DHCP Config
The Dynamic Host Configuration Protocol (DHCP) provides configuration
Parameters to Internet hosts. DHCP consists of two components: a protocol for delivering host-specific configuration parameters from a DHCP server to a host and a mechanism for allocation of network addresses to hosts. DHCP is built on a clientserver model, where designated DHCP server hosts allocate network addresses and deliver configuration parameters to dynamically configured hosts.
If you have set the TCP/IP protocol of your PC to dynamic IP address, the built-in
DHCP server will automatically assign the IP address/es within the range of DHCP
Start IP Address and DHCP End IP Address to the PCs connected in the same network. For dynamic WAN IP, the DNS IP address is obtained automatically from the ISP.
NOTE
If you are running different DHCP servers on your network, you will have to enable only one DHCP server to prevent any conflict in the network addressing.
IP Address
This IP (Internet Protocol) address uniquely identifies the Gateway in the network. This is the IP address that the users should point their Internet gateway to if fixed IP addresses are configured on the computers in the
Subnet Mask
This is the Subnet Mask to identify the class of the Gateway’s IP address. By default, Class C Subnet Mask
255.255.255.0 is set. The users may configure the network with Class A
(255.0.0.0) and Class B (255.255.0.0) network. However, the DHCP Server will assign this information if the computers are configured to dynamically obtain IP addresses.

DNS IP Address
DNS is an Internet service that translates domain names into IP addresses. If your
WAN connection is using Static IP, you should configure the primary and secondary DNS IP addresses with the
DNS information provided by your
Broadband Internet Service Provider. For other WAN connection types, the DNS IP addresses is obtained automatically from
ISP. The “Always use these DNS servers:” checkbox can be used to disable the automatic process, and your preferred
DNS IP addresses can be used.
DHCP Server
DHCP server dynamically assigns IP addresses to the PCs connected in the same network. DHCP comes with a built-in DHCP server that automatically assigns IP addresses, DNS and Gateway information to the computers connected in the same network. It has been pre-configured with IP address and Subnet Mask of
192.168.100.128 and 255.255.255.0 respectively.

5.6 NAT Config
Network Address Translation allows an IP-based network to manage its public
(Internet) addresses separately from its private (intranet) addresses. With NAT, each private IP address can be translated to a different public address, or multiple private addresses can be aliases to a single public one. To accomplish this, NAT software snoops both incoming and outgoing packets on the network. It modifies the source or destination address in the IP header to reflect the mapping between internal and external addressing for that network.
NAT functionality appears on Compex SGX3226 with low-level access to packets at the network boundary. Several variations on NAT have also been implemented to provide additional support for application-level protocols.

Chapter 5 Web-based Interface Configuration for Compex SGX3226
5.6.1 Static IP Setting (IP Forwarding)
To set a static IP Address,
1. Enter a private IP Address, such as 192.168.100.20, in the field provided and click Save button.
NOTE
You must enable the NAT function in the Configuration window if you are using a single IP address account (fixed static IP) and want to share this connection on your LAN.
5.6.2 Static Port Setting (Port Forwarding)
Defining Port-Forwarding Virtual Server
Port Forwarding redirects any incoming Internet request on the Public IP, based on its TCP/UDP Port number to another computer in the Private IP.
Hence, when a user from WAN sends a request to your network, Compex
SGX3226 (based on the Port–Forwarding configurations) will forward these requests to the assigned PC.
29
Chapter 5 Web-based Interface Configuration for Compex SGX3226
When to use Port–Forwarding Virtual Server
When your ISP assign you with only one fixed Public IP address, and you want to define the various servers (such as, FTP, HTTP, Netmeeting, Mail server etc) to specific Private IP address in your LAN; hence, you can choose to host the servers by using the Port-Forwarding Virtual server.
Example, suppose that you have a FTP Server with an IP address of
192.168.168.41. And your broadband ISP has assigned a Public IP address of 203.120.12.100 to the gateway. To support a Web Server in your Private
Network, you need to define an NAT Static Port-based Entry to forward
TCP port 21 (used by FTP) to 192.168.168.41. Every http://203.120.12.100 requests will then be forwarded to the FTP Server.
Follow the steps shown below to configure Static Port.
1. Go to NAT function at the Command Window. Select the type of
Server you wish to configure as shown in the figure below:
2. Key in the Private IP Address.
3. Next, choose a transport protocol, either TCP or UDP, for the respective IP Address.

