Step 1: Place the Switch on a smooth surface or fasten the mounting brackets with the provided screws in a standard 19” rack
Step 2: Connect the DC jack of AC adapter to the DC inlet socket of Switch and the other end into the local power source outlet
Step 3: Connect hub or PC to one port of the Switch using Category 3/4/5 UTP/STP cabling
Step 4: Connect another hub or PC to the other port of the management Switch by following the same process as described in Step3.
Notice:
Cable distance for Switch
The cable distance between Ethernet Switch and hub/PC should not exceed 100 meter, fiber cable distance shall not exceed 220 meter.
Make sure the wiring is correct
It can be used Category 3/4/5 cable in 10 Mbps operation. To reliably operate your network at 100Mbps, you must use an Unshielded Twisted-Pair (UTP) Category 5 cable, or better Data Grade cabling. While a Category 3 or 4 cable may initially seem to work, it will soon cause data loss. Or 1000Base-SX multi-mode 62.5/125μm fiber optic cable for fiber connector application. All kinds of hub/PC can connect to 16/24 Port 10/100/1000Mbps Switch by using straight-through or crossover wires.
Connecting to Network Backbone or Server
Connect to the Gigabit Ethernet ports with Category 5 copper cable or fiber optic cable for uplinking to a network backbone or network server. These ports operate at 1000Mbps in full-duplex mode. A valid connection is indicated when the Link LED is light

Step 1: Type in the password and click “Log on!”. The default password is “password”.
After logging in to the Management system, the Main Page will display as shown below. The image of the management switch is shown on the upper right window. The status of each switch port (i.e. link, speed and duplex mode) can e seen clearly from the LED displays on the image. The lower right window is used to display the web pages of versatile configuration and operations.
Configuration of Ports
This section allows you to have an easy access in configuring the ports of the management switch. Notice that the “Link state” option indicates “Up”. This shows that the port is connected to the network. It can either be in “Up” (Connected) or “Down” (No connection) state.
Description of Parameters
You can choose a port either by clicking on the picture or by selecting it at the “Choose Port” field.
Speed/ Duplex is to select the operation mode of chosen port. The options are as:
‘Auto’: Auto negotiation
‘10Mbps HD’: 10 Base-T Half/ Duplex
‘10Mpbs FD’: 10Base-T Full Duplex
‘100Mpbs HD’: 100Base-TX Half Duplex
‘100Mbps FD’: 100Base-TX Full Duplex
This function sets broadcast limit to the desired rate for the specified port. It controls the reception of broadcasting packets. The ranging for Broadcast rate limit varies from 0% to 100%. The higher the rate is, the more data can pass through the traffic. Rate is the percent of the traffic to allow before throttling. I.e. if you want the switch to allow a maximum of 10%, the broadcast traffic on a given link will let 10% of the data to pass in.
In a tagged VLAN application, you can specify the VLAN priority to expedite the VLAN traffic. There are 8 levels of priority, namely ‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’ and ‘7’ in ascending priority.
VLAN ID is the sequence number of a VLAN. In this case, the management switch has 32 VLANs to specify and therefore the VLAN ID is from 1 to 32. The setting of the VLAN ID depends on ‘Belongs to VLANs’ option.
Port state is for the enabling or disabling the switch operation of the chosen port. If it is ‘enabled’, the chosen port will receive and forward the packets, and learns the respective source MAC Addresses. If it is ‘disable’, the chosen port will not receive or forward any packets or learn source MAC Addresses.
It should be noted that if the CPU port (i.e. the switch port connected to the management port) is disabled, the communication link between user and proceed further. So, disabling the CPU port will be rejected automatically by the management system.
This feature reports the Flow Control setting of the port. Enabling the Flow Control function allows Half and Full Duplex mode. If Flow Control function is ‘Disabled’, both Half and Full Duplex mode will be disabled.
