Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing ATM-based interfaces, devices, networks and services. This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions. [Temporary Note: Upon progression of this specification as a Proposed Standard, an SNMPv2 and an SNMPv1 version of this MIB module will be made available to ease migration.] This memo does not specify a standard for the Internet community. 3. Change Log This section tracks changes made to the revisions of the Internet Drafts of this document. It will be deleted when the document is published as an RFC. The following changes were made for the version of the document dated February 4, 1994. These changes were made as a result of the comments provided by the AToM MIB Working Group on the 12/22/93 AToM MIB draft. - ATM address type has been added to the ATM interface configuratoin group. - The type of AAL that will be terminated by the virtual connection and the AAL5 related configuration parameters have been added to the VC link group. The following changes were made for the version of the document dated December 22, 1993. These changes were made as a result of the comments provided by the AToM MIB Working Group on the 11/29/93 AToM MIB draft. - Minor modifications to the mapping of the AAL5 Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 2] Internet Draft ATM Management Objects February 4, 1994 sublayer to the Interface Group have been made. - Modifications have been made to align the ATM MIB with the ILMI MIB. - The ATM traffic parameters have been taken out of the VP and VC link tables and are included in a separate table. Texts describing the step-wise setting up of virtual links and cross-connects and the errors which can occur at each step have been added. The following changes were made for the version of the document dated November 29, 1993. These changes were made as a result of the AToM MIB Working Group's meeting in Houston IETF meeting. - A minor modification to the mapping of the ATM layer to the Interface Group has been made. - The VP and VC connection tables have been deleted and new VP and VC cross-connect tables and VP and VC link tables are added for setting up and managing ATM cross-connect and virtual link configurations in ATM networks, switches, routers, and hosts. Appropriate editorial changes are made to reflect this. Texts describing stepwise procedures to set-up ATM virtual links and cross-connects have been added. - The scope of this document is broadened to model AAL5 entity which is an internal resource in an ATM switch. Appropriate editorial changes are made to reflect this. A new approach has been adopted to model the AAL5 entity in an ATM switch using the Interface Group through a proprietary, internal virtual interface. In an ATM host or router, the AAL5 entity is modeled using the Interface Group by directly stacking AAL5 sublayer over ATM sublayer. In addition, a new VC link table specific to AAL5 is added in the ATM MIB for performance monitoring of the AAL5 connections that are terminated at an ATM switch. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 3] Internet Draft ATM Management Objects February 4, 1994 - To be consistent with the ATM Forum UNI specification, the name of the ATM traffic enforcement type has been changed to ATM traffic descriptor type and the policing and shaping traffic parameters have been changed respectively to receive and transmit traffic parameters. - Minor editorial changes. The following changes were made for the version of the document dated October 19, 1993. - Representation of the ATM layer in the Interface Group has been modified as follows: The ATM layer objects are now represented using the fixedLengthGroup in the ifTable. The objects supported are ifIndex, ifDescr, ifType, ifSpeed, ifPhyAddress, ifAdminStatus, ifOperStatus, ifLastChange, ifInOctets, ifInErrors, ifInUnknownProtos, ifSpecific, ifName, ifLinkUpDownTrapEnable, ifHighSpeed, ifHCInOctets, and ifHCOutOctets. The ifPacketGroup does not apply to ATM layer. - The performance parameter group per virtual link has been removed. - The object atmInterfaceSpecific has been deleted from the atmInterfaceConfTable. - There was an error in the atmInterfaceTrafficEnforcementTypes which was corrected. - AAL3/4 and AAL5 are now represented as separate entries in the ifTable. The value of the ifType for AAL3/4 Common Part Convergence Sublayer (CPCS) is the ifType of the SMDS Interface Protocol (SIP). The AAL3/4 CPCS layer objects are represented using the SIP MIB, RFC 1304. - The value of the ifType for AAL5 is 49. The representation of AAL5 using ifTable and in the ATM MIB is currently under study and will be included in the future. