight APs to serve clients.
For more information about the solution, including the setup and configuration, see the Cisco Mobility Express User Guide for Release 8.3, at:
http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mob_exp/83/user_guide/b_ME_User_Guide_83.html
The following new features and functionalities have been introduced in this release:
The following are existing features, with continued support in the current release:
Note Even if the Cisco AP is 802.3ad (LACP)-compliant, link aggregation groups (LAG) are not supported on the AP while it has a Cisco Mobility Express software image.
– Supported—Over-the-Air Fast BSS transition method
– Not Supported—Over-the-DS Fast BSS transition and Fast Transition PSK authentication
