Use this row to make the setting the same for all ports. Use this row first and then make
adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Server Trusted
Select whether this port is a trusted port (Trusted) or an untrusted port (Untrusted).
State
Trusted ports are uplink ports connected to PPPoE servers.
•
If a PADO (PPPoE Active Discovery Offer), PADS (PPPoE Active Discovery Session-
confirmation), or PADT (PPPoE Active Discovery Terminate) packet is sent from a PPPoE
server and received on a trusted port, the Switch forwards it to all other ports.
•
If a PADI or PADR packet is sent from a PPPoE client but received on a trusted port, the
Switch forwards it to other trusted port(s).
Untrusted ports are downlink ports connected to subscribers.
•
If a PADI, PADR, or PADT packet is sent from a PPPoE client and received on an
untrusted port, the Switch adds a vendor-specific tag to the packet and then forwards it
to the trusted port(s).
•
The Switch discards PADO and PADS packets which are sent from a PPPoE server but
received on an untrusted port.
Circuit-id
Enter a string of up to 63 ASCII characters that the Switch adds into the Agent Circuit ID
sub-option for PPPoE discovery packets received on this port. Spaces are allowed.
The Circuit ID you configure for a specific VLAN on a port (in the Advanced Application >
PPPoE > Intermediate Agent > Port > VLAN screen) has the highest priority.
