To enable data link tunneling, disable Ethernet bridging.
designated bridge
Also called a secondary LAN bridge. An access point that is assigned the
role of bridging frames destined for or received from a secondary LAN. A
designated bridge connects a secondary LAN with the primary LAN. In the
access point, the secondary LAN bridge priority parameter determines if
the access point is a candidate to become the designated bridge.
DHCP (Dynamic Host Configuration Protocol)
An Internet standard stack protocol that allows dynamic distribution of IP
address and other configuration information to IP hosts on a network.
Implementation of the DHCP client in Allied Telesyn network devices
simplifies installation because the devices automatically receive IP
addresses from a DHCP server on the network.
directional antenna
An antenna (often called a yagi) that transmits and receives RF signals
more in one direction than others. This radiation pattern is similar to the
light that a flashlight produces. These antennas have a narrower beam
width, which limits coverage on the sides of the antennas. Directional
antennas have much higher gain than omni antennas and work best for
covering large narrow areas or on point-to-point bridges.
distribution LAN
Any Ethernet LAN attached to access points that are bridging between the
Ethernet LAN and the radio network. At any given time, only one access
point in a distribution LAN provides access to the Ethernet LAN for a given
node in the domain.
DIX
A standardized Ethernet frame format developed by Digital Equipment
Corporation, Intel Corporation, and Xerox. Another frame format is 802.3.
EAP (Extensible Authentication Protocol)
Used in 802.1x-enabled networks. A standard mechanism for support of
different authentication methods. EAP authentication types provide
devices with secure connections to the network as well as protect
credentials and data privacy. See also “TLS” and “TTLS.”
