4.1.3 PPPoE Encapsulation
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an
IETF (Internet Engineering Task Force) draft standard specifying how a host personal
computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to
achieve access to high-speed data networks.
For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for instance, Radius).
One of the benefits of PPPoE is the ability to let end users access one of multiple network
services, a function known as dynamic service selection. This enables the service provider to
easily create and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.
For more information on PPPoE, see
4.2 Configuring Ethernet
Click ETHERNET in the navigation panel to display the ETHERNET screen. Use the
ETHERNET Ethernet screen to configure the Prestige’s Ethernet interfaces with Internet
account information from your ISP. Your ISP may have already configured some of the fields
for you.
You can manage the Prestige through the Ethernet IP address, but you may not always know
the Prestige’s IP address (especially if the IP address is dynamic). Use the Mgnt Port screen
(see
) to configure a static IP address that you use to access the Prestige
for management.