Port Setting Procedure
Step 1: Click on the image to select a port or select from the ‘Choose Port’ field
Step 2: Select Speed/ Duplex Mode and choose Port Lock field
Step 3: Enter the rate for Broadcast Rate Limit field and set Current VLAN ID
Step 4: Choose either ‘ Enabled’ or ‘Disabled’ for both Port State and Flow Control field. Set the Port Priority
Step 5: Click on “Apply” button to make the configuration effective. Hit the “Save” button if you are satisfied with the setting.
Setting Up of Port Security
Of all 26 ports, some of the port may need to assign to the specific port. In order to fulfill this act, MAC Address should be added to that particular port. This is to ban other users from using the static port. A port can accommodate up to 20 MAC Addresses.
Setting Up Procedures
Step 1: Select the port that you want to add in the MAC Address
Step 2: Key in the MAC Address in the field provided, e.g. 00-80-40-E8-85-12, and click “Add” button
The system will then add in the New MAC Address into the listing on the right side of the screen.
Delete MAC Address
If you want to delete MAC Address/es, simply follow the procedures shown below:
For deleting individual MAC Address
Step 1: Select a MAC Address and clink on “Del→” button.
The system will prompt you to confirm your action:
Step 2: Choose “OK” button to confirm.
The particular MAC Address will be successfully deleted!
For deleting ALL MAC Addresses
Step 1: Click on “Delete All” button and the system will again prompt you the message as shown as above.
Step 2: Choose “OK” button to confirm.
All MAC Addresses will be deleted immediately!
Setting Up of Mirror Port
Using Mirror Port to Monitor Traffic
This function allows you to set up a ‘mirror’ port of any specified port/s or VLAN, such that you can monitor the traffics of the monitored port/s or VLAN without intervening them. In effect, the traffics on the monitored port/s VLAN are replicated on the mirror port that you can use a protocol analyzer to analyze the traffic for specific problem.
Setup Procedures
Step 1: Select one Mirror Port.
Step 2: Click on the dashed line ‘-‘ on that particular port if you wan to select it as a Mirrored Member (T).
Step 3: Hit on “Apply” button after you are satisfied with the setup. Click “Save” button to update the latest configuration.
Configuration of VLAN
The management switch supports Virtual LAN, which logically group the connection into VLANs for traffic isolation and security purposes. Both tagged and untagged based VLAN are supported with a total maximum of 31 groups. Each VLAN group only forwards traffic within its member ports. For tagged VLAN, each port can be a member of more than one VLAN group and it also supports priority with eight levels. There is also provision for creating a tagged VLAN shich sport a connection with a legacy untagged VLAN. The VLAN configuration feature also allows you to build, delete and view tagged/ untagged VLAN groups and setting priority for tagged VLANs. The range of VID starts from 2 to 4094, as VID 001 is the default for Group 1.
Setup Procedures
Step 1: Decide which Group you want to set for monitoring using mirror port. Click status column for that particular group and key in the VLAN ID.
Step 2: Next, click on the dashed line’-‘ to select either “t” for Tagged or “U” for Untagged.
Step 3: Hit on “Apply” button after you satisfied with the setup. Click “Save” button to update the latest configuration.
Trunking Configuration
Port Trunking is the ability to group together several switch ports to increase the bandwidth between the management switch and other switch. This is an inexpensive method to increase through put between switches (or to servers). We define the Port Trunking as the ability to group a set of ports into a single logical link. The port trunk acts as signle link between switches. It doesnot create a loop even though it is physically connected as such.
Port Trunking Setup Procedures
Step 1: You can choose up to 4 groups for Trunking by selecting ‘-‘ as “T”
Step 2: Click on “Apply” button to make the configuration effective.
Step 3: Click “Save” button to save the latest setting.
Note: If you select more than 4 ports for trunking, the following error message will appear:
Click “OK” button and select the ports again.
Advanced Configuration
STP Bridge
This page lets you to have a clearer view in Spanning Tree parameters and configure individual switch ports to participate in the Spanning Tree algorithm.
