Hi,
I experienced a very strange problem today where my gem0 interface on
sparc64 4.6 release stopped passing traffic or doing anything at all. It
was very strange. ifconfig looked normal, there were no errors logged on
the console, daemon, messages etc. I bounced the interface with ifconfig
and it started passing traffic again.
Is there any way for me to pull more detailed stats out of the interface
so I can see what's going on? For example the device registers stats?
Here is my console session from fixing the problem

After that, everything was working fine. Any thoughts?
