1.1 Introduction

The Compex SXP2224WM is a 24-ports 10/100 Mbps + 1 modular slot web-managed
switch that offers fiber or copper-based gigabit connectivity through its expansion
modules. The SXP222WM comes with enhanced features that can be catered for
today’s most demanding Ethernet-based switching applications. It is the most ideal
workgroup switch for any small and medium enterprises.

1.2 Features and Benefits

Compex SXP2224WM is designed with the following features:

• 1 modular port for 1000Base-T or 1000Base-FX

Compex SXP2224WM is designed with an expansion slot which supports 2
types of optional modules: 2 Gigabit Copper Module and 1000T Gigabit Copper
+ 1 GBIC slot.

• Web-based Management Interface

configuration process with a user-friendly web-based interface. Simply connect
Compex SXP2224WM to a workstation and configure the switch for your
network via a Java-enabled web browser.

Through the management interface, you can also change the transmission mode
of all ports on Compex SXP2224WM switch. This means that you can change
the operating mode of any port to 10 Base-T half duplex, 10 Base-T full duplex,
100 Base-TX half duplex, 100 Base-TX full duplex or N-way Auto-negotiation
at any time.

• Port Trunking increases cascading bandwidth

Up to 7 groups may be defined for Port Trunking, delivering up to 800Mbps
cascading bandwidth between two switches.

Chapter 1 Product Overview

2

• Port Mirroring for monitoring purposes

This function allows you to set up a ‘mirror’ port on any specified port/s, such
that you can monitor the traffics of the monitored port/s without intervening
them. In effect, the traffics on the monitored port/s are replicated on the mirror
port, such that you can use a protocol analyzer to analyze the traffic for specific
problem.

• Port Priority for traffic prioritization (QoS)

Compex SXP224WM supports first come first serve basis. You can set the port
priority according to the types of operations you are working in.

• Bandwidth Control for limiting network bandwidth

Bandwidth control allows you to specify the maximum line bandwidth that a
particular transfer operation can use, so that it can be carried out at low priority
in the background without interfering any users or network applications. It is
ideally suitable for interactive network users.

• Virtual LAN (VLAN)

Compex SXP2224WM can support both port-based and 802.1Q VLANs. It
allows network administrator to separate the network into a few segments by
defining which port belong to which VLAN segment. This can effectively
control broadcast and multi-cast packet flooding the network. This not only
improves the network performance, but also provides security between
workgroups.

6.3 Trunk Configuration

Port Trunking is the ability to group together several switch ports to increase the
bandwidth between Compex SXP2224WM and other switch/es. This is an
inexpensive method to increase throughput between switches. We define the Port
Trunking as the ability to group a set of ports into a single logical link. The port trunk
acts as single link between switches. It does not create a loop even though it is
physically connected.

Compex SXP2224WM uses Port-based method for load balancing. Port-based method
is to assign each port outside the trunk to a trunk port. For example, port A is assigned
to trunk port B, then packets from port A destined to the trunk will be forwarded to
port B. Please note that the assignment is done by management software, so you do
not need to make the assignment manually.

NOTE

You are not allowed to configure the same port in different trunking groups on
a switch unit.

You can select up to 7 trunking
groups for a switch unit. A maximum
of 4 trunking port is allowed in a
trunk group.

Select on the radio button for your
setting and click on the “Apply”
button to update the changes.

Kindly refer to the example on the
next section.

6.3.1 Examples on Port Trunking

From Figure 6.3b, two Compex SXP2224WM units are used to perform the
trunking ability. For unit 1, port 1 and 5 are selected as trunking ports; and
port 26 is connected to a control station. For unit 2, port 5 and 6 are selected
as trunking ports. After selecting the respective trunking group for
individual switches, all SXP2224WM units combined the bandwidth to
increase the network speed.

6.4 Virtual LAN Configuration

Virtual LAN is actually equated to a broadcast domain. In a VLAN, all end-stations
communicate with each other as in a local LAN although they may be not on the same
physical segment. However, all data packets in a VLAN are constrained, so different
end stations in different VLANs cannot communicate with each other directly.
Compex SXP2224WM not only supports port-based VLAN, i.e. the VLAN is
specified by selecting a group of ports VLAN, but also tagged VLAN.

In a tagged VLAN application, you still can assign specific ports within a switch to be
a VLAN group. In addition, the data transferred within the VLAN group is tagged
with an ID as specified with the 802.1Q Tagged VLAN standard. It allows the VLAN
information to be carried along as the data flow from switch to switch. It also allows a
port to carry multiple VLANs data stream. It is more flexible and scalable than the
untagged VLAN application. However, all networking devices have to support the

802.1Q Tagged VLAN standard for VLAN Tagging system to work.

