+1. Abstract
+
+ This memo defines a portion of the Management Information Base (MIB)
+ for use with network management protocols in the Internet community.
+ In particular, it describes objects used for managing ATM-based
+ interfaces, devices, networks and services.
+
+ This memo replaces RFC 1695 [24]. Changes relative to RFC 1695 are
+ summarized in the MIB module's REVISION clause.
+
+ Textual Conventions used in this MIB are defined in [6] and [19].
+
+2. The SNMP Network Management Framework
+
+ The SNMP Management Framework presently consists of five major
+ components:
+
+ 0 An overall architecture, described in RFC 2271 [1].
+
+ 0 Mechanisms for describing and naming objects and events
+ for the purpose of management. The first version of this
+ Structure of Management Information (SMI) is called SMIv1 and
+ described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC
+ 1215 [4]. The second version, called SMIv2, is described in RFC
+ 1902 [5], RFC 1903 [6] and RFC 1904 [7].
+
+ 0 Message protocols for transferring management information. The
+ first version of the SNMP message protocol is called SNMPv1 and
+ described in STD 15, RFC 1157 [8]. A second version of the SNMP
+ message protocol, which is not an Internet standards track
+ protocol, is called SNMPv2c and described in RFC 1901 [9] and
+ RFC 1906 [10].
+
+
+
+
+
+Tesink Standards Track [Page 2]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+ The third version of the message protocol is called SNMPv3 and
+ described in RFC 1906 [10], RFC 2272 [11] and RFC 2274 [12].
+
+ 0 Protocol operations for accessing management information. The
+ first set of protocol operations and associated PDU formats is
+ described in STD 15, RFC 1157 [8]. A second set of protocol
+ operations and associated PDU formats is described in RFC 1905
+ [13].
+
+ 0 A set of fundamental applications described in RFC 2273 [14] and
+ the view-based access control mechanism described in RFC 2275
+ [15].
+
+ Managed objects are accessed via a virtual information store, termed
+ the Management Information Base or MIB. Objects in the MIB are
+ defined using the mechanisms defined in the SMI.
+
+ This memo specifies a MIB module that is compliant to the SMIv2. A
+ MIB conforming to the SMIv1 can be produced through the appropriate
+ translations. The resulting translated MIB must be semantically
+ equivalent, except where objects or events are omitted because no
+ translation is possible (e.g., use of Counter64). Some machine
+ readable information in SMIv2 will be converted into textual
+ descriptions in SMIv1 during the translation process. However, this
+ loss of machine readable information is not considered to change the
+ semantics of the MIB.
+
+3. ATM Terminology
+
+ Some basic ATM terminologies are described in this section to
+ facilitate defining the ATM managed objects.
+
+3.1. VCL/VPL and VCC/VPC
+
+ There are two distinct types of ATM virtual connections: Virtual
+ Channel Connections (VCCs) and Virtual Path Connection (VPCs). As
+ shown in Figures 1 and 2, ATM virtual connections consist of
+ concatenated series of virtual links which forms a path between two
+ end points, with each concatenation occurring at an ATM switch.
+ Virtual links of VCCs are called Virtual Channel Links (VCLs).
+ Virtual links of VPCs are called Virtual Path Links (VPLs). The VCI
+ and VPI fields in the ATM cell header associate each cell of a VCC
+ with a particular VCL over a given physical link. The VPI field in
+ the ATM cell header associates each cell of a VPC with a particular
+ VPL over a given physical link. Switches route cells between VCLs
+ (or VPLs) via a cross-connect function according to the cells'
+ VCI/VPI (or VPI) values.

