When the wireless access point receives data packets that are not 802.3 packets,
the wireless access point must format the packets to 802.3 by 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 verify 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:
1. Enter global configuration mode.
configure terminal
2. 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.

3. Set the encapsulation transformation method to RFC 1042 (
the default setting) or 802.1h (

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 access point. The
default setting, disabled, reduces the reliability of multicast delivery to allow
more workgroup bridges to associate to the wireless access point.
Access points and bridges normally treat workgroup bridges 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 access point reliably
delivers multicast packets, including Address Resolution Protocol (ARP) packets,
to the workgroup bridge.
