The MIB objects are listed in Table 2-2.

Table 2-2 SONET/SDH Medium Table MIB Objects 

Name	Syntax	Description		Default Value
sonetMedium Table	SEQUENCE OF SonetMediumEntry	Describes the SONET/SDH Medium table. Max-Access: not-accessible Status: current		none
sonetMedium Entry	SonetMediumEntry	Provides an entry in the SONET/SDH Medium table. Max-Access: not-accessible Status: current The index is ifIndex.		none
sonetMediumType	INTEGER{sonet(1),sdh(2)}	Identifies whether a SONET or a SDH signal is used across this interface. Max-Access: read-write Status: current		none
sonetMedium TimeElapsed	Integer32 (1..900)	Determines the number of seconds, including partial seconds, elapsed since the beginning of the current measurement period. If an adjustment is made in the system's time-of-day clock, the current interval exceeds the maximum value. Therefore, the agent can return the maximum value. Max-Access: read-only Status: current		none
sonetMedium ValidIntervals	Integer32 (0..96)	Determines the number of previous 15-minute intervals for which the data is collected. A SONET/SDH interface must support at least n intervals. The minimum value of n is four. The default of n is 32. The maximum value of n is 96. For example, the value is n unless the measurement was restarted within the last (n*15) minutes. Then, the value is the number of the complete 15-minute intervals for which the agent has at least some data. For example, where the agent is a proxy, some intervals are unavailable. In this case, this interval is the maximum interval number for which data is available. Max-Access: read-only Status: current		none
sonetMediumLine Coding	INTEGER {sonetMediumOther(1), sonetMediumB3ZS(2), sonetMediumCMI(3), sonetMediumNRZ(4), sonetMediumRZ(5) }	Describes the line coding for this interface. The Binary 3-Zero Substitution (B3ZS) and Coded Mark Inversion (CMI) are used for electrical SONET/SDH signals (STS-1 and STS-3). The Non-Return to Zero (NRZ) and the Return to Zero are used for optical SONET/SDH signals. Max-Access: read-write Status: current		none
sonetMediumLine Type	INTEGER {sonetOther(1), sonetShortSingleMode(2), sonetLongSingleMode(3), sonetMultiMode(4), sonetCoax(5), sonetUTP(6)}	Describes the line type for this interface. The following are the line types: •Short and long range •Single mode fiber or Multi-mode fiber interfaces •Coax and UTP for electrical interfaces The value sonetOther is used when the Line Type is not one of the listed values. Max-Access: read-write Status: current		none
sonetMedium CircuitIdentifier	DisplayString (SIZE (0..255))	Contains the transmission vendor circuit identifier for troubleshooting. Note The circuit identifier, if available, is also represented by ifPhysAddress. Max-Access: read-write Status: current		none
sonetMedium InvalidIntervals	Integer32 (0..96)	Determines the number of intervals in the range from 0 to sonetMediumValidIntervals for which no data is available. This object is 0 except in cases where the data for some intervals are not available, for example, in proxy situations. Max-Access: read-only Status: current		none
sonetMediumLoopbackConfig	BITS {sonetNoLoop(0), sonetFacilityLoop(1), sonetTerminalLoop(2), sonetOtherLoop(3)}	Describes the current loopback state of the SONET/SDH interface. The values include: •sonetNoLoop—Means not in the loopback state. A device that is not capable of performing a loopback on this interface can always return this value. •sonetFacilityLoop—Ensures that the received signal at this interface is looped back out through the corresponding transmitter in the return direction. •sonetTerminalLoop—Ensures that the signal about to be transmitted is connected to the associated incoming receiver. •sonetOtherLoop—Defines the loopbacks. Max-Access: read-write Status: current		none
sonetSESthresholdSet	INTEGER {other(1), bellcore1991(2), ansi1993(3), itu1995(4), ansi1997(5)}	Specifies an enumerated integer that indicates the recognized set of Severely Errored Seconds (SES) thresholds, which the agent uses for determining severely errored seconds and unavailable time.

