Usage Scenario
A PPPoE client and server negotiate the service name during PPPoE negotiation. PPPoE negotiation is successful only if the client and server have the same service name configured. A PPPoE server can have different service names configured to carry different types of services.
A VT can have a maximum of eight service names configured. To configure a service name matching mode, run the pppoe-server service-name-type command.
