activity. The MIB for the access point is available from the Allied Telesyn
web site at www.alliedtelesyn.com.
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. The
access point can act as a DHCP/NAT server.
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.
omni antenna
An antenna that transmits and receives RF signals in all directions equally
on a horizontal plane. This radiation pattern is similar to a doughnut with
the antenna being in the center of the doughnut hole. These antennas
provide the widest coverage and are most commonly used inside
buildings.
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-multipoint bridge
See also wireless bridge. A bridge that connects two wired networks with
similar architectures. Two access points can be used to provide a point-to-
multipoint bridge between two buildings so that wired and wireless devices
in each building can communicate with devices in the other building. A
point-to-multipoint bridge has two radios, which allows wireless end
devices to communicate with it.
