Note: The default IP address of switch is 192.168.2.1. The default subnet mask is 255.255.255.0 (24)
Click "Network Admin" > ''IP'', the screen will show as:
Figure 2-1 IP Configuration Screen
Following is description detail about IP configuration:
Name
Description
VLAN
VLAN for access and management of switch
IPv4 DHCP
-If enable, it means that VLAN port start IPv4 DHCP client, to dynamically get
IPv4 addresses of the switch. Otherwise, it will use switch’s static IP
configuration.
-Fallback (Seconds), means the waiting time for switch to get dynamic IP
address via DHCP. The value of "0" here means never over the time.
-Current Lease, means the IP address get from DHCP
IPv4
-Address: static IPv4 address entered by user.
-Mask Length: static IPv4 subnet mask entered by user.
Click ''Add Interface'' to create a new management for VLAN and IP address. Click ''Save'' to save settings.
Note: The switch has only VLAN1 by default. If the user needs to use another VLAN for switch management,
please first add a VLAN in the VLAN module, and add the relevant port to the VLAN.

2.2 SNTP Configuration
SNTP is an acronym for Simple Network Time Protocol, a network protocol for synchronizing the clocks of
computer systems. You can specify SNTP Servers and set GMT Time zone. The SNTP Configuration screen
will appear after you click "Network Admin" > "SNTP".
Figure 2-2 SNTP Setting Screen
Configuration object and description is:
Object
Description
Mode
Click drop-down menu to select "Enabled" or "Disabled" SNTP.
Enabled: Enable SNTP mode operation. When enabling SNTP mode operation, the
agent forwards and transfers SNTP messages between the clients and the server
when they are not on the same subnet domain.
Disabled: Disable SNTP mode operation.
SNTP Sever
After input SNTP server IP address, SNTP information will be get from that server.
After configuration is set, please click "Save" to save the settings.
2.3 SNMP Configuration
Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of
management information between network devices. It is part of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol suite. SNMP enables network administrators to manage network performance, find
and solve network problems, and plan for network growth.
This switch supports SNMPv1, v2c. Different versions of SNMP provide different security levels for
management stations and network devices.
In SNMP’s v1 and v2c, it uses the "Community String" for user authentication. That string is similar to
password function. The SNMP application of remote user and SNMP of the switch must use the same
community string. SNMP packets of any unauthorized sites will be ignored (discarded).
"Community String" by default for switch’s SNMPv1 and v2c access management is:
1. –allow authentication management station to read MIB objects.
2. –allow authentication management station to read, write and edit MIB objects.
Trap
Used by the agent to asynchronously inform the NMS of some event. These events may be very serious, such
as reboot (someone accidentally turned off switch), or just general information, such as port status change. In
these cases, switch create trap information and send then to receiver or network admin. Typical trap includes
authentication failure, networking changes and cold/hot start trap.

SGX368244M Web Management User’s Manual
MIB
A MIB is a collection of managed objects residing in a virtual information store. Collections of related managed
objects are defined in specific MIB modules. The switch uses the standard MIB-II information management
module. So, MIB object value can be read by any SNMP web-managed software.
2.3.1 SNMP System Configuration
You can enable or disable the SNMP System Configuration. Its screen will appear after you click "Network
Admin" > "SNMP" > "System"

Description
Link
Red color means Link Down, green color means Link Up
Speed
Select the port speed and full / half duplex mode.
"Disabled" means that port is disabled.
"Auto" meaning in full-duplex (FDX) or half-duplex mode (HDX) (1000mbps always in
full-duplex mode) auto negotiate among 10,100,1000Mbps devices. "Auto" setting
allows the port to automatically determine the fastest settings for the device
connected, and to apply these settings.
"1000-X_AMS" means that port is Ethernet/Optical combo port, and optical port is
prioritized.
Other options are 10M HDX, 10M FDX, 100M HDX, 100M FDX, 1000M FDX, 1000-X.
Flow Control
It is a flow control mechanism for a variety of port configurations. Full-duplex ports
use 802.3x flow control, half-duplex ports use backpressure flow control. It is disabled
by default.
Check to enable flow control.
Maximum Frame
Size
It is used to set the maximum frame size for Ethernet. The default setting is 9600,
which is to support Jumbo frames.

3.2 Link Aggregation
Users can set up multiple links among multiple switches. Link Aggregation, is a method that tie some physical
ports together as one logical port, to enlarge bandwidth. This switch supports up to 13 groups of Link
Aggregation, with 2 to 8 port as one group.
Note: If any port in the link aggregation group is disconnected, data packet sent to the disconnected port will
share load with another connected port in this aggregation group.
3.2.1 Static Aggregation
Users can configure static aggregation of switch’s ports. After Clicking the menu “Port Configure" >
"Aggregation" > "Static", the following window will appear for making static aggregation settings.

Note: The switch allows a maximum of 8 ports to be aggregated as 1 static trunk group at the same time.
3.2.2 LACP Aggregation
Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between
Partner Systems that require high-speed redundant links. 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. For more detailed information, refer to the IEEE 802.3ad
standard.
Users can create dynamic aggregation group for switches. After Clicking "Port Configure" > "Aggregation" >
"LACP", users can set the LACP configuration in following screen.

Key
The Key value incurred by the port, range 1-65535. The Auto setting will set the key
as appropriate by the physical link speed, 10Mb = 1, 100Mb = 2, 1Gb = 3. Using the
Specific setting, a user-defined value can be entered. Ports with the same Key value
can participate in the same aggregation group, while ports with different keys cannot.
Role
The Role shows the LACP activity status. The Active will transmit LACP packets each
second, while Passive will wait for a LACP packet from a partner (speak if spoken to).
Timeout
The Timeout controls the period between BPDU transmissions. Fast will transmit
LACP packets each second, while Slow will wait for 30 seconds before sending a
LACP packet.
Prio
The Prio controls the priority of the port. If the LACP partner wants to form a larger
group than is supported by this device then this parameter will control which ports will
be active and which ports will be in a backup role. Lower number means greater
priority.
Click “Save”to store and activate settings.
3.3 Port Mirroring
Configure Port Mirroring on this page. This function provides monitoring of network traffic that forwards a copy
of each incoming or outgoing packet from one port of a network switch to another port where the packet can be
studied. It enables the manager to keep close track of switch performance and alter it if necessary.
To configure Mirror settings, please click "Port Configure" > "Mirroring". The following screen will appear as:

Click "Save" to store and activate settings.
Note: You cannot set fast speed port(s) mirror to a low speed port. For example, there is problem if you try to
mirror 100Mbps port(s) to a 10 Mbps port. So the destination port should have equal or higher speed
compared to source port. The source port and destination port should not be same one.

Description
Port mirror to
Frames from ports that have either source (rx) or destination (tx) mirroring enabled
are mirrored on this port. Disabled disables mirroring.
Mode
Select source port mirror mode.
Rx only Frames received on this port are mirrored on the mirror port. Frames
transmitted are not mirrored.
Tx only Frames transmitted on this port are mirrored on the mirror port. Frames
received are not mirrored.
Disabled Neither frames transmitted nor frames received are mirrored.
Enabled Frames received and frames transmitted are mirrored on the mirror port.
Note: For a given port, a frame is only transmitted once. It is therefore not possible
to mirror port Tx frames. Because of this, mode for the selected mirror port is
limited to Disabled or Rx only.
