Configuring the Ethernet Encapsulation Transformation Method
Use the dot11 extension aironet command to enable Aironet extensions if they are disabled.
Configuring the Ethernet Encapsulation Transformation Method
When the wireless device receives data packets that are not 802.3 packets, the wireless device must
format the packets to 802.3 using an encapsulation transformation method. These are the two
transformation methods:
• 802.1H—This method provides good performance for Cisco Aironet wireless products.
• RFC 1042—Use this setting to ensure good interoperability with non-Cisco Aironet wireless
equipment. RFC 1042 is used by other manufacturers of wireless equipment and is the default
setting.

Beginning in privileged EXEC mode, follow these steps to configure the encapsulation transformation
method:
Enabling and Disabling Reliable Multicast to Workgroup
Bridges
The Reliable multicast messages from the access point to workgroup bridges setting limits reliable
delivery of multicast messages to approximately 20 Cisco Aironet Workgroup Bridges that are
associated to the wireless device. The default setting, disabled, reduces the reliability of multicast
delivery to allow more workgroup bridges to associate to the wireless device.
Access points and bridges normally treat workgroup bri
dges not as client devices but as infrastructure
devices, like access points or bridges. Treating a workgroup bridge as an infrastructure device means that
the wireless device reliably delivers multicast packets, including Address Resolution Protocol (ARP)
packets, to the workgroup bridge.
Step 3

Command Purpose
configure terminal Enter global configuration mode.
interface dot11radio {0 | 1}
Enter interface configuration mode for the radio interface. The
2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
The 802.11n 2.4-GHz radio is radio 0
The 802.11n 5-GHz radio is radio 1.