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 4] Internet Draft ATM Management Objects February 4, 1994 - The SONET Transmission Convergence (TC) sublayer is renamed as TC sublayer. This is because TC sublayer can be used for carrying ATM directly over SONET as well as directly over DS3 or DS1 physical layers. The following changes were made for the version of the document dated August 9, 1993. - This MIB module is made compliant with SNMPv2 SMI. - This MIB module incorporates the changes agreed upon at the AToM MIB WG meeting in Amsterdam. - The objects atmInterfacePortIdentifier, atmInterfaceTransmissionType and atmInterfaceMediaType have been deleted from the atmInterfaceConfTable. The object atmInterfaceIlmiVpiVci has been clarified. - Entries in the ifTable have been updated for ATM interface, and AAL level interfaces. - Representations of the AAL level interfaces in the Interface Group have been modified as follows: The AAL level is now represented per ATM interface and not per virtual connection. Therefore, the AAL pointer group is deleted. AAL3/4 and AAL5 CPCS layers are now combined and represented as a single entry in the Interface Group. AAl1 SAR layer is also now represented in the Interface Group. - Formal conformance statements have beed added. 4. The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework consists of four major components. They are: RFC 1442 which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 5] Internet Draft ATM Management Objects February 4, 1994 RFC 1213 defines MIB-II, the core set of managed objects for the Internet suite of protocols. RFC 1445 which defines the administrative and other architectural aspects of the framework. RFC 1448 which defines the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 6] Internet Draft ATM Management Objects February 4, 1994 5. Objects Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) [3] defined in the SMI. In particular, each object has a name, a syntax, and an encoding. The name is an OBJECT IDENTIFIER, an administratively assigned name, which specifies an object type. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to also refer to the object type. The syntax of an object type defines the abstract data structure corresponding to that object type. The ASN.1 language is used for this purpose. However, the SMI RFC 1442 purposely restricts the ASN.1 constructs which may be used. These restrictions are explicitly made for simplicity. The encoding of an object type is simply how that object type is represented using the object type's syntax. Implicitly tied to the notion of an object type's syntax and encoding is how the object type is represented when being transmitted on the network. The SMI specifies the use of the basic encoding rules of ASN.1 [4], subject to the additional requirements imposed by the SNMPv2. 5.1. Format of Definitions Section 12 contains the specification of all object types contained in this MIB module. The object types are defined using the conventions defined in the SNMPv2 SMI. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 7] Internet Draft ATM Management Objects February 4, 1994 6. ATM Terminology Some basic ATM terminologies are described in this section to facilitate defining the ATM managed objects. 6.1. 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. <-----------------------VCC-----------------------------> ------------ ----------- |ATM | |ATM | |X-Connect | |X-Connect | VCL1 |Point | VCL2 |Point | VCL3 O---------|----X-----|-------|--------|----X-----|-------O | | | | ------------ ------------ ATM Switch ATM Switch Figure 1: Virtual Channel Links and Virtual Channel Connection Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 8] Internet Draft ATM Management Objects February 4, 1994 <-----------------------VPC-----------------------------> ------------ ----------- |ATM | |ATM | |X-Connect | |X-Connect | VPL1 |Point | VPL2 |Point | VPL3 O---------|----X-----|-------|--------|----X-----|-------O | | | | ------------ ------------ ATM Switch ATM Switch Figure 2: Virtual Path Links and Virtual Path Connection 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 at one end of the VCC/VPC supports its end of the VCC/VPPC plus the VCLs or VPLs on its external interfaces, and each switch through which the VCC/VPC passes, supports the multiple VCLs/VPLs on that switch's external interfaces and the cross-connection of those VCLs/VPLs through that switch. 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. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 9] Internet Draft ATM Management Objects February 4, 1994 <-----------------------VCC-----------------------------> ---------------------------------------- | | | ---------- ---------- | | | ATM | | ATM | | VCL1 | | Switch | | Switch | | VCL3 O---------|-|--------|------/---------|--------|-|-------O | | | | | | | ---------- ---------- | | | | ATM Network | ---------------------------------------- Figure 2a: ATM Network modeled as a Large distributed switch A VCC has a set of traffic characteristics (i.e., bandwidth parameters, QoS Class 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 even when there is no bandwidth assigned to the opposite direction of a uni-directional user traffic flow, to allow OAM cell flow, the bandwidth is set to some nominal value. These same principles apply to VPCs. 6.2. PVC and SVC 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. 