9032785 Product Overview 11. PRODUCT OVERVIEWDescriptionThis installation and user guide describes the Cabletron SystemsELS100-24TXM Ethernet switch. The switch is IEEE 802.1D-compliantand supports 24 IEEE 802.3u 100Base-TX Fast Ethernet ports. Each portcan alternatively operate as an IEEE 802.3i 10Base-T port. In addition,two of the switch’s ports support Fast Ethernet over fiber (IEEE 802.3u100Base-FX) when a modular daughtercard is installed.The Cabletron ELS100-24TXM switch automatically learns end-stationaddresses from the network and stores them in a Media Access Control(MAC) address forwarding table. Incoming packets are then forwarded tothe appropriate output port based on the addresses in the packet. Eachport on the switch operates at full Fast Ethernet wire speed with fulladdress and frame filtering.The Cabletron ELS100-24TXM switch contains advanced features suchas Remote Monitoring (RMON), IEEE 802.1Q virtual LANs (VLANs),IEEE 802.1p Class of Service, flow control and broadcast throttling. Fornetwork management, the ELS100-24TXM switch includes a standards-compliant Simple Network Management Protocol (SNMP) agent. Thisagent allows network management station applications to collect andpresent status and performance information about a switch as well asproviding the ability to configure and control functions on the device.Network management can also be performed in-band using the popularTCP/IP application, Telnet. In addition, a serial console port allows out-of-band management using a PC or an ASCII terminal. The ELS100-24TXMswitch is desktop or rack-mountable. LEDs on the front panel provideinformation about the operating status of the switch. The back panel of theswitch contains the power connector and a power switch. Two fansmaintain ventilation and cooling for internal switch components.This chapter provides the following information:• Product Description• Features• Front and Rear Panel Component Descriptions• Feature Summaries• Application Examples
