PPPoE

When a VC is configured for PPPoE, the router will auto-detect the Authentication code (PAP or CHAP).
The NAPT and DHCP server functions will be enabled automatically.
STEP 1: Click WAN Setup on the Basic menu bar and enter the following parameters to set up PPPoE.
VPI
VCI
LLC Encapsulation:
VC Multiplexing:
Enable NAPT
User Name/Password
Mode
Idle Timeout
Enable DHCP server
Keepalive
Interval(sec):
24
Enter a value for the vitual path identifier
Enter a value for the virtual channel identifier
With LLC encapsulation, a link control header is added to the
Ethernet packet that identifies the protocol type (Ethernet). This
allows multiple protocols to be transmitted over the ATM Virtual
Circuit.
With VC Multiplexing, no link control header is needed as the ATM
Virtual Circuit is assumed to be carrying a single protocol.
Selecting Enabling NAPT will enable Network Port Address
Translation on the WAN interface.
These two fields are used for remote subscriber to log on for
Internet access.
Direct and Auto. If the mode is set to Auto, the PPPoE negotiation
automatically starts when the system identifies any traffic required
to be transferred on the link. When DIRECT is selected the PPPoE
negotiation is started manually.
The Idle Time field defines the period of idle time after which the
PPPoE link will be terminated. It is functional in the auto mode.
The default setting is 5 minutes. In Direct mode, this function is not
used and the field displays zero.
Check the item to enable the DHCP server or uncheck it to disable
it.
Keep-alive is a networking operation that periodically (default-
every 10 seconds) checks the availability of a PPPoE/PPPoA
connection between the CO and CPE. If the keep-alive message is
not acknowledged, the connection will be interrupted.
