The root priority can be a value from 0 to 7. If you set the root
priority to 0, the access point can never become the root access
point. You should always set a WAPs root priority to 0.
For more information, see “About the Root Access Point” later in
this section.
IAPP Frame Type
Controls the encapsulation of Inner Access Point Protocol (IAPP)
frames sent by this access point. You can select either DIX
(Ethernet 2.0) or SNAP encapsulation. Choose SNAP if other
network computers use SNAP encapsulation for IP frames.
Ethernet Bridging
Determines how wireless frames are converted to Ethernet frames
and vice versa.
Enabled
Choose Enabled if you want frames to be forwarded
directly to the Ethernet network. On the root access point,
this parameter is always enabled.
Disabled
Choose Disabled to use data link tunneling. The access
point forwards data from the wireless network
encapsulated in OWL data frames to the root access point.
The root access point unencapsulates these frames and
dumps them raw on the Ethernet network. Also, the root
access point encapsulates all Ethernet traffic that is sent to
the wireless network. When access points receive this
traffic, they forward it to the wireless network. This process
makes it seem like all wireless traffic is originating on the
root access point’s switch port. You may need to use data
link tunnels to make roaming transparent to network
protocols that are not designed to accommodate
roaming.
Secondary LAN Bridge Priority
Determines when and if the access point can become the
designated bridge in a secondary LAN. To become a designated
bridge, the access point must have at least one radio configured
as a Station node or be the endpoint of an IP tunnel. The access
point that meets either one of these requirements and has the
highest secondary LAN bridge priority will be the designated
bridge.
The secondary LAN bridge priority can be a value from 0 to 7. If
you set the priority to 0, wireless traffic is encapsulated and will
use data link tunneling to the secondary LAN bridge. The
secondary LAN bridge will then forward the data to the primary
LAN.
