Explanation
Enter a unique name for this access point. The name can be from 1 to
16 characters. The default is the access point serial number.
If you have an OpenAir master radio, only the first 11 characters are
used.
Enter the LAN ID. All access points must have the same LAN ID to
participate in the same spanning tree. The LAN ID can be from 0 to
254.
If you are using OpenAir radios, all OpenAir devices in a network must
have the same LAN ID to be able to communicate. Also, if you assign a
LAN ID greater than 15, the access point uses a LAN ID that is the
remainder after dividing the LAN ID by 16. For example, if you set the
LAN ID to 21 or 37, the access point uses 5.
Determines if this access point is a candidate to become the root of the
spanning tree. The access point with the highest root priority becomes
the root whenever it is powered on and active.
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.
Note: If your network contains 6710 and 21XX access points,
configure a 21XX as the root.
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.
Determines how wireless frames are converted to Ethernet frames and
vice versa. Choose Enabled if you want frames to be forwarded directly
to the Ethernet network. On the root access point, this parameter is
always enabled.
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.
