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 cre-
     ated.  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 interface 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.

SEE ALSO
     en(4), pvc(4), ifconfig(8), pvctxctl(8)

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