2. Software Configuration
CS-2208G-8P supports web-based configuration. Upon the completion of hardware
installation, CS-2208G-8P can be configured through a PC/NB by using its web browser
such as Internet Explorer 6.0 or later.
Set the IP segment of the administrator's computer to be in the same range as CS-2208G-8P
for accessing the system. Do not duplicate the IP Address used here with IP Address of
CS-2208G-8P or any other device within the network. Please refer to the following steps
2.1 Example of Segment: (Windows 7)
Step 1 :
Please click on the computer icon in the bottom right window, and click “Open Network
and Sharing Center”
Step 2 :
In the Network and Sharing Center page, click on the left side of “Change adapter
setting” button

Step 3 :
In “Change adapter setting” Page, right click on Local LAN then select “Properties”

Step 4 :
In the “Properties” page, click the “Properties” button to open TCP/IP setting
Step 5 :
In Properties page for setting IP addresses, find “Internet Protocol Version 4
(TCP/IPv4)” and double click to open TCP/IPv4 Properties window
Double click

Step 6 :
Select “Use the following IP address”, and fix in IP Address to: 192.168.2.X
ex. The X is any number from 1 to 253
Subnet mask : 255.255.255.0
And Click "OK" to complete fixing the computer IP settings
Step 7 :
Open Web Browser
Without a valid certificate, users may encounter the following problem in IE7 when they try
to access system's WMI (http://192.168.2.200). There will be a “Certificate Error”, because
the browser treats system as an illegal website.
System login Overview page will appear after successful login.

2.2 System login
The CS-2208G-8P web switch default IP is 192.168.2.200
Into the management page as follows, please enter Username and password
Default IP Address: 192.168.2.200
Default Username and Password
Management Account
Root Account
User Name
root
Password
default
After Login page will display system information.

Menu Function
3. System

Model Name:Display switch model name.
Device Name: Administrator can modify the system name.
Firmware Version: Display system firmware version.
Build Date: Display firmware release date.
MAC Address: Display the system MAC Address.
IPv4 Address: Display system IP address of the current
Subnet Mask: Display network Mask
Gateway: Display Gateway IP Address.
Loop Status: Display network infrastructure whether there loop. (reference 11 Loop
function)
PoE Status: Display PoE used power.

4. Management
This page administrator can set system IP address and 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 IP Setup
Mode:
Static IP: Administrator can manual set IP Address of System
Dynamic IP: Administrator can select DHCP Client type.
Reset / Reboot System
Reset to default: Administrator can click the button to reset system default.
Reboot system: Administrator can click the button to reboot system.
Configuration System
Path: Display path for the restore config file.
Select file: Administrator can click button to find the restore config file in the PC.

Backup system Profile: Administrator can click the button to backup system profile.
Firmware Upgrade
Path: Display path for the firmware file.
Select firmware file: Administrator can click button to find the firmware file in the PC.
5.PoE
PSE Status:
The function can monitor PoE used power status / Module Temperature and PoE voltage
status.
Port Status / POE Global Setting
Administrators can control PoE usage through the per port On/Off option.
if port status color is green then expressed as POE start, If it's not then expressed as POE off

6.VLAN
The VLAN function administrator can set IEEE 802.1q Tag Based VLAN or Port Based VLAN.
System default is tag based VLAN.
PVID: Administrator can set Port tag VLAN ID
802.1Q VLAN: Administrator can set tag number for 802.1Q VLAN.
7.Link Aggregation
The 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.

Link Group Activity: Administrator can select active/passive of the Link Group
Activity.
Link Group Member: If LACP function is enabled, the Link Group member will
auto-display.
8. Port Mirror
Port mirroring function can mirror Ingress/Egress traffic, the packet can mirror to Destination
port and for analysis
Port Mirror Mode: Administrator can Select Ingress or Egress or Both for Mirror.
Select Monitor Port: Administrator can select monitor port.
Selected Monitor Port:Administrator can set selected ports to the mirror.
MAC DA: Destination Address
MAC SA: Source Address
Layer2 Packet Frame : The following example
Preamble SFD DA SA Ether type Payload ……..
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

9. 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.
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 select WFQ or Strict Priority type.

IEEE 802.1q QoS
Administrator can set Queue (weight) QoS by Tag VLAN.
Administrator can select WFQ or Strict Priority type.
Queue0 is Low Priority, Queue3 is High Priority.
Queue0 is Low Priority, Queue3 is High Priority.

10. Storm Control
Administrator can setup storm control of Broadcast / Multicast / Unicast.
11. Rate Limiting
The rate limiting function can be configured to limit the rate of traffic received on a particular
interface.
Administrator can select
Port: Display Port list.
Ingress/ Egress rate: Administrator can set ingress or Egress for rate limiting.
Administrator can select Unlimited or 512Kb ~ 512 Mb

12. 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.

13. 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 ".

14. Password
Administrator can change the Switch login password on this page. The default login
password is default
15. Logout
Clicking the logout button will log the administrator out of the management page.
