Troubleshooting Tip for Port Stats
As a general rule, you should clear all the counters by choosing Clear Port Stats
or Clear All Port Stats after you have resolved a problem. When troubleshooting,
keep track of the time interval when errors accumulate to judge the presence and
severity of a problem. (There is a link recovery hierarchy implemented in Fibre
Channel to handle some level of "expected anomalies.") For troubleshooting
purposes, you want to focus on errors that, as displayed in the Counter column,
increment very quickly.
