What Is Nortel-MsCarrier-MscPassport-ApsMIB?
Nortel-MsCarrier-MscPassport-ApsMIB provides SNMP objects for Automatic Protection Switching (APS) configuration on SONET links of Nortel MsCarrier MscPassport switches, the mechanism that automatically fails traffic over from a working SONET line to a protect line on failure. It defines row status/provisioning tables for each APS component, a customer-identifier data table, and a test sub-component used to exercise or verify protection-switch behavior. Because APS status directly reflects whether a SONET line has failed over to its protect path, this MIB is a key hardware fault-monitoring tool: polling it shows whether a protection switch has occurred, which is a direct indicator of a physical line fault on the working SONET interface. It depends on SONET/APS standards (e.g., Telcordia GR-253/ITU-T G.783 protection-switching concepts) for its semantics, layered on the Passport RowStatus/StorageType conventions. It is used on Nortel MsCarrier MscPassport switches carrying SONET transport in carrier backbone networks requiring high-availability line protection, as modeled by the Nortel-MsCarrier-MscPassport-ApsMIB MIB.
IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-ApsMIB. 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.
Supported Devices
- Nortel MsCarrier MscPassport switch (SONET/APS)
Monitoring Examples
An operator polls mscApsRowStatusTable and mscApsProvTable to confirm an APS component is provisioned and active on a SONET line pair, then checks whether a protection switch has occurred by examining the component's state, which would indicate the working line failed and traffic moved to the protect line. Running mscApsTest exercises the protection-switching mechanism to verify it will fail over correctly before a real fault occurs. mscApsCidDataTable's mscApsCustomerIdentifier identifies which customer's circuits are riding on the protected SONET pair.
What Can Be Monitored
- APS component/protection-switch status
- customer identifier mapping
- protection test results
- component storage type

| U32 mscApsCustomerIdentifier | 1.3.6.1.4.1.562.36.2.1.134.10.1.1 | Unsigned32 | read-write | This attribute holds the Customer Identifier (CID). Every component has a CID. If a component has a cid attribute, the component's CID is the provisioned value of that attribute; otherwise the component inherits the CID of its parent. The top- level component has a CID of 0. Every operator session also has a CID, which is the CID provisioned for the operator's user ID. An operator will see only the stream data for components having a matching CID. Also, the operator will be allowed to issue commands for only those components which have a matching CID. An operator CID of 0 is used to identify the Network Manager (referred to as 'NetMan' in DPN). This CID matches the CID of any component. Values 1 to 8191 inclusive (equivalent to 'basic CIDs' in DPN) may be assigned to specific customers. |
| INT mscApsFarEndRequest | 1.3.6.1.4.1.562.36.2.1.134.13.1.4 | INTEGER | read-only | This attribute indicates the request currently being received from the far end in the SONET/SDH line overhead K1 byte of the protection line. Requests are prioritized so that high priority requests preempt or block those with a lower priority. The possible requests, in order of priority from highest to lowest, are as follows. lockoutOfProtection the working line is prevented from switching to the protection line under any circumstances due to an ProtectionLockout command being in effect. forcedSwitch the line indicated by attribute nearEndRequestChannel has a Switch -force command in effect against it. Note that a signalFail on the protection line has higher priority than a forcedSwitch. signalFail the line indicated by attribute nearEndRequestChannel is experiencing a signal failure (SF). Failures include LOS, LOF, received AIS-L, a signal BER exceeding 10-3, LOP, received AIS-P, LCD, or a locked Sonet, Sdh, or Path component. Note that a signalFail on the protection line has higher priority than a forcedSwitch. signalDegrade the line indicated by attribute nearEndRequestChannel is experiencing a signal degradation (SD). For more information on the conditions required to declare and clear an SD please refer to the desription for attribute signalDegradeRatio. A such that the signal BER exceeds the value provisioned in the signalDegradeRatio attribute, or is still exceeding manualSwitch the line indicated by attribute nearEndRequestChannel has a Switch command in effect against it. waitToRestore