Table 2 describes the new features of the wireless controllers in this release.
Table 2. New Controller Features
DNS-Based (FQDN) ACLs for Clients in the Registration Phase of Onboarding
For BYOD onboarding use cases, IT administrators can set pre-authentication ACLs to restrict the sites that devices have the permission to visit prior to authentication. Registering BYOD devices may need to connect to the Internet for either downloading the supplicant software for registration or validating the device for connection to the Wi-Fi network.
Allow the client to access the proper resource (apple.com or play.google.com typically) without a broad IP-based ACL. With DNS-based ACLs, the client, when in registration phase, will be allowed to connect to the configured URLs.
Apple iOS7 Captive Portal Support
With iOS7, Apple has enhanced the Captive Network Assistant (CNA) to make it more robust. Cisco Wireless Release 7.6 includes associated changes to interoperate with Apple's new implementation.
The wireless LAN controller can detect and respond to pre-iOS7 Captive and iOS7-based changes to CNA, providing a seamless experience for all clients.

The new protocol pack to be delivered with Release 7.6 includes Microsoft Lync 2013 and Cisco Jabber support.
Customers can detect new applications in their networks, including Jabber and Microsoft Lync 2013, and enable appropriate QoS policies for these applications.
Increased Scale for Sleeping Clients on Cisco 8500 WLC and Flex 7500 Products
For large, geo-distributed deployments with the 8500 WLC and Flex7500, the number of sleeping clients that are remembered is increased from 9000 clients to 25,000 clients.
A larger number of sleeping clients are remembered, even after waking up on the wireless network with high-scale controllers. This eliminates the need for user intervention to re-enter credentials for a greater number of clients.
Automatic Recovery of Primary and Standby Controllers in Stateful Switchover High-Availability Deployment from Maintenance Mode After the Network Re-converges
The standby controller will automatically recover from maintenance mode when:
• The management default gateway is not reachable
• The peer redundancy port is not reachable
• The standby WLC, which has never paired up with the primary WLC, boots up first
Prior to Release 7.6, when a wireless LAN controller enters into maintenance mode due to a network outage, IT administrators were required to manually pair the controllers back after the network issue was addressed.
In order to address and simplify this problem, enhancement is added in 7.6 to automatically recover.
Ethernet Fallback Shutdown for Access Points in Cisco FlexConnect Mode
With this feature enabled, if the access point has power, but its Ethernet interface is disconnected, the radios will shutdown.
Clients can connect to other adjoining access points with connectivity to the wired network over the Ethernet port.
China -H Domain Support
Expanded China 5 GHz spectrum is now approved for indoor use (5150 to 5350 MHz). This is in addition to the existing 5720 to 5850 MHz range.
Support for new channels with a new domain, H, is enabled for China. The older domain, C, is still used by Pakistan and Malaysia.
Support for Secure LDAP Communication
The connection between the wireless controller and LDAP external server can be secured with Transport Level Security (TLS).
In addition to authenticated access to the LDAP server, encryption provides enhanced security for limiting denial-of-service (DoS) attacks and to validate the source of the query.
Enhancements for Radius Accounting and Authentication
Call Station ID Type can be set for Authentication (like in 7.5) and also for Accounting (new in 7.6). In addition, Call Station ID type can be set to new values such as access point Ethernet Mac Address and access point Ethernet Mac Address: SSID.
Additional flexibility for RADIUS information about the source of the RADIUS request is available.
Flexible EAP Timers for External RADIUS
The timers allow for activation of EAP values on a per- WLAN basis, and override global configuration.
Customers can have specific WLANs for specific devices, and require different EAP timers and retries for these WLANs.
