Configuration
System
System Configuration
This page shows system configuration information. User can configure lots of
information as below:
Figure 2-1
MAC Address: Displays the unique hardware address assigned by
manufacturer (default).
S/W Version: Displays the switch’s firmware version.
H/W Version: Displays the switch’s Hardware version.
DHCP Enabled: Click the box to enable DHCP
Fallback IP address: Manually assign the IP address that the network is using.
The default IP is 192.168.2.1
Fallback Subnet Mask: Assign the subnet mask to the IP address
Fallback Gateway: Assign the network gateway for industrial switch. The
default gateway is 0.0.0.0.

Management VLAN: ID of a configured VLAN (1-4094) through which you can
manage the switch. By default, all ports on the switch are members of VLAN 1.
However, if the management VLAN is changed, the management station must
be attached to a port belonging to this VLAN.
Name: Type in the new user name (The default value is ‘admin’).
Password: Type in the new password (The default value is ‘admin’).
SNMP Enabled: Enables or disables SNMP on the switch. Supports SNMP
version 1and 2c management clients.
SNMP Trap Destination: IP address of the trap manager to receive notification
messages from this switch. Traps indicating status changes are issued by the
switch to specified trap managers. You must specify trap managers so that key
events are reported by this switch to your management station.
SNMP Read Community: A community string that acts like a password and
permits access to the SNMP database on this switch.
SNMP Trap Community: Community string sent with the notification operation.
Ports
Port Security ensures access to a switch port based on MAC address, limits the
total number of devices from using a switch port, and protects against MAC
flooding attacks.
Port Configuration
In Port Configuration, you can set and view the operation mode for each port.
Enable Jumbo Frames:This switch provides more efficient throughput for large
sequential data transfers by supporting jumbo frames on Gigabit Ethernet ports
up to 9216 bytes. Compared to standard Ethernet frames that run only up to
1.5 KB, using jumbo frames significantly reduces the per-packet overhead
required to process protocol encapsulation fields.
Power Saving Mode:Adjusts the power provided to ports based on the length
of the cable used to connect to other devices. Only sufficient power is used to
maintain connection requirements.
Mode: allow user to manually set the port speed such as Auto, 10 half, 10 Full,
100 Half, 100 Full, 1000 Full or Disabled. User may press Apply button to
complete the configuration procedure.

Figure 2-2
VLAN
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allow you to isolate network traffic, so only the members of
the same VLAN will receive traffic from the ones of the same VLAN. Basically,
creating a VLAN from a switch is logically equivalent of reconnecting a group of
network devices to another Layer 2 switch. However, all the network devices are
still plugged into the same switch physically.
Port Segmentation (VLAN) Configuration
VLAN ID: ID of configured VLAN (1-4094, no leading zeroes).
VLAN Configuration List: Lists all the current VLAN groups created for this
system. Up to 16 VLAN groups can be defined. VLAN 1 is the default untagged
VLAN.

Figure 2-3
Aggregation
Port trunk allows multiple links to be bundled together and act as a single physical
link for increased throughput. It provides load balancing, and redundancy of links
in a switched inter-network. Actually, the link does not have an inherent total
bandwidth equal to the sum of its component physical links. Traffic in a trunk is
distributed across an individual link within the trunk in a deterministic method that
called a hash algorithm. The hash algorithm automatically applies load balancing
to the ports in the trunk. A port failure within the trunk group causes the network
traffic to be directed to the remaining ports. Load balancing is maintained
whenever a link in a trunk is lost or returned to service.
Aggregation / Trunking Configuration
To assign a port to a trunk, click the required trunk number, then click Apply.
Figure 2-4

LACP
IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by
automatically aggregating several physical links together as a logical trunk and
providing load balancing and fault tolerance for uplink connections.
LACP Port Configuration
Port: The port number.
Enabled: Enables LACP on the associated port.
Key Value: Configures a port's LACP administration key. The port
administrative key must be set to the same value for ports that belong to the
same link aggregation group (LAG). If this administrative key is not set when an
LAG is formed (i.e., it has the null value of 0), this key will automatically be set
to the same value as that used by the LAG.
Figure 2-5
RSTP
IEEE 802.1w Rapid Spanning tree protocol (LACP) provides a loop-free network
and redundant links to the core network with rapid convergence to ensure faster

recovery from failed links, enhancing overall network stability and reliability.
RSTP System Configuration
System Priority: This parameter configures the spanning tree priority globally
for this switch. The device with the highest priority becomes the STP root
device. However, if all devices have the same priority, the device with the
lowest MAC address will then become the root device. Number between 0 -
61440 in increments of 4096. Therefore, there are 16 distinct values.
Hello Time: Interval (in seconds) at which the root device transmits a
configuration message (BPDU frame). Number between 1-10 (default is 2).
Max Age –The maximum time (in seconds) a device can wait without receiving
a configuration message before attempting to reconfigure. That also means the
maximum life time for a BPDU frame. Number between 6-40 (default is 20).
Forward Delay: The maximum time (in seconds) the root device will wait before
changing states (i.e., discarding to learning to forwarding). Number between
4 –30 (default is 15).
Force Version: Set and show the RSTP protocol to use. Normal - use RSTP,
Compatible - compatible with STP.
Figure 2-6-1
RSTP Port Configuration
Port: The port ID. It cannot be changed. Aggregations mean any configured
trunk group.
Enabled: Click on the tick-box to enable/disable the RSTP protocol for the port.
Edge: Expect the port to be an edge port (linking to an end station) or a link to
another STP device.
Path Cost: This parameter is used by the STP to determine the best path
between devices. Therefore, lower values should be assigned to ports attached
to faster media, and higher values assigned to ports with slower media. Set the
RSTP path cost on the port. Number between 0 - 200000000. 0 means auto
generated path cost.