Table 2-27 DS3/E3 Configuration Table MIB Objects 

Name	Syntax	Description			Default Value
dsx3ConfigTable	Sequence of Dsx3ConfigEntry	Describes the DS3/E3 configuration table. Max-Access: not-accessible Status: current			none
dsx3ConfigEntry	dsx3ConfigEntry	Provides an entry in the DS3/E3 configuration table. Max-Access: not-accessible Status: current The index is dsx3LineIndex.			none
dsx3LineIndex	InterfaceIndex	Equals ifIndex. ds3xIfIndex describes its previous usage. By making the object equal to ifIndex, it allows proper use of ifStackTable. Previously, this object was the identifier of a DS3/E3 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS3/E3 interface, it can have the same value as ifIndex. Otherwise, number the dsx3LineIndices with a unique identifier following the rules of choosing a number that is greater than ifNumber and numbering the inside interfaces (for example, equipment side) with even numbers, and outside interfaces (for example, network side) with odd numbers. Max-Access: read-only Status: current			none
dsx3IfIndex	InterfaceIndex	Specifies the value for this object is equal to the value of ifIndex from the Interfaces table of MIB II (RFC 1213). Max-Access: read-only Status: deprecated			none
dsx3TimeElapsed	INTEGER (0..899)	Determines the number of seconds that have elapsed since the beginning of the near end current error-measurement period. If, for some reason, such as an adjustment in the system time-of-day clock, the current interval exceeds the maximum value, the agent will return the maximum value. Max-Access: read-only Status: current			none
dsx3ValidIntervals	INTEGER (0..96)	Determines the number of previous near end intervals for which data was collected. The value is 96 unless the interface was brought online within the last 24 hours, in which case the value will be the number of complete 15-minute near end intervals since the interface has been online. In the case where the agent is a proxy, some intervals may not be available. In this case, this interval is the maximum interval number for which data is available. Max-Access: read-only Status: current			none
dsx3LineType	INTEGER {dsx3other(1), dsx3M23(2), dsx3SYNTRAN(3), dsx3CbitParity(4), dsx3ClearChannel(5), e3other(6), e3Framed(7), e3Plcp(8)}	Indicates the variety of DS3 C-bit or E3 application implementing this interface. The type of interface affects the interpretation of usage and error statistics. The rate of DS3 is 44.736 Mbps and E3 is 34.368 Mbps. The dsx3ClearChannel value means that the C-bits are not used except for sending/receiving Alarm Indication Signal (AIS). Max-Access: read-write Status: current The specifications for each line type include:			none
		dsx3 Line Type	Specification
		dsx3M23	ANSI T1.107-1988 [9]

dsx3LineCoding	INTEGER {dsx3Other(1), dsx3B3ZS(2), e3HDB3(3)}	Describes the variety of Zero Code Suppression used on this interface, which in turn affects a number of its characteristics. dsx3B3ZS and e3HDB3 refer to the specified patterns of normal bits and bipolar violations, which are used to replace sequences of 0 bits of a specified length. Max-Access: read-write Status: current			none
dsx3SendCode	INTEGER {dsx3SendNoCode(1), dsx3SendLineCode(2), dsx3SendPayloadCode(3), dsx3SendResetCode(4), dsx3SendDS1Loop Code(5), dsx3SendTestPattern(6)}	Indicates the type of code the device is sending across the DS3/E3 interface. Note These are optional for E3 interfaces. Setting this variable causes the interface to begin sending the code requested. Max-Access: read-write Status: current			none
dsx3Circuit Identifier	DisplayString (SIZE (0..255))	Contains the transmission vendor circuit identifier, which facilitates troubleshooting. Max-Access: read-write Status: current			none

		dsx3 Loopback Configuration	Definition
		dsx3NoLoop	Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return back the value.
		dsx3Payload Loop	The received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it has passed through the device framing function.
		dsx3LineLoop	The received signal at this interface does not go through the device (minimum penetration) but is looped back out.
		dsx3OtherLoop	Loopbacks that are not defined here.
		dsx3InwardLoop	The sent signal at this interface is looped back through the device.
		dsx3DualLoop	Both dsx1LineLoop and dsx1InwardLoop are active simultaneously.
dsx3LineStatus	INTEGER (1..4095)	Indicates the line status of the interface. It contains loopback state information and failure state information. The dsx3LineStatus is a bitmap represented as a sum, therefore, it can represent multiple failures and a loopback (see the dsx3LoopbackConfig object for the type of loopback) simultaneously. The dsx3NoAlarm must be set if no other flag is set. If the dsx3loopbackState bit is set, the loopback in effect can be determined from the dsx3loopbackConfig object. Max-Access: read-only Status: current The various bit positions include:			none
		Bit Position	Line Status	Meaning
		1	dsx3NoAlarm	No alarm present

