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.
For example, the following command configures a circuit for autodetection of the ATM 1483 encapsulation and all higher layers.
- host1(config-subif)#atm pvc 100 0 100 aal5autoconfig
0 0 0
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.
