    Configuring and Verifying Lockout for PPPoE Clients

    To configure and verify encapsulation type lockout for a PPPoE client:

    1. Configure the underlying physical interface.

      For example, the following commands configure a static ATM 1483 subinterface and corresponding ATM PVC. For more information about the atm pvc command, see Creating a PVC on an ATM 1483 Subinterface

      host1(config)#interface atm 3/0 host1(config-if)#interface atm 3/0.101 host1(config-subif)#atm pvc 10 10 20 aal5snap
    2. Create a static PPPoE major interface.
      host1(config-subif)#encapsulation pppoe
    3. Configure the PPPoE major interface to detect and accept dynamic PPPoE subinterfaces. Use the lockout-time keyword to configure a nondefault lockout time range for the PPPoE clients associated with the dynamic PPPoE subinterface column.

      For example, the following command configures a lockout time in the range 5–60 seconds for the PPPoE clients associated with the dynamic PPPoE subinterface column on the PPPoE major interface.

      host1(config-subif)#pppoe auto-configure lockout-time 5 60
    4. Assign a profile to the PPPoE major interface.
      host1(config-subif)#pppoe profile pppoeLockoutProfile

      The default encapsulation type, any, applies to any autoconfigured encapsulation that does not have a specific profile assignment.

      For information about creating and using profiles, see Dynamic Interface Configuration Using a Profile and Configuring Profile Characteristics.

    5. (Optional) Verify the lockout configuration by using either of the following commands.
      • To display summary information about the lockout configuration, use the show pppoe interface command. (The following example shows only the portion of the command display relevant to the PPPoE lockout configuration.)
        host1#show pppoe interface atm 3/0.101
        PPPoE interface ATM 3/0.101 is operStatusUp (dynamic)
        . . .
        Lockout Configuration (seconds): Min 5, Max 60
         Total clients in active lockouts: 0
         Total clients in lockout grace period: 0
      • To display detailed information about the current lockout condition for each PPPoE client associated with a specific source MAC address, 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

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