+
+
+ A single ATM end-system or switch does not support the whole end-to-
+ end span of a VCC (or VPC). Rather, multiple ATM end-systems and/or
+ switches each support one piece of the VCC (or VPC). That is, each
+ ATM end-system (or ATM switch) at one end of the VCC/VPC supports its
+ end of the VCC/VPC plus the VCL or VPL on its external interface, and
+ each switch through which the VCC/VPC passes supports the pair of
+ VCLs/VPLs on its external interfaces as well as the cross-connection
+ of those VCLs/VPLs. Thus, the end-to-end management of a VCC or VPC
+ is achieved only by appropriate management of its individual pieces
+ in combination.
+
+ Note that for management purposes, an ATM network may be viewed as a
+ large distributed switch by hiding all the network's internal
+ connectivity as being internal to the distributed switch (as shown in
+ Figure 2a). This model may for example be used for Customer Network
+ Management (CNM) purposes.

+ switch
+
+ A VCC has a set of traffic characteristics (i.e., bandwidth
+ parameters, service category parameters, etc.). VCLs inherit their
+ traffic characteristics from the VCC of which they are a part. VCCs
+ are bi-directional by definition. However, the traffic parameters in
+ the two directions of a connection can be symmetric or asymmetric,
+ i.e., the two directions can have the same or different traffic
+ flows. A uni-directional traffic flow across a VCC is achieved by
+ assigning a zero bandwidth in one direction. Note that in addition
+ to the bandwidth required by the user traffic flow, bandwidth is also
+ required for OAM cell flows, even for the zero-bandwidth direction of
+ a uni-directional connection. These same principles apply to VPCs.
+
+3.2. PVC, SVC and Soft PVC
+
+ A Permanent Virtual Connection (PVC) is a provisioned VCC or VPC. A
+ Switched Virtual Connection (SVC) is a switched VCC or VPC that is
+ set up in real-time via call set-up signaling procedures. A PVC (or
+ an SVC) can be a point-to-point, point-to-multipoint, or multipoint-
+ to-multipoint VCC or VPC. A Soft PVC is a connection of which
+ portions are switched, while other portions are permanent (see Figure
+ 3 and [22]).

+
+3.3. Traffic Management Parameters
+
+3.3.1. Traffic Policing and Traffic Shaping Parameters
+
+ In order to allocate resources fairly among different users, some
+ networks police traffic at resource access points. The traffic
+ enforcement or policing taken at a UNI is called Usage Parameter
+ Control (UPC) and is conceptually activated on an incoming VCL or VPL
+ as shown in Figure 4. The use of the traffic enforcer at the ingress
+ of the connection is to make sure that the user traffic does not
+ exceed the negotiated traffic parameters such as the peak cell rate
+ associated with a specific traffic descriptor type.
+
+ ---------- ----------
+ UNI | ATM | NNI | ATM | UNI
+ | | switch | | | switch | |
+ O<---|---->X(UPC) |<----|------>| (UPC)X<-----|--->O
+ | VCL | | | VCL | | VCL |
+ ---------- ----------
+
+
+ Figure 4: An Example of a UPC
+
+ In addition, traffic shaping may be performed on an outgoing VPL or
+ VCL at a given ATM interface. The function of the ATM traffic
+ shaper, conceptually either at the source or an egress point of the
+ connection, is to smooth the outgoing cell traffic inter-arrival
+ time. If policing or shaping is not performed then the policing or
+ shaping algorithm is not activated.
+
+3.3.2. Cell Loss Priority
+
+ To prioritize traffic during resource congestion, ATM cells are
+ assigned one of the two types of Cell Loss Priority (CLP), CLP=0 and
+ CLP=1. ATM cells with CLP=0 have a higher priority in regard to cell
+ loss than ATM cells with CLP=1. Therefore, during resource
+ congestions, CLP=1 cells are dropped before any CLP=0 cell is
+ dropped.
+
+3.3.3. QoS Class
+
+ RFC1695 specified that one of a number of Quality of Service (QoS)
+ classes is assigned to a VCC or VPC by associating the object
+ atmTrafficQoSClass with each VCL or VPL. However, new insights in
+ ATM traffic management have caused this object to be deprecated.
+
+
+
+
+
+
+Tesink Standards Track [Page 6]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+3.3.4. Service Category
+
+ Replacing QoS Class, VPLs and VCLs are qualified in terms of their
+ service category (atmServiceCategory). When properly configured, VCLs
+ (or VPLs) concatenated to form a VCC (or VPC) will all have the same
+ service category class as that of the VCC (or VPC).
+
+3.4. Max Active and Max Current VPI and VCI Bits
+
+ A manager may wish to configure the maximum number of VPI and VCI
+ bits that can be used to identify VPIs and VCIs on a given ATM
+ interface. This value can be less than or equal to the maximum
+ number of bits supported by the interface hardware, and is referred
+ to in the MIB as the Max Active VPI Bits and Max Active VCI Bits.
+
+ However, a manager may not be able to configure the Max Active Bits
+ on both ends of an ATM link. For example, the manager may not be
+ allowed write access to the peer's MIB, or there may be hardware
+ limitations on the peer device. Therefore, the two ATM devices may
+ use ILMI to negotiate "Max Current" VPI and VCI bits, which is the
+ maximum number of bits that both interfaces are willing to support.
+ This is illustrated in Figure 5. The relationship between the
+ different parameters is illustrated in Figure 6. Note that if ILMI
+ negotiation is not supported, then the devices have no choice but to
+ use the configured Max Active bits, and assume that it has been
+ configured to the same value on both ends of the link.

