ATM-TC-MIB

This MIB Module provides Textual Conventions and OBJECT-IDENTITY Objects to be used by ATM systems.

Typedef Base type Abstract
AtmAddr string An ATM address. The semantics are implied by the length. The address types are: - no address (0 octets) - E.164 (8 octets) - NSAP (20 octets) In addition, when subaddresses are used the AtmAddr may represent the concatenation of address and subaddress. The associated address types are: - E.164, E.164 (16 octets) - E.164, NSAP (28 octets) - NSAP, NSAP (40 octets) Address lengths other than defined in this definition imply address types defined elsewhere. Note: The E.164 address is encoded in BCD format.
AtmConnCastType enumeration The type of topology of a connection (point- to-point, point-to-multipoint). In the case of point-to-multipoint, the orientation of this VPL or VCL in the connection. On a host: - p2mpRoot indicates that the host is the root of the p2mp connection. - p2mpLeaf indicates that the host is a leaf of the p2mp connection. On a switch interface: - p2mpRoot indicates that cells received by the switching fabric from the interface are from the root of the p2mp connection. - p2mpLeaf indicates that cells transmitted to the interface from the switching fabric are to the leaf of the p2mp connection.
AtmConnKind enumeration The type of call control used for an ATM connection at a particular interface. The use is as follows: pvc(1) Virtual link of a PVC. Should not be used for an PVC/SVC (i.e., Soft PVC) crossconnect. svcIncoming(2) Virtual link established after a received signaling request to setup an SVC. svcOutgoing(3) Virtual link established after a transmitted or forwarded signaling request to setup an SVC. spvcInitiator(4) Virtual link at the PVC side of an SVC/PVC crossconnect, where the switch is the initiator of the Soft PVC setup. spvcTarget(5) Virtual link at the PVC side of an SVC/PVC crossconnect, where the switch is the target of the Soft PVC setup. For PVCs, a pvc virtual link is always cross- connected to a pvc virtual link. For SVCs, an svcIncoming virtual link is always cross- connected to an svcOutgoing virtual link. For Soft PVCs, an spvcInitiator is either cross-connected to an svcOutgoing or an spvcTarget, and an spvcTarget is either cross-connected to an svcIncoming or an spvcInitiator.
AtmIlmiNetworkPrefix binary A network prefix used for ILMI address registration. In the case of ATM endsystem addresses (AESAs), the network prefix is the first 13 octets of the address which includes the AFI, IDI, and HO-DSP fields. In the case of native E.164 addresses, the network prefix is the entire E.164 address encoded in 8 octets, as if it were an E.164 IDP in an ATM endsystem address structure.
AtmInterfaceType enumeration The connection setup procedures used for the identified interface. Other: Connection setup procedures other than those listed below. Auto-configuration: Indicates that the connection setup procedures are to be determined dynamically, or that determination has not yet been completed. One such mechanism is via ATM Forum ILMI auto-configuration procedures.

AtmServiceCategory enumeration The service category for a connection.
AtmSigDescrParamIndex int32 The value of this object identifies a row in the atmSigDescrParamTable. The value 0 signifies that none of the signalling parameters defined in the atmSigDescrParamTable are applicable.
AtmTrafficDescrParamIndex int32 The value of this object identifies a row in the atmTrafficDescrParamTable. The value 0 signifies that no row has been identified.
AtmVcIdentifier int32 The VCI value for a VCL. The maximum VCI value cannot exceed the value allowable by atmInterfaceMaxVciBits defined in ATM-MIB.
AtmVorXAdminStatus enumeration The value determines the desired administrative status of a virtual link or cross-connect. The up and down states indicate that the traffic flow is enabled or disabled respectively on the virtual link or cross-connect.
AtmVorXLastChange uint32 The value of MIB II's sysUpTime at the time a virtual link or cross-connect entered its current operational state. If the current state was entered prior to the last re-initialization of the agent then this object contains a zero value.
AtmVorXOperStatus enumeration The value determines the operational status of a virtual link or cross-connect. The up and down states indicate that the traffic flow is enabled or disabled respectively on the virtual link or cross-connect. The unknown state indicates that the state of it cannot be determined. The state will be down or unknown if the supporting ATM interface(s) is down or unknown respectively.
AtmVpIdentifier int32 The VPI value for a VPL or VCL. The value VPI=0 is only allowed for a VCL. For ATM UNIs supporting VPCs the VPI value ranges from 0 to 255. The VPI value 0 is supported for ATM UNIs conforming to the ATM Forum UNI 4.0 Annex 8 (Virtual UNIs) specification. For ATM UNIs supporting VCCs the VPI value ranges from 0 to 255. For ATM NNIs the VPI value ranges from 0 to 4095. The maximum VPI value cannot exceed the value allowable by atmInterfaceMaxVpiBits defined in ATM-MIB.