5.6.3 Filtering Setting
Compex SGX3226 allows Packet Filtering rules be defined based on three factors, Source IP Address, TCP Port and Time. IP Packet Filtering examines the outgoing packets and decides whether to bypass or to block them. After the Packet Filtering rules have been defined, the users may select to bypass or to block the outgoing packets that do not match the rules.
For example, assume that a rule has been defined as "TCP Port 23 (used by
TELNET) from any IP on any day at any time". If the “forwarded” radio button is selected, all outgoing packets will be sent except TELNET session.
If the blocked radio button is selected, all outgoing packets will be blocked except TELNET session.
Click on Filtering section at the Configuration window and the GUI will appear as shown:

Chapter 7 Advanced Configuration for Compex SGX3226
Chapter 7 Advanced Configuration for Compex SGX3226
In this chapter, you can understand how the configuration on Spanning Tree Protocol (STP) was easily done. Compex SGX3226 implements Internet Group Multicast Protocol (IGMP) function which forwards multicast traffic intelligently. In fact, Simple Network Management Protocol
(SNMP) is also introduced to provide a standard mechanism to monitor and control network devices.
7.1 STP Config
Spanning Tree Protocol is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations.
Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur, some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.
7.1.1 STP Port
When Compex SGX3226 first powers up, all bridges will declare themselves to be the root. The one with the lowest priority will be the root.
The bridges will stop advertising themselves and use the BPDUs of the root bridge.
During normal operation for Compex SGX3226, the ports are either forwarding or disabling.
In a forwarding state, the network can send and receive frames which takes about 50 seconds for a port to go from disabling to forwarding.
In a blocking state, the port is not forwarding frames, but will receive the
BPDUs.
Active ports which can forward frames on the root bridge are known as designated ports.
41
Chapter 7 Advanced Configuration for Compex SGX3226
1. Select STP Config from the Command window.
Bridge Port
This option shows the port of the bridge that connects to the root bridge.
Priority
The lower the number has higher priority.
Path Cost
This option sets the Spanning Tree path cost for this port. A lower path cost represents higher transmission speed.
2. Select one port from 1 to 26 to connect to the root bridge.
3. Key in the value for Path Cost (from 1-65535) and set the priority
level (0-255).
42
Chapter 7 Advanced Configuration for Compex SGX3226
7.1.2 STP Bridge
Spanning-Tree Protocol defines a tree that spans all switches in an extended network. It forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.
Spanning-Tree Protocol operation is transparent to end stations, which are unaware whether they are connected to a single LAN segment or a switched
LAN of multiple segments.
This section shows how configuration is done in Spanning Tree parameters.
STP State
When STP is enabled, it will dynamically detect network looping owing to mis-configuration of the network topology. The redundant connectors will be disabled to avoid looping of packets. Looping would often result in flooding of broadcast packets, halting the normal traffic.
Root Priority
The priority of the switch is currently acting as the root. The bridge with the lowest value has the highest Spanning
Tree priority level and is related as the root.
43
Chapter 7 Advanced Configuration for Compex SGX3226
Hello Time
The Hello time of the Spanning Tree field shows the number of seconds between the transmissions of spanning
Tree protocol configuration messages.
Forward Delay
The Forward Delay field shows the number of seconds a port waits before changing from its Spanning Tree Protocol learning and listening states to the forwarding state. This wait is necessary so that other switches on the network ensure no loop is formed before they allow the port to forward packets.
Max Age
The maximum age time of the spanning tree shows the number of seconds the bridge waits without receiving Spanning Tree Protocol configuration messages before attempting a reconfiguration.
1. Select Spanning Tree state option and set Root Priority from 0 -
65535 s, and Hello Time from 1 - 10 s.
2. Key in the Forward Delay Time, Maximum Age and Hold Time.
3. Click Apply and Save button to update your configuration.

Advanced Configuration for Compex SGX3226
IGMP Config
Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for an Internet computer to report its multicast group membership to adjacent
routers. It allows Compex SGX3226 to forward multicast traffic intelligently. The switch "snoops" the IGMP query and report messages and forwards traffic to only the ports that request the multicast traffic. This prevents the switch from broadcasting the traffic to all ports and possibly affecting network performance.
The membership of a host group is dynamic - hosts may join and leave groups at any time. There is no restriction on the location or number of members in a host group. A host may be a member of more than one group at a time. A host need not be a member of a group to send datagrams to it.
Host Group Addresses
Host groups are identified by class D IP addresses, i.e., those with "1110" as their high-order four bits. Class E IP addresses, i.e., those with "1111" as their high-order four bits, are reserved for future addressing modes.
In Internet standard "dotted decimal" notation, host group addresses range from
224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is guaranteed not to be assigned to any group, and 224.0.0.1 is assigned to the permanent group of all IP hosts (including gateways). This is used to address all multicast hosts on the directly connected network. There is no multicast address (or any other IP address) for all hosts on the total Internet. The addresses of other well-known, permanent groups are to be published in "Assigned Numbers".

