Password
Your password for the PPPoE access provided by your DSL service
provider or your ISP. This field is alpha-numeric and the maximum length is
128 characters. The character type restrictions do not apply for CLI-based
configuration.
Idle Timeout
Specifies that PPPoE connection should disconnect if the link has no
activity detected for n seconds. This field is used in conjunction with the
On-Demand feature and is enabled only when the On Demand field is
checked. To ensure that the link is always active, enter a 0 in this field.
You can also enter a value larger than 10 (secs).
Keep Alive
When the On Demand option is not enabled, this value specifies the time
to wait without being connected to your provider before terminating the
connection. To ensure that the link is always active, enter a 0 in this field.
You can also enter any positive integer value in this field.
Authentication
Three authentication options are available:
z
Auto
z
Challenge handshake authentication protocol (CHAP)
z
Password authentication protocol (PAP)
Microsoft CHAP v2 is also supported in the Auto and CHAP options.
However, MS CHAP v1 is not supported.
MTU
Maximum transmit unit the DSL connection can transmit. It is a negotiated
value that packets of no more than n bytes can be sent to the service
provider. The PPPoE interface default MTU is 1492 (max) and PPPoA
default MTU is 1500 (max). The minimum MTU value is 64.
On Demand
Enables On Demand mode. The connection disconnects if no activity is
detected after the specified idle timeout value. When checked, this field
enables the following fields:
z
Idle Timeout
z
Host Trigger
z
Valid Rx
Default Gateway
If checked, this WAN connection acts as the default gateway to the
Internet.
Enforce MTU
This feature is enabled by default. It forces all TCP traffic to conform with
PPP MTU by changing TCP maximum segment size to PPP MTU. If it is
disabled, you may have issues accessing some Internet sites.
Debug
Enables PPPoE connection debugging facilities. This option is used by ISP
technical support and ODM/OEM testers to simulate packets going through
the network from the WAN side.
PPP
Unnumbered
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.
Field
Definition/Description
Sharing
The following options are available:
z
Disable: Disables connection sharing.
z
Enable: Enables connection sharing.
z
VLAN: The VLAN ID and Priority Bits fields are activated when VLAN is
selected, which enable you to create VLAN.
VLAN ID
VLAN Identification. Multiple connections over the same PVC are supported,
which requires the WAN network to have VLAN support and for the DSLAMS and
Routers on the ISP to handle VLAN Tags.
Extended support is also available, which allows multiple connections to be
placed over the single PVC without VLAN support (VLAN Tag of 0 is this special
case). In this mode of operation, a received packet is flooded on all the
connections that reside over it.
