DESCRIPTION
"This is the MIB Module for ATM and AAL5-related
objects for managing ATM interfaces, ATM virtual
links, ATM cross-connects, AAL5 entities, and
and AAL5 connections."
REVISION "9810191200Z"
DESCRIPTION
"The initial revision of this module was published
as RFC 1695. Key revisions include:
o Textual Conventions and OBJECT IDENTITIES have
been moved to a separate MIB module.
o Applicability of objects to PVCs, SVCs and Soft
PVCs has been clarified.
o DEFVAL clauses have been added.
o The relationship of ifIndex values with different
layers and sublayers related to ATM has been
clarified.
o atmTrafficQosClass has been deprecated
and replaced with atmServiceCategory.
o atmInterfaceCurrentMaxVpiBits and
atmInterfaceCurrentMaxVciBits have been added with
a description on their relationship with other
objects.
o atmInterfaceAddressType and atmInterfaceAdminAddress
have been deprecated and replaced by
atmInterfaceSubscrAddress.
o atmInterfaceTCAlarmState has been clarified.
o atmTrafficDescrParamIndexNext has been introduced
in order to provide a manager a free
atmTrafficDescrParamIndex value.
o The atmTrafficFrameDiscard capability has been added.
o A connection topology type (atmVpl/VclCastType) and
a call control type (atmVpl/VclConnKind) have been
added.
o aal2 has been added to atmVccAalType."

MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"An entry in the VPL table. This entry is
used to model a bi-directional VPL.
To create a VPL at an ATM interface,
either of the following procedures are used:
Negotiated VPL establishment
(1) The management application creates
a VPL entry in the atmVplTable
by setting atmVplRowStatus to createAndWait(5).
This may fail for the following reasons:
- The selected VPI value is unavailable,
- The selected VPI value is in use.
Otherwise, the agent creates a row and
reserves the VPI value on that port.
(2) The manager selects an existing row(s) in the
atmTrafficDescrParamTable,
thereby, selecting a set of self-consistent
ATM traffic parameters and the service category
for receive and transmit directions of the VPL.
(2a) If no suitable row(s) in the
atmTrafficDescrParamTable exists,
the manager must create a new row(s)
in that table.
(2b) The manager characterizes the VPL's traffic
parameters through setting the
atmVplReceiveTrafficDescrIndex and the
atmVplTransmitTrafficDescrIndex values
in the VPL table, which point to the rows
containing desired ATM traffic parameter values
in the atmTrafficDescrParamTable. The agent
will check the availability of resources and
may refuse the request.
If the transmit and receive service categories
are inconsistent, the agent should refuse the
request.
(3) The manager activates the VPL by setting the
the atmVplRowStatus to active(1).
If this set is successful, the agent has
reserved the resources to satisfy the requested
traffic parameter values and the service category
for that VPL.
(4) If the VPL terminates a VPC in the ATM host
or switch, the manager turns on the
atmVplAdminStatus to up(1) to turn the VPL
traffic flow on. Otherwise, the
atmVpCrossConnectTable must be used
to cross-connect the VPL to another VPL(s)
in an ATM switch or network.
One-Shot VPL Establishment
A VPL may also be established in one step by a
set-request with all necessary VPL parameter
values and atmVplRowStatus set to createAndGo(4).
In contrast to the negotiated VPL establishment
which allows for detailed error checking
(i.e., set errors are explicitly linked to
particular resource acquisition failures),
the one-shot VPL establishment
performs the setup on one operation but
does not have the advantage of step-wise
error checking.
VPL Retirement
A VPL is released by setting atmVplRowStatus to
destroy(6), and the agent may release all
associated resources."
