Note 1: The above configuration is specific to the system under test presented here and may not be directly 

applicable to all use cases. Please consult your local network administrator or refer to the Cisco Nexus 3548 

Command Reference (see the link in the appendix) for more information. 

Note 2: The above configuration also specifies send/recv flow control and No Drop mode enabled. This prevents 

the switch from dropping packets on the network with a combined use of port buffer management and network 

pause. These settings are specific to the test. In some application instances, it may be optimal not to enable 
send/recv flow control and ‘no drop’ mode.
