    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

    Total Invalid PAD packets

    Total number of invalid control packets received on the interface

    Insufficient Resources

    Number of requests denied because of an inadequate number of sessions; check the number of active clients

    Lockout Configuration (seconds)

    Encapsulation type lockout settings for the PPPoE client associated with the dynamic PPPoE subinterface column. For more information about these fields, see Encapsulation Type Lockout for PPPoE Clients Overview. Possible values include:

    Summary Statistics

    Summary of the PPPoE statistics. Possible value:

    • Total PPPoE interfaces—Number of configured PPPoE interfaces included in summary

    Administrative Status

    Administrative status of the PPPoE interfaces. Possible values:

    • Up—Number of interfaces not affected by manual administrative intervention
    • Down—Number of interfaces that cannot flow because of manual administrative intervention

    Operational Status

    Operational status of the PPPoE interfaces. Possible values:

    • Up—Number of interfaces that are operational
    • Down—Number of interfaces that are not operational
    • LowerLayerDown—Number of interfaces that are not operational because an underlying interface is down
