Chapter 4 Network Application
This chapter provides sample applications to help the user to have a better idea of actual
switch function applications. A sample application of the switch is seen below:
17
4.1 X-Ring Application
The CWFE8MS/DIN switch supports the X-Ring protocol that can allow your network
system to recover from a network connection failure within 300ms or less, making your
network system more reliable. The X-Ring algorithm is similar to the spanning tree
protocol (STP) algorithm but it has a faster recovery time than STP. An X-Ring
application figure is shown below:
18
4.2 Coupling Ring Application
Within the network there maybe more than one X-Ring group. By using the coupling ring
function more than one X-Ring can be connect for redundant backup. This can ensure
the transmission between the two ring groups will not fail. A sample of the coupling ring
application figure is shown below:
19
4.3 Dual Homing Application
The Dual Homing function is designed to prevent a lost connection between the X-Ring
group and upper level/core switch. The Dual Homing function only works when the
X-Ring function is active. The maximum allowable Dual Homing port is set at one in a
X-Ring group.
[NOTE] In Dual Homing application architecture, the upper level switches need to enable
Rapid Spanning Tree protocol.
20
Chapter 5 Web-Based Management
This section introduces the configuration and functions of the Web-Based management.
The following configuration steps are based on the firmware version 1.06.
5.1 About Web-based Management
On the CPU board of the switch there is an embedded HTML web site residing in the
flash memory, which offers advanced management features and allows users to manage
the switch from anywhere on the network through a standard browser such as Microsoft
Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0. And, it is applied for Java
Applets for reducing network bandwidth consumption, enhance access speed and
present an easy viewing screen.
[NOTE] By default, IE5.0 or later version does not allow Java Applets to open sockets.
The user has to intentionally modify the browser settings to enable Java Applets to use
network ports.
21

29
5.9 VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain that
would allow you to isolate network traffic so only the members of the VLAN will receive
traffic from the same members of VLAN. Basically, creating a VLAN from a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2 switch.
However, all the network devices are still physically plugged into the same switch.
The switch supports port-based and 802.1Q (tagged-based) VLAN. In the default
configuration, VLAN operation mode default is Disable.
VLAN Configuration interface
30
5.9.1 Port-based VLAN
Packets can go among only members of the same VLAN group. All unselected ports are
treated as belonging to another single VLAN. If the port-based VLAN is enabled, the
VLAN-tagging is ignored.
In order for an end station to send packets to different VLANs, it has to be either capable
of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is
capable of classifying and tagging the packet with a different VLAN ID, based on not only
default PVID but also other information about the packet, such as the protocol.

5.9.2 802.1Q VLAN
Tagged-based VLAN is an IEEE 802.1Q specification standard. It is possible to create a
VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a
technique to insert a “Tag” into the Ethernet frames. The Tag contains a VLAN Identifier
(VID) that indicates the VLAN numbers.
All ports on the switch belong to a default VLAN. The VLAN ID is 1. The default VLAN
cannot be deleted. The maximum number of VLAN groups is 64.

2.
Modify RSTP state. After modifying, select
RSTP mode: enables RSTP function before configuring the related parameters
Priority (0-61440): a value used to identify the root bridge. The bridge with the
lowest value has the highest priority and is selected as the root. If the values
change, user has to reboot the switch. The value must be a multiple of 4096
according to the protocol standard rule.
Max Age (6-40): the number of seconds a bridge waits without receiving
Spanning-tree
Protocol
configuration
messages
before
attempting
a
reconfiguration. Enter a value between 6 through 40.
Hello Time (1-10): the time that controls the switch and sends out the BPDU
packet to check RSTP current status. Enter a value between 1 through 10.
Forward Delay Time (4-30): the number of seconds that a port waits before
changing from its Rapid Spanning-Tree Protocol learning and listening states to
the forwarding state. Enter a value between 4 through 30.
46
[NOTE]
1.
Must follow the rule to configure the MAX Age, Hello Time, and Forward
Delay Time.

1. Select the port in Port column
2. Path Cost: The cost of the path to the other bridge from this transmitting bridge at the
specified port. Enter a number 1 through 200000000.
3. Priority: Decide which port should be blocked by priority in the LAN. Enter a number
0 through 240. The value of priority must be the multiple of 16.
4. Admin P2P: Some of the rapid state transactions that are possible within RSTP are
dependent upon whether the port concerned can only be connected to exactly one
other bridge (i.e. it is served by a point-to-point LAN segment), or can be connected
to two or more bridges (i.e. it is served by a shared-medium LAN segment). This
function allows the P2P status of the link to be manipulated administratively. True is
P2P enabled. False is P2P disabled.
5. Admin Edge: The port directly connected to end stations cannot create a bridging
loop in the network. To configure the port as an edge port, set the port to “True”
status.
6. Admin Non STP: The port includes the STP mathematic calculation. True does not
include STP mathematic calculation. False does include the STP mathematic
calculation.

