User Manual English
1.0 Introduction
Thank you for purchasing the LINDY 8 Port Gigabit Smart Switch with 2 shared mini GBIC ports.
This high-performance Layer 2 network switch is ideal for use in either the home or the office
All of its ports are capable of 10, 100 or 1000Mbps auto-negotiation, while the 10/100/1000Mbps
auto-sensing ability provides the easiest, most hassle-free way to migrate from a Fast Ethernet to a
Gigabit Ethernet network.
This switch delivers a dedicated 10/100/1000Mbps connection to every attached client with no
bandwidth congestion issues. It also supports an auto MDI/MDI-X function, which means that each
port can be used to connect to another switch or hub without the need for crossover cables!
Store-and-forward architecture is used by the switch to filter and forward data after each packet is
received and examined to be free of errors. All of the ports support full and half-duplex operation
which doubles the network bandwidth and allows the simultaneous transmission and reception of
frames without causing collisions.
The switch provides 9KB Jumbo frame support which can improve network performance by
allowing more data to be sent per transmitted frame.

3.0 Managing the switch
The switch can be managed through the RS232 port or in web mode through the Ethernet port.
3.1 Web mode default setting:
Default IP Address: 192.168.223.100
Default IP mask: 255.255.255.0

User Manual English
Default gateway: 192.168.223.254
Default Password: “admin”
3.2 Terminal mode default setting:
Baud rate: 115,200
Attribute: 8, None, 1, None
Default Password: “admin”
Once the terminal has connected follow the instructions below:
Press “?” to find the root operation page, then choose the command you require by
typing in lower case
When you enter the command page, press “?” again to find the command parameters
and the format. For more information type “command ?” to get an explanation of the
command parameters
Type “u” or “/” to go back to previous page
4.0 Web Management
When your login has been successfully validated, the switch’s home page will appear. The left part
of the page provides the function menus and the right part provides the individual configuration or
system parameters values. The function manuals are divided into three categories, they are
Configuration, Monitoring and Maintenance, these are shown below:

User Manual English
5.0 Configurations
5.1 System Information
The system configuration screen below shows the details and the status of the switch.
If any changes are made you must choose “Apply” for the changes to take effect.
Pressing the “Refresh” button will update the status of the system information
5.2 DHCP
By default DHCP is turned off, so a Default IP or user defined IP address is used
when the switch is turned on. If the switch needs an IP assigned from a DHCP server,
then tick the “DHCP Enabled” box and click on “Apply”. Note: if you are in web page
mode, connection to the switch will be lost. You will need to log back into the
system configuration using the new IP address provided by the DHCP Server.

User Manual English
5.3 Relocate HTTP port number
The default port number of the HTTP command is 80, unauthorised users may
access the switch if they know the IP address. You may set the HTTP port number to
any other value, from 1024 to 65535. Note: once the HTTP port number has been
changed you will lose connection to the switch. To access the switch again use the
following address replacing it with the new port number
http://192.168.223.100:port_value
5.4 Tag VLAN management group (CPU port)
The default VLAN ID group will be VID=1 for all ports. This is to allow the ports to
communicate with each other and also allow you access to the Web Management via
any port when powering the switch on. The web management console can only be
accessed by ports on the VID=1 ID group. To access the Web management console
through other ID groups, go to the system configuration page and select Tag VLAN
Management group 10 and press apply. Now move the RJ-45 (web management
port) from port 1 to the port selected. If you do not know which port has been selected
to host the web management console you will need to “reset” the switch. This can be
done by pressing the reset button for a few seconds. The switch will then return to
default settings, IP Address 192.168.223.100 all ports VID=1
5.5 Port Configuration
The port status page shows the current status of all 8 ports. You can set the link
mode speed, enable or disable flow control and set the jumbo frame size. Note: the
Framesize for all ports can only be set to the same value. An example diagram is
shown below:

User Manual English
Select the changes you want to apply: Eg. If you choose port 1 to have Flow Control
enabled, tick the box and then press “Apply”, the screen below will then appear upon
refresh. An example diagram is shown below:
5.6 Port-based VLAN
Port-based VLAN groups ports by group ID which mean ports on different VLANs
(different IDs) can’t communicate with each other. The default group ID is 1, before
setting another port-based VLAN you must set up a VLAN ID group. This new group
will appear in the Port-based VLAN configuration table. Note: Only member ports in
group ID 1 will be able to access other ports on the same group. An example
diagram is shown below:

