Chapter 28 PPPoE Table 86 Advanced Application > PPPoE Intermediate Agent > Port (continued) LABEL Server Trusted State DESCRIPTION Select whether this port is a trusted port (Trusted) or an untrusted port (Untrusted). Trusted ports are 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 connected to subscribers. Circuit-id • 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. 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. Remote-id The Circuit ID you configure for a specific VLAN on a port has the highest priority. 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-id field for a VLAN on a port, the Switch automatically uses the PPPoE client's MAC address. Apply Cancel The Remote ID you configure for a specific VLAN on a port has the highest priority. 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 nonvolatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. MES-3528 User's Guide 251
