3.3.1 System
System configuration is one of the most important configurations in the switch.
Without the proper setting, network manager will not be able to manage or view the
device. The switch supports manual IP address setting. After applying a new IP
address, a new login page will be started automatically. Please login again to
proceed to other configurations.

Parameter description:
zMAC Address:
It is the Ethernet MAC address of the management agent in this switch.
zS/W Version:
The sfotware version of this switch.
zIPAddress:
Users can configure the IP settings and fill in new values. Then, click <Apply>
button to update. Default: 192.168.1.1
zSubnet Mask:
Subnet mask is made for the purpose to get more network address because any
IP device in a network must own its IP address, composed of Network address
and Host address, otherwise can’t communicate with other devices each other.
But unfortunately, the network classes A, B, and C are all too large to fit for
almost all networks, hence, subnet mask is introduced to solve this problem.
Subnet mask uses some bits from host address and makes an IP address
looked Network address, Subnet mask number and host address. It is shown in
the following figure. This reduces the total IP number of a network able to
support, by the amount of 2 power of the bit number of subnet number (2^(bit
number of subnet number)).
11

Subnet mask is used to set the subnet mask value, which should be the same
value as that of the other devices resided in the same network it attaches.
Default: 255.255.255.0
32 bits
Network ID Host ID
Network ID Host ID
Subnet number
zGateway:
Set an IP address for a gateway to handle those packets that do not meet the
routing rules predefined in the device. If a packet does not meet the criteria for
other pre-defined path, it must be forwarded to a default router on a default path.
This means any packet with undefined IP address in the routing table will be
sent to this device unconditionally. Default: 192.168.1.254
zManagement VLAN:
The VLAN group that is allowed to access the WEB-based management
interface.
zUser name:
The login name. (Default: admin)
zPassword:
The login password. (Default: admin)
zSystem Name:
The name of the device.
To save the configuration of the system, click “Apply” to save
Note: After applying a new IP address, a new login page will be started
automatically. Please login again to proceed to other configurations.
3.3.2 Port
Ports Configuration is applied to change the setting of each port. In this
configuration function, you can set/reset the following parameters, Mode, Flow
Control and Max frame.All of them are described in detail below.
12

Parameter description:
zLink:
Shows the link status of each port. The column lights green with the link speed
while there is valid connection on this port.
zMode:
Select a speed for this port. “Auto Speed” enables auto-negotiation. “Disable”
stop the port from functioning.
zFlow Control
There are two modes to choose in flow control, including Enable and Disable. If
flow control is set Enable, both parties can send PAUSE frame to the
transmitting device(s) if the receiving port is too busy to handle. When it is set
Disable, there will be no flow control in the port. It drops the packet if too much to
handle. Default: Enable
zMax Frame length:
To adjust max frame size. The length is 1518 bytes. The Maximum value can be
up to 9600 bytes.
To save the configuration of the system, click “Apply” to save. You can also click
the “Refresh” button to see the latest status of each port.

zPVID setting
When the VLAN-enabled switch receives a tagged packet, the packet will be
sent to the port’s default VLAN according to the PVID (port VLAN ID) of the
receiving port.

zPort:
Port Number 1~16/24
zEgress:
Select “tagged” in the drop list to enable the PVID checking and tag inserting
of one port, and select “untagged” to cancel. For example, if an Egress-tagged
port receives an untagged frame, it will be transmitted as a PVID tagged frame.
For the detail tagging status, please refer to the following table.
Untagged Tagged
Packet Frames In Packet Frames Out Packet Frames In Packet Frames Out
Untagged Untagged Untagged Tagged (PVID)
Tagged Untagged Tagged (VID) Tagged (VID)
Pri-tagged Untagged Pri-tagged Tagged (PVID)
zPVID
Port VLAN ID(1~4094)
zFrame
Tagged: block all un-tagged packets from accessing this port.
ALL: All packets are allowed to access this port.
15

3.3.4 Aggregation/ Trunk Configuration
To set up the Port trunk groups, put the ports number into the sameAggregation
group. There are eight groups to choose. Don’t forget to click the “Apply” to save
the setting.
There are three aggregation modes for you to setup, SMAC, DMAC, and XOR.
SMAC mode selects the path of packets according to source MAC while DMAC
mode selects path according to destination MAC. XOR mode calculates the result of
DMAC and SMAC mode to decide the path of pack
3.3.5 Quality of Service
QoS enhances the communication quality by giving different precedence to
classified packets. This switch provides port-based, tag-based and DSCP QoS
modes:
