5–Validation Methods for DCB and FCoEValidation Step 5—ETS Verification51031-00 A 5-23The next step is to verify that the switch allows more TCP traffic when morebandwidth is available. Figure 5-25 shows that the TCP traffic increases to741MBps after stopping the FCoE traffic. Again, the switch is behaving properly.Figure 5-25. LAN Traffic OnlyTable 5-4 summarizes the throughput achieved for the previous three tests.The test continues cycling FCoE traffic and TCP traffic on and off. The resultsshow that the switch continues to enforce the ETS configuration, allows both TCPand FCoE to use additional bandwidth when available, and maintains minimumguaranteed bandwidth to both traffic classes.Table 5-4.
