This attribute group contains operational attributes of a bus tap. This information outlines what the bus tap is doing and why it is doing it, and is primarily intended for use in diagnosing the cause of a bus- related problem reported by the module.

An entry in the mscShelfCardBusTapOperTable.

This attribute records the hardware problems that prevent the bus tap from using the associated bus. It may contain any combination of the following values. selfTest: the bus tap has failed its self-test clockSignal: the bus tap is not receiving clock signals from the bus parityError: the bus tap has detected too many parity errors on the bus Description of bits: selfTest(0) clockSignal(1) parityError(2)

This attribute records the non-hardware problems that prevent the bus tap from using the associated bus. It may contain any combination of the following values. busLocked: the bus is locked busDisabled: the bus is disabled Description of bits: busLocked(0) busDisabled(1)

This attribute records the slot numbers of the cards that the bus tap considers available on the busthat is, the cards that have an operational bus tap connected to the bus. The value of this attribute is determined automatically by the bus tap by monitoring signals generated by each bus tap on the bus; it cannot be changed by the operator. Normally, every card in the module signals its availability on both buses; if a card does not signal its availability on a bus this indicates that the card is not present or that its bus tap has failed. By examining this attribute for both of a card's BusTap components, it is possible to determine which cards are present in the module and which buses each can use. Note: If failuresInEffect contains either selfTest or clockSignal the bus tap is unable to monitor the availability of the bus taps on the bus; cardsAvailable will indicate that no bus taps are available on the bus. Description of bits: n0(0) n1(1) n2(2) n3(3) n4(4) n5(5) n6(6) n7(7) n8(8) n9(9) n10(10) n11(11) n12(12) n13(13) n14(14) n15(15)

This attribute records the slot numbers of the cards which the bus tap is currently configured to transmit cells to. This configuration is managed automatically, and cannot be changed by the operator. By examining this attribute for both of a card's BusTap components, it is possible to determine which bus (if any) the card uses when it needs to transmits cells to a specific card in the module. Description of bits: n0(0) n1(1) n2(2) n3(3) n4(4) n5(5) n6(6) n7(7) n8(8) n9(9) n10(10) n11(11) n12(12) n13(13) n14(14) n15(15)

This attribute group records errors that the bus tap has detected since the card was last rebooted. This information is intended for use in detecting and diagnosing bus-related problems within a module.

An entry in the mscShelfCardBusTapErrorsTable.

This attribute records the error code generated by the most recent self-test of the bus tap. The value zero indicates that the self-test was successful. A non-zero value indicates that the self-test failed, and is used by the service technician when a defective card is returned for repair.

This attribute records the number of times that the bus tap has detected a loss of the fundamental clock signal used by the bus. Each occurrence may result in the loss of one or more cells or frames. This type of event may occur during normal operation of the module, for example when switching from one of the bus's clock sources to the other; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap has detected a loss of the end-of-cell timing signal used by the bus. Each occurrence may result in the loss of one or more cells or frames. This type of event may occur during normal operation of the module, for example switching the bus's clock source from one card to another; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap has detected a cell with invalid parity on the bus. Each occurrence may result in the loss of one or more cells or frames. This type of event may occur during normal operation of the module, for example when a card is inserted, removed, or reboots; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap was unable to receive a frame from the bus because all of its bus receive channels were in use. Each occurrence results in the loss of the frame. This type of event may occur during normal operation of the module, for example when the module is operating in single bus mode; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap was unable to receive a frame from the bus because it did not receive the last cell of the frame before the first cell of the following frame from the same source. Each occurrence results in the loss of both frames. This type of event may occur during normal operation of the module, for example when a card reboots; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap was unable to receive a frame from the bus because the delay between two successive cells in that frame exceeded the maximum allowable duration. Each occurrence results in the loss of the frame. This type of event may occur during normal operation of the module, for example when the module changes bus mode; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap was unable to receive a frame from the bus because it was destined for a bus transmit queue; that is, the frame would have been immediately retransmitted over a bus. Each occurrence results in the loss of the frame. This type of event should never occur during normal operation of the module and indicates the occurrence of a hardware or software fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

This attribute records the number of times that the bus tap was unable to receive a frame from the bus because it required more than 255 blocks of shared memory. Each occurrence results in the loss of the frame. This type of event should never occur during normal operation of the module and indicates improper configuration of the card or the occurrence of a hardware or software fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

It can be set to one of the following values: ok: all operational cards can receive signals from the clock source. failed: at least one operational card is unable to receive signals from the clock source. unknown: status of a clock source is unknown. To determine the status of the clock source, a test must be run. testInProgress: the clock source is currently being tested. notApplicable: the LP state of the clock source's card is down or not provisioned.

This variable represents the mscShelfBusClockSourceStatusTable specific index for the mscShelfBusClockSourceStatusTable. Enumeration: 'alternate': 1, 'activeCP': 0.

This variable represents an individual value for the mscShelfBusClockSourceStatusTable. Enumeration: 'failed': 1, 'testInProgress': 3, 'notApplicable': 4, 'ok': 0, 'unknown': 2.

This entry controls the addition and deletion of mscShelfTest components.

A single entry in the table represents a single mscShelfTest component.

This variable is used as the basis for SNMP naming of mscShelfTest components. These components cannot be added nor deleted.

This variable provides the component's string name for use with the ASCII Console Interface

This variable represents the storage type value for the mscShelfTest tables.

This variable represents the index for the mscShelfTest tables.

This group contains provisionable attributes of the Test component.

An entry in the mscShelfTestProvTable.

This attribute specifies whether or not a bus clock source test is automatically executed after a clock source's LP state changes, and after failure or recovery of the active CP bus clock source. Since tests of an alternate bus clock source may cause a minor loss of traffic, the attribute is set to disabled by default. If set to enabled, a bus clock source test is automatically executed. If the status of the corresponding Shelf Bus clockSourceStatus is changed after the test, an alarm is issued if the status is one of the following: ok, failed, or unknown. If set to disabled, no bus clock source test is automatically executed. However, a test can be executed by the RUN command. If the status is changed after the test, an alarm is issued if the status is one of the following: ok, or failed. Enumeration: 'disabled': 1, 'enabled': 0.

This attribute group contains the attributes that govern the operation of a shelf test.

An entry in the mscShelfTestSetupTable.

type The attribute determines the test to be executed when the RUN command is applied to the component. Note that running a busClock test may cause a minor loss of traffic. Enumeration: 'busClock': 0.

This attribute group contains the results of the Shelf Test that is currently running; if no test is running, the attribute group contains the results of the most recently completed Shelf Test. The attributes of the Results group are reset to their initial values whenever a corresponding Shelf Test is run or the corresponding attribute of the Setup group is set.

An entry in the mscShelfTestResultsTable.

busClockTestResult This attribute records the result of the bus clock manual test. The result can be one of the following values. pass : the test passed fail : the test failed noTest : the test was not executed when RUN command is issued, because the shelf was in single bus mode. Enumeration: 'fail': 1, 'pass': 2, 'noTest': 0.
