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.
