Cisco Cisco Wireless Services Module 2 (WiSM2) Notas de publicación

Primary Boot Image.................. 7.5.102.0

Backup Boot Image................... 7.3.112.0 (default) (active)

After the reboot, press Esc on the console, and use the boot menu to select Release 7.5.

After booting on Release 7.5, set back the primary boot, and save the configuration by entering 
the following command:

config boot primary

When FlexConnect access points (known as H-REAP access points in the 7.0.x releases) 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 7.5.102.0 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. The 
workaround is to upgrade from 7.0.240.0 or a later 7.0.x release to the 7.5.102.0 release.

If you have disabled the ‘learn-ip-address' functionality for locally switched WLANs with the 
security type configured as ‘WEB-AUTH’ or ‘DHCP-Req’ or if PMIPv6 is in enabled state and you 
upgrade to Release 7.5.102.0, the ‘learn-ip-address’ feature is enabled after you upgrade. This is to 
avoid the WLAN from being disabled in Release 7.5.102.0 because of changes committed for 
CSCuf24517. The IP-based functionality might be impacted if the ‘learn-ip-address’ feature is 
disabled in Release 7.5.102.0 due to changes committed for CSCuf24517.

In Release 7.5.102.0, when the WLAN is locally switched, you must use the config wlan 
flexconnect learn-ipaddr wlan-id {enable | disable} command. When the WLAN is centrally 
switched, you must use the config wlan learn-ipaddr-cswlan wlan-id {enable | disable} command.

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.

A client whose home page is an HTTPS (HTTP over SSL, port 443) one is not redirected by Web 
Auth to the web authentication dialog box. Therefore, it is not possible for such a client to get 
authenticated and eventually fails to connect to the network. A workaround is for the client to 
attempt to open any HTTP (port 80) web page.

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 Flex 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.
