Debug
Enables PPPoE connection debugging facilities. The
Debug
option is used by ISP
technical support and ODM/OEM testers to simulate packets going through the
network from the WAN side.
PPP
Unnumbered
Specifies that the calling and answering routers will not request IP addresses.
PPP Unnumbered is a special feature. It enables the ISP to designate a block of
public IP addresses to the customer where it is statically assigned on the LAN
side. PPP Unnumbered is, in essence, like a bridged connection.
LAN
The LAN field is associated with the PPP Unnumbered field and is enabled when
the PPP Unnumbered field is checked. You can specify the LAN group the packets
need to go to when the PPP Unnumbered feature is activated.
Valid Rx
This field is used in conjunction with the On-Demand feature and is enabled only
when the On Demand field is checked.
When the On-Demand feature is enabled and Valid Rx is unchecked, only packets
going from the LAN side to the WAN side keep the link active. After the RG times
out, no packets can be received from the WAN side to the LAN side.
When Valid Rx is checked, the incoming packets can keep the PPPoE WAN
connection active. There is one condition; this incoming packet should belong to a
connection initiated from a LAN-side device.
Host Trigger
This field is used in conjunction with the On-Demand feature and is enabled only
when the On Demand field is checked.
There are three types of packets:
•
LAN packets (type 1): packets routed through the RG from LAN to WAN.
•
Proxied packets (type 2): packets generated by the RG after receiving
packets from the LAN side, such as DNS proxy.
•
Locally generated packets (type 3): Packets generated by the RG, such as
Voice, SNMP, etc.
When the On-Demand feature is enabled and Host Trigger is unchecked, only
flow of type 1 packets keeps the link active, i.e., if the RG has not received type 1
packets for x mount of time (as specified in the Time Out field), the connection
times out.
If Host Trigger is checked, type 2 and type 3 packets can keep the link active as
well. You can configure the packets using the Trigger Traffic page, which is
accessed by clicking the Configure button next to Host Trigger. The following fields
can be used to identify the traffic of type 2 and/or type 3 that will keep the link
alive:
•
Source Port (the character * is used to denote any port)
•
Destination Port (the character * is used to denote any port)
•
Protocol (TCP, UDP, ICMP, or Specify the protocol number)

In the PVC Settings section, enter values as supplied by your ISPI.
PVC Settings:
PVC
Permanent virtual circuit. This is a fixed virtual circuit between two users. It is the
public data network equivalent of a leased line. No call setup or clearing
procedures are needed.
