Draytek 2750 manual Auto Flow Control, Maximum Frame, Power Control

Auto.

Flow Control	If flow control is enabled by checking Configured box, both
	parties can send PAUSE frame to the transmitting device(s) if
	the receiving port is too busy to handle. If not, there will be no
	flow control in the port. It drops the packet if too much to
	handle.
	Current Rx: indicates whether pause frames on the port are
	obeyed.
	Current Tx: indicates whether pause frames on the port are
	transmitted.
Maximum Frame	This module offers 1522~9600 (Bytes) length to make the long
	packet for data transmission.

Excessive Collision Mode There are two modes for you to choose when excessive collision happened in half-duplex condition.

	Discard - It determines whether the MAC drops frames after an
	excessive collision has occurred. If yes, a frame is dropped after
	excessive collision. This is IEEE Standard 802.3 half-duplex
	flow control operation.
	Restart - It determines whether the MAC retransmits frames
	after an excessive collision has occurred. If set, a frame is not
	dropped after excessive collisions, but the backoff sequence is
	restarted. This is a violation of IEEE Standard 802.3, but is
	useful in non-dropping half-duplex flow control operation.
Power Control	The Configured column allows for changing the power savings
	mode parameters per port.

	Disabled: All power savings mechanisms disabled.
	ActiPHY: Link down power savings enabled.
	PerfectReach: Link up power savings enabled.
	Enabled: Both link up and link down power savings enabled.
Refresh	Click this button to refresh the information for LAN ports.

After finishing all the settings here, please click OK to activate them.