User Manual English
Choose and click the ports you want to group, for example, choose port 1, port 2 and
set their group ID 2, then press “Apply”. An example diagram is shown below:
5.7 Tag-based VLAN
Tag-based VLAN allows you to assign a tag-value for each port. The same as port-
based VLAN, ports on different Tag-based VLANs (different IDs) can’t communicate
with each other. The default Tag-based VLAN ID is 1 (VLAN ID=1), another Tag-
based VLAN can be created using numbers from 1 ~ 4094. Note: Tag-based VLAN
members are not only valid within the same device but can also cross devices
as long as they are the same VLAN ID. You can only manage the switch if one
of the VLAN groups are in the VLAN ID of the CPU port. An example diagram is
shown below:

User Manual English
The default VLAN ID group for all ports is VID=1, this is to allow any port to be used
for web management communication with the CPU.
If you wish to isolate ports on a separate VLAN, then you must delete the ports from
VLAN=1 and create another VLAN ID. For example, below we have added ports 7 &
8 to VLAN ID=10 and ports 5 & 6 to VLAN ID=20.
After these changes, you can perform web management on any of the 4 ports on
VID=1. To perform web management on a port in another VLAN you must go to the
system configuration page and select Tag VLAN management group. Once you apply
the changes you must move the RJ-45 connection from port 1 to the port selected.
If you are not sure what port the CPU is active on then you can either:
1. Check for a password through the console port and the configuration of the IP
2. Reset the unit to factory default settings by holding in the reset button for five
seconds

User Manual English
When assigning a tag VLAN, some parameters must be assigned for the tag VLAN
application, here are some definitions of titles when entering the “Port Config”:
VLAN Aware mode:
Enable: When you enable the Tag-VLAN function, you may enable VLAN Aware
mode associated with this port. Ingress and egress frames will be handled according
to the following parameters’ setting
Disable: By default VLAN Aware mode is disabled
Ingress filtering:
Enable: Check the ingress frame VLAN ID. The Ingress frame will be dropped if this
frame's VID is not the same as the VID of the ingress port which belongs to a member
of a VLAN group
Disable: The Ingress frame will be flooded if the VID is not the same
3. Accept Packet Type:
ALL: Accept all ingress frames
Tagged only: Only accept ingress frames with VLAN tag
4. Port VID:
Set Port VID = value (1 ~ 4096), then untagged ingress frames will bear this value as
its VID. Usually this port is connected to an un-tagged device (legacy device), then
this frame becomes a tagged frame. This will allow it to be handled inside the switch
as a member of same VID group
5. Egress Tag enable
When Egress Tag is enabled, the tag will be added into egress frames and then sent
out to the device that supports tagged-VLAN. When this is disabled, a tag will not be
added into egress.

5.8 Port Trunking
The default diagram is shown below, and up to 4 groups are provided:
Choose and click the trunk ports you want to group, for example, choose port 1, port
2 into group 1, then press “Apply”. An example diagram is shown below:
5.9 Port Mirroring
Choose and click the ports you want to monitor, for example, mirror port 2 with port 5.
then press “Apply”. An example diagram is shown below:

User Manual English
5.10 Quality of Service
There are 8 priority levels (0 – 7) each port can be mapped to one of 4 classes (Low,
Normal, Medium and High) this can be done in QoS control.
There are 3 QoS Modes: Port-based, 802.1P and DSCP. The frames are sent by the
priority and Queue Mode settings. Strict Mode means the highest priority setting gets
first service to send frames. The lower priority frames must wait until all other higher
priority frames are sent. An example diagram is shown below with Strict Queue Mode:
When you choose 802.1P priority, the frames have VLAN Tag inside the switch. The
priority in the Tagged frame (2 bytes Tag in total) must be set by the application
program.

