MobileLAN access 21XX System Manual
multicast address
A form of broadcast address through which copies of the frame are delivered to a subset
of all possible destinations that have a common multicast address.
NAT (Network Address Translation)
A mechanism for reducing the need for different IP addresses. NAT allows an
organization with IP addresses that are not unique to connect to the network by
translating those addresses into routable address space.
non-bridging secondary LAN
A secondary LAN that does not have a designated bridge. A non-bridging secondary
LAN is used to interconnect access points without using wireless hops.
outbound frames
Frames moving away from the primary LAN.
peer-to-peer network
A type of LAN whose workstations are capable of being both clients and servers.
point-to-point bridge
A bridge connects wireless devices to a wired network and allows connection of
networks or subnetworks with similar architectures. Two access points can be used to
provide a point-to-point bridge between two buildings so that wired and wireless
devices in each building can communicate with devices in the other building.
primary bridging
Ethernet bridging on a root port. A access point uses primary bridging to bridge frames
to and from the Ethernet network on its root port. Note that primary bridging is not the
same as bridging to the primary LAN.
primary LAN
Also called the home IP subnet. The Ethernet LAN that is attached to the root access
point. The primary LAN is typically the LAN on which the servers are located. Primary
and secondary LANs are both distribution LANs.
QFSK (Quad Frequency Shift Key)
A broadcasting method that shortens the range but doubles the throughput as compared
to the BFSK method. In access points using a 2.4 GHz OpenAir radio, the radio can
automatically switch between QFSK and BFSK as needed if the transmit mode is set to
AUTO.
