CISCO-WAN-ATM-CONN-MIB: View SNMP OID List / Download MIB

This MIB is used for configuring/provisioning SPVCs on the ATM interfaces. This is used for ATM switch connection management. Terminologies used: GCRA - The Generic Cell Rate Algorithm(GCRA) is used to define comformance with repect to the traffic contract.For each cell arrival, the GCRA determines whether the cell conforms to the traffic contract of the connection. PCR - The Peak Cell Rate(PCR) traffic parameter specifies an upper bound on the rate at which traffic can be submitted on an ATM connection. SCR - Sustained Cell Rate. MBS - Maximum Burst Size. MCR - Minimum Cell Rate is the rate at which the source is always allowed to send. ACR - Allowed Cell Rate is the current rate at which a source is allowed to send. RDF - Rate Decrease Factor controls the decrease in the cell transmission rate CRM - Missing RM-cell count. CRM limits the number of forward RM-cells which may be sent in the absence of received backward RM-cells. CDF - The Cutoff Decrease Factor controls the decrease in ACR assoicated with the CRM. CDVT - Cell Delay Transfer Variation Tolerance CBR - The Constant Bit Rate(CBR) service category is used by connections that request a static amount of bandwidth that is continuously available during the connection lifetime. This amount of bandwidth is characterized by a PCR value. rt-VBR - The real-time Variable Bit Rate(rt-VBR) service category is intended for real-time applications, i.e.,those requiring tightly constrainded delay and delay variation, as would be appropriate for voice and video applications.The rt-VBR connections are characterized in terms of a PCR, SCR and MBS. nrt-VBR - The non-real-time Variable Bit Rate(nrt-VBR) service category is intended for non-real-time applications which have bursty traffic characteristics. The nrt-VBR is characterized in terms of a PCR,SCR and MBS. UBR - The Unspecified Bit Rate(UBR) service category is intended for non-real-time applications,i.e.,those not requiring tightly constrained delay and delay variation. The UBR service does not specify traffic related service gurantees. The UBR service is indicated by use of the Best Effort Indicator in ATM User Cell Rate Information element. ABR - The Available Bit Rate(ABR) is an ATM layer service category for which the limiting ATM layer transfer characteristics provided by the network may change subsequent to connection establishment. CAC - The Connection Admission Control(CAC) function is defined as the set of actions taken by the network at SVC establishment or by network management during PVC establishment in order to determine whether a connection can be progressed or should be rejected. UPC - Usage Parameter Control(UPC) is defined as the set of actions taken by the network to monitor and control traffic.

This table contains mandatory endpoint configuration for all SPVC connections.Most of the objects in this table are applicable to all provisioned endpoints for all service categories. The objects cwaChanAbrZZZ however, provide additional configuration information which apply to ABR endpoints only. Routing parameters 'cwaChanCDV', 'cwaChanCTD', 'cwaChanRemoteCDV', 'cwaChanRemoteCTD' and 'cwaChanMaxCost' cannot be set on a slave endpoint(i.e.if 'cwaChanRoutingMastership' is set to 'false').

An entry in the cwAtmChanCnfgTable. The each entry corresponds to a connection endpoint identified by interface(ifIndex),Virtual Path Identifier(VPI) and Virtual Channel Identifier(VCI). The ifIndex is for those entries in ifTable identified by ifType values atmVirtual(149) and propAtm(197).

The VPI value of a VP or VC connection. The cwaChanVpcFlag serves to distinguish if this is a VP/VC connection

The VCI value of VC connection. The cwaChanVpcFlag serves to distinguish if this is a VP/VC connection. For a VPC, the VCI is irrelevant and is set to a value of 0

This object identifies the service type to which this connection belongs. The service type specified is one among the ATM forum service types and implicitly determines the configuration for GCRA. This Object can be set only during row creation.

This object indentifies if the endpoint is a VP/VC endpoint. For a VPC, this object is set to true(1); For a VCC, this object is set to false(2). This Object can be set only during row creation.

