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.
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 Brocade Mobility 1220 Access Point, Brocade Mobility 1220 Access Point,
Brocade Mobility 1240 Access Point, Brocade Mobility 7131 Access Point models and is not
available on Brocade Mobility 6511 Access Point.
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.
To create a PPPoE point-to-point configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Interface menu and select PPPoE.
