Full Duplex Flow	Set the flow control feature on each port for a specific mode. The
Control	choices are as follows:
(Selectable)	Symmetric – the port operates in Symmetric mode, causing the port to
	interpret received PAUSE frames and allow the port to transmit PAUSE
	frames when necessary at any speed connection.
	Asymmetric Rx – the port operates in Asymmetric Rx mode, causing
	the port to interpret received PAUSE frames and prevent the port from
	transmitting PAUSE frames. This option is for Gigabit only.
	Asymmetric Tx – the port operates in Asymmetric Tx mode, causing
	the port to ignore PAUSE frames and allow the port to transmit PAUSE
	frames when necessary. This option is for Gigabit only.
	Disabled – full duplex flow control is off, causing the port to ignore
	received PAUSE frames and prevent the port from transmitting PAUSE
	frames at any speed connection.
	Auto-Negotiate – when supported, the maximum flow control
	capabilities of the port are reflected in the PAUSE bits of the
	Auto-Negotiation registers. The ports’ flow control operational state is
	determined by the results of Auto-Negotiation. This option is not
	displayed if Auto-Negotiation is not supported on this port.
	To change the settings for full duplex flow control, refer to
	Section 5.3.1.
Half Duplex Flow	Set the Half Duplex flow control mode. Back pressure half duplex flow
Control	control is enabled when the port is set On, and disabled when the port
(Toggle)	is set Off. To change the settings, refer to Section 5.3.1.
SAVE TO ALL	Apply the currently displayed settings on the screen to all ports. To
PORTS	save the settings to all ports, highlight this command and press
(Command)	ENTER.
