3. PreparationforWebInterface
The Web management page allows you to use a standard Web browser — such as
Microsoft Internet Explorer, Google Chrome or Mozila Firefox — to configure and
interrogate the switch from anywhere on the network.
Before you attempt to use the Web user interface to manage switch operation, verify
that your switch is properly installed on your network and that every PC on this network
can access the switch via the Web browser.
1. Verify that your network interface card (NIC) is operational, and that your operating
system supports the TCP/IP protocol.
2. Power on the switch and connect your computer to the switch.
3. The switch default IP address is 192.168.2.1. The switch and the connected PC(s)
should locate within the same IP subnet.
4. Change your computer's IP address to 192.168.2.XX or another IP address that is
located in the 192.168.2.x subnet. (For example: IP address = 192.168.2.30; subnet
mask = 255.255.255.0)
Launch the Web browser and log in.
5. Launch the Web browser on the PC.
6. Enter “http://192.168.2.1” (or the IP address of the switch), then press <Enter>.
7. The login screen will appear next.
8. Key in the password. Default password is no password. Click Apply.
10

4. WebUIConfiguration
This part instructs you how to set up and manage the switch through the Web user
interface.
4.1 Configuration
This section shows how to configure the switch settings.
4.1.1 System Configuration
What follows is system configuration information.
MAC Address: Displays the unique hardware address assigned by the manufacturer
(default).
S/W Version: Displays the switch’s firmware version.
H/W Version: Displays the switch’s hardware version.
Active IP Address: The current active IP address of the switch.
Active Subnet mask: The current active subnet mask of the IP address.
Active Gateway: The current active gateway of the switch.
DHCP Server: The IP of the DHCP server. Displays after DHCP Client is enabled.
Lease Time Left: Display after DHCP Client is enabled.
12
DHCP Enabled: Click the box to enable DHCP Client mode.
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 an industrial switch. The default
gateway is 192.168.2.254.
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: Enter the new user name information.
Password: Enter the new password (the default value is no password).
SNMP Enabled: Enables or disables SNMP on the switch. Supports SNMP version 1 and
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.
13
SNMP Read Community: A community string that acts like a password and permits access
with Read privilege to the SNMP database on this switch. Authorized management
stations are only able to retrieve MIB objects.
SNMP Write Community: A community string that acts like a password and permits access
with Write privilege to the SNMP database on this switch. Authorized management
stations are able to modify the value of the MIB objects.
SNMP Trap Community: A community string sent with the notification operation.
4.1.2 Ports
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: Allows user to manually set the port speed, such as Auto, 10 half, 10 Full, 100 Half,
100 Full, 1000 Full or Disabled. Click Apply to complete the configuration procedure.
Flow Control: Allows you to manually enable or disable the Flow Control feature. Check
the box of the specific ports you want, the click Apply to complete the configuration
procedure.
14
15
4.1.3 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 each other. Basically, creating a VLAN from a switch is logically the 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 a configured VLAN (1-4094, no leading zeroes). Enter the new ID and click
Add. The Web UI is directed to the VLAN Setup screen.
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.
VLAN Setup Configuration
This screen allows you to select the member ports of the VLAN you added. Select the
ports and click Apply to activate.
16
4.1.4 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
internetwork. 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 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 the ports to a trunk, click the required trunk number ports, then click Apply.
The below example shows that Ports 3 and 4 are the member ports of Trunk Group 1.
4.1.5 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. Once the port is configured as a Static
Aggregation port, the area will become gray. It means a port can only be a member of the
Aggregation or LACP.
LACP Port Configuration
Port: The port ID.
Protocol Enabled: Enables LACP Protocol on the associated port.
Key Value: Configures a port's LACP administration key. The port administrative key must
17
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.
18
4.1.6 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 and 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 and 10 (default is 2).
Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. This also means the maximum
lifetime for a BPDU frame. Number between 6 and 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 and 30 (default is 15).
Force Version: Set and show the RSTP protocol to use. Normal - use RSTP; Compatible -
compatible with STP.
RSTP Port Configuration
Port: The port ID. Aggregations mean any configured trunk group.
Protocol Enabled: Select 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.
19
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 and 200000000. The default value is “auto,” meaning the system
will automatically generate path cost.
20
4.1.7 802.1X Configuration
IEEE802.1X provides a security standard for network access control, especially in Wi-Fi
wireless networks. 802.1X holds a network port disconnected until authentication is
completed. The switch uses Extensible Authentication Protocol over LANS to exchange
authentication protocol client identity with the client, and forward it to another remote RADIUS
authentication server to verify access rights. The EAP packet from the RADIUS server also
contains the authentication method to be used. The client can reject the authentication
method and request another, depending on the configuration of the client software and the
RADIUS server. Depending on the authenticated results, the port is either made available to
the user or the user is denied access to the network.
The RADIUS servers make the network a lot easier to manage for the administrator by
gathering and storing the user lists.
