interfaces.
The IP Setting page contains fields for assigning IP addresses. IP addresses are either
defined as static or are retrieved using the Dynamic Host Configuration Protocol (DHCP).
DHCP assigns dynamic IP addresses to devices on a network. DHCP ensures that
network devices can have a different IP address every time the device connects to the
network.
To access the page, click

Port Settings
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 10/100Mb ports.
To access the page, click Port Settings under the System menu.

Flow Control
Displays the port number.
Indicates whether the link is up or down.
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 autonegotiation 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.
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.

DHCP Snooping
DHCP snooping is a DHCP security feature that provides security by filtering untrusted DHCP
messages and by building and maintaining a DHCP snooping binding table. An untrusted message
is a message that is received from outside the network or firewall and that can cause traffic
attacks within your network.
18
The DHCP snooping binding table contains the MAC address, IP address, lease time, binding type,
VLAN number, and interface information that corresponds to the local untrusted interfaces of a
switch; it does not contain information regarding hosts interconnected with a trusted interface.
An untrusted interface is an interface that is configured to receive messages from outside the
network or firewall. A trusted interface is an interface that is configured to receive only messages
from within the network.
DHCP snooping acts like a firewall between untrusted hosts and DHCP servers. It also gives you a
way to differentiate between untrusted interfaces connected to the end-user and trusted
interfaces connected to the DHCP server or another switch.
Global Settings
The global settings allow you to enable or disable DHCP snooping feature. You can also enable the

EEE
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 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.

L2 Feature
The L2 Feature tab exhibits complete standard-based Layer 2 switching capabilities, including:
Link Aggregation, 802.1D Spanning Tree Protocol, 802.1w Rapid Spanning Tree Protocol,
802.1s Multiple Spanning Tree Protocol, MAC Address Table, Internet Group Management
Protocol (IGMP) Snooping, Port Mirroring, 802.1ab Link Layer Discovery Protocol (LLDP), and
Multicast Listener Discovery (MLD) snooping. Utilize these features to configure the Switch to
your preferences.
Link Aggregation
A Link Aggregation Group (LAG) optimizes port usage by linking a group of ports together to form
a single, logical, higher-bandwidth link. Aggregating ports multiplies the bandwidth and increases
port flexibility for the Switch. Link Aggregation is most commonly used to link a bandwidth
intensive network device (or devices), such as a server, to the backbone of a network.
The participating ports are called Members of a port trunk group. Since all ports of the trunk
group must be configured to operate in the same manner, the configuration of the one port of the
trunk group is applied to all ports of the trunk group. Thus, you will only need to configure one of
any of the ports in a trunk group. A specific data communication packet will always be
transmitted over the same port in a trunk group. This ensures the delivery of individual frames of
a data communication packet will be received in the correct order. The traffic load of the LAG will
be balanced among the ports according to Aggregate Arithmetic. If the connections of one or
several ports are broken, the traffic of these ports will be transmitted on the normal ports, so as
to guarantee the connection reliability.
When you aggregate ports, the ports and LAG must fulfill the following conditions:
•
All ports within a LAG must be the same media/format type.
•
A VLAN is not configured on the port.
•
The port is not assigned to another LAG.
•
The Auto-negotiation mode is not configured on the port.
•
The port is in full-duplex mode.
•
All ports in the LAG have the same ingress filtering and tagged modes.
•
All ports in the LAG have the same back pressure and flow control modes.
•
All ports in the LAG have the same priority.
•
All ports in the LAG have the same transceiver type.
•
Ports can be configured as LACP ports only if the ports are not part of a previously
configured LAG.
LACP is a dynamic protocol which helps to automate the configuration and maintenance of LAG’s.
The main purpose of LACP is to automatically configure individual links to an aggregate bundle,
while adding new links and helping to recover from link failures if the need arises. LACP can
monitor to verify if all the links are connected to the authorized group. LACP is a standard in
25
computer networking; hence LACP should be enabled on the Switch's trunk ports initially in order
for both the participating Switches/devices that support the standard to use it.
Port Trunking
Port Trunking allows you to assign physical links to one logical link that functions as a single,
higher-speed link, providing dramatically increased bandwidth. Use Port Trunking to bundle
multiple connections and use the combined bandwidth as if it were a single larger pipe.
Important: You must enable Trunk Mode before you can add a port to a trunk group.

Select the ports you wish to add into the trunk group. Up to eight ports
per group can be assigned.
Static: The Link Aggregation is configured manually for specified trunk
group.
LACP: The Link Aggregation is configured dynamically for specified trunk
group.
LACP allows for the automatic detection of links in a port trunking group
when connected to a LACP-compliant Switch. You will need to ensure
that both the Switch and device connected to are in the same mode in
order for them to function, otherwise they will not work. Static
configuration is used when connecting to a Switch that does not support
LACP.
Click the Apply button to accept the changes or the Cancel button to discard
them.
LACP Settings
Assign a system priority to run with Link Aggregation Control Protocol (LACP) and is become for a
backup link if a link goes down. The lowest system priority is allowed to make decisions about
which ports it is actively participating in in case a link goes down. If two or more ports have the
same LACP port priority, the port with the lowest physical port number will be selected as the
backup port. If a LAG already exists with the maximum number of allowed port members, and
LACP is subsequently enabled on another port using a higher priority than an existing member,
the newly configured port will replace the existing port member that has a lower priority. A
smaller number indicates a higher priority level. The range is from 0-65535 and default is:
32768.

Click Apply to save settings.
LACP Timeout
Link Aggregation Control Protocol (LACP) allows the exchange of information with regard to the
link aggregation between two members of aggregation. The LACP Time Out value is measured in a
periodic interval. Check first whether the port in the trunk group is up. When the interval expires,
it will be removed from the trunk. Set a Short Timeout (one second) for busy trunked links to
ensure that disabled ports are removed from the trunk group as soon as possible. The default
value for LACP time out is: Long Timeout.
28
Timeout
Click Apply to save settings.
Select the administrative LACP timeout.
Long Timeout: The LACP PDU will be sent for every 30 seconds, and the LACP
timeout value is 90 seconds.
Short Timeout: The LACP PDU will be sent every second. The timeout value is 3
seconds.
Mirror Settings
Mirrors network traffic by forwarding copies of incoming and outgoing packets from specific
ports to a monitoring port. The packet that is copied to the monitoring port will be the same
format as the original packet.
Port mirroring is useful for network monitoring and can be used as a diagnostic tool. Use port
mirroring to send traffic to applications that analyze traffic for purposes such as monitoring
compliance, detecting intrusions, monitoring and predicting traffic patterns, and other correlating
events. Port Mirroring is needed for traffic analysis on a Switch because a Switch normally sends
packets only to the port to which the destination device is connected. The analyzer captures and
evaluates the data without affecting the client on the original port. Port mirroring can consume
significant CPU resources while active, so be cautious of such usage when configuring the
Switch.

Sets the source port from which traffic will be mirrored.
TX Port: Only frames transmitted from this port are mirrored to the
destination port.
RX Port: Only frames received on this port are mirrored to the
destination port.

the specified destination port.

Select whether to enable or disable ingress traffic forwarding.
Select whether to enable or disable port mirroring.
Note: You cannot mirror a faster port onto a slower port. For example, if you try to mirror the
traffic from a 100Mbps port onto a 10Mbps port, this can cause throughput problems. The
port you are copying frames from should always support an equal or lower speed than the
port to which you are sending the copies. Please note a target port and a source port cannot
be the same port.
