creditrecovmode and fault options

Is it possible to remove or reset the "fault" option...i.e "creditrecovmode --fault [edgeblade | edgecoreblade | coreblade]" from appearing, once it's been defined. As well as remove the "LR threshold (not currently activated): 2" line from appearing when entering the "creditrecovmode --show",  as "onLrThresh".  Hopefully, the following output will clairfy the issue:

 

Figure 1.  creditrecovmode oringally cfigured as follows:

creditrecovmode --cfg onLrThresh -lrthreshold 2    

creditrecovmode -fault EDGECOREBLADE

creditrecovmode --fe_crdloss on

 

creditrecovmode --show

Internal port credit recovery is Enabled with LrThresh
Back end port Loss of Sync's Link Reset is Enabled with LrThresh
LR threshold (currently activated): 2
Fault Option : EDGECOREBLADE
C2 FE Complete Credit Loss Detection is Enabled

 

Figure 2.  Then reconfigured / redefined as follows:

creditrecovmode --cfg on onLrOnly

creditrecovmode --fe_crdloss on

 

creditrecovmode --show

Internal port credit recovery is Enabled with LrOnly
Back end port Loss of Sync's Link Reset is Enabled with LrOnly
LR threshold (not currently activated): 2
Fault Option : EDGEBLADE
C2 FE Complete Credit Loss Detection is Enabled

 

How can I remove thes following two lines from the "creditrecovmode --show" command output, can the Fault Option be removed or reset to "" once it's been defined?

LR threshold (not currently activated): 2
Fault Option : EDGEBLADE

Re: creditrecovmode and fault options

In order to activate the threshold, you have to do: creditrecovmode --cfg onLrThresh -lrthreshold 2

Fault option has to be set to one of the three values. The only way to turn it off, I believe, is to disable the creditrecovmode completely. But my opinion is you'd better enable it with at least edge blade option. If an internal port keeps failing, your switch has to react accordingly instead of slowing down the traffic and putting the entire fabric at risk.
