Profile Interface Configuration
PPP over Ethernet (PPPoE) is a data-link protocol for dialup connections. PPPoE allows the access point to use a
broadband modem (DSL, cable modem, etc.) for access to high-speed data and broadband networks. Most DSL
providers are currently supporting (or deploying) the PPPoE protocol. PPPoE uses standard encryption, authentication,
and compression methods as specified by the PPPoE protocol. PPPoE enables WiNG supported controllers and access
points to establish a point-to-point connection to an ISP over existing Ethernet interface.
To provide this point-to-point connection, each PPPoE session learns the Ethernet address of a remote PPPoE client,
and establishes a session. PPPoE uses both a discover and session phase to identify a client and establish a
point-to-point connection. By using such a connection, a Wireless WAN failover is available to maintain seamless
network access if the access point's Wired WAN were to fail.
When PPPoE client operation is enabled, it discovers an available server and establishes a PPPoE link for traffic slow.
When a wired WAN connection failure is detected, traffic flows through the WWAN interface in fail-over mode (if
the WWAN network is configured and available). When the PPPoE link becomes accessible again, traffic is redirected
back through the access point's wired WAN link.
When the access point initiates a PPPoE session, it first performs a discovery to identify the Ethernet MAC address
of the PPPoE client and establish a PPPoE session ID. In discovery, the PPPoE client discovers a server to host the
PPPoE connection.

NOTE: Access points with PPPoE enabled continue to support VPN, NAT, PBR and 3G
failover over the PPPoE interface. Multiple PPPoE sessions are supported using a single
user account user account if RADIUS is configured to allow simultaneous access.
NOTE: PPPoE is supported on AP-7131, AP-7161 and AP-6532 models and is not available
on AP-6521 and AP-6511 model access points.
