Overview
Introduction
To create reliability in your network, the ComNet CNGE8FX4TX4MS 4 10/100/1000T + 4 SFP
Managed Switch comes equipped with a proprietary redundant network protocol—X-Ring
provides users with an easy way to establish a redundant Ethernet network with ultra
high-speed recovery time less than 20ms. Also, the long MTBF (Mean Time Between Failures)
ensures that the switch will continue to operate until a Gigabit network infrastructure has
been established, without requiring any extra upgrade costs.
Aside from 4 x 10/100/1000Base-T fast Ethernet ports, the CNGE8FX4TX4MS comes
equipped with 4 SFP (mini-GBIC) ports. Traditional RJ45 ports can be used for uplinking
wide-band paths in short distance (< 100 m), while the SFP slots can be used for the
application of wideband uploading and long distance transmissions to fit the field request
flexibility. Also, the long MTBF (Mean Time Between Failures) ensures that the
CNGE8FX4TX4MS will continue to operate until a Gigabit network infrastructure has been
established, without requiring any extra upgrade costs.
SFP Advantages
The SFP fiber slots provide a lot of flexibility when planning and implementing a network. The
slot can accept any SFP-type fiber module and these modules are designed for transmitting
over distances of either 550m (multi-mode), 10km, 30km, 50km, 70km or 110km
(single-mode)—and the slot supports SFP modules for WDM single-fiber transmissions. This
means that you can easily change the transmission mode and distance of the switch by
simply pulling out the SFP module and plugging in a different module. The SFP modules are
hot-swappable and plug-and-play.
SFP with DMI (Digital Monitoring Interface) function
The ComNet™ SFP supports a digital monitoring interface (DMI) function that allows
real-time access to device operating parameters, and includes optional digital features such
Page 8
2
as soft control and monitoring of SFP I/O signals. In addition, you can set up the action of
alarms and warnings by ports to manage your devices.
High-Speed Transmission
The CNGE8FX4TX4MS includes a switch controller that can automatically sense transmission
speeds (10/100/1000 Mbps). The RJ45 interface can also be auto-detected, so MDI or MDI-X
is automatically selected and a crossover cable is not required. All Ethernet ports have
memory buffers that support the store-and-forward mechanism. This assures that data is
properly transmitted.
Dual Power Input
The redundant power input design of the CNGE8FX4TX4MS is with power reserve protection
to prevent the switch from being damaged by using the wrong power source. When one of
power input has failed, the P-Fail LED will turn on and send an alarm through a relay output to
notify the user.
Flexible Mounting
The CNGE8FX4TX4MS is a compact size and can be mounted on a DIN-rail or panel. It can
be used in any location where space is scarce.
Advanced Protection
The power line of the CNGE8FX4TX4MS supports up to 3,000 VDC EFT protection, which
protects the switch from unregulated voltage and provides greater reliability. This high
voltage protection feature protects all the ports and makes the CNGE8FX4TX4MS suitable for
us in harsh industrial environments
Wide Operating Temperature
The ambient operating temperature of the CNGE8FX4TX4MS is between -40oC ~ 75oC.
Page 9

Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100/1000 Base-TX port has 2
LEDs that display the link status and transmission speed. The three power indicators: PWR1,
PWR2 and P-Fail assist in diagnosing any problems quickly.

Page 27
21
X-Ring Application
The switch supports the X-Ring protocol that can help the network recover from network
connection failure within 20ms or less, and make the network system more reliable. The
X-Ring algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm
but its recovery time is less than STP/RSTP. The figure below is a sample of X-Ring
application.
Page 28
22
Coupling Ring Application
In the network, it may be necessary to have more than one X-Ring group. By using the
coupling function it is possible to connect each X-Ring for a redundant backup. This will
ensure the transmission between two ring groups will not fail. The following figure is an
example of the coupling ring feature.
Page 29
23
Note
In Dual Homing application architecture, the upper level switches must
enable Rapid Spanning Tree protocol.
Dual Homing Application
The Dual Homing function is designed to prevent a connection loss between the X-Ring
group and an upper level/core switch. By assigning two ports on the switches as Dual
Homing ports, they will become the designated backup ports in the X-Ring group. The Dual
Homing function only works when the X-Ring function is made active. Each X-Ring group can
only have one Dual Homing port.
Page 30

Console Management
Connecting to the Console Port
The cable supplied with the switch has an RS232 connector on one end and the other end is
an RJ45 connector. Attach the end of the RS232 connector to a PC or terminal and the other
end of RJ45 connector to the console port of switch. The connected terminal or PC must
support the terminal emulation program.

