	Chapter 31 PPPoE
Table 105 Advanced Application > PPPoE > Intermediate Agent > Port (continued)
LABEL	DESCRIPTION
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.
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 Remote-idfield 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 Advanced Application >
	PPPoE > Intermediate Agent > Port > VLAN screen) has the highest priority.
Apply	Click Apply to save your changes to the Switch’s run-time memory. The Switch 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 begin configuring this screen afresh.
