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 7.4.100.0 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 7.4.100.0 release.

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.

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 

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 LAN 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 

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.

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 7.4.100.0 release from a release that is older than 
7.0.98.0.

These access points are supported in the separate 4.1.19x.x mesh software release or with 
release 5.2 or later releases. These access points are not supported in the 4.2, 5.0, or 5.1 
releases.

The access point must always be connected to the POE-IN port to 

associate with the controllers. The POE-OUT port is for 
connecting external devices only.