+ (between IF a and IF b, the minimum of the two configured
+ "Max Active VPI Bits" is 6, so both interfaces set their

+ set their "Max Current VPI Bits" to 8.)

+
+4. Overview
+
+ ATM management objects are used to manage ATM interfaces, ATM virtual
+ links, ATM cross-connects, AAL5 entities and AAL5 connections
+ supported by ATM hosts, ATM switches and ATM networks. This section
+ provides an overview and background of how to use this MIB and other
+ potential MIBs for this purpose.
+
+ The purpose of this memo is primarily to manage ATM PVCs. ATM SVCs
+ are also represented by the management information in this MIB.
+ However, full management of SVCs may require additional capabilities
+ which are beyond the scope of this memo.
+
+4.1. Background
+
+ In addition to the MIB module defined in this memo, other MIB modules
+ are necessary to manage ATM interfaces, links and cross-connects.
+ Examples include MIB II for general system and interface management
+ [16][17], the DS3 or SONET MIBs for management of physical
+ interfaces, and, as appropriate, MIB modules for applications that
+ make use of ATM, such as SMDS. These MIB modules are outside the
+ scope of this specification.
+
+ The current specification of this ATM MIB is based on SNMPv2-SMI.
+
+

+
+Tesink Standards Track [Page 8]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+4.2. Structure of the MIB
+
+ The managed ATM objects are arranged into the following tables:
+
+ (1) ATM interface configuration table
+ (2) ATM interface DS3 PLCP and TC sublayer tables
+ (3) ATM traffic parameter table
+ (4) ATM interface virtual link (VPL/VCL) configuration
+ tables
+ (5) ATM VP/VC cross-connect tables
+ (6) AAL5 connection performance statistics table
+
+ Note that, managed objects for activation/deactivation of OAM cell
+ flows and ATM traps notifying virtual connection or virtual link
+ failures are outside the scope of this memo.
+
+4.3. ATM Interface Configuration Table
+
+ This table contains information on ATM cell layer configuration of
+ local ATM interfaces on an ATM device in addition to the information
+ on such interfaces contained in the ifTable.
+
+4.4. ATM Interface DS3 PLCP and TC Layer Tables
+
+ These tables provide performance statistics of the DS3 PLCP and TC
+ sublayer of local ATM interfaces on a managed ATM device. DS3 PLCP
+ and TC sublayer are currently used to carry ATM cells respectively
+ over DS3 and SONET transmission paths.
+
+4.5. ATM Virtual Link and Cross-Connect Tables
+
+ ATM virtual link and cross-connect tables model bi-directional ATM
+ virtual links and ATM cross-connects. The ATM VP/VC link tables are
+ implemented in an ATM host, ATM switch and ATM network. The ATM
+ switch and ATM network also implement the ATM VP/VC cross-connect
+ tables. Both link and cross-connect tables are implemented in a
+ carrier's network for Customer Network Management (CNM) purposes.
+
+ The ATM virtual link tables are used to create, delete or modify ATM
+ virtual links in an ATM host, ATM switch and ATM network. ATM
+ virtual link tables along with the cross-connect tables are used to
+ create, delete or modify ATM cross-connects in an ATM switch or ATM
+ network (e.g., for CNM purposes).
+
+ For a PVC, the cross-connect between two VPLs is represented in the
+ atmVpCrossConnectTable of the ATM-MIB, indexed by the
+ atmVplCrossConnectIdentifier values for the two VPLs, and the cross-
+
+
+
+
+Tesink Standards Track [Page 9]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+ rconnect between two VCLs is represented in the
+ atmVcCrossConnectTable of the ATM-MIB, indexed by the
+ atmVclCrossConnectIdentifier values for the two VCLs.
+
+ For an SVC or Soft PVC the VPL and VCL tables defined in this memo