Web-Based Management
About Web-based Management
On CPU board of the switch there is an embedded HTML web site residing in the flash
memory. This Graphic User Interface (GUI) 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 6.0 or later version. It is applied for
Java Applets to reducing the network bandwidth requirement while enhancing access speed
and presenting an easy viewing screen.
Preparing for Web Management
Before using the web-based management interface, install the switch on the network and
make sure that any one of the PCs on the network can connect with the switch through the
web browser. The switch’s default IP address, subnet mask, username and password is
shown below:
IP Address: 192.168.10.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.10.254
User Name: admin
Password: admin

IP Configuration
To configure the IP Settings and DHCP client function
DHCP Client: When DHCP client function is enabled, the switch will be assigned an IP
address from the network DHCP server. The default IP address will be replaced by the
DHCP server assigned IP address. After the user selects Apply button, a popup dialog
box appears. This is to inform the user that when the DHCP client is enabled, the current
IP will be lost and the user should find the new IP address on the DHCP server.
IP Address: Assigning the IP address that the network is using. If the DHCP client
function is enabled, and the user does not need to assign an IP address, the network
DHCP server will assign the IP address for the switch and display it in this column. The
default IP address is 192.168.10.1.

Port Trunk
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. It can also move the link to that Link Aggregation Group and enable its transmission
and receive functions to occur in an orderly manner. Link aggregation lets you group up to
four consecutive ports into two dedicated connections. This feature can expand bandwidth to
a device on the network. LACP operation requires full-duplex mode, more detailed
information refers to IEEE 802.3ad.
Aggregator setting
1. 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.
2.
Group ID: There are three trunk groups to provide configure. Choose the Group ID and
select .
3. LACP: If enabled, the group is LACP static trunk group. If disabled, the group is the local
static trunk group. All ports support LACP dynamic trunk group. If connected to the
device that also supports LACP, the LACP dynamic trunk group will be created
automatically.
4. Work ports: allows a maximum of four ports to be aggregated at the same time. With
LACP static trunk group, the exceed ports are on standby and can be aggregated if the
working ports fail. If it is part of the local static trunk group, the number of ports must be
the same as the group member ports.
5.
Select the ports to join the trunk group. Allow max four ports can be aggregated at the
same time. Select button to add the port. To remove unwanted ports, select
the port and select button.
6. If LACP enabled, you can configure LACP Active/Passive status in each of the ports on
State Activity page.

Aggregator Information
When you set the aggregator setting with LACP disabled, the local static trunk group
information will be displayedhere.
Port Trunk – Aggregator Information interface
Page 80
74
Note
1. A link having either two active LACP ports or one active port can
perform dynamic LACP trunk.
2. A link has two passive LACP ports will not perform dynamic LACP
trunk because both ports are waiting for an LACP protocol packet
from the opposite device.
3. If you are the active LACP’s aggregator, after you have selected trunk
port, the active status will be created automatically.
State Activity
When you setup the LACP aggregator, you can configure port state activity. You can select or
deselect the port. When you mark the port and select button the port state activity
will change to Active. Opposite is Passive.
Active: The port automatically sends LACP protocol packets.
Passive: The port does not automatically send LACP protocol packets, and responds
only if it receives LACP protocol packets from the opposite device.

Port Mirroring
The Port mirroring is a method for monitoring traffic in switched networks. Traffic through the
ports can be monitored by one specific port. That means traffic that goes in or out monitored
(source) ports will be duplicated into a mirror (destination) port.
Destination Port: There is only one port can be selected to be the destination (mirror)
port for monitoring both RX and TX traffic that comes from the source port. Or, use one
of two ports for monitoring RX traffic only and the other port for TX traffic only. The user
can connect the mirror port to LAN analyzer or Netxray.
Source Port: The ports that the user wants to monitor. All monitored port traffic will be
copied to a mirror (destination) port. The user can select multiple source ports by
checking the RX or TX check boxes of the ports to be monitored.
And then, select button.
Port Trunk – Port Mirroring interface

Rate Limiting
You can set up every port’s bandwidth rate and frame limitation type.
Ingress Limit Frame type: select the frame type that wants to filter. The frame types
have four options for selecting: 1) All, 2) Broadcast/Multicast/Flooded Unicast, 3)
Broadcast/Multicast and 4) Broadcast only.
Broadcast/Multicast/Flooded Unicast, Broadcast/Multicast and Bbroadcast only types
are only for ingress frames. The egress rate only supports All type.
Rate Limiting interface
All the ports support port ingress and egress rate control. For example, assume port 1 is
10Mbps, users can set its effective egress rate at 1Mbps, ingress rate at 500Kbps. The
switch performs the ingress rate by packet counter to meet the specified rate.
Ingress: Enter the port effective ingress rate(The default value is ‘0’)
Egress: Enter the port effective egress rate(The default value is ‘0’)
And then, select to apply the settings
Page 83

