Glossary
Encryption Data passing between the SU-A-EZ and clients can use
encryption to protect from interception and evesdropping.
Extended Service Set
(ESS)
Extended Service Set: More than one wireless cell can be
configured with the same Service Set Identifier to allow mobile
users can roam between different cells with the Extended
Service Set.
Extensible Authentication
Protocol (EAP)
An authentication protocol used to authenticate network
clients. EAP is combined with IEEE 802.1X port authentication
and a RADIUS authentication server to provide “mutual
authentication” between a client, the access point, and the a
RADIUS server
File Transfer Protocol

Local Area Network (LAN) Local Area Network: A group of interconnected computer and
support devices.
MAC Media Access Control: The lower of the two sub-layers of the
data link layer defined by the IEEE. The MAC sub-layer
handles access to shared media, such as whether token
passing or contention will be used.
MAC Address
Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network and to create and update routing tables and data
structures. MAC addresses are 6bytes long and are controlled
by the IEEE.
Network Time Protocol
(NTP)
NTP provides the mechanisms to synchronize time across the
network. The time servers operate in a
hierarchical-master-slave configuration in order to synchronize
local clocks within the subnet and to national time standards
via wire or radio.
