Re: how to isolate B2B credit Zero increase

Hello,

 

this counter will increase by 1 every 2,5 microsecond when the port credit value is zero.

In normal operation you may detect  some low values on this counter, which don't represent any issue.

 

Othervise If you will see c3discards  on particularr port, than you have to focus more on that.

 

Please refer to this article to get better overview:
