    Terms/Usage In this guide, the term “Switch” (first letter capitalized) refers to the DGS-1224T Web-Smart Switch, and “switch” (first letter lower case) refers to other Ethernet switches. Some technologies refer to terms “switch”, “bridge” and “switching hubs” interchangeably, and both...

  • Page 6: Introduction

    INTRODUCTION This chapter describes the features of the DGS-1224T and provides 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,...

  • Page 7: Fast Ethernet Technology

    In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and 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...

  • Page 8: Switching Technology

    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.

  • Page 9: Features

    so broadcast and multicast traffic use valuable network bandwidth more efficiently. Additional VLAN benefits include: 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. Cost Reduction: VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers.

    Figure 36 – Configuration > IGMP Multicast Entry Table Configuration > 802.1D Spanning Tree 802.1D Spanning Tree Protocol (STP) implementation is designed to prevent network loops that could cause a broadcast storm. When physical links forming a loop provide redundancy, only a single path will be forwarding frames.
  • Page 50 Figure 37 – Configuration > Spanning Tree By default, Spanning Tree is Disabled. If Enabled, the Switch will listen for BPDU packets and its accompanying 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.
  • Page 51 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. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN.

  • Page 52: Configuration > Port Mirroring

    Configuration > Port Mirroring Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of the Switch to another port where the packet can be studied. This enables network managers to better monitor network performances.
