As needed, such parameters as PPP authentication may also be necessarily 
configured on a Dialer interface. For detailed introduction to the configuration of 
a Dialer interface, refer to related contents in Part XIII “Dial-up”.

PPPoE session can be configured on a physical Ethernet interface or a virtual 
Ethernet (VE) interface created on an ADSL interface. When a router is to be linked 
to the Internet through an ADSL interface, it is necessary to configure PPPoE 
session on the virtual Ethernet interface; when a router is to be linked to an ADSL 
Modem and then the Internet via an Ethernet interface, it is necessary to configure 
the PPPoE session on the Ethernet interface.

Please configure a virtual Ethernet interface in the system view and configure 
PPPoEoA mapping in the ADSL view.

Perform the following configuration in Ethernet interface view or virtual Ethernet 
interface view.

3Com series routers support two kinds of PPPoE connection mode: always-on 
mode and packet triggering mode.

■

Always-on mode: When the physical line is UP, the router will quickly initiate 
PPPoE call to create a PPPoE session. The PPPoE session will always exist unless 
the user deletes it via the 

command.

■

Packet triggering mode: When the physical line is UP, the router will not 
immediately initiate PPPoE call. Only when there is data transmission 
requirement will the router initiate PPPoE call to create a PPPoE session. If the 
free time of a PPPoE link exceeds the value set by user, the router will 
automatically terminate the PPPoE session.