This number represents a RESOURCE at the switch that has been assigned for this connection (identified by ifIndex, cwaChanVpi and cwaChanVci). An example of this resource could be the LCN/GLCN used by the switch. Another example could be a record number assigned for this connection in a database of records. When a connection gets deleted, this resource gets released into a free pool. When a new endpoint is added (different ifIndex, cwaChanVpi & cwaChanVci), the switch may re-assign this resource. Thus all connections in a switch would have an unique cwaChanIdentifier. Since the number of resources in the switch is a much lesser subset as compared to all possible combinations of ifIndex, vpi and vci, this number serves as a quick reference index between the switch and the NMS. This is especially useful during the configuration upload of connections from the switch to the NMS.

This counter tracks the number of configuration changes that happen on a specific endpoint (identified by ifIndex, cwaChanVpi, and cwaChanVci). The value of this object is derived from cwChanGlobalTransactionId. For every connection changes (add/delete/modify/up/down), the value of cwChanGlobalTransactionId is incremented and that value is used for this object. This counter is used by the NMS to determine if a connection configuration had been modified and requires an upload.

Limits imposed by software or hardware implementations could restrict the amount of statistical data that can be maintained in a physical entity (like a service module card). Hence there could be a need to restrict statistics collection to a smaller subset. This object serves the purpose of enabling/disabling statistics collection on a per connection basis. In implementations which do not have such limitations, this object can be set to true(1) for all connections. When set to true(1), statistics collection is enabled; When set to false(2), stats collection is disabled

This object serves to enable or disable continuity check(CC) on a connection endpoint. When continuity check is enabled on an endpoint, the endpoint anticipates OAM CC cells from its peer endpoint. OAM CC cells are sent when the peer endpoint does not have traffic cells to send. If the connection is idle and this endpoint has not received OAM CC cells for a period of 3.5 +/- 0.5 seconds, it declares continuity failure. This object serves to administratively control the CC feature. Typical implementations (of this feature) may choose to ignore this control or impose other conditions to actually enable CC cell flow. However, if this object is set to false(2), then this feature should be disabled

This object identifies the internal VPI assigned to a local endpoint, by the switch. The cwaChanLocalVpi, cwaChanLocalVci and the cwaChanLocalNSAPAddr, form a unique identifier for the connection endpoint in the networking domain

This object identifies the internal VCI assigned to a local endpoint, by the switch. The cwaChanLocalVpi, cwaChanLocalVci and the cwaChanLocalNSAPAddr, form a unique identifier for the connection endpoint in the networking domain

This object identifies the internal NSAP assigned to a local endpoint, by the switch. The cwaChanLocalVpi, cwaChanLocalVci and the cwaChanLocalNSAPAddr, form a unique identifier for the connection endpoint in the networking domain

This object identifies the VPI of the peer endpoint. The cwaChanRemoteVpi, cwaChanRemoteVpi and the cwaChanRemoteNSAPAddr, identify the peer endpoint in the networking domain. If the object 'cwaChanP2MP' is set to 'true', this object should not be 'set' and the value of this object, if any, is not meaningful. This Object can be set only during row creation.

This object identifies the VCI of the peer endpoint. The cwaChanRemoteVpi, cwaChanRemoteVpi and the cwaChanRemoteNSAPAddr, identify the peer endpoint in the networking domain. If the object 'cwaChanP2MP' is set to 'true', this object should not be 'set' and the value of this object, if any, is not meaningful. This Object can be set only during row creation.

This object identifies the NSAP of the peer endpoint. The cwaChanRemoteVpi, cwaChanRemoteVpi and the cwaChanRemoteNSAPAddr, identify the peer endpoint in the networking domain. If the object 'cwaChanP2MP' is set to 'true', this object should not be 'set' and the value of this object, if any, is not meaningful. This Object can be set only during row creation.

This object serves to associate an endpoint with a specific controller. Usually resource partitioning makes the association between a controller and a range of vpi-vci. There could be switches where hard partitioning of vpi-vci may not be implemented, in which case this object serves to tie a specific vpi-vci to a controller. This object can not be modified after the row is created.

