Introduction

The SmartSTACK ELS100-16TX goes beyond switching basics incorporating unique management features, including, RMON statistics and Broadcast/multicast storm protection, proactive alarms, and both in-band and out-of-band SNMP management.

The SmartSTACK ELS100-16TX uses an ASIC-based switching engine with the ﬂexibility and performance required for today's networking demands.

Ethernet switching allows customer to scale bandwidth by segmenting the network into smaller pieces providing the required amount of bandwidth to individual users or LAN segments. Ethernet switching protects the customer’s investment in Ethernet network hardware by preserving installed shared LAN equipment such as repeaters and hubs, network interface cards, cabling, applications, and network operating systems, while re-deploying high-speed switches where necessary to support today’s bandwidth demands.

The SmartSTACK ELS100-16TX will operate in either 10 Mbps half or full duplex or 100 Mbps half or full duplex modes. Utilization of Fast Ethernet 100 Mbps connections provides a 10 fold increase in data rate per segment while preserving the basic network operation and frame format.

The SmartSTACK 100 ELS100-16TX is protocol-transparent, meaning it can handle different types of network trafﬁc regardless of the network protocol, such as IP and IPX. As the SmartSTACK 100 ELS100-16TX reads addresses from the packets it processes, it builds a dynamic database of addresses called the Bridge Address Table. In this way, the SmartSTACK 100 ELS100-16TX continuously learns the addresses of all connected devices. Consequently, you can add new devices to the network, change device addresses, and remove devices from the network without having to reconﬁgure the SmartSTACK 100 ELS100-16TX.

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 100 ELS100-16TX operates at the Media