Mode: By default, 802.1x is disabled. To use EAP for security, select enabled and set the
802.1X Global Settings for the Radius Server and applicable authentication information.
RADIUS server IP: The IP Address of the external Radius Server, you need to specify an
RADIUS server to enable 802.1X authentication.
RADIUS UDP Port: The UDP port used for the communication between the switch and
RADIUS server.
RADIUS Secret: The Key used for the communication between the switch and RADIUS
server.
Port: The port ID.
21
Admin State: There are 3 types: Auto, Force Authorized and Force Unauthorized.
- Auto: Select Auto when you enabled the IEEE 802.1X. If the client is successfully
authorized, the port is authorized to be used as well. Otherwise, the port can’t be used.
- Force Authorized: The default value. Whether the IEEE 802.1X is enabled or not, the port
is always authorized to be used.
- Force Unauthorized: Whether the IEEE 802.1X is enabled or not, the port is always
unauthorized to be used.
Port State: It indicates the status of the port. Authorized means the port is successfully
authorized by the RADIUS server or the port is configured as “Force Authorized.”
Others: Re-authenticate allows restart the authentication process, Force Reinitialize
reinitializes the process and Statistics displays the IEEE 802.1X counters and information
of each port.
22
4.1.8 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 Layer 3 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. And, when the switch hears an IGMP Leave, it
removes the host’s port from the table entry. It also prevents flooding of IP multicast traffic,
and limits bandwidth-intensive video traffic to only the subscribers.
IGMP Configuration
IGMP Enabled: When this is 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.
23
4.1.9 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” option is selected.
24
4.1.10 QoS
In QoS Mode, select QoS Disabled, 802.1p or DSCP to configure the related parameters.
QoS Mode: QoS Disabled
When the QoS Mode is set to QoS Disabled, the QoS is disabled.
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. The Custom Prioritize Traffic is the default and suggested value.
25
QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code Point) value.
The 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 all DSCP
values to the high-priority egress queue.
User can use the Prioritize Traffic drop-down list to quickly set the values in the DSCP
Configuration table to a common priority queue. Use Custom if you want to set each value
individually.
When the QoS Mode is set to DSCP, the DSCP Configuration table is displayed as shown
below. Enter the DSCP Value and Priority mapping in the fields on the bottom half.
26
Queue Mode:
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 screen.
4.1.11 Filter Configuration
There are three modes that you can choose for filter configuration:
Disabled: When this mode is disabled, there is no protection here.
Static: The IP address you entered here can’t access the switch.
DHCP: The IP address retrieved from the DHCP server can’t access the switch.
27
4.1.12 PoE (Power over Ethernet) Configuration
PoE technology is a system to pass electrical power safely, along with data, on Ethernet
cabling. Power is supplied in common mode over two or more of the differential pairs of wires
found in the Ethernet cables and comes from a power supply within a PoE-enabled
networking device (such as a switch) or can be injected into a cable run with a midspan power
supply.
This screen shows the PoE status when connected or disconnected to the PD device.
PoE Enabled: POE of the port is able to supply power to the attached PD (powered
device).
PD Class: Detect the class of PD.
Delivering Power (W): Output power from the switch to the PD.
Current (mA): The status of the port current.
Power Budget [%] ( Per 8 port total power = 130W): You can see the percentage change
on this screen.
The green shows the status of the connected PD. To protect the system and improve product
life, lower than 80% Power Budget is suggested.
28
4.1.13 Rate Limit Configuration
Type of Port: You can define the certain port as Policer and Shaper before you set up the rate
limit.
No Limit: This drop-down menu allows you to specify that the selected port will have no
bandwidth limit.
Rate (kbps): This drop-down menu also allows you to select the data rate in kbits per second
for the selected port. The value is between 128 kbps and 3968 kbps.
29
4.1.14 Storm Control
Broadcast storms may occur when a device on your network is malfunctioning, or if
application programs are not well designed or properly configured. If there is too much
broadcast traffic on your network, performance can be severely degraded or everything can
come to complete halt.
You can protect your network from broadcast storms by setting a threshold for broadcast
traffic for each port. Any broadcast packets exceeding the specified threshold will then be
dropped.
Storm Control Configuration
There are three types of traffic which can be rate limited: broadcast, multicast and flooded
Unicast.
Enable Rate Limit: Click the check box and the rate to enable storm control.
Rate (number of frames per second): The Rate field is set by a single drop-down list. The
same threshold is applied to every port on the switch. When the threshold is exceeded,
30
packets are dropped, regardless of the flow-control settings.
ICMP Rate: This can keep you from continuously pinging the switch and wasting the CPU
resource.
Learn Frame Rate: By default, the switch performs wire-speed learning on all ports.
However, if some kind of unknown source MAC is classified as a “learn frame,” it is
redirected to the CPU. These packets will be filtered after enabling this command.
Broadcast: Broadcast traffic.
Multicast: Unknown Multicast Traffic. Before IGMP Snooping is enabled, all the multicast is
flooded and will be filtered by this command.