User Manual English
5.11 Storm Control
A default diagram is shown below,
Choose the type of storm you want to control, for example, if you choose Broadcast
storm with 3,964 fps as the upper limit, once this frame rate is reached the port will be
disabled. An example diagram is shown below:

User Manual English
5.12 LACP
Similar to static port trunking, LACP provides another way to dynamically aggregate a
port to a group (trunk) according to IEEE 802.3ad. Once the protocol is enabled, the
ports to be trunked by LACP will be executed automatically after pressing “apply”. An
example diagram is shown below:
Protocol Enabled: To enable/disable LACP protocol for a port.
Key Value: A number (1~255) to identify the LACP group for a port. All member ports
in a LACP group have the same key values. A Key number will be automatically
generated if the “auto” value is set
Choose and click the trunk ports you want to group. For example, select port 5,6,7
and port 8 to group into an LACP group with key value “auto”. Then press “Apply” to
activate the setting. An example diagram is shown below:

User Manual English
5.13 RSTP
The Spanning-Tree Protocol (STP) is the IEEE 802.1d standardised method for
avoiding loops in switched networks. Enable STP to ensure that only one path at a
time is active between any two nodes on the network.
The Rapid-Spanning-Tree-Protocol (RSTP) is a more advanced protocol than STP
according to the IEEE 802.1w standard. RSTP can shorten spanning tree convergent
time while network topology is changed. An example diagram is shown below:
System Configuration
System Priority: A value to identify the root bridge. The bridge with lowest value has
the highest priority and is selected as the root. 16 numbers are provided in this field
from 0 to 61140 in increments of 4096.
Hello Time: The number of seconds among the transmission of Spanning-Tree
Protocol configuration messages. Enter a number 1 through 10. (default is 2)
Max Age: The number of seconds the bridge waits without receiving Spanning-Tree

User Manual English
Protocol configuration messages before attempting a reconfiguration. Enter a number
between 6 & 40. (default is 20)
Forward Delay: The number of seconds a port waits before changing from Spanning-
Tree Protocol learning and listening state to the forwarding state. Enter a number
between 4 & 30. (default is 15)
Force Version: Normal: use RSTP/Compatible: compatible with the old STP protocol
Port Configuration
Aggregations: Enable/Disable the RSTP protocol on aggregation links
Protocol Enabled: Enable/Disable the RSTP protocol per port basis
Edge: Enable/Disable to expect a port to be an edge port (an end station) or a link to
another STP device
Path Cost: A value on a port the switch uses to determine which port are the
forwarding ports. The lowest number is forwarding ports. The value can be set from 1
to 200000000 or “auto” to be automatically generated
5.14 IGMP
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IGMP can manage the multicast traffic if the members
(switches, router or other network devices) of the group support IGMP. This switch
provides IGMP snooping feature to detect IGMP queries, report packets and
manages the IP multicast traffic through the switch. This feature can limit the
forwarding multicast frames only to those ports that are a member of multicast group.
Only IPv4 IGMP frames are recognized for this system.
IGMP Enabled: Globally enable/disable IGMP snooping function
Router Ports: The port that is usually with source of multicast traffic stream
Unregistered IPMC Flooding Enabled: To set the forwarding option for unregistered
(not joined) IP multicast traffic.
Enabled: to flood frames to every port;
Disable: to forward frames only to those IGMP member ports
Two options can be set for each existing group:
IGMP Snooping Enabled: To enable/disable snooping IGMP frames
IGMP Querying Enabled: To enable/disable sending IGMP querying frames. In one

User Manual English
Ethernet section, there is only one Querier, and this is usually the router
For example, video traffic comes from port 8 which is connected to a router, and port
3,4,5 are Connected to IGMP member, then the configuration may be set as below
5.15 802.1x
A default diagram is shown below, user must contact the manager of RADIUS server,
and then get the IP, UDP port number (usually fixed at 1812) and secret password to
operate 802.1X.
Admin Mode:
Auto: The client will be authorised by authentication process
Force Authorised: The client will be authorized anyway
Force Unauthorised: The client won’t be authorized anyway
Action: Execute the command on single port or all ports when click
Re-authenticate: Authorized again on that port
Force Reinitialize: Force the port initialization
Statistic: See statistic frames
