7. Use Expert to analyze the capture, and verify the following:
 No error occurs on FCoE traffic
 Link throughput per priority in MBps (Figure 5-20)
 Each traffic class can still generate I/O at its ETS setting when the link
is saturated.
 Exchange completion time

Validation Results
Table 5-3 lists the port settings to verify the ETS setup. ETS allocates 50 percent
of the bandwidth to FCoE and 50 percent of the bandwidth to other traffic. The
other traffic is regular TCP traffic.
