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,...
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-Mbps- capable backbone/server connection creates a flexible foundation for the next generation of network technology products.
Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which don’t compete with each other for network transmission capacity.
Cost Reduction, VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers. Port-based (or port-group) VLAN is the common method of implementing a VLAN, and is the one supplied in the Switch. Features 24×10/100/1000Mbps Auto-negotiation Gigabit Ethernet ports...