dsx3LineLength	INTEGER (0..64000) (in units of meters)	Determines the length of the DS3 line in meters. This object provides information for line build out circuitry. Max-Access: read-write Status: current			none
dsx3LineStatusLastChange	TimeStamp	Determines the value of the MIB IF sysUpTime object at the time this DS3/E3 entered its current line status. If the current state was entered prior to the last reinitialization of the proxy agent, this object contains a 0 value. Max-Access: read-only Status: current			none
dsx3LineStatus ChangeTrapEnable	INTEGER {enabled(1), disabled(2)}	Indicates whether dsx3LineStatusChange traps are generated for this interface. Max-Access: read-write Status: current			disabled
dsx3Loopback Status	INTEGER (1..127)	Represents the current state of the loopback on the DS3 interface. The variable contains information about loopbacks established by a manager remotely from the far end.

		64	dsx3FarEndLineLoopback
dsx3Channelization	INTEGER {disabled(1), enabledDs1(2), enabledDs2(3)}	Indicates whether this DS3/E3 is channelized or unchannelized. The value of enabledDs1 indicates that this is a DS3 channelized into DS1s. The value of enabledDs3 indicates that this is a DS3 channelized into DS2s. Setting this object causes the creation or deletion of DS2 or DS1 entries in the ifTable. Max-Access: read-write Status: current			none
dsx3Ds1ForRemote Loop	INTEGER (0..29)	Indicates which DS1/E1 on this DS3/E3 is indicated in the remote DS1 loopback request. A value of 0 means no DS1 is looped. A value of 29 means all DS1/E1s are looped. Max-Access: read-write Status: current			none

Interfaces Group MIB Objects

This section describes the Interfaces Group MIB modules, which reside in the IF-MIB.my file. The MIB objects are extracted from RFC 2233 and describe the generic network interface sublayers. These MIB objects are an updated version of MIB-II's ifTable, and incorporate the extensions defined in
RFC 1229.

---

Note The IF MIB is supported by AXSM, AXSM-E, PXM45, and RPM, which is also implemented in PXM45.

---

The Interfaces Group MIB include:

•Textual Conventions

•Interface Index

•Interfaces Table

•Extension to the Interface Table

•High Capacity Counters

•Generic Receive Address Table

•Interface-Related Traps

•Interfaces Group Conformance Information

Textual Conventions

The names of the textual conventions are specified in the object syntax.

The object identifiers are listed in Table 2-49.

Table 2-49 Interfaces Group Textual Convention Object Identifiers

Name	Object Identifier
ifNumber	::= {interfaces 1}
fTableLastChange	::= {ifMIBs 5}

The MIB objects are listed in Table 2-50.

Table 2-50 Interfaces Group Textual Convention MIB Objects 

Name	Syntax	Description		Default Value
OwnerString1	OCTET STRING (SIZE(0..255))	Specifies the data type that is used to model an administratively assigned name of the owner of a resource. This information is taken from the NVT ASCII character set. It is suggested that this name contain one or more of the following: •ASCII form of the manager station's transport address. •Management station name (for example, domain name). •Network management personnel name, location, or phone number. In some cases the agent itself will be the owner of an entry. In these cases, this string can be set to a string starting with agent. Display Hint: 255a Status: current		none
InterfaceIndex1	Integer32 (1..2147483647)	Contains the semantics of ifIndex and is used for any syntax defined on other MIB modules that need these semantics. Specifies a unique value, greater than 0, for each interface or interface sublayer in the managed system. It is recommended that values be assigned contiguously starting from 1. The value for each interface sublayer must remain constant at least from one reinitialization of the entity's network management system to the next reinitialization. Display Hint: d Status: current		none
InterfaceIndexOr Zero1	Integer32 (0..2147483647)	Specifies an extension of the InterfaceIndex convention. The latter defines a greater than 0 value used to identify an interface or interface sublayer in the managed system. This extension permits the additional value of 0. The value 0 is specific and must therefore be defined as part of the description. Examples of the use of 0 include situations where interface was unknown, or when none or all interfaces need to be referenced. Display Hint: d Status: current		none
ifNumber	Integer32	Determines the number of network interfaces (regardless of their current state) present on this system. Max-Access: read-only Status: current		none
ifTableLastChange	TimeTicks	Specifies the value of sysUpTime at the time of the last creation or deletion of an entry in the ifTable. If the number of entries has been unchanged since the last reinitialization of the local network management subsystem, this contains a 0 value. Max-Access: read-only Status: current		none

1 Object identifier is not supported.

Interface Index

The interface index contains the semantics of the ifIndex and is used for any objects defined on other mib modules that need these semantics.