Flooded Unicast Rate: Any source MAC not yet recognized by the switch is considered
unknown unicast. This command can help limit such traffic.
31

4.2.4 RSTP Status
RSTP VLAN Bridge Overview
Hello Time: Interval (in seconds) at which the root device transmits a configuration
message.
Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports (except for
designated ports) should receive configuration messages at regular intervals. Any port that
ages out STA information (provided in the last configuration message) becomes the
designated port for the attached LAN. If it is a root port, a new root port is selected from
among the device ports attached to the network.
Fwd Delay: The maximum time (in seconds) the root device will wait before changing
states (i.e., discarding to learning to forwarding). This delay is required because every
device must receive information about topology changes before it starts to forward frames.
In addition, each port needs time to listen for conflicting information that would make it
return to a discarding state; otherwise, temporary data loops might result.
Topology: Indicates if Spanning Tree topology is steady or undergoing reconfiguration.
(The time required for reconfiguration is extremely short, so no values other that “steady”
state are likely to be seen in this field.)
Root ID: The priority and MAC address of the device in the Spanning Tree that this switch
has accepted as the root device, and the port connected to the root device.
RSTP Port Status
Port/Group: The number of a port or the ID of a static trunk.
Path Cost: The cost for a packet to travel from this port to the root in the current Spanning
Tree configuration. The slower the media, the higher the cost.
Edge Port: Shows if this port is functioning as an edge port, either through manual
selection (see the RSTP Port Configuration table) or auto-detection. Note that if the switch
detects another bridge connected to this port, the manual setting for Edge Port will be
overridden, and the port will instead function as a point-to-point connection.
P2P Port: Shows if this port is functioning as a Point-to-Point connection to exactly one
34
other bridge. The switch can automatically determine if the interface is attached to a point-
to-point link or to shared media. If shared media is detected, the switch will assume that it
is connected to two or more bridges.
Protocol: Shows the Spanning Tree protocol functioning on this port, either RSTP or STP
(that is, STP-compatible mode).
4.2.4 IGMP Status
IGMP Status
IGMP Status shows the IGMP Snooping statistics for the whole switch.
VLAN ID: VLAN ID number.
Querier: Shows whether Querying is enabled.
Queries transmitted: Shows the number of transmitted Query packets.
Queries received: Shows the number of received Query packets.
v1 Reports: Shows the number of received v1 Report packets.
v2 Reports: Shows the number of received v2 Report packets.
v3 Reports: Shows the number of received v2 Report packets.
v3 Leave: Shows the number of v3 leave packets received.

4.2.5 VeriPHY
VeriPHY Cable Diagnostics
You can perform cable diagnostics for all ports or selected ports to diagnose any cable faults
(short, open etc.) and feedback a distance to the fault.
Cable Diagnostics: Cable diagnostics is performed on a per-port basis. Select the port
number from the drop-down list. Click Apply to start the test.
Cable Status: Shows the cable length and operating conditions and isolates a variety of
common faults that can occur on Cat5 twisted pair cabling.
36
4.2.6 Ping
This command sends ICMP echo request packets to another node on the network.
Ping Parameters
Target IP Address: IP address of the host.
Count: Number of packets to send. (Range: 1-20)
Time Out: Sets the time period the host will be pinged.
Use the ping command to see if another site on the network can be reached.
The following are some results of the ping command:
Normal response: The normal response occurs in 1 to 10 seconds, depending on network
traffic.
Destination does not respond: If the host does not respond, a “timeout” appears in 10
seconds.
Destination unreachable: The gateway for this destination indicates that the destination is
unreachable.
Network or host unreachable: The gateway found no corresponding entry in the route
table.
Press <Esc> to stop pinging.

4.3 Maintenance
4.3.1 Warm Restart
Click Yes to restart the switch. The reset will be complete when the power lights stop blinking.
4.3.2 Factory Default
Forces the switch to restore the original factory settings. To reset the switch, select “Reset to Factory
Defaults” from the drop-down list and click Apply. The LAN IP Address, Subnet Mask and Gateway IP
Address will be reset to their factory settings.
If you forget the password, you can press the Reset button on the front panel for 5 seconds. Then the
system will be reset to the default configuration.
4.3.3 Software Upload
Select “Upgrade Firmware” from the Tools drop-down list then click on Browse to select the firmware file.
Click Apply to upgrade the selected switch firmware file.
Figure: Browse and Upload new software.
38
The “Software successfully loaded” message allows you to activate the new software.
After you click Yes, the following message displays.
39
4.3.4 Configuration File Transfer
Configuration File Transfer allows you to save the switch’s current configuration or restore a previously
saved configuration back to the device. Configuration files can be saved to any location on the Web
management station. Click Browse to choose a file location on the Web management station or to find a
saved configuration file. Click Upload to save a configuration or Download to restore a configuration.
4.3.5 Logout
The administrator has write access for all parameters governing the onboard agent. You should therefore
assign a new administrator password as soon as possible, and store it in a safe place.
