MobileLAN access 21XX System Manual
designated bridge
A 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 Intermec 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.
flooding
A frame is flooded when the destination location is unknown. The destination location
of a multicast frame is never known. Unicast and multicast flooding parameters
determine how a flooded frame is forwarded.
hello period
A time increment (usually 1, 2, or 3 seconds) that determines how often the access
point sends out a type of multicast packet so that it can dynamically discover and test
connections to other devices in the network. Once this information is learned, the
access point and routers can exchange routing information.
home IP subnet
Also called the primary LAN. The IP subnet that contains the root access point. If you
are using IP tunneling and wireless end devices need roam between IP subnets, each
end device needs to have an IP address from the home IP subnet.
