Use this screen to view and configure switch port settings. The port settings page allows you change the configuration of the ports on the switch in order to find the best balance of speed and flow control according to your preferences. Configuring Gigabit ports require additional factors to be considered when arranging your preferences for the switch compared to 10/100 ports.
To access the page, click Port Settings under the System menu.
Click Apply to save settings.
Use the System Time screen to view and adjust date and time settings.The switch supports Simple Network Time Protocol (SNTP). SNTP ensures accurate network device clock time synchronization up to the millisecond. Time synchronization is performed by a network SNTP server. This switch operates only as an SNTP client and cannot provide time services to other systems.
To configure date/time through SNMP:
Next to the Enable SNTP, select Enable.
In the Time Zone Offset list, select by country or by the GMT time zone where the switch is located.
Next select Disabled, Recurring, or Non-Recurring for Daylight Savings Time. Daylight saving is a period from late Spring to early Fall when many countries set their clocks forward or backward by one hour to give more daytime light in the evening.
In the SNTP/NTP Server Address field, enter the IP address or the host name of the SNTP/NTP server.
Finally, enter the port number on the SNTP server to which SNTP requests are sent. The valid range is from 1–65535. The default is: 123.
Click Apply to update the system settings.
To configure date/time manually:
Next to the Enable SNTP, select Disable.
In the Manual Time field, use the drop-down boxes to manually select the date and time you wish to set.
In the Time Zone Offset list, select by country or by the Coordinated Universal Time (UTC/GMT) time zone in which the switch is located.
Next select Disabled, Recurring or Non-recurring for Daylight Savings Time. Daylight saving is a period from late Spring to early Fall when many countries set their clocks forward or backward by one hour to give more daytime light in the evening.
Click Apply to update the system settings.

Port
Displays the port number.
Link Status
Indicates whether the link is up or down.
Mode
Select the speed and the duplex mode of the Ethernet connection on this port.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When auto-negotiation is turned on, a port on the switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support auto-negotiation or turns off this feature, the switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the switch's auto-negotiation is turned off, a port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer port are the same in order to connect.
Flow Control
A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses. Flow Control is used to regulate transmission of signals to match the bandwidth of the receiving port. The switch uses IEEE 802.3x flow control in full duplex mode and backpressure flow control in half duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the sending port (mimicking a state of packet collision) causing the sending port to temporarily stop sending signals and resend later.

Users can select the Management VLAN ID from drop-down list and please note all ports connected to APs on the switch should be configured to the same VLAN ID as this EWS switch’s management VLAN ID to let AP management function works properly.
Energy Efficient Ethernet (EEE), an Institute of Electrical and Electronics Engineers (IEEE) 802.3az standard, reduces the power consumption of physical layer devices during periods of low link utilization. EEE saves energy by allowing PHY non-essential circuits to shut down when there is no traffic.
Network administrators have long focused on the energy efficiency of their infrastructure, and the EnGenius Layer 2 switch complies with the IEEE’s Energy-Efficient Ethernet (EEE) standard. The EEE compliant switch offers users the ability to utilize power that Ethernet links use only during data transmission. Lower Power Idle (LPI) is the method for achieving the power saving during Ethernet ideal time.
Use the EEE configuration page to configure Energy Efficient Ethernet.
