| Description | Each entry in this table represents a Soft
Permanent Virtual Path Connection (Soft PVPC)
originating at a switch interface.
A Soft PVPC is a VPC that is:
- provisioned at the originating (source)
interface of the connection
- established by signalling procedures
across a network to a destination interface.
A row in the atmVplTable must be created,
defining a VPL on the source interface, prior to
creating an atmSoftPVpcEntry row. The row in the
atmVplTable must be active prior to activating the
atmSoftPVpcEntry row.
The contents of this table reflect only the
characteristics unique to a Soft PVPC. The traffic
parameters are defined in the VPL row for the source
interface, as specified in the ATOMMIB (RFC1695) and
the forthcoming addition, the Supplemental ATOMMIB.
Note that the atmSigDescrParamTable contains some
objects such as the AAL parameters, Broadband high
layer information, and Broadband low layer information
elements which are used to carry end-to-end information.
For this reason, these objects are not relevant to Soft
PVPCs.
When a row is made active, an attempt is made
to set up a switched connection to an interface at
the destination switch. No objects (other than
atmSoftPVpcRowStatus) can be set while the row is
active.
At the destination, the VPL may be defined (but
not cross-connected) prior to arrival of the Setup
request.
The combination of ifIndex, atmVplVpi specified
in the index clause of this entry serves to
identify the VPL on the source interface. The
atmSoftPVpcLeafReference object aids in distinguishing
between leaves of a point-to-multipoint Soft PVPC. |
