CHAPTER 1
INTRODUCTION
1.1 PRODUCT OVERVIEW
The SmartSTACK Ethernet ELS10-27TX provides a low cost, high performance
solution for 10/100 Mbps switched networks. The SmartSTACK Ethernet
ELS10-27TX is configured with twenty-seven RJ45 ports supporting twenty-four
autonegotiating 10 Mbps ports and three autonegotiating 10/100 Mbps ports. The
device also features two EPIM-100 slots that allow the user to install up to two
EPIM-100s to provide multimode fiber uplinks (with potential for single mode
fiber). It also includes an RS232C port for local console management.
In ELS10-27TX Version 1.0.1.00, the SmartSTACK Ethernet ELS10-27TX
supports two forms of Virtual LANs. One is the IEEE 802.1Q standard and the
other is a proprietary form that was developed prior to the IEEE standard being
available. The proprietary form is known as Workgroups. Virtual Workgroups are
only supported in the 802.1D mode and VLANs are only supported in the 802.1Q
mode. This manual documents both forms.
Also, modification of existing LCM commands were added that describe how to
set an address limit on a port and how to configure destination IP addresses for
traps. For information on “enable address limit” and “trap control” refer to
Chapter 2, Enhancements to LCM Commands.
This document does not attempt to describe the entire functionality of the
SmartSTACK Ethernet ELS10-27TX product, but only differences between
Version 1.00.xx and Version 1.01.00 of the SmartSTACK Ethernet ELS10-27TX
product.
