Monitoring the PPPoE Interface

Purpose

Display information about the parameters on a PPPoE interface or subinterface as well as the operational and administrative status of all configured PPPoE interfaces.

Note: If you do not specify an interface and subinterface, the router displays the PPPoE interface and status parameters for all configured interfaces. If you specify an interface with no subinterface, the router displays the PPPoE interface and status parameters for that interface. If you specify an interface and subinterface, the router displays detailed parameters available for that subinterface.

Action

To display information about the PPPoE interface over an ATM interface: 

host1#show pppoe interface atm 1/0.1 
PPPoE interface ATM 1/0.1 is operStatusUp (dynamic)
    PPPoE interface ATM 1/0.1 has max sessions = 4000
    PPPoE interface ATM 1/0.1 has acName of 111111111111111
    PPPoE interface ATM 1/0.1 will not send ac info in PADS packet 

    PPPoE interface ATM 1/0.1 is in duplicate-protection
    PPPoE interface ATM 1/0.1 will capture remote circuit ID 

    PPPoE interface ATM 1/0.1 has 1 active connections,
        out of 1 configured subinterfaces
