This device integrates 1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install and configure the DGS-1224T Web Smart Switch.
INTRODUCTION This chapter describes the features of the DGS-1224T and some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet.
tomorrow’s rapidly improving switching and routing internetworking technologies. And with expected advances in the coming years in silicon technology and digital signal processing that will enable Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000-Mbpscapable backbone/server connection creates a flexible foundation for the next generation of network technology products.
Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network.
VLAN (Virtual Local Area Network) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and need for routers, using faster switching instead. Other VLAN utility includes: Security, Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN.
Up to 8K unicast addresses entities per device, self-learning, and table aging 512KBytes packet buffer Supports IEEE 802.3x flow control for full-duplex mode ports Supports IEEE 802.1Q-based VLAN Supports IEEE 802.1P-based QoS Supports Port-trunking Supports Port-mirroring Supports Port-setting for Speed/Disable, Flow control and Port priority Support Jumbo-frame setting Supports IEEE 802.
UNPACKING AND INSTALLATION This chapter provides unpacking and installation information for the Switch. Unpacking Open the shipping cartons of the Switch and carefully unpacks its contents.
Leave at least 10cm of space at the front and rear of the hub for ventilation. Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the next section, Rack Mounting. When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching. Figure 1.
Then, use screws provided with the equipment rack to mount each switch in the rack. Figure 3.

Checked “Enable” to use the trunk function, select the ports in each member to be trunk, and click “Apply” to activate the selected trunk group.
Figure 21. Trunk Settings Be sure that the selected trunk setting port must connect to the device with a same VLAN group. Mirror Setting Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary.
Both (transmit and receive) mode: this mode will duplicate both the data transmit from and data that send to the source port, then it will forward to the sniffer port. Figure 22.
IEEE 802.1P QoS Setting To set the Switch QoS base on IEEE 802.1p, Figure 23. IEEE 802.1P-based QoS setting Spanning Tree Setting This Switch supports the 802.1d Spanning Tree Protocol. Every segment will have a single path to the root bridge. All bridges listen for BPDU packets. However, BPDU packets are sent more frequently - with every Hello packet. BPDU packets are sent even if a BPDU packet was not received. Therefore, each link between bridges is sensitive to the status of the link.
STP Function: To selecting enable or disable STP function on the Switch. Bridge Priority: This value between 0 and 65535 to specify the priority for forwarding packets. The lower the value, the higher the priority. The default is 32768. Bridge Max Age: This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information.
Port Path Priority: Select a value between 0 and 255 to specify the priority for a specified port for forwarding packets. The lower the value, the higher the priority. The default is 128. SNMP Setting Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices.
private - Allows authorized management stations to retrieve and modify MIB objects. Traps Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. The Switch generates traps and sends them to the trap recipient (or network manager).
SNMP Community / Trap: To configure the SNMP Community or SNMP Trap configuration. Configure SNMP Community: Figure 25. SNMP Community Setting Add Group: To add a SNMP Community group, press “Add Group” button, the Add SNMP Community configuration window will pop out; fill in the community name and assign the community enable read_only or read_write.
