4. Management
This page administrator can reboot the system or reset the system to default settings. Users can also
backup or restore device settings, and also upgrade firmware from this page.
System
Reset to default: Administrator can click the button to reset system default.
Reboot system: Administrator can click the button to reboot system.
Configuration
Path: Display path for the restore config file.
Select file: Administrator can click button to find the restore config file in the PC.

5. VLAN
The VLAN function administrator can set IEEE 802.1q Tag Based VLAN or Port Based VLAN. System
default is tag based VLAN.
IEEE 802.1Q VLAN
PVID: Administrator can set Port tag VLAN ID
802.1Q VLAN: Administrator can set tag number for 802.1Q VLAN.
Port-Based VLAN
Administrator can set Group for Port VALN

V2.0b
6. Trunking
The trunking function support 802.3ad (LACP, Link Aggregation Control Protocol)
Link Aggregation Control Protocol (LACP) can aggregate multiple Ethernet ports together to form a
logical aggregation group. To upper layer entities, all the physical links in an aggregation group are a
single logical link.
LACP Global State: Administrator can Enable/Disable the function.
Link Aggregation Algorithm: Administrator can select SA or DA or SA+DA for the MAC Frame.
MAC DA: Destination Address
MAC SA: Source Address
Layer2 Packet Frame : The following example
Preamble
SFD
DA
SA
Ether type
Payload
……..
Link Group Activity: Administrator can select active/passive of the Link Group Activity.
To properly use LACP, the two switches must have one switch enable
“active” function or both enable “active”,
Administrator can’t set
"passive" in the two switch
Link Group Member: If LACP function is enabled, the Link Group member will
auto-display.

V2.0b
7. Mirror
Port mirroring function can mirror Ingress/Egress traffic, the packet can mirror to Destination port
and for analysis
Enable Mirror: Administrator can check to start mirror function
Mirror To: Administrator can mirror traffic to select post.
List: Administrator can selected mirror type by ingress or Egress
8. QoS
Quality of Service (QoS) prioritizes network traffic and manages available bandwidth so that the
most important traffic goes first. QoS is implemented as rules or policies that prioritize packets,
optionally change information in the packet header, and assign them to outbound port queues
based on their priority.
Administrator can select disable service or 802.1p/Port-Based QoS function. The default is Disables
QoS.

V2.0b
Select QoS Type
Disable QoS: Administrator can disable QoS function.
Port-Based QoS: Administrator can use Port-Based mode to traffic management.
IEEE 802.1q QoS: Administrator can use IEEE 802.1q mode to traffic management.
Port-Based QoS:
Administrator can set Queue (weight) QoS by Port.
Queue0 is Low Priority, Queue3 is High Priority.

V2.0b
IEEE 802.1q QoS
Administrator can set Queue (weight) QoS by Tag VLAN.
Queue0 is Low Priority, Queue3 is High Priority.
9. Rate Limiting
The rate limiting function can be configured to limit the rate of traffic received on a particular
interface.
Administrator can to click “Edit” button to set rate limiting for each ports.
Port: Display Port list.
Ingress/ Egress rate: Administrator can set ingress or Egress for rate limiting.

V2.0b
10. Loop Detection / Prevention
Loop detection / Prevention can be used in a network topology to prevent or detect Layer 2 loops
that occur due to misconfigurations.
When occur a loop, Administrator can go to user manual “System” (section 3.) to monitor loop
status, and tick off Loop Unlock for desired ports.
Off: Administrator can disable loop detection or prevention function.
Loop Detection: Administrator can select used loop detection mode to detect network
situation.(2 Port LDE is off by loop Port)
Loop Prevention: Administrator can select used loop Prevention mode to prevent network
looping. When used Loop Prevention function, Administrator can go to close one loop line in
the “3. System” Page.

V2.0b
11. IGMP Snooping
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network
traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and
routers. By listening to these conversations the switch maintains a map of which links need which IP
multicast streams. Multicasts may be filtered from the links which do not need them and thus
controls which ports receive specific multicast traffic.
Administrator can enable “Blocking Unknown Multicast” or IGMP Snooping by port (use static router
port)
Blocking Unknown Multicast: Administrator can start Blocking unknown multicast addresses.
Enable IGMP Snooping: To alleviate the burden of IGMP queries.
When LACP function is enable, the last two port (7 & 8) can’t set to " Static
Router Port ".

V2.0b
12. PoE
The function can monitor PoE used power status / Module Temperature and PoE voltage status.
Administrators can control PoE usage through the per port On/Off option.
POE Global Settings
：
The function can monitor PoE used power status / Module Temperature and PoE voltage
status.
POE Total Power = 65W ( x2 unit Design)
POE MAX LED Power = 92W ( 70% )