This object, if set to true(1) identifies that this endpoint as the `master' endpoint of the connection. When set to false(2) this identifies the `slave' endpoint of the connection. The slave endpoint is the called party, while the master endpoint is the calling party in the SPVC call setup. The networking entity initiates routing of a SPVC connection only after a master endpoint is added. Mastership of a SPVC cannot be changed, once provisioned, implying that this object can be set only during row creation.

This object is used by the networking entity to select a route based on administrative weight of possible routes. Administrative weights of links and nodes contained in a path are aggregated and compared against this object. The networking entity prefers a path whose aggregate administrative weight is lesser than the value of this object. Setting this parameter to 0 indicates to the switch that only the best available route should be chosen. If this object is set to a value of 0xFFFFFFFF(4294967295), then switch ignore this metric in making routing decisions. This parameter is not allowed to be set on a slave endpoint. (i.e. if 'cwaChanRoutingMastership' is set to 'false').

This is used by the administrator to trigger the re-routing of the connection. * Rerouting takes effect, when this object is set to true(1). When set to false(2), no action is taken. * A get on this object always returns false(2). * When this object is set, no other object other than the RowStatus should be set in the MIB. * Reroute can be triggered only from the master endpoint. Any attempt to trigger reroute from the slave endpoint would result in a failure of the SET operation.

When set to true(1), enables the frame discard feature for the connection. This is applicable only to the master endpoint (cwaChanRoutingMastership is true) and only for VCC connections.

Reflects operational status of an endpoint. * This object is set to operFail(2), if the connection is not routed or if the endpoint receives AIS/RDI or if there is a CC failure. * If the connection is administratively down, this object would be set to adminDown(3). * For a normal case, this is set to operOk(1)

Initial cell rate: Rate at which a source should send initially after an idle period. The value must not be larger than the PCR

ACR Decrease Time Factor. This is the time permitted between sending RM-cells (Resource Mangement Cells) before the rate is decreased to ICR (Initial Cell Rate).

Rate Decrease Factor: Controls the rate decrease which occurs when backward RM-cells with CI=1 are received. Larger values lead to faster rate decrease. This factor is applied at both the local and remote endpoints, thus making the loop control symmetrical. Backward RM cells at the local endpoint correspond to RM cells received in the remote->local direction. Backward RM cells at the remote endpoint correspond to RM cells received in the local->remote direction.

Rate Increase Factor: Controls the rate increase which occurs when a backward RM-cell is received with CI=0 and NI=0. Larger values lead to faster rate increase This factor is applied at both the local and remote endpoints, thus making the loop control symmetrical. Backward RM cells at the local endpoint correspond to RM cells received in the remote->local direction. Backward RM cells at the remote endpoint correspond to RM cells received in the local->remote direction.

Maximum number of cells a source may send for each forward RM-cell Enumeration: 'nrm32': 5, 'nrm128': 7, 'nrm16': 4, 'nrm8': 3, 'nrm256': 8, 'nrm2': 1, 'nrm64': 6, 'nrm4': 2.

Upper bound on the time between forward RM-cells for an active source (in milliseconds) Enumeration: 'trm0point78125': 1, 'trm12point5': 5, 'trm25': 6, 'trm1point5625': 2, 'trm100': 8, 'trm3point125': 3, 'trm50': 7, 'trm6point25': 4.

Cutoff Decrease Factor: Controls the rate decrease associated with lost or delayed backward RM cells. Larger values result in faster rate decrease Enumeration: 'cdfOneOver8': 5, 'cdfOneOver2': 7, 'cdf0': 1, 'cdfOneOver4': 6, 'cdfOneOver64': 2, 'cdfOneOver16': 4, 'cdfOne': 8, 'cdfOneOver32': 3.

