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. |