Description of Parameters
When STP is enabled, it will dynamically detect network looping owing to mis-configuration of the network topology. The redundant connectors will be disabled to avoid looping of packets. Looping would often result in flooding of broadcast packets, halting the normal traffic.
The priority of the switch is currently acting as the root. The bridge with the lowest value has the highest Spanning Tree priority level and is related as the root.
The Hello time of the Spanning Tree field shows the number of seconds between the transmissions of Spanning Tree protocol configuration messages.
The Forward Delay field shows the number of seconds a port waits before changing from its Spanning Tree Protocol learning and listening states to the forwarding state. This wait is necessary so that other switches on the network ensure no loop is formed before they allow other port to forward packets.
The maximum age time of the Spanning Tree shows the number of seconds the ridge waits without receiving Spanning Tree Protocol configuration message before attempting a reconfiguration.
Setup Procedures
Step 1: Select Spanning Tree state option, either to enable or disable it.
Step 2: Set Root Priority from 0 s – 65535 s, and Hello Time from 1 s – 10 s.
Step 3: Key in the Forward Delay Time, Maximum Age and Hold Time.
Step 4: Click “Apply” button and save it if everything is OK.
Note: The screen is divided into two sections. Current Spanning Tree Root section displays the read-only Spanning Tree settings for the current root switch and the parameters this switch is to use when it becomes the root switch.
STP Port
This section helps you to change the port-specific parameters.
Description of Parameters
This option shows the port of the bridge that connects to the root bridge.
This option sets the Spanning Tree path cost for this port. A lower path cost represents higheTree. You can set “r transmission speed. Assign the lowest path cost to the port you want used by the Spanning Tree. You can set “Path Cost” to any of the value, starting from 1 to 65535.
Sets the port’s priority, starting from 0 to 65535, in the Spanning Tree algorithm. The higher the number has a higher priority.
Setup Procedures
Step 1: Select any one of the ports, from 1 to 26, to connect to the root bridge.
Step 2: Key in the value for Path Cost.
Step 3: Set the priority level.
Aging Control
Aging Control is for the aging of address entries in the switch’s forwarding table. If the aging control is enabled, a learned address entry (not included the static entry) will be removed from the forwarding table if there is no update within a pre-determined period (1 ~ 128 seconds). It is useful because the resource of the forwarding table is limited. Enabling the aging control will not influence packets forwarding, for that the packet is forwarded to all other ports when the destination MAC address cannot to found in the forwarding table. If the aging control is disabled, all address entries will no be removes.
Aging Control Configuration Procedures
Step 1: Select “Enable” from the Aging Control option.
Step 2: Enter an integer in the entry, choosing from the range of 1 to 128, if the aging control is enabled. If the aging control is disabled, this stop can be skipped.
Searching Host using IP Address
Host Search is for searching a host by IP address on the whole switch, and getting the port umber to switch the host is connected. It is useful while configuring the VLAN. With this function, you can easily detect the port at which a host is connected to and have an idea about which ports should e included in a VLAN.
Host Searching Procedures
Step 1: Enter the IP Address of the host.
Step 2: Click on “Search” button.
If the system can not find the Host Address the following GUI will appear:
MAC Address Search
This feature helps to look for the particular MAC Address sated in the field, which provides a useful way while configuring the VLAN. The system will search through the device for the port’s ownership of that particular PC.
MAC Address Search Procedures
Step 1: Enter MAC Address in the field provided.
Step 2: Click on “Search” button.
If MAC Address was found by the system, the result will appear as:
But, if the system cannot find any matching MAC Address, the following search result will appear:
Using System Tools
Define System Configuration
This is an easy access in configuring the system. You can configure IP address or Subnet Mask of the management board in the management switch. It is likely that several VLANs are on the single switch and each VLAN can be regarded as an independent network, so their network addresses may be different.