Transient Buffer Exposure. This is a negotiated number of cells that the network would like to limit the source to sending during startup periods, before the first RM-cell returns

Configuration of an endpoint for Explicit Rate Stamping. Refer the Textual convention for possible values

Abr connections require close loop control to limit the transmission rate, depending on the network bandwidth. Now this close loop can be end to end or between intermediate network segments. When terminating an Abr VPL, the endpoint needs to act like a Virtual Destination to the incoming traffic and generate backward RM cells. While doing this it also needs to act as a virtual source and send forward RM cells to the real destination. This is a feature that can be enabled/disabled under the control of this object. When set to true(1), this feature is enabled; and is disabled when set to false(2)

This object is used to create, modify or delete an entry in the ciscoWanAtmChanTable. * A row may be created using the 'CreateAndGo' option. When the row is successfully created, the RowStatus would be set to 'active' by the agent. Following mandatory objects need to be specified for the successful creation of the row(for both master and slave endpoints): cwaChanServiceCategory cwaChanVpcFlag cwaChanRoutingMastership Following mandatory objects are needed for creation of master endpoint: cwaChanRemoteVpi cwaChanRemoteVci cwaChanRemoteNSAPAddr * A row may be deleted by setting the RowStatus to 'destroy'. * When there is a need to administratively down the connection, the RowStatus could be set to 'notInService'. When the switch completes the 'down' operation, the value of this object would be 'notInService'. * The connection can be made active again, by setting this object to 'active'. * RowStatus modification from 'notInService' to 'active' or vice-versa will impact only the administrative status of the connection. * Administrative status control is limited to the master endpoint only. The switch would reject any request for administrative state change on the slave endpoint. * Other options such as `CreateAndWait' will not be used.

This object is used for enabling/disabling VSVD internal to a segment i.e the closed loop control is in effect between the two provisioned endpoints of the SPVC.

This object is used for enabling/disabling VSVD external to the segment which hosts the two endpoints of the SPVC i.e the closed loop control will be in effect outside the segment either towards a CPE or towards another segment.

This object is used for achieving OAM inter-operability between switches that cannot generate/detect segment AIS cells. This attribute enables the newer generation of switches to understand the OAM capability of the peer endpoint and accordingly generate/detect seg/e2e AIS as required. The value of this attribute is decided during provisioning time by network management.

Encoded value representing the maximum tolerable cell loss ratio in the direction local -> remote. The actual CLR value is derived as the negative logarithm of this value.

Encoded value representing the maximum tolerable cell loss ratio in the direction remote -> local. The actual CLR value is derived as the negative logarithm of this value. If the object 'cwaChanP2MP' is set to 'true', this object should not be 'set' and the value of this object, if any, is not meaningful.

This object controls the setting / resetting of the OAM segment endpoint. When set to OamSegEp (1), the SPVC endpoint would terminate all segment OAM FM cells and loopback all OAM segment loopback cells. When set to NonOamSegEp (2), the SPVC endpoint would be configured as a non-endpoint for OAM cells. This means that all OAM FM cells and loopback cells would pass transparently through this endpoint. If this object is not specified during a SET operation, the switch would apply a default configuration maintained for the port. Enumeration: 'nonOamSegEp': 2, 'oamSegEp': 1.

This object indicates whether a master endpoint has a persistent slave or not. A connection with a master and a non-persistent slave is considered a single-ended SPVC. This object is only meaningful when 'cwaChanRoutingMastership' contains the value of 'true(1)'. And this variable must be used with 'cwaChanRoutingMastership' to decide if a connection is single-ended or not. If the object 'cwaChanP2MP' is set to 'true', this object should not be 'set' and the value of this object, if any, is not meaningful. Enumeration: 'nonPersistentSlave': 2, 'persistentSlave': 1.

This object is the routing priority of the connection. When adding the connection, a default routing priority of 8 is used if this is not specified. This parameter is not allowed to be set at the slave endpoint(i.e. if 'cwaChanRoutingMastership' is set to 'false(2)'). Any attempt to change the priority at the slave endpoint would result in a failure of the SET operation. A connection tagged with a routing priority of 1 is routed (and derouted) ahead of connections tagged with other priorities.

