data link tunneling
An access point encapsulates an Ethernet frame in a data frame and
forwards the frame to the next access point on the path to the final
destination. Data link tunneling is used to make mobility transparent to
the underlying network or to isolate the radio traffic from terminals on
an Ethernet segment. Data link tunneling occurs automatically when
Ethernet bridging is disabled on the root access point. Ethernet bridging
is automatically disabled on a secondary LAN if there is no designated
bridge for the secondary LAN. An access point that has Ethernet
bridging disabled forwards a frame inbound on its Ethernet port using
data link tunneling. The root access point or a designated bridge for a
secondary LAN uses data link tunneling to forward frames outbound to
access points on the same Ethernet segment.
designated bridge
An access point that is assigned the role of bridging frames destined for
or received from a secondary LAN. A designated bridge, or secondary
LAN 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.
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.