Application on Virtual LAN
Untagged VLAN
In an untagged VLAN application, you can assign a group of ports within a switch as members of specific VLAN. Data traffic would be confirmed within the member ports. In this way, devices connected with the switch can be partitioned into distinct groups each corresponds to a different VLAN. The partition (VLAN) can be expanded when two untagged VLANs are connected together through their member ports. No two VLANs can be overlapped. Each VLAN is separate from the rest. It provides a simple means to implement a secure and managed network.
There are two VLANs, A and B in the network. Notice that separate links are required between switches to join the two VLANs.
Tagged VLAN
Shared Uplink Conntection
In a tagged VLAN application, you still can assign specific ports within a switch to be a VLAN group. In addition, the data transferred within the VLAN group is tagged with an ID as specified with the 802.3Q Tagged VLAN standard It allows the VLAN information to be carried alogn as the data flow from switch to switch. It also allows a port to carry multiple VLANs data stream. It is more flexible and scalable than the untagged VLAN application. However, all networking devices have to support the 802.3Q Tagged VLAN standard for VLAN Tagging system to work.
Two tagged VLANs are created in the physical network. VLAN 2 consists of Server 1, Workstation 1, 2 and 3. VLAN 3 consists of Server 2, Workstation 4 and 5. The connection with port 7 of Switch 1 and port 1 of Switch 2 transfer data for both VLAN 2 and 3 simultaneously and separately.
Tagged VLAN with legacy (untagged) VLAN support
In most scenarios, there are legacy-networking devices that do not support 802.3Q Tagged VLAN. To accommodate such devices, tagged VLANs are normally inapplicable. However, the management switch has provision for legacy device support. It allows an untagged VLAN or device to join the tagged VLAN while work together as in a tagged VLAN application.
Legacy Device- VLAN Support
The example below shows the switch in a backbone application. Workstation 1 is a legacy device, which do not support VLAN tagging. There is also an untagged VLAN connecting the hub to port 7 of the switch. Other devices would support 802.3Q Tagged VLAN. The commands build two tagged VLANs (Workstation on Port 2) and an untagged VLAN (hub on Port 7). The switch would tag and un-tag the data such that data flowing into Port 7 would be tagged with a VLAN ID of ‘3’ while data flow out of it would be untagged that the legacy VLAN would recognize it.
Note: The VLAN configuration shown above would be impossible to implement with untagged VLAN.
Legacy Devices Support
With the legacy support, the untagged example (page ), now can be configured as two tagged VLANs with two ports less. The two connections now share one connection between the two switches. The tagged VLAN effectively connects all untagged devices.
Command Reference
Command Line Basic
The management switch provides a command line interface via the console connection for user to view and configure various features of the switch. You may globally or individually setup each port for your desired operation. Advanced features like ‘VLAN’ and ‘trunking’ etc.
Access Level Categories
Each command is assigned with an access level so that only user logins with the corresponding access level can access the command.
There are two access levels namely ‘operator’ and ‘administrator’ level.
‘Operator’ access level allows users to view the switch status. It is the default access mode on power up.
‘Administrator’ access level allows users to configure various parameter of the switch. It is for IT personnel who are responsible for setup or maintenance of network system. User can login to ‘administrator’ (via the ‘login_admin’ command) and logout (via the logout command) afterward.
You would know if you are in ‘Operator’ or ‘Administrator’ access level by th3e greeting command prompt. In ‘Administrator’ access level, you would see the ‘ADMIN’ wording in the command prompt e.g. ‘ADMIN HOME>’ in the ‘HOME’ page.
Command Navigation
The commands are structured in pages to allow easy access. When the switch is first power up, you are presented with a ‘HOME’ page. It contains commands to navigate down to three ‘BOTTOM’ pages, each containing commands in different categories. User can return to the ‘HOME’ page with the ‘EXIT’ command afterward.
The commands can e categorized as ‘General’, ‘System Management’, ‘Port Management’ and ‘VLAN Management’ commands.
You would know which page you are in by the greeting command prompt. You should get the ‘HOME’, ‘SYSTEM’, ‘PORT’ or ‘VLAN’ wording in the command prompt if you are in respective page.
