Description: Indicates whether well-known VCs should be automatically or manually created for the interface.

In automatic(1) mode, well-known VCs will be created with default VPI/VCI values upon startup or upon entry to the automatic mode. While in this mode, well-known VCs will not be allowed to be deleted or modified by user commands. This is the default mode at startup for equipment which supports automatic well-known VC creation.

In manual(2) mode, well-known VCs won't be automatically created. Instead, the user will be allowed to delete and create PVCs with the reserved encapsulation types aalQsAal, aal5Ilmi, and aal5Pnni as applicable. And these PVCs will be allowed to have VCI values in the range <5-16383>, instead of <32-16383>.

The manualDeleteUponEntry(3) action causes any existing VCs with reserved encapsulation types (aalQsAal, aal5Ilmi or aal5Pnni) to be deleted for this interface as it enters the manual state.
