Description of this pattern

PRBS pattern generation status and configuration

List of ports that can generate a PRBS bitstream.

An individual port's PRBS pattern generation status and configuration

The Mib2 ifIndex of this pattern generator port.

Bitmask indicating which patterns can be generated from this port. Bits 0 and 1 are reserved. Subsequent bits refer to the nbsPrbsPatternTable. Bit 2 corresponds to nbsPrbsPatternIndex 2, bit 3 to nbsPrbsPatternIndex 3, and so on. A bit is set (1) if that pattern can be generated by this port, cleared (0) otherwise. OCTET STRING bitmasks count the leftmost bit (MSB) as 0. A zero length OCTET STRING indicates that this object is not supported.

The nbsPrbsPatternIndex to utilize. When read, the value -1 indicates pattern generation is not supported. When read, the value 1 indicates there is no pattern currently selected. Values less than 2 cannot be written.

The maximum length of time, in seconds, that a bitstream can be generated from this port. The value 0 indicates there is no limit on the length of time. The value -1 indicates the duration cannot be set, either because generation is not supported, or because there is no way to limit the duration. The generator will not stop without user intervention. It may also indicate there is no valid protocol currently selected, so the maximum duration cannot be calculated.

The length of time, in seconds, to generate a bitstream. The value 0 indicates test should run until terminated manually by user. When read, the value -1 indicates setting a duration is not supported. Values less than 0 cannot be written.

Used to initiate and terminate pattern generation from this port. If pattern generation is not available from this port, Agent will report notSupported(1). Any SET attempts will be rejected. To generate a bitstream, user should SET this object to start(3). To terminate a bitstream, user should SET this object to stop(2). When read, Agent should report the value last SET. Agent may report stop(2) after a system reboot, or after it halts pattern generation because the time specified in nbsPrbsGenDuration elapsed. Enumeration: 'start': 3, 'notSupported': 1, 'stop': 2.

Indicates whether this port is generating a test bitstream. If notSupported(1), this port cannot generate a test bitstream. If unknown(2), this port can generate a test bitstream but cannot report the status. If idle(3), this port is currently not generating a test bitstream. If generating(4), this port currently is generating a test bitstream. Enumeration: 'unknown': 2, 'idle': 3, 'notSupported': 1, 'generating': 4.

Indicates how long, in seconds, the port has been generating a bitstream. When nbsPrbsGenStatus changes to generating(4), this.counter should be cleared to zero(0) and then increment once each second. When nbsPrbsGenStatus changes to idle(3), this.counter should be frozen at its then current value.

PRBS pattern checking status and configuration

List of ports that can check a PRBS bitstream.

An individual port's PRBS pattern checking status and configuration

The Mib2 ifIndex of this pattern checker port.

Bitmask indicating which patterns can be checked from this port. Bits 0 and 1 are reserved. Subsequent bits refer to the nbsPrbsPatternTable. Bit 2 corresponds to nbsPrbsPatternIndex 2, bit 3 to nbsPrbsPatternIndex 3, and so on. A bit is set (1) if that pattern can be generated by this port, cleared (0) otherwise. OCTET STRING bitmasks count the leftmost bit (MSB) as 0. A zero length OCTET STRING indicates that this object is not supported.

The nbsPrbsPatternIndex to check for. When read, the value -1 indicates pattern checking is not supported. When read, the value 1 indicates there is no pattern currently selected. Values less than 2 cannot be written.

The maximum length of time, in seconds, that a bitstream can be checked from this port. The value 0 indicates there is no limit on the length of time. The value -1 indicates the duration cannot be set, either because checking is not supported, or because there is no way to limit the duration. The checker will not stop without user intervention. It may also indicate there is no valid protocol currently selected, so the maximum duration cannot be calculated.

The length of time, in seconds, to check a bitstream. The value 0 indicates test should run until terminated manually by user. When read, the value -1 indicates setting a duration is not supported. Values less than 0 cannot be written.

Used to initiate and terminate pattern checking from this port. If pattern checking is not available from this port, Agent will report notSupported(1). Any SET attempts will be rejected. To check a bitstream, user should SET this object to start(3). To terminate checking, user should SET this object to stop(2). When read, Agent should report the value last SET. Agent may report stop(2) after a system reboot, or after it halts pattern checking because the time specified in nbsPrbsCheckDuration elapsed. Enumeration: 'start': 3, 'notSupported': 1, 'stop': 2.

Indicates whether this port is checking a bitstream. If notSupported(1), this port cannot check a test bitstream. If idle(2), this port is currently not checking a test bitstream. If syncIn(3), this port currently is checking a bitstream and is synchronized with the pattern specified in nbsPrbsCheckPatternIndex. If syncOut(4), this port currently is checking a bitstream and is out of synchronization with the pattern specified in nbsPrbsCheckPatternIndex. If error(5), this port currently is checking a bitstream and an unspecified error occured in the checker. If errOverflow(6), the Error Counter reached its maximum and checking has been suspended. To clear this condition, user should set nbsPrbsCheckAction to stop(2). If gaveUp(7), the pattern checker was unable to synchronize and aborted. Enumeration: 'syncOut': 4, 'errOverflow': 6, 'idle': 2, 'error': 5, 'gaveUp': 7, 'notSupported': 1, 'syncIn': 3.

Indicates how long, in seconds, the port has been checking a bitstream. When nbsPrbsCheckStatus changes to idle(2), this.counter should be cleared to zero(0) and then increment once each second. When nbsPrbsCheckStatus changes to syncIn(3) or syncOut(4), this.counter should be frozen at its then current value.

Indicates how many errors were detected during the last pattern checking session. The Agent should clear this counter to zero(0) when nbsPrbsCheckStatus changes from idle(2). While pattern checking, Agent may increase this counter as errors occur. Once nbsPrbsCheckStatus changes to idle(2), this counter should report the final error count. If errors were detected but the count is unknown, Agent should report the number 1.

Indicates how frequently, in minutes, the nbsPrbsTrapCheckerStatusUpdate Notification should be sent. The value zero (0) disables update Notifications.

Objects used as varbinds in traps

PRBS event notifications

Sent when nbsPrbsGenStatus transitions to generating(4). This Notification should be of Severity INFO.

Sent when nbsPrbsGenStatus transitions from generating(4). This Notification should be of Severity INFO.

Sent when an interface begins checking for a bitstream. This Notification should be of Severity INFO.

Sent when an interface stops checking for a bitstream. This Notification should be of Severity INFO.

Sent when nbsPrbsCheckStatus transitions to errOverflow(6). This event indicates that the checker was unable to continue and is now in a suspended state which requires a user to manually stop the checker. This Notification should be of Severity ERROR.

Sent when nbsPrbsCheckErrors transitions from zero (0). This event indicates the first error was detected in the incoming bitstream. This Notification should be of Severity ERROR.

This Notification periodically reports the status, error counts, and running time of the Checker process. This Notification should be of Severity INFO.

Sent when a checker port synchronizes with a bitstream. This Notification should be of Severity ERROR.

Sent when a checker port loses synchronization with a bitstream. This Notification should be of Severity ERROR.
