Introduction 1.5 OVERVIEW The SmartSTACK 10 ELS10-26TX is an intelligent Ethernet-to- Ethernet switch that is configured with 25 IEEE 802.3 10BASE-T Full Duplex Ethernet ports, one fixed 100BASE-TX copper connection, one port supporting either a copper or fiber 100 Mbps FEPIM (Fast Ethernet Port Interface Module), and one fixed RJ45 for port monitoring of the 10 Mbps ports. It also includes an RS232C port for out-of-band management. Figure 1-1 shows the front panel for the SmartSTACK 10

Introduction • Operates in either Half Duplex or Full Duplex modes on all ports. • Implements the Spanning Tree protocol (802.1d). • Configured with factory-set defaults for immediate plug-and- play capability (IP address is not configured at factory). In addition, the SmartSTACK 10 ELS10-26 offers the following features that can help you manage and maintain your network: • RMON support. • Configuration and management using the Simple Network Management Protocol (SNMP) with either

Introduction new devices to the network, change device addresses, and remove devices from the network without having to reconfigure the SmartSTACK 10 ELS10-26. The Open System Interconnection (OSI) Reference Model, developed by the International Standards Organization (ISO), identifies the levels of functionality inherent in each of its seven layers. The SmartSTACK 10 ELS10-26 operates at the Media Access Control (MAC) sub-layer of the Data Link layer. Figure 1-2 shows the OSI Refere

Introduction network and when it is granted permission to transmit. In addition, full store and forward switching ensures data integrity, thus preventing network error conditions from being generated throughout the network. Discarding Local Traffic The SmartSTACK 10 ELS10-26 checks all incoming packets for their destination address against the Bridge Address Table. If a packet’s destination address is not on the same network segment as the originating packet, the SmartSTACK 10 ELS1

Introduction By forwarding only packets addressed to devices on other network segments, the SmartSTACK 10 ELS10-26 reduces unnecessary traffic and thereby enhances the overall performance of the network. Note: If the packet address is not found in the Bridge Address Table, it will be forwarded (flooded) to all network segments. Spanning Tree Algorithm The SmartSTACK 10 ELS10-26 supports the IEEE 802.1d Spanning Tree algorithm. The Spanning Tree algorithm converts multiple LANs int

Introduction If a packet’s address is not already stored in the Bridge Address Table, the SmartSTACK 10 ELS10-26 adds the learned address, associated segment number, and a timer value indicating the age of the observation. Consequently, the SmartSTACK 10 ELS10-26 knows the address and associated segment number the next time it sees that address. By using the information stored in the Bridge Address Table, the SmartSTACK 10 ELS10-26 is able to quickly forward each packet to the correct
