1. A VT interface must be bound to an interface so that the PPPoE server can be implemented.
The PPPoE server can be configured on a physical Ethernet interface, a PON interface, a VLANIF interface, or a virtual Ethernet interface.
2. The dialer interface must be bound to an interface so that the PPPoE client can be implemented.
The PPPoE client can be configured on a physical Ethernet interface, a PON interface, or a virtual Ethernet interface.
The physical Ethernet interfaces refer to WAN-side Ethernet interfaces. LAN-side Ethernet interfaces do not support PPPoE.
Link aggregation has no restriction on service card specifications. For details about restrictions on Eth-Trunk member interfaces, see corresponding configuration and command reference manuals. You are not advised to add interfaces of different rates to the same Eth-Trunk interface, because this configuration may waste resources and cause packet loss. (The X16SFC/X40SFC does not support link aggregation with other types of cards).
