With the atm pvc command and keywords, you configure multiple PVC attributes on a single command line. In addition, configuration attributes available only for control (ILMI and signaling) PVCs or only for data PVCs are not mutually exclusive.
By contrast, ATM VC Configuration mode provides commands to configure each parameter individually, and makes a clearer distinction between configuration of control PVCs and configuration of data PVCs.
You can configure all of the parameters currently supported by the atm pvc command from within ATM VC Configuration mode. In addition, you can create a PVC with the atm pvc command and modify or delete the same PVC by using ATM VC Configuration mode. Conversely, you can modify (with certain restrictions) or delete a PVC created in ATM VC Configuration mode by using the atm pvc command.
In most cases, you can use either an ATM VC Configuration mode command or the atm pvc command to configure ATM PVC parameters. However, to configure F5 OAM alarm surveillance parameters (by using the oam ais-rdi command) or VC integrity parameters (by using the oam retry command), you must use only ATM VC Configuration mode. There are no equivalent atm pvc commands to configure these parameters.
You can, however, continue to use the atm pvc command to enable VC integrity and modify the loopback frequency of an ATM data PVC.

Note: If you have existing configuration scripts that use the atm pvc command, we recommend that you continue to use the atm pvc command to configure all ATM PVC parameters except those that require you to use the oam ais-rdi command or oam retry command in ATM VC Configuration mode. |
