11 PPP over Ethernet
PPP over Ethernet (PPPoE) is a means of establishing a PPP connection over the top of an Ethernet
connection. The implementation provided is compliant with RFC 2516, “A Method for Transmitting
PPP Over Ethernet”. A typical application would be to allow non-PPPoE enabled devices to access
Internet services where the connection to the Internet is provided by an ADSL bridge device.
Using the Web Page(s)
There is no dedicated web page for con
fi
guring the unit to use PPPoE; rather there are a number
of parameters that appear on other web pages that must be used in conjunction with each other to
establish a PPPoE connection over the appropriate Ethernet interface.
In particular, the following con
fi
guration pages and parameters are important.
On the appropriate
Confi gure

PPP
pages, you should con
fi
gure the following parameters on the
following pages:
Standard Page
As a minimum requirement the
Username
and
Password
parameters should be initialised. If
necessary, you may set the
AODI Enabled
parameter to “Yes” to con
fi
gure the unit so that it will
attempt to renegotiate the PPP link should it go down for any reason.
Advanced Page
The advanced PPP options on this page should be initialised as required by your ISP. The

ne the physical Ethernet interface over which the PPPoE
session will operate. In most cases this is ETH 0. The fact that you have selected “Ethernet” as the
physical interface for operation with PPP automatically enables PPPoE mode.
In addition:
Desired Local MRU and Desired Remote MRU should be set to 1492.
Request Local ACFC and Request Remote ACFC should be set to No.
Request Local PFC and Request Remote PFC should be set to No.
Using Text Commands
There are no speci

c PPPoE commands available to the user via the text command interface. The
appropriate
ppp
commands should be used to set the required options.
