Creating a PVC on an ATM 1483 Subinterface

You use the atm pvc command to define the underlying circuit supporting an ATM 1483 subinterface. When you define a circuit with this command by using the aal5autoconfig option, it causes the ATM 1483 encapsulation (LLC/SNAP encapsulation or VC multiplexed) to be autodetected. Alternatively, if you use the aal5snap or aal5mux ip option, the ATM 1483 encapsulation becomes fixed, but higher layers can be dynamic.

To configure a circuit for autodetection of the ATM 1483 encapsulation and all higher layers:

• Issue the atm pvc command with the aal5autoconfig option in Subinterface Configuration mode.
  host1(config-subif)#atm pvc 100 0 100 aal5autoconfig 0 0 0

  Use the no version to remove the specified PVC.

You can also include the atm pvc command in a base profile assigned to a dynamic ATM 1483 interface to apply encapsulation and traffic-shaping parameters to a bulk-configured range of PVCs. For information, see Configuring Dynamic Interfaces Using Bulk Configuration.
