NAME
pvcsif —
configure ATM PVC sub
interfaces
SYNOPSIS
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 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.

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