    Clearing the Lockout Condition for a PPPoE Client

    You can use the pppoe clear lockout interface command to clear the lockout condition for an individual PPPoE client associated with a dynamic PPPoE subinterface column on a static PPPoE major interface. To identify the PPPoE client, you must specify its source MAC address.

    For information about the working of the dynamic encapsulation type lockout feature for PPPoE sessions that contain the IWF-Session DSL Forum VSA (26-254) in PADR packets, see Encapsulation Type Lockout Based on DSL Forum VSAs for IWF PPPoE Sessions.

    Note: Issuing the pppoe clear lockout interface command resets the current lockout condition for the specified PPPoE client, but does not disable dynamic encapsulation type lockout for that PPPoE client.

    To clear the current lockout condition for a PPPoE client:

    1. Display the source MAC address assigned to the PPPoE client by issuing one of the following show commands:
      • To display the source MAC address when there is no available PPPoE session in progress, use the show pppoe interface lockout-time command.

        This command displays multiple entries for the same MAC address if multiple IWF sessions contain the same MAC address. In the following example, more than one entry for the same PPPoE client MAC address, 0090.1a42.527c, is displayed under the Client Address column head. This method of display occurs because the MAC address in the Client Address field denotes the MAC address of the DSLAM device at which multiplexing functions are performed and not the address of the originating PPPoE client (access loop) for PPPoE sessions that contain the IWF-Session DSL Forum VSA (26-154).

        host1#show pppoe interface atm 12/1/1.1.1 lockout-time
        PPPoE interface atm 12/1/1.1
        Lockout Configuration (seconds): Min 90, Max 120
         Total clients in active lockout: 1
         Total clients in lockout grace period: 0
        Client Address Current Elapsed Next
        -------------- ------- ------- ----
        0090.1a42.527c     120      30  120
        0090.1a42.527c       0       0   90
      • To display the source MAC address when a subscriber is connected to the router through an available PPPoE session, use either the show pppoe interface lockout-time command or the show pppoe subinterface full command. (The following example shows only the portion of the command display relevant to the source MAC address.)
        host1#show pppoe subinterface full
        ...
            PPPoE subinterface ATM 3/0.101 has source MAC address 0090.1a10.165e
        ...
        

      For a description of the fields in the command display, see Monitoring Detailed Information About the Current Encapsulation Type Lockout Condition for PPPoE Clients and Monitoring the Source MAC Address of a PPPoE Client.

    2. Clear the current lockout condition for the PPPoE client associated with the specified source MAC address on the static PPPoE major interface.
      host1#pppoe clear lockout interface atm 3/0.101 0090.1a10.165e

      If the specified PPPoE client is undergoing active lockout or is in a lockout grace period, issuing the pppoe clear lockout interface command causes the router to reset the current lockout condition and start the next lockout interval at the minimum configured lockout time.

      The lockout grace period occurs when the time between lockout events is greater than either 15 minutes or the maximum lockout time. When a PPPoE client is in a lockout grace period, the router resets the number of consecutive lockout events to 1. (For more information, see Guidelines for Configuring Encapsulation Type Lockout for PPPoE Sessions.)
