QUERY PERFORMANCE SFE
This command displays the performance data for Short Failure Event. A Short
Failure Event (SFE) is a Failure Event lasting less than two minutes. A Failure
Event begins with either 10 Severely Errored Seconds or three or more seconds of
continuous loss of signal integrity (LOS, high BER, or AIS condition) and ends at
the beginning of a 10 Severely Errored Second-free period.
During the power-up cycle, the entire performance database is cleared and data
collection starts over.
Display Formats
The display format for the EFS, SES, and SFE is shown in Example A.
Figure 4-1 Example A
The display format for the ES only is shown in Example B.
Figure 4-2 Example B
The following definitions for x, y, z, and m are valid for Example A and Example B.
x is the total valid intervals collected in the performance monitoring history
database. The maximum number for x is 96.
y is the total number of seconds in the current 15-minute interval. The maximum
number for y is 900.
z is the total accumulated performance monitoring number in the last 24 hours, not
including the current interval. (For Error Free Seconds, this is the total percentage
of the Error Free Seconds in the last 24 hours.)
m is the total accumulated performance monitoring number in the current
15-minute interval. (For Error Free Seconds, this is the total percentage of the
Error Free Seconds in the current 15-minute interval.)
