说明
pppoe-discovery sends PPPoE Active Discovery Initiation (PADI) packets on a network interface to find available PPPoE access concentrators. It reports the names and services offered by any responding concentrators without actually establishing a connection. This diagnostic tool is useful for verifying that a DSL modem or network is properly configured and that the ISP's access concentrator is reachable before attempting a full PPPoE connection.
