This read-only MIB object returns the aggregate link-error monitor error count, set to 0 only on station initialization.
This read-write MIB object contains the link error rate estimate at which a link connection is be broken. It ranges from 10**-4 to 10**-15 and is reported as the absolute value of the base-10 logarithm (default of 7).
Valid Values: | 4 to 15 |
Default Value: | 7 |
This read-write MIB object contains the link error rate estimate at which a link connection generates an alarm. It ranges from 10**-4 to 10**-15 and is reported as the absolute value of the base-10 logarithm of the estimate (default of 8).
Valid Values: | 4 to 15 |
Default Value: | 8 |
This read-only MIB object displays an indication of the connect state of this PORT and is equal to the value of Connect_State (see ANSI 9.4.1).
Valid Values: | disabled | (1) |
connecting | (2) | |
standby | (3) | |
active | (4) |
This read-only MIB object displays the state of this port's PCM state machine (see ANSI SMT 9.6.2).
Valid Values: | pc0 | (1) Off |
| pc1 | (2) Break |
| pc2 | (3) Trace |
| pc3 | (4) Connect |
| pc4 | (5) Next |
| pc5 | (6) Signal |
| pc6 | (7) Join |
| pc7 | (8) Verify |
| pc8 | (9) Active |
| pc9 | (10) Maint |
This read-only MIB object displays the value of PC_Withhold (see ANSI SMT 9.4.1).
Valid Values: | none | (1) |
This read-only MIB object condition becomes active when the value of fddiPORTLerEstimate is less than or equal to fddiPORTLerAlarm. This is reported with the Status Report Frames (SRF) (refer to ANSI SMT 7.2.7 and 8.3).
Valid Values: | false | (2) |
This read-only MIB object variable indicates the presence of underlying hardware support for this port object. If the value of this object is false, the reporting of the objects in this entry can be handled in an implementation-specific manner.
Valid Values: | true | (1) |
This read-write MIB object causes a control signal to be generated with a control_action of Signal and the variable parameter set with the appropriate value (that is, PC_Maint, PC_Enable, PC_Disable, PC_Start, or PC_Stop). Refer to ANSI 9.4.2 for more information.
Valid Values: | other | (1) |
maintPORT | (2) | |
enablePORT | (3) | |
disablePORT | (4) | |
startPORT | (5) | |
stopPORT | (6) | |
Default Value: | other | (1) |