+ are used. Hoewever, for an SVC or Soft PVC the cross-connect between
+ two VPLs is represented in the atmSvcVpCrossConnectTable of the
+ ATM2-MIB, indexed by the atmVplCrossConnectIdentifier values for the
+ two VPLs, and the cross-connect between two VCLs is represented in
+ the atmSvcVcCrossConnectTable of the ATM2-MIB, indexed by the
+ atmVclCrossConnectIdentifier values for the two VCLs.
+
+ Note: The ATM2-MIB module was being defined in a separate memo at the
+ time of this publication. Please consult the RFC directory for an
+ exact reference.
+
+5. Application of MIB II to ATM
+
+5.1. The System Group
+
+ For the purposes of the sysServices object in the System Group of MIB
+ II [16], ATM is a data link layer protocol. Thus, for ATM switches
+ and ATM networks, sysServices will have the value "2".
+
+5.2. The Interface Group
+
+ The Interfaces Group of MIB II defines generic managed objects for
+ managing interfaces. This memo contains the media-specific
+ extensions to the Interfaces Group for managing ATM interfaces.
+
+ This memo assumes the interpretation of the Interfaces Group to be in
+ accordance with [17] which states that the interfaces table (ifTable)
+ contains information on the managed resource's interfaces and that
+ each sub-layer below the internetwork layer of a network interface is
+ considered an interface. Thus, the ATM cell layer interface is
+ represented as an entry in the ifTable. This entry is concerned with
+ the ATM cell layer as a whole, and not with individual virtual
+ connections which are managed via the ATM-specific managed objects
+ specified in this memo. The inter-relation of entries in the ifTable
+ is defined by Interfaces Stack Group defined in [17].
+
+5.2.1. Support of the ATM Cell Layer by ifTable
+
+ Some specific interpretations of ifTable for the ATM cell layer
+ follow.

+
+
+ Object Use for the generic ATM layer
+ ====== =============================
+
+ ifIndex Each ATM port is represented by an ifEntry.
+
+ ifDescr Description of the ATM interface.
+
+ ifType The value that is allocated for ATM is 37.
+
+ ifSpeed The total bandwidth in bits per second
+ for use by the ATM layer.
+
+ ifPhysAddress The interface's address at the ATM protocol
+ sublayer; the ATM address which would be used as the value
+ of the Called Party Address Information Element (IE) of a
+ signalling message for a connection which either:
+ - would terminate at this interface, or
+ - for which the Called Party Address IE
+ would need to be replaced by the Called Party SubAddress
+ IE before the message was forwarded to any other
+ interface.
+ For an interface on which signalling is not supported,
+ then the interface does not necessarily have an address,
+ but if it does, then ifPhysAddress is the address which
+ would be used as above in the event that signalling were
+ supported. If the interface has multiple such addresses,
+ then ifPhysAddress is its primary address. If the
+ interface has no addresses, then ifPhysAddress is an octet
+ string of zero length. Address encoding is as per [20].
+ Note that addresses assigned for purposes other than those
+ listed above (e.g., an address associated with the service
+ provider side of a public network UNI) may be represented
+ through atmInterfaceSubscrAddress.
+
+ ifAdminStatus See [17].
+
+ ifOperStatus Assumes the value down(2) if the ATM cell
+ layer is down.
+
+ ifLastChange See [17].
+
+ ifInOctets The number of received octets over the
+ interface, i.e., the number of received, assigned cells
+ multiplied by 53.
+
+ ifOutOctets The number of transmitted octets over the interface,
+ i.e., the number of transmitted, assigned cells multiplied
+ by 53.