6.3. Traffic Management Parameters Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 10] Internet Draft ATM Management Objects February 4, 1994 6.3.1. 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 activated on an incoming VCL or VPL as shown in Figure 3. 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 3: 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 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. ATM Forum has specified seven traffic descriptor types including one for the best effort traffic [12]. 6.3.2. 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. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 11] Internet Draft ATM Management Objects February 4, 1994 6.3.3. QoS Class A VCC or VPC is associated with one of a number of Quality of Service (QoS) classes. The following service classes have been specified: Service Class A: Constant bit rate video and Circuit emulation Service Class B: Variable bit rate video/audio Service Class C: Connection-oriented data Service Class D: Connectionless data Four QoS classes numbered 1, 2, 3, and 4 have been specified with the aim of supporting service classes A, B, C, and D respectively. The VCLs (or VPLs) concatenated to form a VCC (or VPC) will all have the same QoS class as that of the VCC (or VPC). The Cell Loss Ratio (CLR), Cell Delay Variation (CDV), and end-to-end Cell Delay (CD) parameters are defined as part of QoS Class definition. In addition, an unspecified QoS Class numbered 0 is specified for best effort traffic. 7. 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. 7.1. 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, 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. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 12] Internet Draft ATM Management Objects February 4, 1994 The current specification of this ATM MIB is based on SNMPv2. 7.2. Structure of the MIB The managed ATM objects are arranged into the following groups: (1) ATM interface configuration group (2) ATM interface DS3 PLCP group (3) ATM interface TC Sublayer group (4) ATM interface virtual link (VPL/VCL) configuration groups (5) ATM VP/VC cross-connect groups (6) AAL5 connection performance statistics group 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. 7.3. ATM Interface Configuration Group This group 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. 7.4. ATM Interface DS3 PLCP and TC Layer Groups These groups 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. 7.5. ATM Virtual Link and Cross-Connect Groups ATM virtual link and cross-connect groups model bi-directional ATM virtual links and ATM cross-connects. The ATM VP/VC link groups 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 groups. Both link and cross-connect groups are implemented in a carrier's network for Customer Network Management (CNM) purposes. The ATM virtual link groups are used to create, delete or modify ATM virtual links in an ATM host, ATM switch and ATM Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 13] Internet Draft ATM Management Objects February 4, 1994 network. ATM virtual link groups along with the cross-connect groups are used to create, delete or modify ATM cross-connects in an ATM switch or ATM network (e.g., for CNM purposes). 8. Application of MIB II to ATM 8.1. The System Group For the purposes of the sysServices object in the System Group of MIB II [2], ATM is a data link layer protocol. Thus, for ATM switches and ATM networks, sysServices will have the value "2". 8.2. 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 [5] 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 [5]. 8.2.1. 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. Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 14] Internet Draft ATM Management Objects February 4, 1994 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 address for this interface. If an interface has multiple addresses, then this is its primary address. If an interface has no addresses, then this is an octet string of zero length. ifAdminStatus See [5]. ifOperStatus Assumes the value down(2) if the ATM cell layer or any layer below that layer is down. ifLastChange See [5]. 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. ifInErrors The number of cells dropped due to uncorrectable HEC 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 [5]. ifName Textual name of the interface or an octet string of zero length. ifLinkUpDownTrapEnable Default is disabled (2). ifConnectorPresent Set to false (2). ifPromiscuousMode Set to false(2).