The object identifier for each MIB object is listed in Table 2-51.

Table 2-51 Interface Index Object Identifiers 

Name	Object Identifier
OwnerString	none
InterfaceIndex	none
InterfaceIndexOrZero	none
ifNumber	::= { interfaces 1 }
ifTableLastChange	::= { ifMIBObjects 5 }

The MIB objects are listed in Table 2-52.

Table 2-52 Interface Index MIB Objects 

Name	Syntax	Description		Default Value
OwnerString	OCTET STRING (SIZE(0..255))	Uses a model of an administratively-assigned name of the resource owner for this data type. This information is taken from the NVT ASCII character set. It is suggested that this name contain one or more of the following: •ASCII form of the manager station's transport address. •Management station name (for example, domain name). •Network management personnel name, location, or phone number. In some cases, the agent itself is the owner of an entry. In these cases, start of the string can be the agent substring. InterfaceIndex contains the semantics of ifIndex and is used for any syntax defined on other MIB modules that need these semantics. Display Hint: 255a Status: current		none
InterfaceIndex	Integer32 (1..2147483647)	Specifies a unique value, greater than 0, for each interface or interface sublayer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sublayer must remain constant at least from one reinitialization of the entity network management system to the next reinitialization. Display Hint: d Status: current		none
InterfaceIndexOrZero	Integer32 (0..2147483647)	Specifies an extension of the InterfaceIndex convention for this textual convention. The latter defines a greater than 0 value used to identify an interface or interface sublayer in the managed system. This extension permits the additional value of 0. The 0 value is specific and must therefore be defined as part of the description of any object using this syntax. Examples of the use of 0 include situations when the interface was unknown, or when none or all interfaces are referenced. Display Hint: d Status: current		none
ifNumber	Integer32	Determines the number of network interfaces (regardless of their current state) present on this system. Max-Access: read-only Status: current		none
ifTableLastChange	TimeTicks	Determines the value sysUpTime at the last creation or deletion of an entry in the ifTable. If the number of entries are unchanged since the last reinitialization of the local network management subsystem, this contains a 0 value. Max-Access: read-only Status: current		none

Interfaces Table

The Interfaces Table contains information on the entity interfaces. Each sublayer below the internetwork layer of a network interface is considered to be an interface.

The object identifiers are listed in Table 2-53.

The MIB objects are listed in Table 2-54.

