Cisco Unified Wireless Network Software
Release 4.0.197.0
Release 4.0.197.0
Q.
What are the features of the Cisco Unified Wireless Network Software Release
4.0.197.0?
A.
Remote access points in a Hybrid Remote-Edge Access Point (REAP) architecture expand
from three to eight. Hybrid REAP capabilities introduced with Cisco Unified Wireless Network
Software Release 4.0 allow remote deployment of the Cisco Aironet 1240 AG Series and
Aironet 1130 AG Series Access Points from the WLAN controller, making them ideal for
branch-office and small retail locations. Hybrid REAP capabilities help IT managers centrally
control Service Set Identifiers (SSIDs), security parameters, and software loads, facilitating
unified, enterprisewide WLAN services. With Cisco Unified Wireless Network Software
Release 4.0.194.0, Hybrid REAP capabilities have been expanded to support up to eight
lightweight access points.
●
Number of location probes per client increased from four to eight—Increasing the
number of location probes per client increases location accuracy.
●
Transparent authentication server support—Customer-specific 802.1X architecture
(not public) is supported.
●
Client redirect based on RADIUS response attributes—An interim redirection step
between authentication success and full access is supported to allow, for example, the user
to be prompted to change the password or download a specific file after authentication but
before full access.
●
Basic multicast roaming support—Multicast roaming through Internet Control Message
Protocol (ICMP) messages to rejoin multicast groups after handoff is supported. The data
path for multicast traffic would thus go directly from source to destination, while unicast
traffic follows the Lightweight Access Point Protocol (LWAPP) path through the anchor
controller to facilitate in fast handoffs.
●
Multiple WLANs with the same SSID—Multiple WLANs can now share the same SSID.
This feature is useful in scenarios where different Layer 2 security policies may be used on
different WLANs but the same SSID is desired across all. Note that the fundamentals of
WLAN security policies remain unchanged—for example, there is only one Layer 2 and
Layer 3 security policy, WLANs cannot appear to advertise overlapping security policies (no
mixing of static and dynamic Wired Equivalent Privacy [WEP], although Wi-Fi Protected
Access [WPA] and WPA2 ciphers and authenticated key management [AKM] can be
mixed), and only one VLAN is allowed per WLAN.
●
Support for disabling RADIUS accounting on a per-WLAN basis—Prior RADIUS
accounting activation and disable options were on a systemwide basis. These options can
now be configured on a WLAN basis.
