Protocol Tabs

Power Low
Threshold Sets the received optical power level (in dBm) threshold. If
the power drops below the threshold, the
Power Low alarm is
triggered. This applies to all optical channels supported by
the CFP.
The threshold range is from 0 to -100 dBm ppm, in
increments of 0.1. (-100 dBm is disabled.)
Out of Frequency
Threshold Sets the frequency threshold (in ppm) for the Line Frequency
Offset. When the threshold is reached, the Frequency Wide
alarm is triggered. This applies to all physical channels
supported by the CFP8.
The threshold range is from 0 to 300 ppm, in increments of
0.1. (0 ppm is disabled.)
Excessive Skew
Threshold Sets the Skew alarm (Bit Delay) threshold (in bits) for all
virtual lanes (Logic/FEC/PCS) .
When a virtual lane's measured Skew (Bit delay) exceeds the
configured threshold, the Skew alarm for that virtual lane is
triggered.
The threshold range is from 0 to the maximum Bit delay (in
bits), in increments of 1. (0 bits is disabled.)
SER Degrade
Interval
Sets the measurement period for the SER Degraded Interval
used to trigger FEC Degraded SER alarms, in Codewords
from 0 to 65535 codewords. (MPM-400G card only)
For 400GE, 1 codeword equals 256ns.
If the value of this setting is set to 0 (which is Disabled),
then the FEC Degraded SER alarm feature is Disabled.
