    Configuring Overriding Profile Assignments

    Configuring overriding profile assignments includes the following tasks:

    Assigning an Overriding Profile to an ATM PVC Within a Bulk-Configured VC Subrange

    You can assign an overriding profile to a single ATM PVC within a bulk-configured VC subrange. Typically, the overriding profile includes debugging attributes to help you identify and troubleshoot problems with the ATM 1483 dynamic subinterface column created on the specified PVC.

    To assign an overriding profile to an ATM PVC within a bulk-configured VC subrange:

    1. Configure both of the following:

      For information about configuring profiles, see Dynamic Interface Configuration Using a Profile.

    2. Create a bulk-configured range of VCs on a static ATM AAL5 interface. The following commands create a bulk-configured VC range named myBulkConfig that consists of two VC subranges. The first subrange encompasses VPIs 0–4 and VCIs 21–1000. The second subrange encompasses VPIs 5–7 and VCIs 21–2000. For more information, see Creating a Bulk-Configured VC Range on a Static ATM AAL5 Interface.
      host1(config)#interface atm 4/0 host1(config-if)#atm bulk-config myBulkConfig vc-range 0 4 21 1000
      vc-range 5 7 21 2000
    3. Assign the previously configured base profile (atm1483BaseProfile) to the bulk-configured VC range. For more information, see Assigning the Base Profile Configured for a Dynamic ATM 1483 Subinterface to the VC Range Configured on a Static ATM AAL5 Interface.
      host1(config-if)#profile atm1483 bulk-config-name myBulkConfig atm1483BaseProfile
    4. Assign the previously configured overriding profile to a single ATM PVC within the bulk-configured VC subrange. The following command assigns the overriding profile myDebugProfile to the PVC with VPI 0 and VCI 101. This PVC exists within the first VC subrange (VPIs 0–4 and VCIs 21–1000) configured in Step 2. For more information, see Assigning an Overriding Profile to a Single ATM PVC that Exists Within a Bulk-Configured VC Subrange
      host1(config-if)#profile atm1483 bulk-config-name myBulkConfig pvc 0 101 myDebugProfile

      The router now uses the information in the overriding profile instead of the information in the base profile to create subsequent ATM 1483 dynamic subinterface columns over this PVC.

    5. (Optional) You can assign the same overriding profile to a different ATM PVC within the same VC subrange or within a different VC subrange. For example, the following command assigns the overriding profile myDebugProfile to the PVC with VPI 6 and VCI 901. This PVC exists within the second VC subrange (VPIs 5–7 and VCIs 21–2000) configured in Step 2.
      host1(config-if)#profile atm1483 bulk-config-name myBulkConfig pvc 6 901 myDebugProfile

      Note: You can reverse the order of Step 3 and Step 4 with identical results. That is, you can assign the overriding profile to the ATM PVC and then assign the base profile to the entire VC range. In either case, you must first create the bulk-configured VC range with the atm bulk-config command.

    6. Configure the ATM AAL5 interface to enable all bulk configurations and to support autodetection of the ATM 1483 dynamic encapsulation type. For more information, see Configuring the Static ATM AAL5 Interface to Support Autodetection of an ATM 1483 Dynamic Encapsulation Type.
      host1(config-if)#auto-configure atm1483
    7. (Optional) Use the show atm bulk-config command to verify the overriding profile configuration. For more information, see Monitoring Bulk-Configured VC Ranges on an ATM AAL5 Interface.

    Removing an Overriding Profile Assignment from an ATM PVC

    After you troubleshoot the ATM 1483 dynamic subinterface column created on the specified PVC, make sure that you remove the overriding profile assignment to restore the original base profile assignment. This action ensures that subsequent ATM 1483 dynamic subinterface columns are created using the same attributes defined in the base profile.

    To remove an overriding profile assignment from an ATM PVC within a bulk-configured VC range:

    1. Remove the overriding profile assignment from the specified ATM PVC. For more information, see Assigning the Base Profile Configured for a Dynamic ATM 1483 Subinterface to the VC Range Configured on a Static ATM AAL5 Interface.
      host1(config-if)#no profile atm1483 bulk-config-name myBulkConfig pvc 0 101
    2. Select the dynamic ATM 1483 subinterface on which the ATM 1483 dynamic subinterface column resides. For more information, see Unresolved xref in Unresolved xref.
      host1(config)#interface atm 4/0.101
    3. Use the shutdown command to disable the dynamic ATM 1483 subinterface. The shutdown command deletes the ATM 1483 dynamic subinterface column and removes the dynamic ATM 1483 subinterface. For more information, see Disabling a Dynamic ATM 1483 Interface.
      host1(config-subif)#shutdown
    4. Send traffic over the specified PVC (VPI 0 and VCI 101) on the ATM AAL5 interface. This action re-creates the ATM 1483 dynamic subinterface column with the original base profile association.

      The router now uses the information in the base profile instead of the information in the overriding profile to create subsequent ATM 1483 dynamic subinterface columns for the specified PVC.

    5. (Optional) Use the show atm bulk-config command to verify the removal of the overriding profile assignment. For more information, see Monitoring Bulk-Configured VC Ranges on an ATM AAL5 Interface.

    Removing an Overriding Profile Assignment from a VC Range or VC Subrange

    When you issue the no atm bulk-config command to remove an entire VC range (and all VC subranges within that VC range), the router also removes any overriding profile assignments configured for PVCs within those VC subranges.

    To remove the bulk-configured VC range named myBulkConfig and any overriding profile assignments for PVCs within the VC subranges belonging to myBulkConfig:

    • Issue the no atm bulk-config command in Interface Configuration mode without VC subranges.
      host1(config-if)#no atm bulk-config myBulkConfig

    When you issue the no atm bulk-config command to remove a particular VC subrange in a bulk-configured VC range, the router also removes any overriding profile assignments for PVCs within that VC subrange. However, overriding profile assignments for PVCs within other VC subranges in the VC range remain intact.

    To remove one VC subrange (VPIs 0–4 and VCIs 21–1000) and only those overriding profile assignments associated with this subrange:

    • Issue the no atm bulk-config command in Interface Configuration mode with VC subrange.
      host1(config-if)#no atm bulk-config myBulkConfig vc-range 0 4 21 1000
