[c-nsp] %SFF8472-5-THRESHOLD_VIOLATION: Te0/2: Rx power low warning; Operating value: -12.5 dBm, Threshold value -9.9 dBm

[Muhammad Jawwad Paracha]

Hi Farooq

Trying changing fiber cable. This error is normally generated when signal
loss level exceeds the operating value For e.g. if point A sends a signal of
2 dbm, when it reaches point B signal is -12.5dBm("show interface tengig0/x
trans detail" output will give you details) i.e. loss of 10.5 dbm. Warning
threshold value in this case is -9.9 dBm and Operating threshold would be
around -13dBm. If this signal is less then -13dBm, Tengig port would go into
errdisabled mode(if error recovery is not configured). Signal loss needs to
be controlled here.

Hope it helps