This is used by the administrator to configure this master endpoint to be the root of a point-to-multipoint connection. When this variable is set to 'true', this master endpoint is the root of a point-to-multipoint connection. The objects 'cwaChanRemoteVpi', 'cwaChanRemoteVci', 'cwaChanRemoteNSAPAddr', 'cwaChanRemotePCR', 'cwaChanRemoteMCR' 'cwaChanRemoteSCR', 'cwaChanRemoteCDV', 'cwaChanRemoteCTD', 'cwaChanRemoteMBS', 'cwaChanRemoteCDVT', 'cwaChanRemotePercentUtil', 'cwaChanRemoteCLR' and 'cwaChanSlaveType' should not be set and the values of these objects are not meaningful. When this variable is set to 'false', this master endpoint is not a root of a point-to-multipoint connection. If the object 'cwaChanPrefRouteId' is non-zero, this object could not be set to true.

This object serves to to associate a preferred route with a connection. The value '0' means no preferred route is associated with this connection. Usage: - If the value of this set to 0, the object cwaChanDirectRoute is automatically set to FALSE by the switch. - The preferred route is defined in cwaPrefRouteConfTable object. If the object 'cwaChanP2MP' is true, this object could not be set to a non-zero value.

This object serves to associate a prefer route as directed route (correspond to the prefer route object cwaChanPrefRouteId). A directed route specifies that the associated preferred route is the only permission route for the connection to take. Should the associated preferred route be unavailable, the connection is failed. The object is not applicable if there is no associated preferred route with the connection.

An entry in cwAtmChanTestTable for each ATM Connection endpoints.

This object configures an endpoint in loopback: This is a mandatory object. * To configure a destructive loopback, this object needs to be set to destructive (2). The direction in which this destructive loopback needs to be effected, should be specified using the cwaChanTestDir object. To de-configure destructive loopback, this object needs to be set to noLpbk(1). * To configure a non-destructive loopback, this object needs to be set to nonDestructive(3). The direction in which this non-destructive loopback needs to be effected, should be specified using the cwaChanTestDir object. Non-destructive loopback gets de-configured automatically at the switch after a certain timeout. However, if there is a need to abort a non-destructive loopback, a set operation on this object should be performed with a value noLpbk (1). * Attempting to set a channel in loopback, when one is already in progress results in a failure of the set operation (with appropriate error code)

Specifies the direction in which loopback should be effected: This is a mandatory object. * For destructive loopback, this takes values external (1) and internal (2). * For non-destructive loopback, this takes values forward (3) and reverse (4). * When cwaChanTestType is noLpbk (1), this object is ignored.

Specifies number of loopback cells to inject. This applies to the non-destructive mode of loopback tests only. Get operation on this object returns the successful number of loopback iterations performed on the endpoint.

This object reflects the status of the last requested test: * If a loopback had never been effected on an endpoint, this object reads noStatus (1). * If a destructive mode of loopback is configured on an endpoint, this object always reads lpbkInEffect(6). * If a non-destructive mode of loopback is in progress, this reads lpbkInProgress(2). * If a non-destructive mode of loopback has completed successfully, this reads lpbkSuccess(3). * If a non-destructive mode of loopback has aborted, either due to user request or switch's limitation, this reads lpbkAbort (4). * If a non-destructive mode of loopback has failed, this reads lpbkTimeOut(5).

This object is applicable only for non-destructive mode of loopback. It returns the round trip delay measured during the last non-destructive loopback test

This object contains the number of VPCs currently in alarm. This object is intended only in traps/notifications.

This object contains the number of VCCs currently in alarm. This object is intended only in traps/notifications.

This table contains objects that are required for configuration upload. The configuration upload is a mechanism where the configuration(physical or logical information)of a switch is created in a file and that file is uploaded by the NMS application using file transfer method(for example FTP).

Entry containing generic information that apply to all provisined connections(ATM/Frame Relay).

This object's value generally corresponds to the Slot number where the module resides. However, System wide uniqueness is the only true requirement.

This reflects the transaction Identifier of the last successful connection configuration on the slot (represented by cwSlotIndex). The value of this object is incremented every time a connection(ATM/Frame Relay) is successfully added, deleted, modified or administratively up/down. The transaction identifier of the each provisioned ATM connection endpoint is represented by cwaChanUploadCounter in the cwaChanCnfgTable. The transcation identifer of the each provisioned Frame Relay connection endpoint is represented by frChanCnfChangeCount in frChanCnfGrpTable.