5.15 X-Ring
X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is
similar with STP or RSTP, but the algorithms are not the same.
In the X-Ring topology, every switch should enable the X-Ring function and assign two
member ports in the ring. Only one switch in the X-Ring group would be set as a backup
switch that one of two member ports would be blocking, called the backup port, and
another port is called the working port. Other switches are called working switches and
their two member ports are called working ports. When the network connection fails, the
49
backup port will automatically become a working port to recover from the failure.
The switch supports one Dipswitch for configuring the switch as the ring master or slave
mode. The ring master has the rights to negotiate and place the command to other
switches in the X-Ring group.
If there are 2 or more switches are in master mode, then
software will select the switch with lowest MAC address number as the ring master. The
X-Ring master ring mode will be enabled by the DIP Switch. When the switch is set to the
master ring mode, the X-Ring configuration interface will display the switch as the master
ring with a message. Also, you can identify the switch as the ring master from the R.M.
LED panel on the LED panel on the switch.
The system also supports the coupling ring that can connect 2 or more X-Ring groups for
the redundant backup function and dual homing function that prevents a connection loss
between the X-Ring group and the upper level/core switch.
Enable X-Ring: To enable the X-Ring function. Select the check box to enable the
X-Ring function.
1st & 2nd Working Ports: Assign two ports as the member ports. One port will be
working port and one port will be the backup port. The system will automatically
decide which port is the working port and which port is the backup port.
Enable Coupling Ring: To enable the coupling ring function. Select the check box
to enable the coupling ring function.
Coupling port: assign the member port
Control port: set the switch as the master switch in the coupling ring.
Enable Dual Homing: set up one of the ports on the switch to be the Dual Homing
port. In an X-Ring group, the maximum Dual Homing port is one in each X-Ring
group. Dual Homing only works when the X-Ring function enabled.
Select
to apply the configuration
50
X-Ring Interface
[NOTE]
1. When the X-Ring function is enabled, RSTP has to be disabled. The X-Ring function
and RSTP function cannot be active at the same time.
2. Remember to use “Save Configuration”, otherwise the new configuration will be lost
when the switch is powered off.
5.16 QoS Configuration
Configure Qos setting of the every port.
QoS Policy: Select the QoS policy rule
Using the 8,4,2,1 weight fair queue scheme: the switch will follow 8:4:2:1
rate to process priority queue from highest to lowest queue. For example: the
system will process 8 high queue packets, 4 middle queue packets, 2 low
queue packets, and the one lowest queue packets at the same time.
Use the strict priority scheme: the higher queue will always be process first,
except higher queue is empty.
Priority Type: each port has 5 priority type selections
51
Port-base: the port priority will follow the default port priority that the user has
assigned – High, middle, low, or lowest
COS only: the port priority will only follow the COS priority that the user has
assigned
TOS only: the port priority will only follow the TOS priority that the user has
assigned
COS first: the port priority will follow the COS priority first, and then other
priority rule
TOS first: the port priority will follow the TOS priority first, and the other priority
rule
COS priority: Set the COS priority level 0~7
TOS priority: the system provides 0~63 TOS priority level. Each level has 4 types of
priority – high, mid, low, and lowest. The default value is “lowest” priority for each
level. When the IP packet is received, the system will check the TOS level value in
the IP packet that has been received. For example: user set the TOS level 25 is high.
The port 1 is following the TOS priority policy. When the packet received by port 1,
the system will check the TOS value of the received IP packet. If the TOS value of
received IP packet is 25(priority = high), and then the packet priority will have highest
priority.
[NOTE] QoS and rate control cannot exist at the same time.

5.17 IGMP
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. IGMP has three fundamental
types of message as follows:
Message
Description
A message sent from the querier (IGMP router or
Query
switch) asking for a response from each host
belonging to the multicast group.
A message sent by a host to the querier to indicate
Report
that the host wants to be or is a member of a given
group indicated in the report message.
A message sent by a host to the querier to indicate
Leave Group
that the host has quit to be a member of a specific
multicast group.
The User can enable IGMP protocol and IGMP Query function here. The IGMP
snooping information that identifies VLAN ID, member port, and IP multicast address
range from 224.0.0.0 through 239.255.255.255 will be displayed as below:

Select the proper use unshielded twisted-pair UTP cable to construct your network.
Please check that you are using the correct cable. Use unshielded twisted-pair (UTP)
or shield twisted-pair (STP ) cable for RJ-45 connections: 100 Category 3, 4 or 5
cable for 10Mbps connections or 100 Category 5 cable for 100Mbps connections.
Also be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
Diagnosing LED Indicators: the CWFE8MS-DIN can be easily monitored through
panel indicators to assist in identifying problems, that describes common problems a
user might encounter and where a user can find possible solutions.
If the power indicator does turn on when the power cord is plugged in, there might
be a problem with the power cord. Check for loose power connections, power losses
or surges at the power outlet. If you still cannot resolve the problem, contact the
ComNet for assistance.
If the CWFE8MS-DIN LED indicators are normal and the connected cables are
correct but the packets still cannot be transmitted, please check the system’s
Ethernet devices’ configuration or operational status.
