Chapter6 Configuring Radio Settings
Configuring the Role in Radio Network
Note When you enable the role in the radio network as a Bridge/workgroup bridge and enable the interface
using the no shut command, the physical status and the software status of the interface will be up only
if the the device on the other end access point or bridge is up. Otherwise, only the physical status of the
device will be up. The software status of the device comes up only when the device on the other end is
configured and up.
Universal Workgroup Bridge Mode
When configuring the universal workgroup bridge roll, you must include the client MAC address. The
workgroup bridge will associate with this MAC address only if it is present in the bridge table and is not
a static entry. If validation fails, the workgroup bridge associates with its BVI MAC address. In universal
workgroup bridge mode, the workgroup bridge uses the Ethernet client MAC address to associate with
Cisco or non-Cisco root devices. The universal workgroup bridge is transparent and is not managed.
Note The universal workgroup bridge role supports only one wired client.
You can enable a recovery mechanism and make the workgroup bridge manageable again by disabling
the Ethernet client, causing the universal workgroup bridge to associate with an access point using its
own BVI address.
A roaming keyword has been added to the world-mode command to support an “airline flying between
different countries” scenario. The keyword causes the workgroup bridge to do passive scanning once it
is deathenticated from a root access point. See the “Enabling and Disabling World Mode” section on
page 6-24 for more information on this command.
Point-to-point and Multi Point bridging support for 802.11n platforms
The point-to-point and point-to-multipoint bridging is supported on the Cisco Aironet 1040, 1140, 1250
Series Access Points (802.11n platforms). The 5 GHz bands support 20- and 40-MHz and the 2.4-GHz
bands support 20 MHz.
The following items are supported for AP1040, AP1140, AP1250, and AP1260 bridging:
•MIMO, short-range bridging (on campus or inter-building bridge deployments), with dipole and
MIMO antennas (line of sight and short range) under 1 Km.
•20-MHz and 40-MHz 802.11n support.
•Workgroup bridge (WGB) short-range support.
•SISO (single-in, single-out), MCS 0-7 and legacy bridge rates (802.11 a/b/g and 802.11n) using one
outdoor antenna.
Note The aforementioned support is only for short range links and is not a replacement for the
AP-1240/1300/1400 or other Bridge products.
The following are not supported by AP1040, AP1140, AP1250, and AP1260 in their bridging modes:
•The distance command. The distance command is supported only on access points approved for
outdoor use.
•Outdoor MIMO bridging using external antennas.
