Description: LBHUB-BLC-MIB module

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is LBHUB-BLC-MIB?

LBHUB-BLC-MIB is a legacy 3Com proprietary MIB (enterprise OID 43) extending the standard IF-MIB/dot3 (Ethernet-like) MIB with additional interface and Ethernet-collision statistics for a hub/repeater product ('BLC'). Its extended-interface table records chip set, firmware revision, multicast/broadcast transmitted/received counts, promiscuous-mode flag, and a receive-address table, while a dot3 table records MAC initialization, sublayer status, multicast-receive status, transmit-enable, TDR (Time Domain Reflectometry, cable-fault-location) test value, and standard dot3 statistics. As a hardware/performance-status MIB it lets an administrator run a TDR test to locate a cable fault and watch collision-related statistics. It is deployed on legacy 3Com hub/repeater equipment. Engineers can download the LBHUB-BLC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LBHUB-BLC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

dot3	1.3.6.1.2.1.10.7
dot3Table	1.3.6.1.2.1.10.7.1		not-accessible	Status information and control variables for a collection of ethernet-like interfaces attached to a particular system.
dot3Entry	1.3.6.1.2.1.10.7.1.1		not-accessible	Status information and control variables for a particular interface to an ethernet-like medium.
INT dot3Index	1.3.6.1.2.1.10.7.1.1.1	INTEGER	read-only	An index value that uniquely identifies an interface to an ethernet-like medium. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
INT dot3InitializeMac	1.3.6.1.2.1.10.7.1.1.2	INTEGER	read-write	The initialization status of the MAC and PLS (Physical Layer Signalling) subsystems for a particular interface. The value initialized(1) signifies that the subsystems for a particular interface have been previously initialized; the value uninitialized(2) signifies that they have not been previously initialized. Each alteration of an instance of this object to either of the values initialized(1) or uninitialized(2) is analogous to an invocation of the initializeMAC action defined in [9] and has the effect of (re-)initializing the MAC and PLS subsystems for the associated interface. In particular, all management counters pertaining to the MAC and PLS subsystems for said interface are reset to zero; the receive and transmit layer management state variables (receiveEnabled and transmitEnabled in [9]) are set to enable reception and transmission of frames; the promiscuous receive function is disabled; and multicast reception is disabled.
INT dot3MacSubLayerStatus	1.3.6.1.2.1.10.7.1.1.3	INTEGER	read-write	The operational status of the MAC sublayer for a particular interface. The value enabled(1) signifies that the MAC sublayer for said interface is operational for both transmitting and receiving frames -- that is, that the value of both the receive and transmit layer management state variables (receiveEnabled and transmitEnabled in [9]) for said interface are true. The value disabled(2) signifies that the MAC sublayer for said interface is not operational for either transmitting or receiving frames. In particular, the value of an instance of this object is disabled(2) whenever the value of the corresponding instance of the dot3Enabled object is false(2). Each alteration of an instance of this object to the value enabled(1) is analogous to an invocation of the enableMACSublayer action defined in [9] and has the effect of starting normal transmit and receive operations (from the ``idle'' state) on the associated interface. In particular, such an alteration has the effect of resetting the PLS for said interface and of setting the receive and transmit layer management state variables (receiveEnabled and transmitEnabled in [9]) to be true. Each alteration of an instance of this object to the value disabled(2) is analogous to an invocation of the disableMACSublayer action defined in [9] and has the effect of terminating transmit and receive operations on the associated interface. In particular, such an alteration has the effect of setting the receive and transmit layer management state variables (receiveEnabled and transmitEnabled in [9]) to be false. Any transmissions/receptions in progress are completed before operation is terminated.
INT dot3MulticastReceiveStatus	1.3.6.1.2.1.10.7.1.1.4	INTEGER	read-write	The multicast receive status for a particular interface. The value enabled(1) signifies that reception of multicast frames by the MAC sublayer is enabled on said interface. The value disabled(2) signifies that reception of multicast frames by the MAC sublayer is not enabled on said interface. Each alteration of an instance of this object to the value enabled(1) is analogous to an invocation of the enableMulticastReceive action defined in [9] and has the effect of enabling multicast frame reception on the associated interface. Actual reception of multicast frames is only possible on an interface when the values for the associated instances of the dot3MulticastReceiveStatus and dot3MacSubLayerStatus objects are enabled(1) and enabled(1), respectively. Each alteration of an instance of this object to the value disabled(2) is analogous to an invocation of the disableMulticastReceive action defined in [9] and has the effect of inhibiting multicast frame reception on the associated interface.
