Configuring the Ethernet Encapsulation Transformation Method
DETAILED STEPS
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 by using an encapsulation transformation method. These are the two
transformation methods:
•
802.1H—This method provides optimum performance for Cisco wireless products.
•
RFC 1042—Use this setting to ensure interoperability with non-Cisco wireless equipment.
RFC1042 does not provide the interoperability advantages of 802.1H but is used by other
manufacturers of wireless equipment.
To configure the encapsulation transformation method, follow these steps, beginning in privileged EXEC
mode.

Command
Purpose
Step 1
configure terminal
Enters global configuration mode.
Step 2
interface dot11radio
{
0
|
1
}
Enters interface configuration mode for the radio interface.
The 802.11g/n 2.4-GHz radio is radio 0.
The 802.11n 5-GHz radio is radio 1.
Step 3
no dot11 extension aironet
Disables Aironet extensions.
Step 4
end
Returns to privileged EXEC mode.
Step 5