the protection line is active, provisioned attribute revertive is yes, and the working line has recovered from a Signal Fail or Signal Degrade. After the period defined by attribute waitToRestorePeriod the working line will automatically revert to being the receive active line and the request will change to noRequest. reverseRequest the line indicated by attribute nearEndRequestChannel is active due to a request from the far end. This request is only applicable when the provisioned mode is bidirectional. doNotRevert the protection line is active, provisioned attribute revertive is no, and either: (1) the working line has recovered from a signalFail or signalDegrade; or (2) a forcedSwitch or manualSwitch request has been cleared. The receive active line will not automatically revert to the working line. noRequest the working line is active and no other requests are in effect. DESCRIPTION |
| INT mscApsFarEndRequestChannel | 1.3.6.1.4.1.562.36.2.1.134.13.1.5 | INTEGER | read-only | This attribute indicates to which channel the farEndRequest applies. |
| NUM mscApsHoldOffTime | 1.3.6.1.4.1.562.36.2.1.134.11.1.6 | FixedPoint1 | read-write | The hold off time is the delay between the detection of a Signal Fail or Signal Degrade on the active line and the initiation of a switchover. |
| I32 mscApsIndex | 1.3.6.1.4.1.562.36.2.1.134.1.1.10 | Integer32 | not-accessible | This variable represents the index for the mscAps tables. |
| INT mscApsMode | 1.3.6.1.4.1.562.36.2.1.134.11.1.4 | INTEGER | read-write | This attribute specifies the protection mode to use. It has possible values of unidirectional and bidirectional. The unidirectional mode allows the Aps to decide independently of the far end which channel, either working or protection, will be active for receive. The bidirectional mode instructs the Aps to decide jointly with the far end which channel, either working or protection, will be active for receive. Note that while an Aps Test is being run the Aps will operate in unidirectional mode, regardless of the actual provisioned mode. |
| INT mscApsModeMismatchAlarm | 1.3.6.1.4.1.562.36.2.1.134.13.1.10 | INTEGER | read-only | This attribute indicates whether the Aps component is experiencing an APS mode mismatch alarm (code 7011 5272). This alarm indicates either: (1) that the far end is operating with a 1:n switching architecture (not supported by Passport), as opposed to 1+1; or (2) that the far end's provisioned mode is not the same as the nears end's provisioned mode. When a mode mismatch occurs: (1) if the far end is operating with a 1:n switching architecture it will operate as 1+1; and (2) if either end has a provisioned mode of unidirectional then both ends will operate unidirectionally. |
| INT mscApsNearEndRequest | 1.3.6.1.4.1.562.36.2.1.134.13.1.2 | INTEGER | read-only | This attribute indicates the request currently being transmitted to the far end in the SONET/SDH line overhead K1 byte of the protection line. Requests are prioritized so that high priority requests preempt or block those with a lower priority. The possible requests, in order of priority from highest to lowest, are as follows. lockoutOfProtection the working line is prevented from switching to the protection line under any circumstances due to an ProtectionLockout command being in effect. forcedSwitch the line indicated by attribute nearEndRequestChannel has a Switch -force command in effect against it. Note that a signalFail on the protection line has higher priority than a forcedSwitch. signalFail the line indicated by attribute nearEndRequestChannel is experiencing a signal failure (SF). Failures include LOS, LOF, received AIS-L, a signal BER exceeding 10-3, LOP, received AIS-P, LCD, or a locked Sonet, Sdh, or Path component. Note that a signalFail on the protection line has higher priority than a forcedSwitch. signalDegrade the line indicated by attribute nearEndRequestChannel is experiencing a signal degradation (SD). For more information on the conditions required to declare and clear an SD please refer to the desription for attribute signalDegradeRatio. A such that the signal BER exceeds the value provisioned in the signalDegradeRatio attribute, or is still exceeding manualSwitch the line indicated by attribute nearEndRequestChannel has a Switch command in effect against it. waitToRestore the protection line is active, provisioned attribute revertive is yes, and the working line has recovered from a Signal Fail or Signal Degrade. After the period defined by attribute waitToRestorePeriod the working line will automatically revert to being the receive active line and the request will change to noRequest. reverseRequest the line indicated by attribute nearEndRequestChannel is active due to a request from the far end. This request is only applicable when the provisioned mode is bidirectional. doNotRevert the protection line is active, provisioned attribute revertive is no, and either: (1) the working line has recovered from a signalFail or signalDegrade; or (2) a forcedSwitch or manualSwitch request has been cleared. The receive active line will not automatically revert to the working line. noRequest the working line is active and no other requests are in effect. |
