Chapter 6 Edit Interface/Connection
Connection: ADSL
Click the drop-down menu and choose to create a new dynamic DNS method.
To clear an associated dynamic DNS method from the interface, choose None
from the drop-down menu.
Connection: ADSL
This window enables you to specify or edit properties of a PPPoE link supported
by an ADSL connection.
Encapsulation
Choose the type of encapsulation that will be used for this link.
• PPPoE specifies Point-to-Point Protocol over Ethernet encapsulation.
• PPPoA specifies Point-to-Point Protocol over ATM encapsulation.
• RFC 1483 Routing (AAL5 SNAP) specifies that each PVC can carry multiple
protocols.
• RFC 1483 Routing (AAL5 MUX) specifies that each PVC can carry only one
type of protocol.
If you are editing a connection, the encapsulation is shown, but not editable. If you
need to change the encapsulation type, delete the connection and re-create it using
the encapsulation type you need.
For more information on these encapsulation types, click Encapsulation
Autodetect.
Virtual Path Identifier
The virtual path identifier (VPI) is used in ATM switching and routing to identify
the path used for a number of connections. Enter the VPI value given to you by
your service provider.
If you are editing an existing connection, this field is disabled. If you need to
change this value, delete the connection and re-create it using the value you need.
