Feature Description for Cisco IOS Software Release 12.4(3G)JA

Cisco Aironet Access Points

The Cisco Aironet flagship access points-the Cisco Aironet 1240AG Series and the Cisco Aironet 1130AG Series-are now available in single-band 802.11g versions for use in regulatory domains that do not allow 802.11a (5-GHz) operation.
The Cisco Aironet 1240G Series Access Points provide single-band 802.11g wireless connectivity for challenging RF environments such as factories, warehouses, and large retail establishments (Table 2).

Regulatory Domain Update for Japan

This release supports the U regulatory domain for the W52 frequency set (channels 36, 40, 44, and 48) in Japan. Cisco access points specified for this new domain ship with a U domain radio. Installed J domain access points are automatically upgraded to U domain status with this release. For the latest Cisco WLAN compliance status, please visit: http://www.cisco.com/application/pdf/en/us/guest/products/ps5861/c1650/cdccont_0900aecd80537b6a.pdf.

Management Frame Protection

Wireless Intrusion Detection System (IDS)-Management Frame Protection (MFP), which provides for the authentication of 802.11 management frames by the wireless network infrastructure, was introduced with Cisco IOS Software Release 12.3(8)JA. This release enhances MFP support and is now available for Cisco Aironet 802.11a/b/g CardBus Wireless LAN Client Adapters, Wireless PCI Adapters, and Autonomous Access Points running in root, repeater, workgroup bridge, and non-root bridge mode. MFP adds security to the MAC management layer of 802.11 connectivity by cryptographically hashing the management frames and generating a Message Integrity Check (MIC) during network connection. This release allows a Cisco Aironet 802.11a/b/g CardBus Wireless LAN Client Adapter or Wireless PCI Adapter to detect a spoofed management frame at the first instance of an attack and generate an intrusion detection system (IDS) alert to the device interface. Autonomous access points that detect a spoofed management frame from a client or another access point will also generate an IDS alert that is sent to the Cisco Wireless LAN Solution Engine (WLSE), as shown in Figure 2. In order to take advantage of the MFP, the clients must support Cisco Compatible Extensions Version 5 devices. For more details, see the Cisco Compatible Extensions program Webpage at: http://www.cisco.com/go/ciscocompatible/wireless

Multiple VLAN and Rate-Limiting Support for Wireless Bridges

This feature provides the Cisco Aironet wireless LAN bridges the ability to provision each non-root under one VLAN. This could be supported by simply adding the 802.1Q tag with the configured VLAN ID to all the uplink packets coming from the Ethernet side of the non-root bridge. Cisco Aironet wireless bridges provide control in limiting the data traffic pumped through the air. This feature makes it possible to control the maximum rate of traffic transmitted or received on an interface. The actual action of limiting the data rate is done at Layer 3 before the traffic data is provided to the radio.
In order to implement rate limiting, the Cisco IOS Class-based Policing feature is used. You can find more details about this feature at the following link:

Channel Scan Limitation for Workgroup Bridge

This feature reduces the total scanning time and hand-off delay as a workgroup bridge roams from one access point to another. With this feature, the workgroup bridge can be configured to scan only one or a limited subset of channels instead of scanning all possible channels.

Universal Workgroup Bridge Support for One Ethernet Client

This feature allows one Ethernet client to connect through a Cisco autonomous access point configured as a workgroup bridge to non-Cisco access points. When configured for universal workgroups bridge support, the access point uses the MAC address of the Ethernet client to associate with the non-Cisco access points. All probe and association requests will be sent and received using the MAC address of the Ethernet client instead of the dot11 MAC. As a result, the root (non-Cisco) access point will not be able to use telnet to manage the workgroup bridge, because it can only read the single MAC address of the connected Ethernet client, and it uses this MAC address to forward any traffic to the workgroup bridge.
