Interfaces
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.
Values
sm-tti
Syntax sm-tti
Context config>port>otu
Description This command enables the context to configure section monitoring trail trace identifier parameters.
expected
Syntax expected {string string | bytes byte-sequence | auto-generated | use-rx}
Context config>port>otu>sm-tti
Description This command enables the user to configure the expected RX Trail Trace Identifier (TTI) for Section Moni-
toring (SM) in the OTU overhead. This identifier can be a string or a non-printable sequence of bytes. The
length of the string or sequence of bytes cannot exceed 64 bytes. This trace should match the expected far-
end port's SM trace. When this trace does not match the received SM trace, the OTU-TIM alarm will be
reported if enabled.
Default Blank (all zeros)
Parameters auto-generated — Sets the default
string string — Sets the SM TTI to the string provided by the user. If the string is less than 64 bytes, the
remaining bytes will be set to 0.
bytes — [byte1 byte2 ... byte64]. Sets the SM TTI to the sequence of bytes provided by the user. If the user
provides less than 64 bytes, the remaining bytes will be set to 0.
use-rx — Copies the received sm-tti to the expected either as a string or a sequence of bytes depending on
the received sm-tti data.

Be greater than the SF threshold.
Be 5 or higher before setting the sf-sd-method to bip8.
