® Unified Wireless Network Software Release 220.127.116.11 (7.2MR1) addresses key enterprise IT challenges related to Bring Your-Own-Device (BYOD) wireless as primary access and architectural complexity. Release 18.104.22.168 delivers 802.11r fast roaming with BYOD enhancements for onboarding personal devices to allow users to connect, register and provision their own personal devices on the corporate network. This release also introduces the Cisco Aironet
® 1552i and 1552s Access Points, the newest members of the 1550 Series 802.11n outdoor access points.
A number of new features are included in Cisco Unified Wireless Network Software Release 22.214.171.124. The features are supported in the following platforms:
• Cisco Aironet access points running Control and Provisioning of Wireless Access Points (CAPWAP) Protocol
• Cisco 2500 and 5500 Series Wireless LAN Controllers
• Cisco 7500 Series FlexConnect Wireless LAN Controller
• Cisco Catalyst® 6500 Series Wireless Services Module 2 (WiSM2)
• Cisco Wireless LAN Controller Module for Integrated Services Routers G2 (WLCM2) (Cisco Wireless LAN Controller on Cisco Services Ready Engine)
• Cisco 3300 Series Mobility Services Engine (MSE)
• Cisco Network Control System (NCS) 1.1
Cisco Wireless LAN Controllers: New Features
In Software Release 126.96.36.199, Cisco Wireless LAN Controllers continue to provide solutions with architectural flexibility to enable wireless as primary access and simplify deployments for BYOD. Table 1 describes the new features of the wireless controller in this release.
Table 1. New Controller Features in Cisco Unified Wireless Network Release 188.8.131.52
IEEE Standard for fast roaming (802.11r) in local mode
Introduces a new concept of roaming where the handshake with the new access point is done even before the client roams to the target access point.
Fast roaming with 802.11r can allow clients to move between access points without breaking a session, a critical requirement for many applications. Cisco led the effort to evolve Cisco Centralized Key Management into the 802.11r standard and is now leading again by being first to support this standard.
BYOD enhancements in conjunction with Cisco Identity Services Engine (ISE)
Local mode and FlexConnect support for device registration and supplicant provisioning, and provisioning and onboarding of personal devices.
These enhancements allow users to connect, register, and provision their own personal devices on the corporate network.
Device profiling with Cisco Dynamic Host Control Protocol (DHCP) sensor
The WLC will act as the "collector"of DHCP options in DHCP packetsand feed the external "analyzer"(the Cisco ISE) with the required data via an interim accounting message.
Device profiling makes it possible to determine a device's type from the information received from the device during its connection to the network.
External web authentication for FlexConnect local switched clients
Web authentication is a Layer 3 security feature that causes the controller to not allow IP traffic (except DHCP and DNS -related packets) from a particular client until that client has been validated. Web authentication is a simple authentication method that does not require the use of a supplicant or client utility. The login page used for web authentication is stored on an external web server.
Web authentication provides architectural flexibility by extending web authentication mechanisms available in local mode to FlexConnect local switched clients.
Platform support for Cisco Integrated Services Router Generation 2 (ISR G2) and embedded access point router
Support for Cisco WLCM2 on SRE for ISR G2 and the embedded Cisco 802.11n access point router with built-in a/g/n access point.
This feature helps to maintain architectural flexibility with ISR integrated wireless in the branch.
Cisco Aironet Access Points: New Features
Table 2 describes the new features of Cisco Aironet access points in this software release.
Table 2. New Access Point Features in Cisco Unified Wireless Network Release 184.108.40.206
Cisco Aironet 1552i 802.11n Outdoor Access Point
The Cisco Aironet 1552i comes with internal antennas (2.4 GHz at 2 dBi or 5 GHz at 4 dBi).
The 1552I provides an economical and esthetically pleasing option for outdoor access point deployments.
Cisco Aironet 1552s 802.11n Outdoor Access Point
The Cisco Aironet 1552s integrates an ISA100.11a gateway for sensor network data transport over 802.11n wireless network
The 1552s combines two separate wireless networks into a single, integrated solution, reducing installation costs for industrial deployments.
Additional modes for supporting outdoor wired root access points (RAP)
Prior to Release 220.127.116.11, outdoor access points, including Cisco Aironet 1520 and 1550 Series, could work only in bridge mode as RAP or mesh access points MAP. With this release, the 1520 and 1550 Series support local, bridge, and FlexConnect modes.
This release enhances the features and deployment flexibility available for outdoor access points with support for nonbridged modes.
Cisco Mobility Services Engine (MSE) offers service plane separation for scalable services delivery and a single point of interface to securely expose network intelligence to third-party applications. In Release 18.104.22.168, a larger number of MSEs can be managed per instance of Cisco Prime
™ Network Control System (NCS).
Table 3 describes the new features specific to the Cisco Mobility Services Engine with Cisco Unified Wireless Network Software Release 22.214.171.124.
Table 3. New Cisco Mobile Services Engine Features in Cisco Unified Wireless Network Release 126.96.36.199
Enhanced scale for managing MSE deployments via Cisco Prime Network Control System (NCS)
Previous to Release 188.8.131.52, the maximum number of MSEs per instance of NCS was 10.
The maximum has now increased to 25 MSEs per NCS.
Ease of MSE management for large deployments.