INT dot3TxEnabled	1.3.6.1.2.1.10.7.1.1.5	INTEGER	read-write	The transmit layer management state variable (transmitEnabled as defined in [9]) for a particular interface. The value true(1) signifies that the MAC frame transmission is enabled on said interface. The value false(2) signifies that the MAC frame transmission is inhibited on said interface. In particular, the value of an instance of this object is false(2) whenever the value of the corresponding instance of the dot3MacSubLayerStatus object is disabled(2). Each alteration of an instance of this object to the value true(1) is analogous to an invocation of the enableTransmit action defined in [9] and has the effect of enabling MAC sublayer frame transmission on the associated interface. In particular, such an alteration has the effect of setting the transmit layer management state variable (transmitEnabled in [9]) for said interface to be true. Each alteration of an instance of this object to the value false(2) is analogous to an invocation of the disableTransmit action defined in [9] and has the effect of inhibiting MAC sublayer frame transmission on the associated interface. In particular, such an alteration has the effect of setting the transmit layer management state variable (transmitEnabled in [9]) for said interface to be false. Any transmissions in progress are completed before transmission is inhibited.
GAU dot3TestTdrValue	1.3.6.1.2.1.10.7.1.1.6	Gauge	read-only	The number of 10 MHz ticks which elapsed between the beginning of a TDR measurement and the collision which ended it, for the most recently executed TDR test. If no TDR test has been executed, or the last TDR value is not available, this object has the value 0.
dot3StatsTable	1.3.6.1.2.1.10.7.2		not-accessible	Statistics for a collection of ethernet-like interfaces attached to a particular system.
dot3StatsEntry	1.3.6.1.2.1.10.7.2.1		not-accessible	Statistics for a particular interface to an ethernet-like medium.
INT dot3StatsIndex	1.3.6.1.2.1.10.7.2.1.1	INTEGER	read-only	An index value that uniquely identifies an interface to an ethernet-like medium. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
CTR dot3StatsAlignmentErrors	1.3.6.1.2.1.10.7.2.1.2	Counter	read-only	A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check. The count represented by an instance of this object is incremented when the alignmentError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtain are, according to the conventions of [9], counted exclusively according to the error status presented to the LLC.
CTR dot3StatsFCSErrors	1.3.6.1.2.1.10.7.2.1.3	Counter	read-only	A count of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check. The count represented by an instance of this object is incremented when the frameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtain are, according to the conventions of [9], counted exclusively according to the error status presented to the LLC.
CTR dot3StatsSingleCollisionFrames	1.3.6.1.2.1.10.7.2.1.4	Counter	read-only	A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts or ifOutNUcastPkts object and is not counted by the corresponding instance of the dot3StatsMultipleCollisionFrames object.
CTR dot3StatsMultipleCollisionFrames	1.3.6.1.2.1.10.7.2.1.5	Counter	read-only	A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts or ifOutNUcastPkts object and is not counted by the corresponding instance of the dot3StatsSingleCollisionFrames object.
CTR dot3StatsSQETestErrors	1.3.6.1.2.1.10.7.2.1.6	Counter	read-only	A count of times that the SQE TEST ERROR message is generated by the PLS sublayer for a particular interface. The SQE TEST ERROR message is defined in section 7.2.2.2.4 of [12] and its generation is described in section 7.2.4.6 of the same document.
CTR dot3StatsDeferredTransmissions	1.3.6.1.2.1.10.7.2.1.7	Counter	read-only	A count of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy. The count represented by an instance of this object does not include frames involved in collisions.
CTR dot3StatsLateCollisions	1.3.6.1.2.1.10.7.2.1.8	Counter	read-only	The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a packet. Five hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mbit/s system. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.
CTR dot3StatsExcessiveCollisions	1.3.6.1.2.1.10.7.2.1.9	Counter	read-only	A count of frames for which transmission on a particular interface fails due to excessive collisions.
CTR dot3StatsInternalMacTransmitErrors	1.3.6.1.2.1.10.7.2.1.10	Counter	read-only	A count of frames for which transmission on a particular interface fails due to an internal MAC sublayer transmit error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, the dot3StatsCarrierSenseErrors object, or the dot3StatsExcessiveDeferrals object. The precise meaning of the count represented by an instance of this object is implementation- specific. In particular, an instance of this object may represent a count of transmission errors on a particular interface that are not otherwise counted.
CTR dot3StatsCarrierSenseErrors	1.3.6.1.2.1.10.7.2.1.11	Counter	read-only	The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface. The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt.
CTR dot3StatsExcessiveDeferrals	1.3.6.1.2.1.10.7.2.1.12	Counter	read-only	A count of frames for which transmission on a particular interface is deferred for an excessive period of time.
CTR dot3StatsFrameTooLongs	1.3.6.1.2.1.10.7.2.1.13	Counter	read-only	A count of frames received on a particular interface that exceed the maximum permitted frame size. The count represented by an instance of this object is incremented when the frameTooLong status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtain are, according to the conventions of [9], counted exclusively according to the error status presented to the LLC.
CTR dot3StatsInRangeLengthErrors	1.3.6.1.2.1.10.7.2.1.14	Counter	read-only	A count of frames received on a particular interface with a length field value that falls between the minimum unpadded LLC data size and the maximum allowed LLC data size inclusive and that does not match the number of LLC data octets received. The count represented by an instance of this object also includes frames for which the length field value is less than the minimum unpadded LLC data size.
