29.3.1 PPPoE IA Per-Port
Use this screen to specify whether individual ports are trusted or untrusted ports and have the OLT add
extra information to PPPoE discovery packets from PPPoE clients on a per-port basis.
You can also add GPON Option s (dynamic information) of an ONT into the Agent Circuit and/or Remote
ID sub-option for PPPoE discovery packets received on a port. The order of the selected GPON Option s
are determined by the format selected from the drop-down list in the GPON Option field.
The OLT will get the GPON Option s (dynamic information) of an ONT from traffic on a port.
Note: The OLT will drop all PPPoE packets if you enable the PPPoE Intermediate Agent on the
OLT and there are no trusted ports.
The following table introduces the differences among the listed screens.
circuit-id Use this section to configure the Circuit ID field in the PADI and PADR packets.
The Circuit ID you configure for a specific port or for a specific VLAN on a port has priority over
this.
The Circuit ID you configure for a specific port (in the Advanced Application > PPPoE >
Intermediate Agent > Port screen) or for a specific VLAN on a port (in the Advanced Application
> PPPoE > Intermediate Agent > Port > VLAN screen) has priority over this. That means, if you also
want to configure PPPoE IA Per-Port or Per-Port Per-VLAN setting, leave the fields here empty
and configure circuit-id and remote-id in the Per-Port or Per-Port Per-VLAN screen.
Active Select this option to have the OLT add the user-defined identifier string and variables (specified
in the
option field) to PADI or PADR packets from PPPoE clients.
If you leave this option unselected and do not configure any Circuit ID string (using CLI
commands) on the OLT, the OLT will use the string specified in the
access-node-identifier field.
Identifier-
string
Specify a string that the OLT adds in the Agent Circuit ID sub-option. You can enter up to 53
ASCII characters. Spaces are allowed.
option Select the variables that you want the OLT to generate and add in the Agent Circuit ID sub-
option. The variable options include
sp , sv , pv and spv which indicate combinations of slot-port,
slot-VLAN, port-VLAN and slot-port-VLAN respectively. The OLT enters a zero into the PADI and
PADR packets for the slot value.
delimiter Select a delimiter to separate the identifier-string, slot ID, port number and/or VLAN ID from each
other. You can use a pound key (
# ), semi-colon ( ; ), period ( . ), comma ( , ), forward slash ( / ) or
space.
Apply Click Apply to save your changes to the OLT’s run-time memory. The OLT loses these changes if
it is turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to reset the fields to your previous configuration.