Table 2-54 Interfaces Table MIB Objects 

Name	Syntax	Description		Default Value
ifTable	Sequence of IfEntry	Lists the interface entries. The number of entries is given by the value of ifNumber. Max-Access: not-accessible Status: current		none
ifEntry	ifEntry	Provides an entry containing management information applicable to a particular interface. Max-Access: not-accessible Status: current The index is ifIndex.		none
ifIndex	InterfaceIndex	Specifies a unique value, greater than 0, for each interface. It is recommended that values are assigned starting with 1. The value for each interface sublayer must remain constant at least from one reinitialization of the entity's network management system to the next reinitialization. Max-Access: read-only Status: current		none
ifDescr	DisplayString (SIZE (0..255))	Specifies a textual string containing information about the interface. This string includes the name of the manufacturer, the product name, and the version of the interface hardware or software. Max-Access: read-only Status: current		none
ifType	IANAifType	Describes the type of interface. Additional values for ifType are assigned by the Internet Assigned Numbers Authority (IANA), through updating the Syntax of the IANAifType textual convention. Max-Access: read-only Status: current		none
ifMtu	Integer32	Determines the size of the largest packet, which is sent/received on the interface. It is specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that is sent on the interface. Max-Access: read-only Status: current		none
ifSpeed	Gauge32	Determines the estimate of the interface current bandwidth in bps. For interfaces which do not vary in bandwidth, or for those where no accurate estimation can be made, this can contain the nominal bandwidth. If the bandwidth of the interface is greater than the maximum value, the maximum value (4,294,967,295) and ifHighSpeed must be used to report the interface speed. For a sublayer which has no bandwidth, the value is 0. Max-Access: read-only Status: current		none
ifPhysAddress	PhysAddress	Specifies the interface address at its protocol sublayer. For example, an 802.x interface contains a MAC address. The interface media-specific MIB must define the bit and byte ordering and the format of the value of this address. For interfaces which do not have such an address, for example, a serial line, can contain an octet string of 0 length. Max-Access: read-only Status: current		none
ifAdminStatus	Integer {up (1), ready to pass packets down; (2), testing; (3) in some test mode}	Describes the desired state of the interface. The testing(3) state indicates that no operational packets are passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2) state. As a result of either explicit management action or through configuration information retained by the managed system, ifAdminStatus is changed to either the up(1), testing(3), or remains in the down(2) state. Max-Access: read-write Status: current		none
ifOperStatus	Integer {up (1), ready to pass packets; down(2); testing (3), in some test mode; unknown (4), status can not be determined; dormant (5); notPresent (6), some component is missing; lowerLayerDown (7), down due to state of lower-layer interface(s)}	Describes the current operational state of the interface. The testing (3) state indicates that no operational packets can be passed. If ifAdminStatus is changed to down (2), ifOperStatus changes to down(2). If the ifAdminStatus object is changed to up (1), ifOperStatus changes to up(1). If the interface is ready to transmit and receive network traffic; it can change to dormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection). It remains in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state. It remains in the notPresent (6) state if the interface has missing components typically hardware. Max-Access: read-only Status: current		none
ifLastChange	TimeTicks	Specifies the value of sysUpTime when the interface entered its current operational state. If the current state was entered before the last reinitialization of the local network management subsystem, this contains a 0 value. Max-Access: read-only Status: current		none
ifInOctets	Counter32	Determines the total number of octets received on the interface, including framing characters. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifInUcastPkts	Counter32	Determines the number of packets delivered by this sublayer to a higher sublayer, which are not addressed to a multicast or broadcast address at this sublayer. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifInNUcastPkts	Counter32	Determines the number of packets delivered by this sublayer to a sublayer, which are addressed to a multicast or broadcast address at this sublayer. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. This is discontinued in favor of ifInMulticastPkts and ifInBroadcastPkts. Max-Access: read-only Status: deprecated		none
ifInDiscards	Counter32	Determines the number of inbound packets that were chosen to be discarded (even though no errors had been detected) to prevent their being deliverable to a higher layer protocol. One possible reason for discarding such a packet could be to free buffer space. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifInErrors	Counter32	Determines the number of inbound packets that contained errors preventing them from being delivered to a higher layer protocol for packet-oriented interfaces. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher layer protocol. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifInUnknown Protos	Counter32	Determines the number of packets received through the interface that were discarded because of an unknown or unsupported protocol for packet-oriented interfaces. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received through the interface that were discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter is always 0. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifOutOctets	Counter32	Determines the total number of octets transmitted out of the interface, including framing characters.

Max-Access: read-only Status: current		none
ifOutUcastPkts	Counter32	Determines the total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifOutNUcast Pkts	Counter32	Determines the total number of packets that higher-level protocols requested be transmitted, and that were addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. This is discontinued in favor of ifOutMulticastPkts and ifOutBroadcastPkts. Max-Access: read-only Status: deprecated		none
ifOutDiscards	Counter32	Determines the number of outbound packets that were chosen to be discarded (even though no errors had been detected) to prevent their being transmitted. One possible reason for discarding such a packet is to free buffer space. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifOutErrors	Counter32	Determines the number of outbound packets that cannot be transmitted because of errors for packet-oriented interfaces. For character-oriented or fixed-length interfaces, the number of outbound transmission units that can not be transmitted because of errors. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifOutQLen	Gauge32	Determines the length of the output packet queue (in packets). Max-Access: read-only Status: deprecated		none
ifSpecific	IDENTIFIER	Points to an instance of a MIB in the media-specific MIB, for example, the semantics associated with the Instance Pointer textual convention defined in RFC 1903. It is recommended that the media-specific MIB specify what value ifSpecific can take for values of ifType. If no MIB definitions specific to the particular media are available, the value is set to the IDENTIFIER {0 0}. Max-Access: read-only Status: deprecated		none

