Compare the contents of your SmartGST-801M package with the checklist above. If any item is missing or damaged, please contact your local dealer or reseller for service.
This switch provides an embedded HTML web site residing in flash memory. It of fers advanced management features and allows users to manage the SmartGST-801M from anywhere on the network through a standard browser such as Microsoft Internet Explorer.
The front panel of the switch is displayed as below. There are 2 types of fiber connectors available. These fiber connectors are SC or ST Multi-mode and SC Single Mode. Console Port: Console management can be done via the Console Port. It requires a direct connection between the switch and an end station (PC) via an RS-232 cable.
LED Status Color Description Power On Green Power On On Green The port is successfully connecting with the device on 100Mbps. Blinks Green The port is receiving or transmitting data. LNK / ACT Off No device attached. On Oran g e The port is operating in Full-duplex mode and device is attached.
Attaching Rubber Feet 1. Make sure mounting surface on the bottom of the Switch is grease and dust free. 2. Remove adhesive backing from your rubber feet. 3. Apply the rubber feet to each corner on the bottom of the Switch. These footpads prevent the switch from shock and vibration.
Figure 3-2 Segment Application You can use the SmartGST-801M to connect PCs, workstations, and servers to each other by connecting these devices directly to the Switch. All the devices in this network can communicate with one another. Connecting servers to the backbone switch allows other users to access the server s data.
Figure 3-3 Use fiber ports to extend the distance between workgroups In the above illustration, two SmartGST-801Ms are used to interconnect two small workgroups. By using fiber ports to connect switches, the distance between two switches via fiber cable can be up to 30Km (using a SC Single Mode fiber connector).
After the connection between Switch and PC is finished, turn on the PC and run a terminal emulation program or Hyper Terminal to match the following default characteristics of the console port: Baud Rate: 9600 bps Data Bits: 8 Parity: none Stop Bit: 1 Control flow: None Figure 4-1.

5-1. Web Management Home Overview 1. Home Page. 5-2. Port Status 1. port status State: Displays port status ON or OFF depending on user setting. unlink will be treated as of f .
Duplex status: Displays full-duplex or half-duplex mode. Flow control: Displays Flow Control status enable or disable mode Config: Displays the state of the user settings. Actual: Displays the negotiation result. User can see a single port counter as follows 5-3.
5-4. Administrator Management functions include: IP address, Switch settings, Console port information, Port controls, Link aggregation, Filter database, V LAN Configuration, Spanning Tree, Port Mirror, SNMP, Security Manager, TFTP Update Firmware, Configuration Backup, Reset system, and Reboot.
version. 4. Hardware Version: Displays the switch s Hardware version. 5. Kernel version: Displays default EEPROM value version. 5-4-2-2. Advanced Miscellaneous Setting: MAC Address Age-out Time: Type the number of seconds that an inactive MAC address remains in the switch’s address table.
Priority Queue Service settings: First Come First Service: The sequence of packets sent depends on arrival order. All High before Low: All high priority packets sent before low priority packets. Weighted Round Robin: Select the preference given to packets in the switch’s high-priority queue.
Enable Internet Group Multicast Protocol: enable IGMP protocol IGMP Query Mode: Recognize dif ferent queries from clients or servers to decide which query will be the first priority. The modes are as follows: 1. Auto Mode : Automatically chooses the switch with smallest IP address for the IGMP Query.
The three topologies shown below indicate how the IGMP Query works within a network: 1. This topology is set when the router s IP address is smaller than other Switches in the subnet. 2. This topology is set when the router s IP address is larger than other Switches in the subnet.
3. This topology is used when the Switch s IP address is not the smallest in the subnet. If in Auto mode, the network will cause a Multi- cast Storm from the client IGMP report. The configuration is used to avoid that. Note: We recommend that the switch with the smallest IP address be set as the VOD server.
5-4-4. Port Controls Use this page to modify each port’s status State: User can disable or enable port 1-8. Port 9 is always enabled. Auto Negotiation: Port 1-8 is fixed to disable mode and Port 9 is enabled.
5-4-5-1. Aggregator setting 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. 1. Group ID: Users can create a link aggregation across two or more ports.
5-4-5-2. Aggregator Information When setting an LACP aggregator, view relational information here. 5-4-5-3. State Activity Active (selected) : The port automatically sends LACP protocol packets.
5-4-6. Filter Database 5-4-6-1. IGMP Snooping The SmartGST-801M supports IP Multicast. IGMP protocol can be enabled on the web management s Advanced page. On the IGMP Snooping information page, you can view different multicast groups, VIDs, and member ports.
5-4-6-2. Static MAC Address When you add a static MAC address, it remains in the switch’s address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device’s MAC address when the device is disconnected or powered-off.
5-4-6-4. MAC Filtering 5-4-7. V LAN configuration A Virtual LAN (V LAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the V LAN receive traffic from the same V LAN members.
Support Protocol-based V LAN In order for an end station to send packets to different V LANs, it must be capable of either tagging packets it sends with V LAN tags or attach itself to a V LAN-aware bridge.
Ingress Filtering Ingress filtering lets frames belonging to a specific V LAN be forwarded if the port belongs to that V LAN. The SmartGST-801M has two ingress filtering rules. Ingress Filtering Rule 1: Forward only packets with VID matching this port’s configured VID.
View spanning tree information about the Root Bridge on this screen. View spanning tree status about the switch here. Parameter Description Priority You can change the priority value, a value used to identify the root bridge. The bridge with the lowest value has the highest priority and is selected as the root.
Forward Delay time You can change forward delay time, the number of seconds a port waits before changing from its Spanning- Tree Protocol learning and listening states to the forwarding state. Enter a number 4 through 30. The following parameter can be configured on each port.
Roving Analysis State: Enable or disable the port mirror function. Mirror Ports: The ports you want to mirror. All traffic selected here will be copied to the mirror port. You can select up to 9 monitor ports. To disable the function, select monitor port to none.
Read only: Enables requests accompanied by this string to display MIB-object information. Read write: Enables requests accompanied by this string to display MIB-object information and to set MIB objects. 3. Trap Manager A trap manager is a management station that receives traps, the system alerts generated by the switch.
5-4-12. TFTP Update Firmware The following menu options provide system control functions such as firmware updates and remote system rebooting. * Executing TFTP software * Copy firmware update version image.bin to TFTP software directory. * In web management select administrator TFTP update firmware.
