    Creating a Bulk-Configured VC Range on a Static ATM AAL5 Interface

    You can use the atm bulk-config command to create a bulk-configured VC range on a static ATM AAL5 interface for use by a dynamic ATM 1483 subinterface.

    Note: For information about the maximum number of ATM 1483 bulk configurations supported per chassis, see JunosE Release Notes, Appendix A, System Maximums.

    Each VC range consists of one or more nonoverlapping VC subranges. A VC subrange is a group of VCs that resides within the VPI and VCI ranges you specify. You can configure multiple VC ranges on an ATM AAL5 interface.

    Note: For information about the maximum number of VCs (sum of the VPI/VCI addresses within all VC subranges) that you can configure with the atm bulk-config command per line module and per chassis, see JunosE Release Notes, Appendix A, System Maximums.

    Do not use any reserved VCI values when configuring VCs with the atm bulk-config command. For information about reserved VCIs, see Unresolved xref in Unresolved xref.

    When you create a bulk-configured VC range, you must specify the following:

    • A name of up to 80 alphanumeric characters; this is also referred to as the bulk configuration name
    • The starting and ending VPI values (inclusive) for each VC subrange
    • The starting and ending VCI values (inclusive) for each VC subrange

    You can create a placeholder VC range by issuing the atm bulk-config command without specifying any subranges. You can assign a profile to this placeholder and add subranges to it later.

    You can add and remove individual VC subranges. You cannot remove a VC subrange if any dynamic ATM 1483 subinterfaces currently exist for any circuit within the subrange. You can use the atm bulk-config shutdown command to remove dynamic ATM 1483 interfaces created within a subrange. Removal of a subrange automatically results in the removal of all overriding profile assignments on that subrange. You can create a bulk-configured VC subrange that includes the VPI and VCI addresses belonging to an existing ATM PVC on a static ATM interface.

    You cannot create a bulk-configured VC range on an ATM interface on which you have configured CAC. Conversely, you cannot configure CAC on an ATM interface on which you have created a bulk-configured VC range. For information about configuring CAC, see Unresolved xref in Unresolved xref.

    To create a bulk-configured VC range on a static ATM AAL5 interface for use by a dynamic ATM 1483 subinterface:

    • Configure a VC range named myBulkConfig with a single VC subrange containing VPIs 0–2 and VCIs 101–1100; this command configures a total of 3000 VCs
      host1(config-if)#atm bulk-config myBulkConfig vc-range 0 2 101 1100
    • Configure a VC range named myMultiBulkConfig with two VC subranges containing VPIs 0–1 and VCIs 101–600 (first subrange) and VPIs 3–5 and VCIs 201–3200 (second subrange); this command configures a total of 10,000 VCs
      host1(config-if)#atm bulk-config myMultiBulkConfig vc-range 0 1 101 600 vc-range 3 5 201 3200

    Use the no version to remove the specified VC range from the ATM AAL5 interface, to remove the specified subranges from the specified VC range, or to remove all subranges from the specified VC range. The no version also removes any overriding profile assignments for ATM PVCs within the deleted VC range or VC subrange.
