At the ATM UNI, the maximum number of active VPI bits configured ranges from 0 to 8. Specifies the maximum number of active Virtual Channel Identifier (VCI) bits configured for this ATM interface. atminterfaceilmivpi AtmVpIdentifier Specifies the VPI value of the VCC that supports the Interim Local Management Interface (ILMI) at this ATM interface. If the values of atminterfaceilmivpi and atminterfaceilmivci are both equal to zero, ILMI is not supported at this ATM interface. atminterfaceilmivci AtmVcIdentifier Specifies the VCI value of the VCC that supports the ILMI at this ATM interface. If the values of atminterfaceilmivpi and atminterfaceilmivci are both equal to zero, ILMI is not supported at this ATM interface atminterfaceaddress Type INTEGER { private (1), nsape164 (2), nativee164 (3),other (4)} Specifies the type of primary ATM address that is configured for this ATM interface. Status: deprecated

4 ATM Interface Configuration Parameters Table Chapter 3 Table 3-2 ATM Interface Configuration Parameters Table MIB Objects (continued) atminterfaceadmin Address AtmAddr Specifies the primary address assigned for administrative purposes, for example, an address associated with the service provider side of a public network UNI. Thus, the value of this address corresponds with the value of ifphysaddress at the host side. If this interface has no assigned administrative address, or the address used for administrative purposes is the same as that used for ifphysaddress, this is an octet string of zero length. Status: deprecated Note The atminterfaceadminaddress object is replaced by atminterfacesubscraddress. atminterfacemyneighbor IpAddress IpAddress Specifies the IP address of the neighbor system that is connected to the far end of this interface. A Network Management Station can send SNMP messages as IP datagrams. These messages are sent to UDP port 161 to access network management information, which concerns the operation of the system. Note The value of this object is obtained in different ways, for example, manual configuration, or through ILMI interaction with the neighbor system. 3-4

5 Chapter 3 ATM Interface Configuration Parameters Table Table 3-2 ATM Interface Configuration Parameters Table MIB Objects (continued) atminterfacemyneighbor IfName DisplayString Specifies the textual name of the interface on the neighbor system on the far end of this interface and to where this interface connects. If the neighbor system is manageable through SNMP and supports the object ifname, the value of this object must be identical with ifname for the ifentry of the lowest-level physical interface for this port. If this interface does not have a textual name, the value of this object is a zero length string. Note The value of this object can be obtained in different ways, for example, manual configuration, or through ILMI interaction with the neighbor system. atminterfacecurrentmax VpiBits INTEGER (0..12) Determines the maximum number of VPI Bits that are currently used at this ATM interface. The value is the minimum of atminterfacemaxactivevpibits, and the atminterfacemaxactivevpibits of this interface UNI or NNI peer. If the interface does not negotiate with the peer to determine the number of VPI Bits that are used on the interface, the value of this object must equal atminterfacemaxactivevpibits. 3-5

The value is the minimum of atminterfacemaxactivevcibits, and the atminterfacemaxactivevcibits of this interface UNI or NNI peer. If the interface does not negotiate with the peer to determine the number of VCI Bits that is used on the interface, the value of this object must equal atminterfacemaxactivevcibits. Specifies the identifier that is assigned by a service provider to the network side of a public network UNI. If this interface has no assigned service provider address for other interfaces, this is an octet string of zero length. ATM Interface DS3 Physical Layer Convergence Procedure Table This table contains the DS3 Physical Layer Convergence Procedure (PLCP) configuration and state parameters for the ATM interfaces, which use DS3 PLCP for carrying ATM cells over DS3.

Contains the DS3 PLCP parameters and state variables at the ATM interface. It is indexed by the ifindex value of the ATM interface. The index contains ifindex. Specifies the number of DS3 PLCP Severely Errored Framing Seconds (SEFS). Each SEFS represents a one-second interval that contains one or more SEF events. Indicates if there is an alarm present for the DS3 PLCP. The following are the values: receivedfarendalarm Specifies the DS3 PLCP has received an incoming Yellow Signal. incominglof Specifies the DS3 PLCP has declared a loss of frame (LOF) failure condition. noalarm Specifies no alarms are present. A transition from the failure to the no alarm state occurs when no defects, for example, LOF, are received for more than ten seconds. Specifies the counter that is associated with the number of unavailable seconds encountered by PLCP. 3-7

If seven consecutive ATM cells have Header Error Control (HEC) violations, an OCD event occurs. A high number of OCD events can indicate a problem with the TC sublayer. Integer{noAlarm (1), lcdfailure(2)} Indicates if there is an alarm present for the TC sublayer. The following are the values used for the atminterfacetcalarmstate: lcdfailure(2) Indicates the TC sublayer is currently in the Loss of Cell Delineation (LCD) defect maintenance state. value noalarm(1) Indicates the TC sublayer is currently not in the LCD defect maintenance state. 3-9