| INT mscApsNearEndRequestChannel | 1.3.6.1.4.1.562.36.2.1.134.13.1.3 | INTEGER | read-only | This attribute indicates to which channel the nearEndRequest applies. |
| INT mscApsNearEndRxActiveLine | 1.3.6.1.4.1.562.36.2.1.134.13.1.1 | INTEGER | read-only | This attribute indicates which near end line is active for receiving data from the far end. |
| INT mscApsOperationalState | 1.3.6.1.4.1.562.36.2.1.134.12.1.2 | INTEGER | read-only | This attribute indicates the OSI Operational State of the component. The value enabled indicates that the component is available for operation. Note that if adminState is locked, it would still not be providing service. The value disabled indicates that the component is not available for operation. For example, something is wrong with the component itself, or with another component on which this one depends. If the value is disabled, the usageState must be idle. The OSI Status attributes, if supported by the component, may provide more details, qualifying the state of the component. |
| mscApsOperEntry | 1.3.6.1.4.1.562.36.2.1.134.13.1 | not-accessible | An entry in the mscApsOperTable. | |

| OCT mscApsProceduralStatus | 1.3.6.1.4.1.562.36.2.1.134.12.1.5 | OCTET STRING | read-only | If supported by the component, this attribute indicates the OSI Procedural status of the component. Note that, even though it is defined as a multi-valued set, at most one value is shown to the user. When no values are in the set, this indicates that either the attribute is not supported or that none of the status conditions described below are present. The value initializationRequired indicates (for a resource which doesn't initialize autonomously) that initialization is required before it can perform its normal functions, and this procedure has not been initiated. The operationalState is disabled. The value notInitialized indicates (for a resource which does initialize autonomously) that initialization is required before it can perform its normal functions, and this procedure has not been initiated. The operationalState may be enabled or disabled. The value initializing indicates that initialization has been initiated but is not yet complete. The operationalState may be enabled or disabled. The value reporting indicates the resource has completed some processing operation and is notifying the results. The operationalState is enabled. The value terminating indicates the component is in a termination phase. If the resource doesn't reinitialize autonomously, operationalState is disabled; otherwise it is enabled or disabled. Description of bits: initializationRequired(0) notInitialized(1) initializing(2) reporting(3) terminating(4) |
| LIN mscApsProtectionLine | 1.3.6.1.4.1.562.36.2.1.134.11.1.3 | Link | read-write | This attribute is a link to the Path component whose parent Sonet or Sdh component provides the Aps' protection line. A value must be defined for this component. This attribute is critical because the APS process runs on the LP associated with the protectionLine. The protection line must exist under the same Lp as the working line, and must link to a Path component under the same type of port component (Sonet or Sdh) as the protection line. Valid workingLine and protectionLine pairs must exist. For the 1pOC12SmLrAtm, the protectionLine must be lp/n sonet/1 path/0. For other APS compatible cards, the workingLine and protectionLine pairs must use port 0 with port 1 and port 2 with port 3. For example, if the workingLine is linked to a path on port 0, then the protectionLine must be linked to a path on port 1. Sonet APS is available on cards of type 2pOC3SmAtm2, 2pOC3MmAtm2, 4pOC3SmIrAtm, 4pOC3MmAtm, and 1pOC12SmLrAtm. |
| INT mscApsProtocolFailureAlarm | 1.3.6.1.4.1.562.36.2.1.134.13.1.9 | INTEGER | read-only | This attribute indicates whether the Aps component is experiencing an APS protocol failure alarm. Protocol failure alarms include the protection switching byte mismatch alarm (code 7011 5270) and the channel mismatch failure alarm (code 7011 5271). |
