1. PRODUCT OVERVIEWDescription
This installation and user guide describes the Cabletron Systems
ELS100-24TXM Ethernet switch. The switch is IEEE 802.1D-compliant
and supports 24 IEEE 802.3u 100Base-TX Fast Ethernet ports. Each por t
can alternatively operate as an IEEE 802.3i 10Base-T port. In addition,
two of the switch’s ports support Fast Ethernet over fiber (IEEE 802.3u
100Base-FX) when a modular daughtercard is installed.
The Cabletron ELS100-24TXM switch automatically learns end-station
addresses from the network and stores them in a Media Access Control
(MAC) address forwarding table. Incoming packets are then forward ed to
the appropriate output port based on the addresses in the p acket. Each
port on the switch operates at full Fast Ethernet wire speed w ith full
address and frame filtering.
The Cabletron ELS100-24TXM switch contains advanced features such
as Remote Monitoring (RMON), IEEE 802.1Q virtual LANs (VLANs),
IEEE 802.1p Class of Service, flow control and broadcast throttling. For
network management, the ELS100-24TXM switch includes a standards-
compliant Simple Network Management Protocol (SNMP) agent. This
agent allows network management station applications to collect and
present status and performance information about a switch as well as
providing the ability to configure and control functions on the device.
Network management can also be performed in-band using the popular
TCP/IP application, Telnet. In addition, a serial console port allows out-of-
band management using a PC or an ASCII terminal. The ELS100-24TXM
switch is desktop or rack-mountable. LEDs on the front panel provide
information about the operating status of the switch. The back panel of the
switch contains the power connector and a power switch. Two fans
maintain ventilation and cooling for internal switch components.