+ errors.
+
+ ifInUnknownProtos The number of received cells discarded during cell
+ header validation, including cells with unrecognized
+ VPI/VCI values, and cells with invalid cell header
+ patterns. If cells with undefined PTI values are
+ discarded, they are also counted here.
+
+ ifOutErrors See [17].
+
+ ifName Textual name (unique on this system) of the
+ interface or an octet string of zero length.
+
+ ifLinkUpDownTrapEnable Default is disabled (2).

+ ifHCInOctets The 64-bit version of ifInOctets; supported
+ if required by the compliance statements in [17].
+
+ ifHCOutOctets The 64-bit version of ifOutOctets; supported
+ if required by the compliance statements in [17].
+
+ ifAlias The non-volatile 'alias' name for the interface
+ as specified by a network manager.
+
+6. Support of the AAL3/4 Based Interfaces
+
+ For the management of AAL3/4 CPCS layer, see [18].
+
+7. Support of the AAL5 Managed Objects
+
+ Support of AAL5 managed objects in an ATM switch and ATM host are
+ described below.
+
+7.1. Managing AAL5 in a Switch
+
+ Managing AAL5 in a switch involves:
+
+ (1) performance management of an AAL5 entity as
+ an internal resource in a switch
+
+ (2) performance management of AAL5 per virtual connection
+
+
+
+
+
+Tesink Standards Track [Page 12]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+ AAL5 in a switch is modeled as shown in Figure 7 and 8. AAL5 will be
+ managed in a switch for only those virtual connections that carry
+ AAL5 and are terminated at the AAL5 entity in the switch. Note that,
+ the virtual channels within the ATM UNIs carrying AAL5 will be
+ switched by the ATM switching fabric (termed as ATM Entity in the
+ figure) to the virtual channels on a proprietary internal interface
+ associated with the AAL5 process (termed as AAL5 Entity in the
+ figure). Therefore, performance management of the AAL5 resource in
+ the switch will be modeled using the ifTable through an internal
+ (pseudo-ATM) virtual interface and the AAL5 performance management
+ per virtual connection will be supported using an additional AAL5
+ connection table in the ATM MIB. The association between the AAL5
+ virtual link at the proprietary virtual, internal interface and the
+ ATM virtual link at the ATM interface will be derived from the
+ virtual channel cross-connect table and the virtual channel link
+ table in the ATM MIB. Note that for the proprietary virtual interface
+ the traffic transmit and receive conventions in the virtual channel
+ link table are as follows:
+
+ Transmitting traffic: ATM Entity ---> AAL5 Entity
+ Receiving traffic: ATM Entity <--- AAL5 Entity

+7.2. Managing AAL5 in a Host
+
+ Managing AAL5 in a host involves managing the AAL5 sublayer interface
+ as shown in Figure 9 and 10. The AAL5 sublayer is stacked directly
+ over the ATM sublayer. The ifTable is applied to the AAL5 sublayer
+ as defined in Section 10.3.

