minal program may be a good choice. It can be accessed from the Start menu. Click START, then Programs, Accessories and then Hyper Terminal. MS-DOS based terminal program such as PC-PLUS, PROCOMM, can also make the connection with the device built-in software. The COM port should be configured as: ♦ ♦ ♦ ♦ ♦ Baud : 38400 Parity : None Data bits : 8 Stop bits : 1 Flow Control: none Once the terminal has connected to the device, power on the device. The terminal will display that it is loading the firmware.
To setup the IP address, please use “sys set ip” command in the following format: sys set ip For example, to configure the switch with the following IP settings: IP Address: 192.168.0.2 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.0.254 Press input the following command and press button: sys set ip 192.168.0.2 255.255.255.0 192.168.0.254 If the IP is successful configured, the switch will automatically restart as the following window.
3. WEB-BASED MANAGEMENT 3.1 Configuration As well as the menu-driven system configuration program, the agent module provides an embedded HTTP Web agent. This agent can be accessed by any computer on the network that using a standard Web browser (Internet Explorer 5.0 or above, or Netscape Navigator 4.5 or above). Using the Web browser management interface you can configure a switch and view statistics to monitor network activity.
3.2 Web Pages To access the Web-browser interface you must first enter the password. The default password is "admin" You will see the following screen comes out on the Web browser program: Figure 3-1: SGSW-4802 login Web Page After the password is entered you will see the main menu web screen of SGSW-4802. Figure 3-2: The start up screen of SGSW-4802 Web Page 3.3 Port Config This section allows you to have an easy access in configuring the ports of the management Switch.

dresses. It should be noted that if the cpu port (i.e. the switch port connected to the management workstation) is disabled, without doubt, the communication link between user and the switch will not proceed further. It is recommended to locate the link your PC used before disable the port state. Flow Control This feature enables or disables the Flow Control function of the port.
3.5 Trunk config The SGSW-4802 provides 2 trunk groups and maximum up to 4-ports per trunk. Port Trunking is the ability to group together several switch ports to increase the bandwidth between the management switch and other switch. This is an inexpensive method to increase throughput between switches (or to servers). 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.
3.6 Advanced Configuration The available options in “Advanced menu” are: STP Config The Spanning Tree Setup Screen IGMP Config The IGMP Setup Screen Stack Config The Stack Setup Screen SNMP Config The SNMP Setup Screen RMON Statistics Show RMON statistics information Port Security The Port Security Setup Screen MirrorPort Config The Mirror Port Setup Screen Aging Control The Aging Control Setup Screen Address Search The Address Search Setup Screen 3.
3.7.1 STP Port This function allows assigning Path Cost value and Priority level on each port of SGSW-4802. Please refer to the detail description of Path Cost and Priority and setup procedures shown as below. Description of Parameters Bridge Port This option shows the port of the bridge that connects to the root bridge. Path Cost The STA algorithm to determine the best path between devices uses this parameter.
3.7.2 STP Bridge This function provides to have a clearer view in Spanning Tree parameters of SGSW-4802. The STP Bridge screen in Figure 3-7 appears. Figure 3-7: The STP Bridge Web Page Description of 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.
Setup Procedures Step 1: Select Spanning Tree state option, either to enable or disable it. Step 2: Set Root Priority from 0 s – 65535 s, and Hello Time from 1 s – 10 s. Step 3: Key in the Forward Delay Time, Maximum Age and Hello Time. Step 4: Click “Apply” button and save it if everything is OK. ! NOTE The screen is divided into two sections.
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. ! 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. NOTE For IGMP v2.
Figure 3-9: The Stack Web Page After enable the stack function and the following screen in Figure 3-10 appears.

Step 6: After configure completed. Press “Save” to save the current configuration.
Figure 3-11: The Stack member list Web page ! NOTE ! NOTE ! NOTE Please note when choose “Master” from “Stacking State”. It allows user to assign this Switch as Master device in this stack group. Then the rest of the Switches should be slave device. Slave switch IP will be covered by Master one, and disappear temporarily. The slave IP address can be the same as Master IP address. Thus, if master switch is malfunction, you can still access the other switch by same IP address.
Figure 3-12: The Stack member list Web page 3.10 SNMP The management switch provides Simple Network Management Protocol (SNMP) over the UDP/IP transport protocol as defined in RFC 1517 for network management applications. The screen in Figure 3-13 appears. To control the access of the system, a list of community entries is defined. Each community entry consists of a community string and its access privilege. The Access privilege is either “Read Only” or “Read-Write”.
Figure 3-13: The SNMP Web Page 3.11 RMON Statistics This function allows use to view all port’s RMON Statistics. The RMON Statistics screen in Figure 3-14 appears.
3.12 Port Security Of all 50 ports, some of the end nodes may need to assign to the specific port. In order to fulfill this act, MAC Address should be added to that particular port. This is to ban other users from using the static port. A port can accommodate up to 20 MAC Addresses. The Port security screen in Figure 3-15 appears. Figure 3-15: Port Security Web Page 3.12.
Figure 3-16: Port Security Web Page 3.12.2 Delete MAC Address If you want to delete MAC Addresses, simply follow the procedures shown below: For deleting individual MAC Address Step 1: Select a MAC Address and clink on “Del→” button. The system will prompt you to confirm your action: Step 2: Choose “OK” button to confirm.
3.13 Mirror Port 3.13.1 Using Mirror Port to Monitor Traffic This function allows you to set up a ‘mirror’ port of any specified port(s) or VLAN, such that you can monitor the traffics of the monitored port(s) or VLAN without intervening them. In effect, the traffics on the monitored port(s) VLAN are replicated on the mirror port that you can use a protocol analyzer to analyze the traffic for specific problem. The Port Mirroring screen in Figure 3-17 appears. Figure 3-17: Mirror Port Setup Web Page 3.13.
3.14 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 included the static entry) will be removed from the forwarding table if there is no update within a pre-determined period (1 ~ 128 x 5 seconds). It is useful because the resource of the forwarding table is limited.

5. SWITCH OPERATION 5.1 Address Table The Managed Switch is implemented with an address table. This address table composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port no, etc. This information comes from the learning process of Managed Switch. 5.2 Learning When one packet comes in from any port. The Managed Switch will record the source address, port no. and the other related information in address table.
6. TROUBLESHOOTING This chapter contains information to help you solve problems. If Managed Switch is not functioning properly, make sure the Managed Switch was set up according to instructions in this manual. The Link LED is not lit Solution: Check the cable connection and remove duplex mode of the Managed Switch Some stations cannot talk to other stations located on the other port Solution: The address table may contain older information than of the address table of that node.
