Invalid Ordered Sets

I've looked around and have found limited resources with troubleshooting a possible issue I'm having in my Brocade M5424.


From the manaul I've read my fillword is suppose to be set to 0, which it is. So, any documentation on what else my problems could be? Sorry if this is a simple quesiton I recently inherited this thing.

Re: Invalid Ordered Sets

These stats were cleared a year ago so you might want to create a new baseline first.


Enter the command "statsclear".


Then check if they are increasing.