+7.3. Support of AAL5 by ifTable
+
+ The AAL5 entity in an ATM device (e.g., switch or host) is managed
+ using the ifTable. There are additional counters specified for AAL5
+ than those specified in the ATM B-ICI document [21]. Specific
+ interpretations of ifTable for the AAL5 CPCS layer are as follows.
+
+ Object Use for AAL5 CPCS layer entity
+ ====== ==============================
+
+ ifIndex Each AAL5 entity is represented by an ifEntry.
+
+ ifDescr Description of the AAL5 entity.
+
+ ifType The value that is allocated for AAL5 is 49.
+
+ ifMtu Set to the largest PDU size for the
+ AAL5 CPCS layer that can be processed
+ by the AAL5 entity.

+ [Note: The number of AAL5 PDUs actually
+ transmitted is the number received from a
+ higher-layer for transmission minus any which
+ are counted by ifOutErrors and ifOutDiscards.]

+
+7.5. AAL5 Connection Performance Statistics Table
+
+ An AAL5 connection table is used to provide AAL5 performance
+ information for each AAL5 virtual connection that is terminated at
+ the AAL5 entity contained within an ATM switch or host.

+8. ILMI MIBs and the ATM Managed Objects
+
+ The ILMI MIBs are specified by the ATM Forum as a set of several
+ MIBs, all currently defined in the ILMI Specification [23]. The ILMI
+ protocols and MIBs allow two connected ATM Interface Management
+ Entities (IMEs) to exchange bi-directional parameters, mainly to
+ facilitate auto-configuration between ATM peer entities. The support
+ of the ATM management functions by the ILMI MIBs and those contained
+ in this memo are compared in Table 1. In this table, "yes" in the
+ "ILMI MIBs" column indicates that the management functions are
+ supported by the ILMI MIBs. The parenthesized numbers in the "This
+ memo" column correspond to the sets of tables enumerated in Section
+ 6.2.
+
+ For that subset of management information which the ILMI MIBs and
+ this memo have in common, every effort has been made to retain
+ identical semantics and syntax, even though the MIB objects are
+ identified using different OBJECT IDENTIFIERs.

+ (2) The manager selects an existing row(s) in the

+ (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

+ for that VPL.
+
+ (4) If the VPL terminates a VPC in the ATM host

+
+ One-Shot VPL Establishment
+
+ A VPL may also be established in one step by a

+
+ In contrast to the negotiated VPL establishment
+ which allows for detailed error checking

+
+ Step-wise Procedures to set up a VP Cross-connect
+
+ Once the entries in the atmVplTable are created,
+ the following procedures are used
+ to cross-connect the VPLs together.
+
+ (1) The manager obtains a unique
+ atmVpCrossConnectIndex by reading the
+ atmVpCrossConnectIndexNext object.
+
+ (2) Next, the manager creates a set of one
+ or more rows in the ATM VP Cross Connect
+ Table, one for each cross-connection between
+ two VPLs. Each row is indexed by the ATM
+ interface port numbers and VPI values of the
+ two ends of that cross-connection.
+ This set of rows specifies the topology of the
+ VPC cross-connect and is identified by a single
+ value of atmVpCrossConnectIndex.
+
+ Negotiated VP Cross-Connect Establishment
+
+ (2a) The manager creates a row in this table by
+ setting atmVpCrossConnectRowStatus to
+ createAndWait(5). The agent checks the
+ requested topology and the mutual sanity of
+ the ATM traffic parameters and
+ service categories, i.e., the row creation
+ fails if:
+ - the requested topology is incompatible with
+ associated values of atmVplCastType,
+ - the requested topology is not supported
+ by the agent,
+ - the traffic/service category parameter values
+ associated with the requested row are
+ incompatible with those of already existing
+ rows for this VP cross-connect.
+ [For example, for setting up
+ a point-to-point VP cross-connect, the
+ ATM traffic parameters in the receive direction
+
+
+
+Tesink Standards Track [Page 50]
+
+RFC 2515 ATM Management Objects February 1999
+
+
+ of a VPL at the low end of the cross-connect
+ must equal to the traffic parameters in the
+ transmit direction of the other VPL at the
+ high end of the cross-connect,
+ otherwise, the row creation fails.]
+ The agent also checks for internal errors
+ in building the cross-connect.
+
+ The atmVpCrossConnectIndex values in the
+ corresponding atmVplTable rows are filled
+ in by the agent at this point.
+
+ (2b) The manager promotes the row in the
+ atmVpCrossConnectTable by setting
+ atmVpCrossConnectRowStatus to active(1). If
+ this set is successful, the agent has reserved
+ the resources specified by the ATM traffic
+ parameter and Service category values
+ for each direction of the VP cross-connect
+ in an ATM switch or network.
+
+ (3) The manager sets the
+ atmVpCrossConnectAdminStatus to up(1) in all
+ rows of this VP cross-connect to turn the
+ traffic flow on.
+
+
+ One-Shot VP Cross-Connect Establishment
+
+ A VP cross-connect may also be established in
+ one step by a set-request with all necessary
+ parameter values and atmVpCrossConnectRowStatus
+ set to createAndGo(4).
+
+ In contrast to the negotiated VP cross-connect
+ establishment which allows for detailed error
+ checking (i.e., set errors are explicitly linked
+ to particular resource acquisition failures),
+ the one-shot VP cross-connect establishment
+ performs the setup on one operation but does not
+ have the advantage of step-wise error checking.
+
+ VP Cross-Connect Retirement
+
+ A VP cross-connect identified by a particular

