[ewg] How to monitor traffic with IBoE/RoCEE?

[Tom Ammon]

A widely-supported method for collecting statistics from ethernet 
switching devices is SNMP. As Woody said, you wouldn't manage your 
ethernet network any differently than you do now. In addition many many 
tools have been written to make use of SNMP counters, so you won't have 
a hard time finding tools, both commercial and open source.