| mscApsProvEntry | 1.3.6.1.4.1.562.36.2.1.134.11.1 | not-accessible | An entry in the mscApsProvTable. | |
| mscApsProvTable | 1.3.6.1.4.1.562.36.2.1.134.11 | not-accessible | This group contains the provisioned attributes for the Aps component. | |
| INT mscApsRevertive | 1.3.6.1.4.1.562.36.2.1.134.11.1.5 | INTEGER | read-write | This attribute specifies whether revertive switching is to be used. It has possible values of no or yes. When this attribute is no, the Aps will not revert the receive active line from protection back to working when a working line request is cleared. When this attribute is yes, the Aps will revert the receive active line from protection back to working when a working line request is cleared, after the provisioned waitToRestorePeriod has expired. Note that it is acceptable for the near end and far end to be provisioned with a mix of revertive and nonrevertive switching. |
| ROW mscApsRowStatus | 1.3.6.1.4.1.562.36.2.1.134.1.1.1 | RowStatus | read-write | This variable is used as the basis for SNMP naming of mscAps components. These components can be added and deleted. |
| mscApsRowStatusEntry | 1.3.6.1.4.1.562.36.2.1.134.1.1 | not-accessible | A single entry in the table represents a single mscAps component. | |
| mscApsRowStatusTable | 1.3.6.1.4.1.562.36.2.1.134.1 | not-accessible | This entry controls the addition and deletion of mscAps components. | |
| OCT mscApsSdOnLines | 1.3.6.1.4.1.562.36.2.1.134.13.1.6 | OCTET STRING | read-only | This attribute indicates which lines (if any) are currently experiencing a Signal Degrade (SD). Description of bits: protection(0) working(1) |
| INT mscApsSignalDegradeRatio | 1.3.6.1.4.1.562.36.2.1.134.11.1.8 | INTEGER | read-write | This attribute specifies the minimum bit error ratio (BER) for which a Signal Degrade failure is declared. Its value is the exponent of the BER, with possible values of -5 through -9 inclusive, which correspond to a BER range of 10-5 through 10-9. The switch initiation time for a Signal Degrade varies depending on the observed BER (not the provisioned signalDegradeRatio), as described in the following table. Observed BER Switch Initiation Time 10-3 10 milliseconds 10-4 100 milliseconds 10-5 1 second 10-6 10 seconds 10-7 100 seconds 10-8 16 minutes 40 seconds 10-9 2 hours 46 minutes 40 seconds The clearing threshold for a Signal Degrade is one-tenth the signalDegradeRatio; for example, if the provisioned signalDegradeRatio is -5, the corresponding clearing threshold will be 10-6. The clearing time varies depending on the clearing threshold (not the observed BER), and can be determined from the above table. |
| INT mscApsStandbyStatus | 1.3.6.1.4.1.562.36.2.1.134.12.1.8 | INTEGER | read-only | If supported by the component, this attribute indicates the OSI Standby status of the component. The value notSet indicates that either the attribute is not supported or that none of the status conditions described below are present. Note that this is a non-standard value, used because the original specification indicated this attribute was set-valued and thus, did not provide a value to indicate that none of the other three are applicable. The value hotStandby indicates that the resource is not providing service but will be immediately able to take over the role of the resource to be backed up, without initialization activity, and containing the same information as the resource to be backed up. The value coldStandby indicates the resource is a backup for another resource but will not be immediately able to take over the role of the backed up resource and will require some initialization activity. The value providingService indicates that this component, as a backup resource, is currently backing up another resource. |

| INT mscApsTestAdminState | 1.3.6.1.4.1.562.36.2.1.134.2.10.1.1 | INTEGER | read-only | This attribute indicates the OSI Administrative State of the component. The value locked indicates that the component is administratively prohibited from providing services for its users. A Lock or Lock - force command has been previously issued for this component. When the value is locked, the value of usageState must be idle. The value shuttingDown indicates that the component is administratively permitted to provide service to its existing users only. A Lock command was issued against the component and it is in the process of shutting down. The value unlocked indicates that the component is administratively permitted to provide services for its users. To enter this state, issue an Unlock command to this component. |