Support of the AAL3/4 by RFC 1304 For the management of AAL3/4 CPCS layer, see RFC1304. [Note: RFC1304 is expected to be updated on this matter.] 10. Support of the AAL5 Managed Objects Support of AAL5 managed objects in an ATM switch and ATM host are described below. 10.1. 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 AAL5 in a switch is modeled as shown in Figures 4 and 5. 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 Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 16] Internet Draft ATM Management Objects February 4, 1994 be derived from the virtual channel cross-connect table and the virtual channel link table in the ATM MIB. ___________________________ | | | ============= | | | AAL5 | | | | Entity | | | ============= | | | | | -----Prop.

Managing AAL5 in a Host Managing AAL5 in a host involves managing the AAL5 sublayer interface as shown in Figures 6 and 7. The AAL5 sublayer is stacked directly over the ATM sublayer. The ifTable is applied to the AAL5 sublayer as defined in Section 10.3. ___________________________ | | | ============= | | | AAL5 | | | | Entity | | | ============= | | | ATM | | | | Entity | | | ============= | |___________|_____________| | __|__ ATM UNI | | v Figure 6 : Model of an AAL5 Entity in a Host __________________ | | | AAL5 | |________________| | | | ATM Layer | |________________| | | | Physical Layer| |________________| Figure 7 : AAL5 Entity's Interface Stack in a Host Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 18] Internet Draft ATM Management Objects February 4, 1994 10.3. 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 [13]. 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. ifSpeed Set to 0. ifPhysAddress An octet string of zero length. ifAdminStatus See [5]. ifOperStatus Assumes the value down(2) if the AAL5 or any layer below that layer is down. ifLastChange See [5]. ifInOctets The number of received AAL5 CPCS PDU octets. ifOutOctets The number of AAL5 CPCS PDU octets transmitted. ifInUcastPkts The number of received AAL5 CPCS PDUs passed to a higher-layer. ifOutUcastPkts The number of AAL5 CPCS PDUs received from a higher-layer for transmission.

ILMI MIB and The ATM Managed Objects The ILMI MIB is specified by the ATM Forum in UNI specification [12], to manage local ATM UNIs. The support of the ATM management functions by the ILMI MIB and those contained in this memo are compared in Table 1. In this table, "yes" in the "ILMI MIB" column indicates that the management functions are supported by the ILMI MIB. The MIB groups in the "This memo" column are the groups listed in Section 7.2. For that subset of management information which the ILMI MIB 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.

(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.

(2b) The manager characterizes the VCL's traffic parameters through setting the atmVclReceiveTrafficDescrIndex and the atmVclTransmitTrafficDescrIndex values in the VCL 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. (3) The manager activates the VCL by setting the the atmVclRowStatus to active(1).

This entry is used to model a bi-directional Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 56] Internet Draft ATM Management Objects February 4, 1994 ATM VP cross-connect which cross-connects two VPLs. 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 using the atmVpCrossConnectIndexValue 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 QoS Classes, i.e., the row creation fails if: - the requested topology is not supported by the agent, - the traffic/QoS 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 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.] Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 57] Internet Draft ATM Management Objects February 4, 1994 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 QoS Class 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 value of atmVpCrossConnectIndex is released by: (1) Setting atmVpCrossConnectRowStatus of all rows identified by this value of atmVpCrossConnectIndex to destroy(6). The agent may release all Masuma Ahmed and Kaj Tesink (editors) Expires 8/4/94 [Page 58] Internet Draft ATM Management Objects February 4, 1994 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 from to/from the VP topology as per the VP cross-connect establishment/retirement procedures. Reconfiguration of traffic/QoS parameter values requires release of the VP cross-connect before those parameter values may by changed for individual VPLs."
