1 ABOUT THIS GUIDE Congratulations on your purchase of the DGS-1224T 24 -Port 10/100/10 00Mbps Gi gabit Ether net + 2-Por t Mini GB IC Web-Smart Switch. This device integrates 100 0Mbps Gigabit Et hernet, 100Mbp s Fast Ethernet and 10 Mbps Ethernet network capabilities in a highly flexible package.
2 INTRODUCTION This chapter descr ibes the featur es of the DGS-1224T an d provides some background information abou t Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.
3 In addition, the phenomenal bandwid th delivered by Gigabit Ethernet is the most cost-e ffective m ethod to tak e advantage of to day and tomorrow’s rapidly improvin g switchin g and rout ing inter networking technologies.
4 Switching Technology Another a pproach to p ushing beyo nd the lim its of Ethe rnet technology is the develo pment of swi tching technol ogy. A switc h bridges Ethernet packets at the MAC address level of the Et hernet protoc ol transmitting a mong connec ted Ethernet or Fast Ethernet L AN segments.
5 so broadcast and multicast traffic use val uable network ban dwidth more efficiently. Additional VLAN benefits include: Security: Security is increased with the redu ction of opportunity in eavesdropping on a broadcast n etwork because data will be switched to only those confid en tial users within the VLAN.

40 header. IGMP snooping ca n help re du ce cluttered traffic on the LAN. With IGMP s nooping ena bled glob ally, the Web-Smart Switch will forward IP multicast traffic only to connections th at have group members attached. Figure 34 – Configuration > IGMP Snooping Configuration By default, IGMP is Disabled .
41 for controlling the frequen cy of IGMP traffic on a subnet. Default is 10 seconds. Robustness Variable (1-255 sec): The Robustness Variable allows adjustment for the e xpect ed packet loss on a subn et. If a subnet is expected to be lossy, the Robu stne ss Va riable may be increased.
42 a group is received, a group-specific query is sent to the po rt on which the leave message is received. A timer is started wit h a time interval equal to IgsLeaveProcessInterval. If a report message is receive d before above timer expires, the Leave m essage is dropped.
43 To view the Multicast Entry Table for a given VLAN, press the View button. Figure 36 – Configuration > IGMP Multicast Ent r y Table.
44 Configuration > 802.1D Spanning Tree 802.1D Spa nning Tree P rotocol ( STP) impl ementation is designed t o prevent net work loops t hat could ca use a broadcast storm. Whe n physical links forming a loop prov ide redundancy, only a sing le path will be forwarding frames.
45 Bridge Priority: This value between 0 and 65535 s pecifies the priority for forwarding packets: the lower the value, the higher th e priority. The default is 32768.
46 Path Priority: Select a value between 0 and 255 to specify the priority for a specified p ort for forwardi ng packets: the lower the value, the higher the priority.
47 RX (receive) mode: Duplicates the data that se nd to the source and forwards it to the Ta rget Port. Both (trans mit and receive) mode: Duplicate both the data transmitted from and data send to th e so urce port, an d forwards all th e data to the assigne d Target Port .