| STR mscApsTestBitErrorRate | 1.3.6.1.4.1.562.36.2.1.134.2.12.1.11 | AsciiString | read-only | This attribute is not displayed for ATM cards because the physical layer drops all errored frames at the controller interface. For all other card types, this attribute is the calculated bit error rate on the link. Test data are generated and sent in frames of a preset size (frameSize). The Test component will try to estimate the number of bit errors in any errored frame which is identifiable. The statistics will be updated accordingly. A lost frame (may be due to an error on the flag sequence) will be discarded for the bit error rate calculation. The result is presented in the form of xEsyy, where x is the mantissa, syy is the exponent, for example 0E+00, 2E-09. Note that the bitErrorRate is an estimate only. For more reliable test results, the test should be done over a long period. Multiple tests would also improve the confidence level of the test results. |
| NUM mscApsTestBitsRx | 1.3.6.1.4.1.562.36.2.1.134.2.12.1.7 | PassportCounter64 | read-only | This attribute is the total number of bits received during the test period. This counter is not expected to reach its maximum value. The counter will wrap around to 0 if it does reach the maximum value. |
| NUM mscApsTestBitsTx | 1.3.6.1.4.1.562.36.2.1.134.2.12.1.4 | PassportCounter64 | read-only | This attribute is the total number of bits sent during the test period. As long as the line speed of the hardware interface is less than 70 Mbit/s, this counter is not expected to reach the maximum value. |
| NUM mscApsTestBytesRx | 1.3.6.1.4.1.562.36.2.1.134.2.12.1.8 | PassportCounter64 | read-only | This attribute is the total number of bytes received during the test period. This counter is not expected to reach its maximum value. The counter will wrap around to 0 if it does reach its maximum value. |

| INT mscApsTestCauseOfTermination | 1.3.6.1.4.1.562.36.2.1.134.2.12.1.3 | INTEGER | read-only | This attribute indicates either the status of the test or the cause of the test's termination: neverStarted indicates that the test has not yet been started. testRunning indicates that the test has been started. stoppedByOperator indicates that the operator issued a stop command on a test that was running. testTimeExpired indicates that the test ran for the time specified by the test's duration. loopCodeSyncFailed indicates that the local end failed to synchronize to the loopCode pattern. The local end transmits the loopCode pattern to cause the remote end to apply a loopback, after which the local end should receive the loopCode pattern. The exact pattern used to request loopCode depends on the test type. This failure indicates a high rate of transmission errors, or that the remote end has failed to apply the loopback. patternSyncFailed indicates that the local end failed to synchronize to the frmPatternType test pattern, that should have been looped back at the remote end. This failure indicates a high rate of transmission errors or the absence of a loopback. patternSyncLost indicates that the local end gained and then lost synchronization to the returned frmPatternType test pattern. This failure indicates a sudden increase in transmission errors, frame slippage, or the removal of an existing loopback. unknown is set when a reason to terminate other than those listed here is encountered. Note: Only MSA cards support recognition of the failures loopCodeSyncFailed, patternSyncFailed and patternSyncLost. Other cards will not terminate the test under the conditions described by these values. |

| LIN mscApsWorkingLine | 1.3.6.1.4.1.562.36.2.1.134.11.1.2 | Link | read-write | This attribute is a link to the Path component whose parent Sonet or Sdh component provides the Aps' working line. A value must be defined for this component. The working line must exist under the same Lp as the protection line and must link to a Path component under the same type of port component (Sonet or Sdh) as the protection line. Valid workingLine and protectionLine pairs must exist. For the 1pOC12SmLrAtm card, the workingLine must be lp/n sonet/0 path/ 0. For other APS compatible cards, the workingLine and protectionLine pairs must use port 0 with port 1 and port 2 with port 3. For example, if the workingLine is linked to a path on port 0, then the protectionLine must be linked to a path on port 1. Sonet APS is available on cards of type 2pOC3SmAtm2, 2pOC3MmAtm2, 4pOC3SmIrAtm, 4pOC3MmAtm, and 1pOC12SmLrAtm. |