Figure 6.4a VLAN Configuration

6.4.1 Example on PortBased VLAN

In an untagged VLAN application, you can assign a group of ports within a
switch as members of a specific VLAN. Data traffic would be confined
within the member ports. In this way, devices connected with the switch can
be partitioned into distinct groups each corresponds to a different VLAN.
The partition (VLAN) can be expanded when two untagged VLANs are
connected together through their member ports. No two VLANs can be
overlapped. Each VLAN is separate from the rest. It provides a simple
means to implement a secure and managed network.

VLAN Mode:

• Disable

• PortBased

• 802.1Q

Figure 6.4b illustrated the setup of port based VLAN in a company. Port 2
and 6 of Compex SXP2224WM are attached to two Ethernet switches ; Port
16 and 24 are attached an Ethernet switch individually. When Port 2 and 6
are assigned as port based VLAN, the PCs in VLAN 1 will be able to
communicate with one another within the same VLAN. However, they are
not allowed to communicate with other departments.

6.5 Port Monitoring Configuration

This function allows you to set up a ‘mirror’ port of any specified port/s from 1 to 26,
such that you can monitor the transmitted or received traffics of the monitored port/s
without intervening them. You can then use a protocol analyzer to analyze the traffic
for that port for any specific problem.

Figure 6.5a Port Monitoring

6.5.1 Examples on Port Monitoring

The example shown in Figure 6.5b illustrated that port 26 which is
connected to a control station, is assigned to be a monitoring port; and port
24 is configured as a monitored port. This means that when a packet is
being sent/received to/from PC 24, the control station will also get a
duplicate copies.

6.6 QoS Configuration

Quality of Service (QoS) refers to the capability of a network to provide a better
service to select network traffic over various technologies, such as Frame Relay,
Asynchronous Transfer Mode (ATM), etc. The primary goal of QoS is to provide
priority including dedicated bandwidth, controlled jitter and latency.

With this ability, Compex SXP2224WM is able to improve the loss characteristics
and ensure that the priority for one or more flows does not make other flow fails.

Disable QoS Priority

High:Low = 5:1

No QoS priority function is activated

The system will process 5 high priority
packet, and then 1 low priority packet

High:Empty Then Low High:Low = 7:1

The system will process all high priority packet
first, and then proceed to low priority packet

The system will process 7 high priority
packet, and then 1 low priority packet

High:Low = 3:1

The system will process 3 high priority packet,
and then 1 low priority packet

QoS Mode section

This mode will affect the levels (high or low) of all priority configuration.

Static Port Ingress Priority section

By default, the setting in the Static Port Ingress Priority is “Off”. At this stage, the
switch will appoint the packets to low priorities.

If a normal packet is transmitted from a “high” or “low” setting port, Compex
SXP2224WM will deliver all the packets to its designated port according to the QoS
mode ratio setting.

802.1p* Priority section

If a tagged packet is being transmitted from any port, it will directs the packet to the
global setting. A tagged packet consists up to 8 traffic classes, ranging from 0 to 7.
The traffic classes can be set using switches, routers, servers or desktop systems.
Based on the tagged traffic classes, Compex SXP2224WM will then check the
priority values from the global setting, distribute the packets according the QoS mode
ratio setting to their designated ports respectively.

By default, the setting for 802.1p Priority is 4 high priority (7 to 4) and 4 low priority
(3 to 0). Please refer to Figure 6.6a.

Kindly note that the configuration in the Static Port Ingress Priority section does not
affect the global setting, and vice versa. This means that the global setting will still
remains as it is.

*802.1p is an IEEE standard for providing quality of service (QoS) in Ethernet
networks. It uses tagged packets and allows switches to transmit packets based on the
tagged priority value.

6.7 Bandwidth Control

In a network environment, massive data are being
transferred from one node to another node/s. And this
often caused serious slowdown problems for interactive
network users. This means that users are forced to
restructure their operations due to network load
limitations.

To overcome this problem, Compex SXP2224WM is
specially designed to control the bandwidth using
relatively bandwidth technique. It enables you to specify
the maximum line bandwidth (in Mbps) that a particular
transfer operation can use, so that it can be carried out in
the background, at a low priority without interfering other
users or other network applications.

Ensure that the Flow Control status is “On” before
configuring the bandwidth control. Please refer to Section

6.2 “Port Configuration” for details in activating Flow
Control function.

• Enter the bandwidth in
Mbps, where 0 indicates
“disable”

Broadcast Storm Filter

A broadcast storm occurs when a switch port receives a large number of broadcast
packets, and forwarding these packets causes the network to slow down or time out.
In order to prevent this, broadcast storm filter function is implemented to solve
performance degradation.