DMI (Digital Monitoring Interface)
You can see the transceiver’s status by ports and set up an action when detecting the
exceptional value. The action includes the following options.
Off: The port will be shut down when detecting the exceptional value.
e-mail: The port will send an e-mail to the administrator when detecting the
exceptional value.
DMI interface
Ports 5 to 8 support the DMI function. The DMI table (above) shows five parameters and
four warning and alarm indicators. All of these warning and alarm indications are defined
and supported by SFP transceivers with the DMI function.
And then, select to apply the settings

VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, that
would allow you to isolate network traffic. Only the members of the VLAN will receive traffic
from the same members of VLAN. Basically, creating a VLAN from a switch is the logical
equivalent of reconnecting a group of network devices to another Layer 2 switch. However,
all the network devices are still plugged into the same switch physically.
The switch supports port-based and 802.1Q (tagged-based) VLAN. The default configuration
of VLAN operation mode is Disable.
VLAN Configuration interface
Page 85
79
VLAN configuration - Port-based VLAN
Packets can go among only members of the same VLAN group. Note 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 VLAN groups, 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 different VLAN ID based on not only
default PVID but also other information about the packet, such as the protocol.

802.1Q VLAN
A tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to
create a VLAN across devices from different switch venders. An 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.
You can create tag-based VLAN, and enable or disable the GVRP protocol. There are 256
VLAN groups to provide a configuration for. Enable 802.1Q VLAN, and all ports on the switch
belong to a default VLAN, VID is 1. The default VLAN cannot be deleted.
GVRP allows automatic VLAN configuration between the switch and all nodes. If the switch is
connected to a device with GVRP enabled, you can send a GVRP request using the VID of a
VLAN defined on the switch; the switch will automatically add that device to the existing
VLAN.

Rapid Spanning Tree
Note
Follow the rule to configure the MAX Age, Hello Time, and Forward Delay Time.
2 x (Forward Delay Time value -1) >= Max Age value >= 2 x (Hello Time value +1)
Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol and
provides for faster spanning tree convergence after a topology change. The system also
supports STP and the system will auto detect the connected device that is running STP or
RSTP protocol.
RSTP - System Configuration
User can view spanning tree information about the Root Bridge
User can modify RSTP state. After modification, select button
RSTP mode: user must enable or disable 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 value
changes, the user must reboot the switch. The value must be multiple of 4096
according to the protocol standard rule
Max Age (6-40): the number of seconds a bridge waits without receiving a
Spanning-Tree Protocol configuration message before attempting a reconfiguration.
Enter a value between 6 through 40
Hello Time (1-10): the time that the switch controls 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 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

RSTP - Port Configuration
You can configure path cost and priority of every port.
1. Select the port in Port column.
1. 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.
2. Priority: Decide which port should be blocked by priority in LAN. Enter a number 0
through 240. The value of priority must be the multiple of 16.
3. 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
Page 92

status of the link to be manipulated administratively. True is P2P enabling. False is P2P
disabling.
4. Edge: The port directly connected to the end stations cannot create a bridging loop in
the network. To configure the port as an edge port, set the port to True status.
5. Non STP: The port includes the STP mathematic calculation. True is not including STP
mathematic calculation. False is including the STP mathematic calculation.

SNMP Configuration
Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes
(servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables
network administrators to manage network performance, find and solve network problems,
and plan for network growth. Network management systems learn of problems by receiving
traps or change notices from network devices implementing SNMP.

QoS Configuration
You can configure QoS policy and priority setting, per port priority setting, COS and TOS
setting.
QoS Policy and Priority Type
QoS Policy: select the QoS policy rule.
Use an 8,4,2,1 weighted fair queuing scheme: The switch will follow 8:4:2:1 rate
to process priority queue from highest to lowest queue. For example, when the
system processes, 1 frame of the lowest queue, 2 frames of the low queue, 4 frames
of the middle queue, and 8 frames of the high queue will be processed at the same
time in accordance with the 8,4,2,1 policy rule.
Use the strict priority scheme: The higher queue will always be processed first,
except when the higher queue is empty.
Priority Type: there are five priority type selections available. Disable means no priority
type is selected.
Port-base: the port priority will follow the Port-base that you have assigned – high,
middle, low, or lowest.
COS only: the port priority will only follow the COS priority that you have assigned.
TOS only: the port priority will only follow the TOS priority that you have 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.

Port: each port has 4 priority levels – high, middle, low, and lowest.
Select .
COS Configuration
Set up the COS priority level.
COS priority: Set up the COS priority level 0~7 –high, middle, low, lowest.
Select .
TOS Configuration
Set up the TOS priority.
TOS priority: the system provides 0~63 TOS priority level. Each level has four types of
priority – high, middle, 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 only. When the port 1 packet received, 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.
