PVCSIF(8)                 BSD System Manager's Manual                PVCSIF(8)

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 proto-
     cols requiring multicast, such as RSVP and IPv6, over a PVC WAN connec-
     tion.

     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.