+
+ (1) Setting atmVpCrossConnectRowStatus of all

+
+
+ rows identified by this value of
+ atmVpCrossConnectIndex to destroy(6).
+ The agent may release all
+ associated resources, and the
+ atmVpCrossConnectIndex values in the
+ corresponding atmVplTable row are removed.
+ Note that a situation when only a subset of
+ the associated rows are deleted corresponds
+ to a VP topology change.
+
+ (2) After deletion of the appropriate
+ atmVpCrossConnectEntries, the manager may
+ set atmVplRowStatus to destroy(6) the
+ associated VPLs. The agent releases
+ the resources and removes the associated
+ rows in the atmVplTable.
+
+ VP Cross-connect Reconfiguration
+
+ At the discretion of the agent, a VP
+ cross-connect may be reconfigured by
+ adding and/or deleting leafs to/from
+ the VP topology as per the VP cross-connect
+ establishment/retirement procedures.
+ Reconfiguration of traffic/service category parameter
+ values requires release of the VP cross-connect
+ before those parameter values may by changed

+
+12. Security Considerations
+
+ There are a number of management objects defined in this MIB that
+ have a MAX-ACCESS clause of read-write and/or read-create. Such
+ objects may be considered sensitive or vulnerable in some network
+ environments. The support for SET operations in a non-secure
+ environment without proper protection can have a negative effect on
+ network operations.
+
+ The managed objects in this MIB contain sensitive information since,
+ collectively, they allow tracing and influencing of virtual
+ connections in ATM switches or networks and provide information of
+ their traffic characteristics.
+
+ It is thus important to control even GET access to these objects and
+ possibly to even encrypt the values of these object when sending them
+ over the network via SNMP. Not all versions of SNMP provide features
+ for such a secure environment.
+
+ SNMPv1 by itself is not a secure environment. Even if the network
+ itself is secure (for example by using IPSec), even then, there is no
+ control as to who on the secure network is allowed to access and
+ GET/SET (read/change/create/delete) the objects in this MIB.
+
+ It is recommended that the implementers consider the security
+ features as provided by the SNMPv3 framework. Specifically, the use
+ of the User-based Security Model RFC 2274 [12] and the View-based
+ Access Control Model RFC 2275 [15] is recommended.
+
+ It is then a customer/user responsibility to ensure that the SNMP
+ entity giving access to an instance of this MIB, is properly
+ configured to give access to the objects only to those principals
+ (users) that have legitimate rights to indeed GET or SET
+ (change/create/delete) them.
