Glossary
264
spanning tree
A form of network organization in which each device on the network has
only one path to the root. The access points automatically configure into a
self-organized network that provides efficient, loop-free forwarding of
frames through the network.
splitter
The MobileLAN splitter converts 48V input power to 5V or 3.3V output
power. If you want to use power over Ethernet, you plug the access point
into the splitter and then you plug the splitter into a MobileLAN power
bridge.
The WA22, WA21, and 2100 do not use a splitter.
SWAP (Secure Wireless Authentication Protocol)
This protocol creates secure wireless hops if you enable secure IAPP. It
forces access points to authenticate each other using an EAP-MD5
challenge.
TLS (Transport Layer Security)
An EAP authentication type that not only requires a certificate on the
authentication server, but also one on the end device. There is both server
and client side authentication before the end device can communicate
with the network.
TTLS (Tunneled Transport Layer Security)
An EAP authentication type that only requires a certificate on the
authentication server. End devices have a user name and password that
proves that they are authorized to communicate with the network.
triangular routing
The routing logic used for a mobile IP end device that has roamed to a
foreign network. Frames destined for a mobile end device are always sent
to the home subnet of the end device. If the end device has roamed to
another subnet, the frame must be forwarded to the remote subnet where
the end device currently resides.
unicast address
A unique Ethernet address assigned to a single device on the network.
WAP (Wireless Access Point)
Also called a repeater. This access point does not have any connections on
its Ethernet port. It forwards data between the access point and the
secondary LAN.
