PMP 450i and PTP 450i Configuration and User
Task 2: Configuring IP and Ethernet interfaces
Point-to-Point Protocol over Ethernet (PPPoE) is a protocol that encapsulates PPP frames
inside Ethernet frames (at Ethernet speeds). Benefits to the network operator may include
• Access control
• Service monitoring
• Generation of statistics about activities of the customer
• Re-use of infrastructure and operational practices by operators who already use PPP for
other networks
PPPoE options are configurable for the SM only, and the AP indicates whether or not
PPPoE is enabled for a specific subscriber.
When PPPoE is enabled, once the RF session comes up between the SM and the AP, the SM
will immediately attempt to connect to the PPPoE Server. You can monitor the status of this
by viewing the PPPoE Session Log in the Logs section (Administrator only). Every time the
RF session comes up, the SM will check the status of the link and if it is down, the SM will
attempt to redial the link if necessary depending on the Timer Type. Also, on the
Configuration page, the user may ‘Connect’ or ‘Disconnect’ the session manually. This can
be used to override the session to force a manual disconnect and/or reconnect if there is a
problem with the session.
In order to enable PPPoE, NAT MUST be enabled on the SM and Translation Bridging
MUST be disabled on the AP. These items is strictly enforced for you when you are trying
to enable PPPoE. A message will indicate any prerequisites not being met. Also, the NAT
Public IP DHCP client cannot be enabled, because the NAT Public IP is received through
the IPCP process of the PPPoE discovery stages.
The pre-requisites are:
• NAT MUST be enabled on the SM
o NAT DHCP Client is disabled automatically. The NAT public IP is
received from the PPPoE Server.
o NAT Public Network Interface Configuration will not be used and
must be left to defaults. Also NAT Public IP DHCP is disabled if it is
enabled.
• Translation Bridging MUST be DISABLED on the AP
o This will only be determined if the SM is in session since the SM
won’t know the AP configuration otherwise. If the SM is not in
session, PPPoE can be enabled but if the SM goes into session to a
Translation Bridge-enabled AP, then PPPoE will not be enabled.
The following PPPoE configuration parameters are available:
Table 19 SM PPPoE attributes
Attribute Meaning
Access
Concentrator
An optional entry to set a specific access concentrator to
connect to for the PPPoE session. If this is blank, the SM will
accept the first access concentrator which matches the
service name (if specified). This is limited to 32 characters.
