Congratulations on your purchase of this Fast/Gigabit Ethernet
Management Switch. This high performance management
switch provides Ethernet ports to segment network traffics,
extend Ethernet connection distance, and convert data packets
between different transmission speeds.
This switch utilizes stored-and-forward switching architecture
that filters and forwards data after the complete data packet is
received and examined to be free of errors. With one set of
status LEDs for each individual port, the switch operation status
can be easily monitored.
All the Fast Ethernet ports support both Full and Half duplex mode which are able to provide up to 200Mbps(2000Mbps for
Gigabit Ports) of bandwidth to the connected devices, with
auto-negotiation providing the capability to connect to
100/10Mbps(1000/100/10Mbps for Gigabit ports) network devices. It also supports backpressure and IEEE 802.3x
advanced flow control capabilities that can reduce congestion
and prevent packet loss.
And it offers advance features:
SNMP/Web-based Management: Provides a web browser
to manage and monitor the switch.
Bandwidth Control: Input and output rate control.
VLAN: Port-based and Tag-based VLAN allow you to set
virtual LANs within your network
Trunking: Reduce the bottleneck between switches
QoS: Two priority queues per port allow you to define
which port has higher priority.
802.1X: This switch supports port-based authentication
protocol, IEEE 802.1X.

4.5 Trunking
The Link Aggregation Control Protocol (LACP) provides a
standardized means for exchanging information between Partner
Systems on a link to allow their Link Aggregation Control
instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, move the link to
that Link Aggregation Group, and enable its transmission and
reception functions in an orderly manner. In conclusion, Link
aggregation lets you group up to eight consecutive ports into a
single dedicated connection. This feature can expand bandwidth
to a device on the network. LACP operation requires full-duplex mode, more detail information refers to IEEE
802.3ad.
4.5.1 Aggregator setting
System Priority: A value used to identify the active LACP. The
switch with the lowest value has the highest priority and is
selected as the active LACP.
1.Group ID: There are seven trunk groups to provided
configure. Choose the "group id" and click "Get".
2.LACP: If enable, the group is LACP static trunking group. If
25
disable, the group is local static trunking group.
All ports support LACP dynamic trunking group. If connecting
to the device that also supports LACP, the LACP dynamic
trunking group will be created automatically.
3. Work ports: Allow max four ports can be aggregated at the
same time. If LACP static trunking group, the exceed ports is
standby and able to aggregate if work ports fail. If local static
trunking group, the number must be as same as the group
member ports.
4 Select the ports to join the trunking group. Allow max four
ports can be aggregated at the same time.
5. If LACP enable, you can configure LACP Active/Passive
status in each ports on State Activity page.
6. Click Apply.
4.5.2 Aggregator Information
When you are setting LACP aggregator, you can see relation
information here.
1. This page is no group active. LACP don’t working.
2. This page is Static Trunking group.
26
4.5.3 State Activity
Active (selected): The port automatically sends LACP protocol
packets.
Passive (not selected): The port does not automatically sends
LACP protocol packets, and responds only if it receives LACP
protocol packets from the opposite device.
1. A link having either two active LACP ports or one active port
can perform dynamic LACP trunking. A link has two passive
LACP ports will not perform dynamic LACP trunking because
both ports are waiting for LACP protocol packets from the
opposite device.
2. If you are active LACP actor, when you select trunking port,
the active status will be created automatically.
27
4.6 Filter Database
4.6.1 IGMP Snooping
This switch supports IP multicast, you can enable IGMP
protocol on web management’s switch settings advanced page,
then display the IGMP snooping information in this page, you
can view difference multicast group ,VID and member port here,
IP multicast addresses range from 224.0.0.0 through
239.255.255.255.
The Internet Group Management Protocol (IGMP) is an
internal protocol of the Internet Protocol (IP) suite. IP manages
multicast traffic by using switches, routers, and hosts that
support IGMP. Enabling IGMP allows the ports to detect IGMP
queries and report packets and manage IP multicast traffic
through the switch.
4.6.2 Static MAC Address
When you add a static MAC address, it remains in the switch's
address table, regardless of whether the device is physically
connected to the switch or not. This saves the switch from
having to re-learn a device's MAC address when the
disconnected or powered-off device is active on the network
again.
28
Steps to add Static MAC Address:
1. From the main menu, click administrator->Filter Database
->Static MAC Address.
2. In the MAC address box, enter the MAC address to and from
which the port should permanently forward traffic, regardless of
the device’s network activity.
4. In the Port Number box, enter a port number.
5. If tag-based (IEEE 802.1Q) VLANs are set up on the switch,
static addresses are associated with individual VLANs. Type the
VID (tag-based VLANs) to associate with the MAC address.
6. Click add.
29
4.6.3 MAC Filtering
MAC address filtering allows the switch to drop unwanted
traffic. Traffic is filtered based on the destination addresses.
Steps to specify a MAC address to filter:
1.In the MAC Address box, enter the MAC address that wants to
filter.
2. If tag-based (802.1Q) VLAN are set up on the switch, in the
VLAN ID box, type the VID to associate with the MAC address.
3. Click the Add.
4. Choose the MAC address that you want to delete and then
click the Delete can delete it.
