Assigning an Overriding Profile to an ATM PVC

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:
   • Base profile for the bulk-configured VC range on the static ATM AAL5 interface. The VC range consists of one or more VC subranges.
   • Overriding profile for an ATM PVC within a bulk-configured VC subrange

   For information about configuring profiles, see Configuring a Dynamic Interface from a Profile in Configuring Dynamic Interfaces.

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.

   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.

   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.

   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.

   host1(config-if)#auto-configure atm1483

7. (Optional) Use the show atm bulk-config command to verify the overriding profile configuration.

   For more information about using this command, see show atm bulk-config.