CTR dot3StatsOutOfRangeLengthFields	1.3.6.1.2.1.10.7.2.1.15	Counter	read-only	A count of frames received on a particular interface for which the length field value exceeds the maximum allowed LLC data size. The count represented by an instance of this object is not incremented in implementations that observe Ethernet encapsulation conventions (by which the IEEE 802.3 length field is interpreted as the Ethernet Type field).
CTR dot3StatsInternalMacReceiveErrors	1.3.6.1.2.1.10.7.2.1.16	Counter	read-only	A count of frames for which reception on a particular interface fails due to an internal MAC sublayer receive error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsFrameTooLongs object, the dot3StatsAlignmentErrors object, the dot3StatsFCSErrors object, the dot3StatsInRangeLengthErrors object, or the dot3StatsOutOfRangeLengthFields object. The precise meaning of the count represented by an instance of this object is implementation- specific. In particular, an instance of this object may represent a count of receive errors on a particular interface that are not otherwise counted.

The value of this object for a particular interface has the same value as the ifIndex object, defined in [4,6], for the same interface.
OID ifExtnsChipSet	1.3.6.1.2.1.12.1.1.2	OBJECT IDENTIFIER	read-only	This object identifies the hardware chip set being used in the interface. The assignment of OBJECT IDENTIFIERs to various types of hardware chip sets is managed by the IANA. If the hardware chip set is unknown, the object identifier unknownChipSet OBJECT IDENTIFIER ::= { 0 0 } is returned. Note that unknownChipSet is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.
STR ifExtnsRevWare	1.3.6.1.2.1.12.1.1.3	DisplayString	read-only	An arbitrary octet string that describes the firmware version of this interface. It is intended that this should be human readable. It must only contain ASCII printable characters. Typically this will be the firmware version of the main interface software.
CTR ifExtnsMulticastsTransmittedOks	1.3.6.1.2.1.12.1.1.4	Counter	read-only	The count of frames successfully transmitted to a subnetwork or link-layer multicast destination address other than a broadcast address. For a MAC layer protocol, this includes both Group and Functional addresses.
CTR ifExtnsBroadcastsTransmittedOks	1.3.6.1.2.1.12.1.1.5	Counter	read-only	The count of frames successfully transmitted to a subnetwork or link-layer broadcast addresses. It does not include frames sent to a multicast address.
CTR ifExtnsMulticastsReceivedOks	1.3.6.1.2.1.12.1.1.6	Counter	read-only	The count of frames successfully received that are directed to an active subnetwork or link-layer multicast address (for a MAC layer protocol, this includes both Group and Functional addresses). This does not include frames directed to a broadcast address, nor frames received with errors.
CTR ifExtnsBroadcastsReceivedOks	1.3.6.1.2.1.12.1.1.7	Counter	read-only	The count of frames successfully received that are directed to a subnetwork or link-layer broadcast address. This does not include frames received with errors.
INT ifExtnsPromiscuous	1.3.6.1.2.1.12.1.1.8	INTEGER	read-only	This object has a value of false(2) if this interface only accepts packets/frames that are addressed to this station. This object has a value of true(1) when the station accepts all packets/frames transmitted on the media. The value true(1) is only legal on certain types of media. If legal, setting this object to a value of true(1) may require the interface to be reset before becoming effective.
ifExtnsRcvAddrTable	1.3.6.1.2.1.12.3		not-accessible	This table contains an entry for each address (broadcast, multicast, or uni-cast) for which the system will receive packets/ frames on a particular interface. When an interface is operating in promiscuous mode, entries are only required for those addresses for which the system would receive frames were it not operating in promiscuous mode.
ifExtnsRcvAddrEntry	1.3.6.1.2.1.12.3.1		not-accessible	A list of objects identifying an address for which the system will accept packets/ frames on a particular interface.
INT ifExtnsRcvAddrIfIndex	1.3.6.1.2.1.12.3.1.1	INTEGER	read-only	The value of ifIndex, defined in [4,6], of an interface which recognizes this entry's address.
OCT ifExtnsRcvAddress	1.3.6.1.2.1.12.3.1.2	OCTET STRING	read-only	An address for which the system will accept packets/frames on this entry's interface.
INT ifExtnsRcvAddrStatus	1.3.6.1.2.1.12.3.1.3	INTEGER	read-write	This object has the value nonVolatile(4) for those entries in the table which are valid and will not be deleted by the next restart of the managed system. Entries having the value volatile(3) are valid and exist, but have not been saved, so that will not exist after the next restart of the managed system. Entries having the value other(1) are valid and exist but are not classified as to whether they will continue to exist after the next restart. Entries having the value invalid(2) are invalid and do not represent an address for which an interface accepts frames. Setting an object instance to one of the values other(1), volatile(3), or nonVolatile(4) causes the corresponding entry to exist or continue to exist, and to take on the respective status as regards the next restart of the managed system. Setting an object instance to the value invalid(2) causes the corresponding entry to become invalid or cease to exist. It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant ifExtnsRcvAddrStatus object instance.
