sf-sd-method
Syntax sf-sd-method {bip8 | fec}
Context config>port>otu>sf-sd-method
Description
This command specifies the method used to determine the signal fail and signal degrade alarms. When select
the bip8 method is selected, the SM-BIP8 errors are used. When the FEC method is selected, the FEC cor-
rected bits are used.
The following rules must be followed:
•
•
•
Default fec
Parameters bip8 — The SM-BIP8 errors are used to declare the presence of the Signal Fail and Signal Degrade condi-
tion.
fec — The FEC corrected bit errors are used to declare the presence of the Signal Fail and Signal Degrade
condition.
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.
Values
sd-threshold
Syntax sd-threshold threshold
Context config>port>otu>sd-threshold
7750 SR Interface Configuration Guide
The port's OTU must be enabled to set or change the sf-sd-method.
The FEC mode must be enhanced or g709 before setting the sf-sd-method to fec.
The SF threshold must be 5 or higher before setting the sf-sd-method to bip8.
Be less than the SD threshold.
Be 5 or higher before setting the sf-sd-method to bip8.
