Note: When port channel 128 is added to the vlt domain the MTU setting is automatically changed to 9216.
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 on all host interfaces that support flow control. In
OS10EE this is enabled by default, in OS9 it must be configured. Flow Control is configured with the
flowcontrol rx on tx off command.
