Server Trusted
State Select whether this port is a trusted port (
Truste d
) or an untrusted port (
Untruste d
).
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
Adva nc e d Applic a tio n > PPPo E
> Inte rm e dia te Ag e nt > Po rt > VLAN
screen) has the highest priority.
Remote-id Enter a string of up to 63 ASCII characters that the Switch adds into the Agent Remote ID sub-
option for PPPoE discovery packets received on this port. Spaces are allowed.
If you do not specify a string here or in the
Re m o te - id
field for a VLAN on a port, the Switch
automatically uses the PPPoE client’s MAC address.
The Remote ID you configure for a specific VLAN on a port (in the
Adva nc e d Applic a tio n >
PPPo E > Inte rm e dia te Ag e nt > Po rt > VLAN
screen) has the highest priority.
