NAME
     pvcsif -- configure ATM PVC sub interfaces

SYNOPSIS
     pvcsif interface [-s]
     pvcsif -a

DESCRIPTION
     pvcsif creates a sub interface for an ATM PVC.  A sub interface pvc(4) is dynamically created.  The created interface is bound to interface
     but at this point no VC is assigned.  To assign a VC, pvctxctl(8) should be used later.

     A PVC sub interface is intended to use an ATM PVC as an alternative serial connection, and to be allocated per PVC basis.	A PVC sub inter-
     face looks as a point-to-point interface and is multicast capable, as opposed to the NBMA (NonBroadcast Multiple Access) model that requires
     a MARS server.  A point-to-point interface is useful to run MBone or protocols requiring multicast, such as RSVP and IPv6, over a PVC WAN
     connection.

     Note that a sub interface is not a full-fledged interface but just an indirect reference to the real interface.

     The options are as follows:

     -s 	 For use with a shell, it prints the created interface name.

     -a 	 Lists the existing sub interfaces.

BUGS
     Currently, there is no way to remove a sub interface.
