Introduction

This addendum introduces the ELS10-27MDU. It explains the default

configuration and provides the user with the necessary information to

manage and configure this switch. This addendum is provided in

conjunction with the ELS10-27TX User Guide, and does not repeat the

information found in that document. The user should refer to the

ELS10-27TX User Guide for basic switch installation, management and

technical information.

Product Overview

The ELS10-27MDU is a 24 port 10BASE-T switch with three Fast Ethernet

ports. It is a specially modified version of the ELS10-27TX, designed to

provide Internet access in Multiple Dwelling Units (MDUs), such as

hotels, apartment buildings, and dormitories. The ELS10-27MDU has

unique firmware, designed forproduct installationin MDU environments,

in which security and restriction of data traffic between user ports are the

primary considerations. This is accomplished by using the special VLAN

configuration features of the switch.

The default configuration of the ELS10-27MDU is designed to limit traffic

between the ports for purposes of security. This configuration may be

modified as needed. There are 24 10BASE-T ports (user ports), and 3 Fast

Ethernet ports (ports 25, 26 and 27). Port 27 is the uplink port, and Ports 25

and 26 are downlink ports. The downlink ports pass traffic only to an

uplink port, and similarly the uplink port passes traffic only to a downlink

port (or to the user ports on that switch) when multiple ELS10-27MDU

switches are cascaded. The uplink port at the highest level in a cascaded

configuration of switches would typically be connected to a router with a

connection to the Internet. Security is provided by restricting traffic as

follows:

Product Overview

29033276

• Traffic only passes between the 10Mbps ports and the single 100Mbps

uplink port

• Traffic only passes between the 100Mbps downlink port(s) and the

single 100Mbps uplink port on another ELS10-27MDU switch in a

cascaded configuration

• Traffic is inhibited from passing between 10Mbps ports

• Traffic is inhibited from passing between the 10Mbps ports and the

100Mbps downlink ports

• All IP packets not received on the uplink port are ignored

Figure 1 shows a sample configuration with seven ELS10-27MDU

cascaded in three layers.
