fec — The FEC corrected bit errors are used to declare the presence of the Signal Fail and Signal
sf-threshold
Syntax sf-threshold threshold
Context config>port>otu>sf-threshold
Description
This command specifies the error rate at which to declare the signal fail condition for the the signal
fail (SF) threshold. The value represents an error rate of 10E-<value>.
The SF threshold must:
Default
4
Parameters threshold — Specifies the signal fail (SF) threshold.
sd-threshold
Syntax sd-threshold threshold
Context config>port>otu>sd-threshold
Description
This command specifies the error rate at which to declare the signal fail condition for the signal
degrade (SD). The value represents an error rate of 10E-value.
The SD threshold must::
Default
7
Parameters threshold — Specifies the exponent of the error rate, thus an error rate from 10E-3 to 10E-7.
sm-tti
Syntax sm-tti
Context config>port>otu
Description
This command enables the context to configure section monitoring trail trace identifier parameters.
