EAPoL
EAP over LAN. An encapsulated form of the Extensible Authentication Protocol (EAP), defined in
the IEEE 802.1X standard, that allows EAP messages to be carried directly by a LAN media access control
(MAC) service between a wireless client (or supplicant) and an authenticator. EAPoL is also known as EAP
over Wireless (EAPoW). See also EAP.

EAP-TLS
Extensible Authentication Protocol with Transport Layer Security. An EAP subprotocol for
802.1X authentication. EAP-TLS supports mutual authentication and uses digital certificates to fulfill the
mutual challenge. When a user (client) requests access, the authentication server responds with a server
certificate. The client replies with its own certificate and also validates the server certificate. From the
certificate values, the EAP-TLS algorithm can derive session encryption keys. After validating the client
certification, the authentication server sends the session encryption keys for a particular session to the client.
Compare PEAP.
EAP type
A specific Extensible Authentication Protocol (EAP) authentication mechanism. Both the
wireless client (or supplicant) and the authenticator must support the same EAP type for successful
authentication to occur. EAP types supported in a Nortel WLAN 2300 System wireless LAN (WLAN) include
EAP-MD5, EAP-TLS, PEAP-TLS, PEAP-MS-CHAP, and Tunneled Transport Layer Security (TTLS). See
also MD5; MS-CHAP-V2; PEAP; TLS; TTLS.
EAP with Transport Layer Security
See EAP-TLS.
enabled access
Permission to use all WLAN 2300 System Software (WSS Software) command-line
interface (CLI) commands required for configuration and troubleshooting. Enabled access requires a separate
enable password. Compare restricted access.
encryption
Any procedure used in cryptography to translate data into a form that can be read by only its
intended receiver. An encrypted signal must be decrypted to be read. See also cryptography.
ESS
Extended service set. A logical connection of multiple basic service sets (BSSs) connected to the same
network. Roaming within an ESS is guaranteed by the Nortel WLAN 2300 System.
Ethernet II
The original Ethernet specification produced by Digital, Intel, and Xerox (DIX) that served as
the basis of the IEEE 802.3 standard.
ETSI
European Telecommunications Standards Institute. A nonprofit organization that establishes
telecommunications and radio standards for Europe.
