The downstream interfaces will be configured in the next section. Dell recommends asymmetrical flow control
(rx on tx off) on S4048-ON leaf switches which have sufficient egress buffers to reduce packet drops and
resulting retransmissions. This feature should be applied to all host interfaces that support flow control. In
OS10EE this is enabled by default, in OS9 it must be configured. Flow control commands are added below
for reference; however, they are not required in OS10EE.
