Allied Telesis AT-WA7501, AT-WA7500 Designated bridge, Dhcp Dynamic Host Configuration Protocol

AT-WA7500 and AT-WA7501 Installation and User’s Guide

To enable data link tunneling, disable Ethernet bridging.

designated bridge

Also called a secondary LAN bridge. An access point that is assigned the role of bridging frames destined for or received from a secondary LAN. A designated 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.

directional antenna

An antenna (often called a yagi) that transmits and receives RF signals more in one direction than others. This radiation pattern is similar to the light that a flashlight produces. These antennas have a narrower beam width, which limits coverage on the sides of the antennas. Directional antennas have much higher gain than omni antennas and work best for covering large narrow areas or on point-to-point bridges.

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.

EAP (Extensible Authentication Protocol)

Used in 802.1x-enabled networks. A standard mechanism for support of different authentication methods. EAP authentication types provide devices with secure connections to the network as well as protect credentials and data privacy. See also “TLS” and “TTLS.”
