To verify PPPoE configuration perform the following tasks:
Verify the PPPoE configuration for an Ethernet interface.
From the J-Web interface, select Configuration>View and Edit>View Configuration Text. Alternatively, from configuration mode in the CLI, enter the show interfaces command from the top level.
Verify that the output shows the intended configuration of PPPoE.
Verify the PPPoE configuration for an ATM-over-ADSL or ATM-over-SHDSL interface.
From the J-Web interface, select Configuration>View and Edit>View Configuration Text. Alternatively, from configuration mode in the CLI, enter the show interfaces command from the top level.