Figure 2-6-2
802.1X
802.1X provides port-based authentication, which involves communications
between a supplicant, authenticator, and authentication server. Port refers to a
single point of attachment to the LAN infrastructure. The supplicant is often
software on a client device, such as a laptop; the authenticator us a network
device, such as an Ethernet switch or wireless access point; and the
authentication server is typically a host running software supporting the RADIUS
and EAP protocols.
Port-based Network access control (PNAC) ensures all users are authorized
before being granted access to the network. User authentication is carried out
using any standard-based RADIUS server.

802.1X Configuration
Mode: Enables or disables 802.1X globally for all ports on the switch. The
802.1X protocol must be enabled globally for the switch before the port settings
are active. (Default: Disabled)
RADIUS IP: Address of authentication server.
RADIUS UDP Port: Network port of authentication server used for
authentication messages. (Range: 1-65535; Default: 1812)
RADIUS Secret: Sets the text string used for encryption between the switch
and the RADIUS server. This key is used to authenticate logon access for the
client. Do not use blank spaces in the string. (Maximum length: 48 characters).
Figure 2-7
IGMP Snooping
IGMP Snooping is the process of listening to IGMP network traffic. IGMP
Snooping, as implied by the name, is a feature that allows a layer 2 switch to
“listen in” on the IGMP conversation between hosts and routers by processing the
layer3 IGMP packets sent in a multicast network.
When IGMP Snooping is enabled in a switch, it analyzes all IGMP packets
between hosts connected to the switch and multicast routers in the network.
When a switch hears an IGMP report from a host for a given multicast group, the

switch adds the host’s port number to the multicast list for that group. Moreover,
when the switch hears an IGMP Leave, it removes the host’s port from the table
entry.
Prevents flooding of IP multicast traffic, and limits bandwidth intensive video traffic
to only the subscribers.
IGMP Configuration
IGMP Enabled: When enabled, the switch will monitor network traffic to
determine which hosts want to receive multicast traffic.
Router Ports: Set if ports are connecting to the IGMP administrative routers.
Unregistered IPMC Flooding enabled: Set the forwarding mode for
unregistered (not-joined) IP multicast traffic. The traffic will flood when enabled,
and forward to router-ports only when disabled.
IGMP Snooping Enabled: When enabled, the port will monitor network traffic to
determine which hosts want to receive the multicast traffic.
IGMP Querying Enabled: When enabled, the port can serve as the Querier,
which is responsible for asking hosts if they want to receive multicast traffic.
Figure 2-8
Mirroring
Port Mirroring is used on a network switch to send a copy of network packets seen
on one switch port (or an entire VLAN) to a network monitoring connection on
another switch port. This is commonly used for network appliances that require
monitoring of network traffic, such as an intrusion-detection system.
Mirroring Configuration
Port to Mirror to: The port that will “duplicate” or “mirror” the traffic on the source
port. Only incoming packets can be mirrored. Packets will be dropped when the
available egress bandwidth is less than ingress bandwidth.
Ports to Mirror: Select the ports that you want to mirror from this section of the
page. A port will be mirrored when the “Mirroring Enabled” check-box is
checked.

Figure 2-9
Quality of Service (QoS)
In QoS Mode, select QoS Disabled, 802.1p, or DSCP to configure the related
parameters.
QoS Configuration
Strict: Services the egress queues in sequential order, transmitting all traffic in
the higher priority queues before servicing lower priority queues.
WRR: Weighted Round-Robin shares bandwidth at the egress ports by using
scheduling weights with default values of 1, 2, 4, 8 for queues 0 through 7,
respectively. (This is the default selection.)
※Note: WRR can only be selected if Jumbo Frame mode is disabled on the
Port Configuration page

Figure 2-10-1
QoS Mode: QoS Disabled
When the QoS Mode is set to QoS Disabled, the following table is displayed.
QoS Mode: 802.1p
Packets are prioritized using the 802.1p field in the VLAN tag. This field is three
bits long, representing the values 0 - 7. When the QoS Mode is set to 802.1p, the
802.1p Configuration table appears, allowing you to map each of the eight 802.1p
values to a local priority queue (low, normal, medium or high). The default settings
are shown below.
When the QoS Mode is set to 802.1p, the 802.1p Configuration table is displayed
as shown below.
Figure 2-10-2
QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code
Point) value. The Differentiated Services Code Point (DSCP) is a six-bit field that
is contained within an IP (TCP or UDP) header. The six bits allow the DSCP field
to take any value in the range 0 - 63. When QoS Mode is set to DSCP, the DSCP
Configuration table is displayed, allowing you to map each of the DSCP values to
a hardware output queue (low, normal, medium or high). The default settings map