Chapter 7 Advanced Configuration for Compex SGX3226
1. Select IGMP Config from the Command window.
2. Choose enabled in the IGMP state field.
3. Click on the radio button to select the version for IGMP. Refer to the next section for the explanation on IGMP v1.0 and v2.0
4. Hit on the Apply button and save your setting.
7.2.1 Definition on IGMP v1.0 and v2.0
For IGMP v1.0,
The Internet Group Management Protocol (IGMP v1.0) is used by IP hosts to report their host group memberships to any immediately neighboring multicast routers. IGMP is an asymmetric protocol and is specified here from the point of view of a host, rather than a multicast router.
NOTE
NOTE: IGMPv1 has no leave mechanism. If a host no longer wants to receive the traffic, it simply quits. If it is the last, the router will not have any answers to its query and will delete the GDA for that subnet.
For IGMP v2.0,
IGMP v2.0 allows group membership termination to be quickly reported to the routing protocol, which is important for high-bandwidth multicast groups and/or subnets with highly volatile group membership.
Multicast routers use IGMP v2.0 to learn which groups have members on each of their attached physical networks. A multicast router keeps a list of multicast group memberships for each attached network, and a timer for each membership. "Multicast group memberships" means the presence of at least one member of a multicast group on a given attached network, not a list of all of the members.
When a host receives a General Query, it sets delay timers for each group
(excluding the all-systems group) of which it is a member on the interface from which it received the query.
46
Chapter 7 Advanced Configuration for Compex SGX3226
When a router receives a Report, it adds the group being reported to the list of multicast group memberships on the network on which it received the
Report and sets the timer for the membership to the [Group Membership
Interval].
When a host joins a multicast group, it should immediately transmit an unsolicited Version 2 Membership Report for that group, in case it is the first member of that group on the network
When a host leaves a multicast group, if it was the last host to reply to a
Query with a Membership Report for that group, it SHOULD send a Leave
Group message to the all-routers multicast group.
7.3 Stack Configuration
Stacking Management can be implemented in a multi-storey building or even in a geographically dispersed campus. Upon activating the stacking management functions, the system administrator is able to access to other switches easily.
By selecting the switch from the Stack Access field, you can configure any of the switches that are connected to the network.
NOTE
A stack can only accepts up to 16 switches, including the master switch. All switches in a particular stack must be in the same IP subnet.

Aging Control
Aging control is for the aging of address entries in the switch’s forwarding table. If the aging control is enabled, a learned address entry (not include the static entry) will be removed from the forwarding table if there is no update within a pre-determined period (1 ~ 128 seconds). It is useful because the resource of the forwarding table is limited. Enabling the aging control will not influence packets forwarding, for that the packet is forwarded to all other ports when the destination MAC address cannot be found in the forwarding table. If the aging control is disabled, all address entries will not be removed.
1. Go to Aging Control from the Command window.
2. Select “Enable” from the Aging Control option.
3. Enter the Maximum Age of the Address Entries. If the aging control is enabled, enter an integer from the range of 1 to 128 as the maximum age of address entries. If the aging control is disabled, this step can be skipped.

Chapter 10 Application on Virtual LAN
Chapter 10 Application on Virtual LAN
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.
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.
10.1 Untagged and Tag Configuration using Web-based Interface
71
Chapter 10 Application on Virtual LAN
VLAN C, VLAN D and VLAN E are assigned with VID of 02, 03 and 04 respectively. Switch 1 and Switch 2 are interconnected via Port 26, whereby the port are tagged with an ID. Control Station, PC 1, PC 2 and PC 3 are connected to Port 2,
9, 16 and 22 respectively. All Ethernet Ports are configured as untagged. All users are able to communicate with one another within the same VLAN. For example, the control unit is able to communicate with PC 1, but failed to communicate with PC 2 and PC 3. Creating VLAN E allows PC 2 to transmit data from switch 1 to switch 2 via tagged Port 26, without the need to connect another link in VLAN D.
Configuration for Switch 1
VLAN C
1. Open a browser and key in the IP address for Switch 1, such as 192.168.100.128.
2. Select VLAN Config from the command window and enabled the Status at
