dual-homed connection - A redundant, resilient connection between a DWL-8220AP access point
and one or more DWS-1008 switches. The connection can consist of two direct physical links from both
AP ports to one or two DWS-1008 switches, one or more distributed links through an intermediate Layer
2 or Layer 3 network, or a combination of one direct physical link and one or more distributed links. The
AP uses one link for booting, configuration, and data transfer and uses the other link(s) as backups
in case the active link fails. If the AP has two direct physical links to one or more switches, the Power
over Ethernet (PoE) load is shared across both links. If the active data link fails, the other link provides
uninterrupted power to the AP access point.
After changing its active link, the access point reboots and loads new configuration information to
ensure proper configuration and security. See also bias.
EAP - Extensible Authentication Protocol. A general point-to-point protocol that supports multiple
authentication mechanisms. Defined in RFC 2284, EAP has been adopted by IEEE 802.1X in an
encapsulated form for carrying authentication messages in a standard message exchange between
a user (client) and an authenticator. The encapsulated EAP, also known as EAP over LAN (EAPoL)
and EAP over Wireless (EAPoW), enables the authenticator's server to authenticate the client with an
authentication protocol agreed upon by both parties. See also EAP type.
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 over Wireless - See EAPoL.
EAPoW - See EAPoL.
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 D-Link Mobility 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 Mobility System Software (MSS) command-line interface (CLI)
commands required for configuration and troubleshooting. Enabled access requires a separate enable
password. Compare restricted access.
