Dear Jawwad Pls find attached output of 'show int trans'
Date: Mon, 24 Jan 2011 15:12:44 +0500 Subject: Re: [c-nsp] %SFF8472-5-THRESHOLD_VIOLATION: Te0/2: Rx power low warning; Operating value: -12.5 dBm, Threshold value -9.9 dBm From: jawwa...@gmail.com To: farooq_...@hotmail.com CC: cisco-nsp@puck.nether.net 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 Regards Jawwad Paracha IBM On Mon, Jan 24, 2011 at 3:03 PM, Farooq Razzaque <farooq_...@hotmail.com> wrote: yes correct.
