Fabric Watch: portstate stays Out_Of_Range although current value is in range

Hi,

I am using Fabric Watch on some v6.4.1a DCX. I want to get an errorlog entry for every status change of a port, for example every time a signal loss on a port occurs. I tried setting the Threshold Configuration like:

Time Base: Seconds

Low Boundary: 0

High Boundary: 0

Buffer Size: 0

With Alarm Configuration:

Changed: ERROR_LOG

So I would expect every time a signal loss happens I get an entry that the value is 1 Error/s and a second that the value is 0 Error/s and this seems to work. But additionaly the Ports get MARGINAL and stay MARGINAL, I believe because the state of the port in Fabric Watch like this:

Name    State    Reason    Last Value    Current Value    Time   
portLink008    Out_Of_Range    Low Above    1 Error(s)/sec    0 Error(s)/sec    

Shouldn't the state of the ports go back to In_Range again as the current Value 0 indicates?

Primus emc225204 looks a bit like that, but it predicts a fix in FOS 6.4.x

Any thoguhts?
