DES-3326S Layer 3 Fast Ethernet Switch User’s Guide 1 INTRODUCTION This section describes the Layer 3 functionality and Layer 2 and Layer 3 features of the DES-3326S. Some background information about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology is presented. This is intended for readers who may not be familiar with the concepts of layered switching and routing but is not intended to be a complete or in-depth discussion. Layer 3 Switching Layer 3 switching is t

DES-3326S Layer 3 Fast Ethernet Switch User’s Guide Ethernet port to connect to a separate device, which in turn, connects the network to a WAN or the Internet. The DES-3326S can be thought of as 24 Fast Ethernet Layer 2 switching domains with a wire-speed router between each domain. It can be deployed in a network between a traditional router and the intranetwork. The traditional router and its associated WAN interface would then handle routing between the intranetwork and the WAN (th

DES-3326S Layer 3 Fast Ethernet Switch User’s Guide and improve the utilization of the network’s installed bandwidth. The Functions of a Layer 3 Switch Traditional routers, once the core components of large networks, became an obstacle to the migration toward next- generation networks. Attempts to make software-based routers forward packets more quickly were inadequate. A layer 3 switch does everything to a packet that a traditional router does: • Determines forwarding path based on

DES-3326S Layer 3 Fast Ethernet Switch User’s Guide Features The DES-3326S Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. Switch features include: Ports • 24 high performance NWay ports all operating at 10/100 Mbps with Auto-MDIX function for connecting to end stations, servers and hubs. • All ports can auto-negotiate (NWay) between 10Mbps/ 100Mbps, half-duplex or full duple

DES-3326S Layer 3 Fast Ethernet Switch User’s Guide • Store and forward switching scheme. • Full and half-duplex for both 10Mbps and 100Mbps connections. The front-port Gigabit Ethernet module operates at full-duplex only. Full-duplex allows the switch port to simultaneously transmit and receive data, and only works with connections to full-duplex capable end stations and switches. Connections to hubs must take place at half-duplex. • Supports IEEE 802.3x flow control for full-duplex mo
