lan3 current values: New Transmit Flow Control = Off • Attempting to turn on Rx flow control for a Flex-10 interface on which the MTU size is greater than 1500 (enabling Jumbo Frames) brings up the warning message shown in the following example. The Rx flow control cannot be turned on in this instance, so the specified value (on) is invalid; Rx flow control remains turned off.