For a MAC layer protocol, this includes both group and functional addresses. This is a 64-bit version of ifInMulticastPkts. The discontinued value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifHCInBroadcastPkts	Counter64	Determines the number of packets delivered by this sublayer to a higher sublayer that were addressed to a broadcast address. This is a 64-bit version of ifInBroadcastPkts. The discontinued value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifHCOutOctets	Counter64	Determines the total number of octets transmitted out of the interface, which includes framing characters. This is a 64-bit version of ifOutOctets. The discontinued value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifHCOutUcastPkts	Counter64	Determines the total number of packets that higher-level protocols requested be transmitted. The packets are not addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent. This is a 64-bit version of ifOutUcastPkts. The discontinued value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifHCOutMulticastPkts	Counter64	Determines the total number of packets that higher-level protocols requested be transmitted. The packets are addressed to a multicast address at this sublayer, including those that were discarded or not sent. For a MAC layer protocol, this includes both group and functional addresses. This is a 64-bit version of ifOutMulticastPkts.

Max-Access: read-only Status: current		none
ifHCOutBroadcastPkts	Counter64	Determines the total number of packets that higher-level protocols requested be transmitted. The packets are addressed to a broadcast address at this sublayer, including those that were discarded or not sent. This is a 64-bit version of ifOutBroadcastPkts. The discontinued value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. Max-Access: read-only Status: current		none
ifLinkUpDownTrap Enable	Integer {enabled (1), disabled (2)}	Indicates whether linkUp or linkDown traps are generated for this interface. By default, this can have the value enabled (1) for interfaces which do not operate on top of any other interface (as defined in the ifStackTable), and disabled (2). Max-Access: read-write Status: current		none
ifHighSpeed	Gauge32	Determines an estimate of the interface current bandwidth in units of 1,000,000 bps. If this reports a value of n, the speed of the interface is somewhere in the range of n-500,000 to n+499,999. For interfaces that do not vary in bandwidth or for which no accurate estimation is made, this contains the nominal bandwidth. For a sublayer that has a defined bandwidth, the value is 0. Max-Access: read-only Status: current		none
ifPromiscuousMode	TruthValue	Defines a value of false (2) if the interface accepts only packets and frames that are addressed to this station. It has a value of true (1) when the station accepts all packets and frames transmitted on the media. The value of true (1) is valid only on certain types of media. If valid, setting this to a value of true (1) requires the interface to be reset before becoming effective. The value of ifPromiscuousMode does not affect the reception of broadcast and multicast packets and frames by the interface. Max-Access: read-write Status: current		none
ifConnectorPresent	TruthValue	Defines the value true (1) if the interface sublayer has a physical connector and the value false (2). Max-Access: read-only Status: current		none
ifAlias	DisplayString (SIZE(0..64))	Defines an alias for the interface as specified by a network manager, and provides a nonvolatile handle for the interface. On the first instance of an interface, the value of ifAlias associated with that interface is the zero-length string. When a value is written into an instance of ifAlias through a network management set operation, the agent must retain the supplied value in the ifAlias instance. It is associated with the same interface for as long as that interface remains instantiated. The following are included: •All reinitializations and reboots of the network management system. •Change of the interface ifIndex value. An example of the value that a network manager can store for a WAN interface is the Telco circuit number and identifier of the interface. Some agents can support write-access only for interfaces having particular values of ifType. An agent that supports write access is required to keep the value in nonvolatile storage. But it can limit the length of new values, depending on how much storage is already occupied by the values for other interfaces. Max-Access: read-write Status: current		none
ifCounterDiscontinuityTime	TimeStamp	Specifies the value of sysUpTime on the most recent occasion when any of the interface counters suffered a discontinuity. The relevant counters are the specific instances associated with this interface of any Counter32 or Counter64 contained in the ifTable or ifXTable. If no discontinued counter values occurred since the last reinitialization of the local management subsystem, this value is 0. Max-Access: read-only Status: current		none
